Jingyuan county regards Lycium barbarum planting as the pillar industry of enriching the people and strengthening the county, based on the advantages of regional resources, taking the base as the driving force to cultivate the advantageous industry of Lycium barbarum. At present, the planting area of Lycium barbarum has reached 28,800 mu.
From 65438 to 0999, the cultivation technology of Lycium barbarum in Jingyuan County began to be planted and popularized in rural areas in northern China. Due to the obvious economic benefits, Lycium barbarum planting soon spread in several towns in the north. By the end of 2006, the planting area of Lycium barbarum in the county reached 7800 mu. This year, Jingyuan County regards the expansion of planting area of Lycium barbarum as an industry to increase farmers' income, which is included in the overall plan of "expanding three industries and building six bases", and plans to plant 20,000 mu of Lycium barbarum in six towns and villages in the north. The county party committee and government actively coordinated the financial sector to lend 8.25 million yuan to support industrial development, and made every effort to promote the construction of Lycium barbarum base through county-township linkage, real help, land planning and responsibility to people. A science and technology service team has been set up, with technicians stationed in the countryside, training in time, and in-depth guidance in the fields, providing a series of quality services in seedling selection, fertilization, planting and pruning. * * * has held 38 training sessions (times) in Lycium barbarum planting village, trained more than 4,800 people, distributed more than 10000 copies of materials free of charge, distributed 6,000 copies of high-yield cultivation techniques of Lycium barbarum, and presented 60 CDs of Lycium barbarum technical lectures. Planting 2 1000 mu of Lycium barbarum laid a solid foundation for the scale and standardization of Lycium barbarum base construction.
Jingyuan Lycium barbarum is listed in large quantities in mid-July every year, and the main variety is "Ningqi No.3", a new large fruit Lycium barbarum variety. I supply Lycium barbarum all the year round, and we strictly control the quality in the processing. From the beginning of collection, we can purchase according to documents and output, and establish collection files. And promised: it is not that the local area does not collect, it is not that farmers collect it themselves, and Lycium barbarum containing sulfur dioxide does not collect it. Ensure that merchants can really receive Lycium barbarum, and overcome the disadvantage that other merchants can't confirm the origin when they buy it from the market. And provide customers with one-stop services such as acquisition, packaging and transportation.
The origin of Jingyuan Lycium barbarum covers 9 townships in Jingyuan County, Gansu Province, namely Jing 'an Township, Wuhe Township, Dongsheng Township, north beach Township, Yongxin Township, Shuanglong Township, Shimen Township, Liu Chuan Township and Dalu Township.
I. Diversity
Traditional local medlar.
Second, the site conditions
Within the range of origin, the altitude is 1300-2300m, the soil is irrigated silt or calcareous soil, the texture is sandy loam or loam, the pH value is 7.5-8.5, the organic matter content is > 1%, and the total salt content is < 1%.
Third, cultivation management.
1. Seedling raising: Lycium barbarum L. adopts hardwood cutting and softwood cutting for seedling raising. From mid-March to early April, the sap began to flow, the buds did not germinate, and the soil thawed more than 20cm. It is suitable for cutting seedling from late June to late August.
2. Planting time: it is divided into spring planting and autumn planting. Spring sowing is from late March to early April; Autumn planting is from late June 65438+ 10 to early October165438+10 (before winter irrigation).
3. Planting density: the density is 2668 ~ 3330 plants /hm2.
4. Fertilizer and water management: organic fertilizer should be more than or equal to ≥55t/hm2, appropriate topdressing nitrogen fertilizer should be less than or equal to1.5t/hm2, and timely irrigation should be carried out in case of drought.
5. Shaping and pruning: through fixed stem and short cut pruning, the natural semicircle is mainly used to ensure the ventilation and light transmission of the crown.
6. Environmental and safety requirements: The use of pesticides and fertilizers must comply with the relevant provisions of the state and must not pollute the environment.
Fourthly, picking and drying.
1. Picking time: from mid-June to mid-October.
2. Drying: clean the collected fresh fruit, dewax it in time, then naturally dry it, dry it until the peel shrinks, dehydrate it, then dry it with hot air, and remove the fruit stalks to get dried fruit. The hot air drying temperature is controlled between 45℃ and 60℃, and the moisture content of dried fruits is controlled below 13.0%. The technological process is: fresh fruit → cleaning → dewaxing → drying → cleaning → hot air drying → stem removal → dried fruit.
The quality characteristics of verbs (abbreviation of verb)
1. Sensory characteristics: the fruit is flat spindle-shaped or oblong, with orange or red skin, obvious white stalk marks at the base, thin and shriveled skin, small and few seeds and sweet taste.
2. Physical and chemical indexes: dried fruit weight range: 250 ~ 600/50g. The polysaccharide content is ≥ 3.65438 0%, and the total sugar content is ≥39.8%. Edible rate 100%, drying rate ≥20%.
3. Quality and technical requirements such as safety: Quality and technical requirements such as product safety must comply with relevant national regulations.
