1. Production management technology: 1. Early spring excavation and shelf management. When the average surface temperature is about 10 degrees (apricot trees bloom), grapes begin to be unearthed and put on shelves. First, remove the plastic film, and spray branches, vines and planting ditches with 5-degree sulfur mixture to eliminate all kinds of egg germs. After the grapes are put on the shelves, apply 3000kg∕666.7㎡ of decomposed chicken manure or pig and sheep manure, then mix in 100 kg of biological bacterial fertilizer, 60 kg of tri 15 compound fertilizer and 20 kg of urea, and immediately pour fertilizer water and thoroughly. When the surface is dry, turn over the planting ditch from beginning to end, so that the manure can be fully mixed together, and it can also play the role of heating and ventilation. Co2 is applied to early budding, early budding, coring, thinning flowers and increasing leaves. In early spring, when the buds grow to about 2 cm, the buds are applied, and all the main vines below 40 cm are smoothed, leaving 6-8 strong buds per meter, and the rest are smoothed, and the strong buds close to the main vines are selected. Those left for a long time in the previous year or need to widen the air duct and light path should be erased together this time to reduce the consumption of nutrients. When the root pressure is high, strictly cut off the main vines or branches with scissors to prevent bleeding from the wound. When you see new ears, young trees should leave 6-7 new ears per meter, and adult trees should leave 5-6 new ears for fixed branches. Grape seedless cultivation does not need pollination, as long as the nutrition is sufficient, it can ensure fruit setting, so it is required to pick the core early and re-pick it. When picking the core, the smaller the leaves are, the bigger the growth will be. It is best to pick the core when the fingernail size of the upper leaves or coins are large and small. Results Two leaves were left before inflorescence, and six leaves were taken from vegetative branches. After the branches are fixed, the ears should be thinned immediately, and strong branches should be left per meter of vines, three inflorescences should be left, and the rest should be removed. According to the local climate, more ears can be reserved in advance to prevent strong winds from blowing off or accidentally knocking them off in production management, thus making up for the losses caused. After denucleation, all the secondary buds germinated in the axils of bearing branches and vegetative branches are removed, and concentrated nutrition promotes the rapid growth of leaves, so that all leaves can make nutrition through photosynthesis during flowering to meet the needs of flowering and fruit setting. The bigger the leaves before flowering, the better the fruit setting rate and seedless rate, and the bigger the fruit grows in the later stage. After fruit-setting, let the secondary auxiliary buds germinated at the top of winter buds continue to grow. When they reach 5-6 leaves, take off the top and erase all the auxiliary buds that grow later until the old autumn. Extend vines, keep double vines (double vines here refer to vines that have been used for two or three years, but will not be used after three years), increase leaf area, and pick lightly or not. Water the ground immediately after topping, once every 7 days, with 0. 1 kg urea per plant, preferably in the form of flooding, and then loosen the soil to facilitate root respiration and promote rooting. Spraying fertilizer on leaves every 4-5 days from coring, mainly 0.3% urea (65438+ 0.5 kg of water and 0.05 kg of urea), and adding chitin microbial inoculum to enhance the comprehensive disease resistance of trees (it must be added after each foliar fertilization). Urea water should also be sprayed at the full flowering stage, and fertilization should be ensured at the initial flowering stage to promote seedlessness and improve the fruit setting rate. Spraying 0.3% urea water on leaves at full flowering stage in dry years will interfere with pollination and increase nutrition. Only with new varieties and good quality can we sell them at a good price and have higher economic benefits. The output of 666.7 is 1500-2000. Excessive yield will affect the taste, color and delayed ripening of fruits, so we must strictly control the yield and ensure the quality of fruits. 