Origin Environment and Geomorphology The main soil types in Shiping County of Yunnan Province are paddy soil, alluvial soil, lateritic red soil, mountain red soil, sandy loam soil and liver stone soil. The terrain is high in the northwest, low in the southeast and concave in the middle. The mountains tend to move from southwest to northeast. Lao Heishan is in the northeast, Daleng Mountain is in the south, Broken Longshan Mountain and Nibaimuke Mountain are in the northwest, and Yanwa Mountain and Bijia Mountain are in the middle. Mountains and rivers alternate with each other, with large height difference and beautiful scenery. The mountainous area accounts for 95% of the total land area of the county; There are four dams in the flat land, such as Shiping County Dam, Baoxiu Dam, Dam Core Dam and Longpeng Dam, and the flat land area only accounts for 5% of the total land area of the county. The highest elevation in China is 255 1.3m, the lowest elevation is 259m, and the relative height difference is 2,292.3m It is a typical three-dimensional terrain. The most suitable height of Myrica rubra in Shiping is 800- 1800 meters above sea level. Hydrological situation Shiping County belongs to the watershed of the Red River and the Pearl River Basin, with 35 rivers and ditches, rich in water resources and clean in water quality, free from human and industrial pollution. The main river Red River runs through the county from northwest to southeast. There are two natural lakes, Yilong Lake and Chirui Lake, which are one of the nine plateau lakes in Yunnan Province. The water surface is 43.4 square kilometers, and the storage capacity1.10.02 billion cubic meters. There are 38/kloc-0 dams, with a storage capacity of 3,260 cubic meters. Climate: Shiping County belongs to the subtropical mountainous climate zone of Yunnan Plateau. Because it is located on the plateau, the low latitude and the tropic of cancer pass through the southern region, and the vertical difference of terrain is significant. At the same time, influenced by the dry warm air currents in the southwest Indian Ocean, the southeast Pacific Ocean and the northwest mainland, the monsoon climate is typical, with the climatic characteristics of "four seasons in summer, one rain in autumn". The annual average temperature 18.2℃, the highest temperature over the years is 32℃, and the lowest temperature is -3.9℃. The average temperature in the hottest month (July) is 27.7℃, and that in Leng Yue (65438+1October) is 9. 1℃. The effective accumulated temperature ≥ 10℃ is 5950.0℃ and the frost-free period is 3 16 days; The annual sunshine hours are 2020-2200 hours, the sunshine percentage is 52%, and the effective rate is 83%. The annual radiation is 135.2 kcal/cm2; The annual rainfall is 850- 1 100 mm, of which the rainfall in May-10 accounts for 8 1.3% of the annual rainfall. Superior eco-geographical conditions, suitable soil and climate provide an ideal natural environment for the development of Myrica rubra industry. Shiping, the historical origin of Myrica rubra, is one of the main distribution areas of wild Myrica rubra in China. It is rich in wild resources. Four wild Myrica rubra varieties, including Dwarf Myrica rubra, Fine Myrica rubra, Semi-Jingmei and Wu Xiongmei, have been discovered. Since ancient times, Myrica rubra has been one of the fruits eaten by people of all ethnic groups in Shiping County for hundreds of years. In the 12th year of Qing Qianlong (1747), Shiping County Records was recorded, and in the first year of the Republic of China (19 12), Shiping County Records was edited by Yuan Jiagu. Before 1980s, the artificial planting and grafting of wild Myrica rubra in Shiping County, due to its small scale and low yield, had no significant economic benefits. Since 1980s, Shiping County has introduced seven varieties from Zhejiang and Fujian, including Crystal Plum, Dongkui, Shui Mei, Horseshoe Plum, Dingao Plum, Charcoal Plum and Late Rice Myrica rubra, and hybridized them with local wild Myrica rubra. After years of experiments and purification, Dongkui and horseshoe plum were selected as the main varieties suitable for local cultivation. 1985, Myrica rubra was planted in Shiping County (the first county in Yunnan Province to introduce Myrica rubra from Zhejiang). 199 1 year successfully bore fruit, which was large, colorful and moderately sweet and sour. From 65438 to 0993, after years of trial planting and exploration, the Myrica rubra industry in Shiping County was appraised as "good quality, good taste, large pulp, small pit, bright color and moderate sweetness and sourness" by relevant experts in Yunnan Province and Prefecture, and was popularized and introduced in many places in the county in the same year. The Myrica rubra industry in Shiping County has developed into a "Myrica rubra eco-tourism" integrating leisure and entertainment, and the "Myrica rubra Festival" is held every May, attracting many tourists from inside and outside the province to watch and taste. Production in 20 10, Shiping County planted 6,666.7 hectares of Myrica rubra, including 4,000 hectares in Dongkui and 2,666.7 hectares in Eleocharis tuberosa, with an annual total output of 75,000 tons, making it the county with the largest planting area and output in Yunnan Province. In 20 13 years, Myrica rubra in Shiping has grown to more than 60,000 mu. In 20 17, Shiping County was certified by the Ministry of Agriculture as two green food production enterprises and seven pollution-free agricultural products production enterprises. The total planting area of Myrica rubra in the county is 128300 mu. There are about 100 bayberry production and marketing enterprises in the county, and more than 6,000 fruit farmers are contacted. Product Honor In 2002, Shiping County was recognized by the Ministry of Agriculture as the "Famous Base of Myrica rubra, a subtropical crop of the Ministry of Agriculture". People's Republic of China (PRC) and the Ministry of Agriculture approved the registration and protection of geographical indications of Yangmei agricultural products in Shiping on February 24th, 20 10. Scope of protection of geographical indications Shiping County is located in the south of Yunnan Province and the west of Honghe Hani and Yi Autonomous Prefecture. The geographical coordinates are east longitude10208' 00 "-north latitude10243' 00"-north latitude 2319' 00 ". The county covers an area of 3037 square kilometers. The maximum horizontal distance from east to west is 59 kilometers, and the maximum vertical distance from north to south is 88 kilometers. The waxberry producing areas in Shiping County include six towns, namely Yilong, Baoxiu, Simba, Longpeng, Da Qiao and Xincheng. Quality and technical requirements (1) Garden selection: Choose sandy red and yellow soil with loose soil, deep soil layer, good drainage, gravel, pH value of 5.5-6, slope below 30 degrees, and elevation of 800- 1800 meters, and build the garden by using horizontal terraces or contour fish scale pits. (2) Variety selection: select excellent varieties that adapt to local environmental conditions and show good economic characters and resistance, such as Dongkui and Eleocharis tuberosa. (3) Seedling planting: planting time: 65438+from late February to early February. Planting density: according to the land conditions of the garden, the sloping land with deep soil layer should be sparsely planted, and the soil layer should be thin or densely planted with sufficient light. Dongkui species is 5m× 6m, and water chestnut plum is 5m× 5m. Planting method: dig pits with a width of 1 m and a depth of 0.8 m, apply 50 kg of organic fertilizer or 4 kg of cake fertilizer to each pit, add calcium superphosphate 1 kg, mix well with rich soil to fill the pits, and cover them with fertile topsoil with a thickness of 20 cm. When planting, put the seedling in the center of the hole, stretch the root system, correct the seedling, keep the upper part of the seedling upright, then fill in fine soil and tamp it hard. The planting depth should cover the marital joint. Then pour enough "root-fixing water" and cover the tree tray to reduce water evaporation, maintain rhizosphere humidity and improve the survival rate. (4) Water and fertilizer management: water management: timely irrigation in dry period, especially in high temperature and dry period. Pay attention to drainage and flood prevention in spring and rainy season to avoid waterlogging. Fertilizer and water management of young trees: During the growing season from March to August, thin fertilizer should be applied repeatedly, with quick-acting nitrogen fertilizer such as urea or appropriate compound fertilizer of nitrogen, phosphorus and potassium as the main fertilizer. After the newly planted young trees survive, apply quick-acting thin fertilizer in time, half a month before pulling out bamboo shoots in spring, summer and autumn, and apply urea 0. 