3. Pay attention to the shaping of flowers and fruits and the management of water and fertilizer. Before flowering, pinch off the secondary spike and the secondary branch, keep the spike tip still or remove a little, and ensure 14 per inflorescence. Especially after fruit setting, do a good job of ear shaping, remove small fruits, deformed fruits and diseased fruits, ensure that the number of fruits per ear is 40-50, and ensure that the single grain weight reaches more than 13g. When the fruit grains grow to the size of peanuts, cut off the fruit grains protruding from the surface of the ear in time to ensure the beautiful shape of the ear. The ears trimmed in this way are in the shape of long sticks or pineapples, which are very beautiful. At the early flowering stage, medium and small fertilizers were applied once, mainly quick-acting nitrogen fertilizer, micro-fertilizer spraying chitin and Jundukang; The flowering period is small, and it can be bred once, as above. 4. Time and method of using non-nuclear agent. The seedless agent is 1 produced by Liaoyang Forestry Department, which is divided into pre-flowering agent and post-flowering agent. The preparation is safe, non-toxic, broad-spectrum and efficient. Pre-flowering agent should be used 5-7 days before flowering. Choose sunny days and add 6 kilograms of water to each bottle. The function of pre-flowering agent is to interfere with pollination, promote seedlessness and improve fruit setting rate. After dipping the inflorescence, apply fertilizer water once and spray foliar fertilizer. After-flowering agent should be used within 5 days when 90% of flowers fall off, that is, stamens and pistils see most of the stems fall off after the corolla falls off, and it is most suitable to touch the ear of mung bean when the whole ear is large and there are no big or small grains. Choose sunny days as soon as possible, 9 kg of water per bottle. The function of post-flowering agent is to enhance cell activity, promote cell division and vertical and horizontal elongation, so as to rely on exogenous hormones to promote cell division and growth, promote fruit expansion and improve fruit setting rate without endogenous hormones. Apply 1 fertilizer water immediately after soaking, spray foliar fertilizer once every 7 days, spray 0.3% urea water once every 5 days until the fruit softens, and then spray potassium dihydrogen to promote fruit coloring, flower bud differentiation and branch maturity. Bagging grapes is an important measure to produce pollution-free products, which can not only prevent dust and pesticide pollution, but also prevent the harm of germs and pests, and improve the appearance quality and internal quality of fruits. Bagging is carried out about 20 days after flowering. Before bagging, spraying 1 times broad-spectrum fungicide to control downy mildew and white rot of grapes, spraying 50% thiram 3000 times and 50% fungicidal 3000 times on the ear. Bag the medicine immediately after drying, and you can choose white paper bag or new grape bag. During this period, the focus of leaf protection is to prevent downy mildew, especially in July. 6. The main management task from fruit setting to softening is to make the ear grow rapidly, prevent fruit diseases and protect leaves. Fertilize water immediately after fruit setting, apply 80- 100 kg of compound fertilizer and 20 kg of urea per mu, then apply fertilizer water every 7- 10 days, and apply special fertilizer for grapes twice continuously; Before softening, apply 40 kg of compound fertilizer and 30 kg of potassium sulfate per mu, and spray organic potassium foliar fertilizer with bactericide on the leaves. 7. In the management of fruit coloring period, it is important to apply farmyard manure and phosphorus and potassium fertilizer, protect leaves, unpack bags before harvesting, normally color them in bags, and harvest them late at the right time to improve fruit coloring and sugar content. 8. Shearing wool in winter and taking off the shelf for wintering and cold protection can be managed according to Jufeng. 2. Summary: In early spring, we should focus on the prevention and control of ear stalk brown blight, gray mold and white rot, and the prevention and control of pests such as green blind stinkbug and thrips; Prevention and control of downy mildew and white rot in the middle and late stage. Adhere to prevention throughout the year. Spraying 1 5 Be stone sulfur mixture or 1000 times biological pesticide Yunju before putting on the shelves; Spraying biological pesticide matrine 1500 times in the second and third leaf stages after grape leaf spreading; Before flowering, spray 68.75% easily water-retaining dispersible granule 1000- 1200 times or 20.67% Wanxing EC 2000 times, every 12- 15d 1 times, and spray * * twice. When downy mildew occurs, spray 2000 times of Dupont Quick Killing Liquid. If it is serious, spray it twice.