1 kg per plant. Due to the weak resistance of young trees, the soil moisture content is required to be sufficient when fertilizing, which can be applied before and after the rain or poured into the water. After three years of growth, 0.3-0.5 kg of urea and 0/-2 kg of potassium sulfate/kloc-0 are applied to each plant every year. Pay attention to less nitrogen and more potassium in fertilization after fruit bearing, and control the growth to promote fruit. Fertilization methods are mostly ring-shaped and disc-shaped fertilization to promote the root system to extend outward and expand the crown. Fertilizer and water management of fruit trees: the principle of fertilization for fruit trees is to increase potassium, reduce nitrogen and control phosphorus. Fertilize 2-3 times a year, 1 time is 2-3 months before germination. Potassium fertilizer is mainly combined with nitrogen fertilizer to meet the nutrient requirements of bayberry growth, flowering and fruit growth and development. In mid-May, the second fruit-strengthening fertilizer was applied, mainly available potassium fertilizer, to supplement the nutrient demand of fruit growth and development and improve fruit quality; The third time is from June to July after fruit picking, with organic fertilizer as the main material, quick-acting nitrogen fertilizer as the supplement, and timely supplementing tree nutrients, accounting for about 30%, 30% and 40% respectively. Topdressing outside roots: Spraying 0.2% borax solution at flowering stage and 0.2% urea plus 0.3% potassium dihydrogen phosphate or high-efficiency rare earth liquid fertilizer 1200- 1500 times at fruit growth stage can promote leaf growth, improve photosynthesis and improve fruit quality. (5) Shaping and pruning: young tree shaping: the tree shape is better with natural shape. In the first year after planting, the first main branch is selected to be 20 cm away from the ground, and then the second and third main branches are reserved every 15-20 cm; In the second year, the immature autumn shoots are cut off from the extended branches of the main branch, and all the side branches on the main branch are cut short, leaving the first branch 60-70 cm away from the main branch; In the third year, the second auxiliary branch is selected on the main branch, and the distance between the first and second auxiliary branches is 60cm；; In the fourth year, continue to extend the main branch and the secondary branch, and select the third secondary branch about 40 cm away from the second secondary branch. When cultivating the main branch and auxiliary branch, we should select and keep the large side branch in time, and complete the plastic surgery in about 5 years. At the same time, the method of stretching branches in June-July was used to alleviate the tree vigor and promote the premature birth of Myrica rubra. Pruning fruit trees: timely and moderate pruning can improve the fruit-bearing performance and excellent fruit rate of Myrica rubra, and it should be pruned twice. For the first time, after the fruit is picked (at the end of June and the beginning of July), the top vertical branch (skylight), the cross branch of two trees, the lower mopping branch and the dense branch of the crown are sawed off, so as to achieve the effects of promoting summer shoots, renewing inner branches and increasing fruiting branches; The second time was in February of the following year, mainly pruning tender branches, cutting off pests and diseases, dead branches, dense branches, vertical branches and late autumn branches, cutting off some non-flowering trees and cutting off some flowering trees; For flourishing trees that grow too fast, have low fruit setting rate and low yield, methods such as girdling, girdling, back-buckling and root cutting can be adopted. (6) Management of flowers and fruits: Short-cut fruiting branches and sparse flowers: For trees with too many flowers, pruning in spring is generally combined, and the whole tree is evenly short-cut 1/5 fruiting branches, and the redundant fruiting branches, especially the thin and dense fruiting branches at the upper part of the crown, are sparse. Artificial fruit thinning: fruit thinning is carried out in 2-3 times, 1 time is 20 days after flower withering, and the fruit is as small as peanuts, mainly thinning dense fruit, small fruit and bad fruit, and leaving about 4-6 branches per fruit; For the second time, when the transverse diameter of fruit is 1 cm 30-35 days after flower withering, thin the small fruit and bad fruit again, leaving about 2-4 fruit branches per fruit; 40-45 days after flowers wither, two fruits are left on average in each fruiting branch, among which 3-4 fruits are left in the stout long fruit branch with a length greater than 15cm, 2-3 fruits are left in the middle fruit branch (5- 15cm), and 1 fruit is left in the short fruit branch with a length less than 5cm. (7) Integrated pest control: Control requirements: protect the normal growth of Myrica rubra, enhance the resistance of trees, use pesticides scientifically, improve the control effect, control environmental pollution, promote ecological balance and save costs. Control principle: According to the policy of "prevention first, comprehensive management", based on agricultural control, according to the occurrence law of pests and diseases, chemical control, biological control, physical and mechanical control and other measures are reasonably used to control pests and diseases economically, safely and effectively. Prevention and control measures: first, strictly implement the plant quarantine system stipulated by the state to prevent the spread and spread of quarantine pests and diseases. The second is to combine pruning, cut off pests and dead branches, remove fallen leaves, and burn them after spring to reduce the source of pests and diseases. The third is to strengthen cultivation management, enhance and improve the resilience of trees, and create environmental conditions that are not conducive to the occurrence of pests and diseases. The fourth is to protect and utilize natural enemies, give play to the role of biological control, eliminate harmful organisms with beneficial organisms, expand the application scope of insect control and bacteria control, and maintain the ecological balance of nature. Fifth, strengthen the prediction of pests and diseases to achieve timely and accurate prevention and control. Sixth, it is necessary to choose pesticides with high efficiency, low toxicity, low residue and low lethality to natural enemies, and reasonably use different pesticides alternately to improve the lethality to pests and reduce their drug resistance. Main pest control methods: cancer: before picking new shoots, cut off diseased branches and dead branches, burn them, and then spray 1: 2: 200 Bordeaux solution; Strengthen the protection of trees and try to avoid man-made mechanical damage in the process of fruit harvesting and cultivation management; From March to April, before the spread of bacteria in the cancer, the cancer was removed with a sharp knife, and the wound was smeared with copper sulfate 100 times or 72% agricultural streptomycin 3000 times, and smeared with 1 time every half month. Prevention and control methods of brown spot disease: cleaning the fallen leaves of orchard in winter, centralized burning or deep burial to reduce the source of overwintering disease; At the initial stage of the disease, the canopy was sprayed with 50% carbendazim wettable powder 800- 1000 times or 700% thiophanate-methyl wettable powder, every 7- 10 days, 1 time after fruit harvesting. Every year 10 to the end of February of the following year, spray 3-5 degrees of lime-sulfur mixture on seriously ill bayberry, and the effect is good. Control methods of scale insects: combining pruning, pruning dead branches and live branches with high insect population density in spring, and centralized burning to reduce insect sources; Spraying pesticides in the first generation nymphae stage from May to June (when fruits grow, no pesticides are sprayed at this stage) and in the second generation nymphae stage from July to August, using 25% chlorpyrifos powder 1000- 1500 times or 100% imidacloprid EC 1000. Control methods of leaf roller moth: manually remove or cut off damaged branches and burn them centrally; In larval stage, 20% pyrethroid EC can be sprayed 2000-3000 times or 10% imidacloprid EC 1000 times. (8) Fruit harvesting requirements: When harvesting bayberry fruits, it is required that all varieties and grades of fresh bayberry fruits must be fresh and clean, free from peculiar smell, pests and diseases, carefully picked by hand, and have normal development and maturity required for storage or market. When picking, put it down gently, put it into containers according to the classification index, and pack it when picking to reduce extrusion. Each basket (reed) shall not exceed 10 kg. (9) Requirements for production records: Production files shall be established in the production process, and the names, usage times, frequency, dosage, usage methods and harvest date of the inputs shall be comprehensively recorded and properly kept. The geographical indications of agricultural products are uniformly used for special signs (the name of Shiping Myrica rubra is combined with the logo pattern). The exterior of the transport packing box (basket) shall be printed or affixed with labels, indicating the trademark, product name, variety, weight (gross weight and net weight), packaging date, product implementation standard number, etc.
