First, the site selection. Concentrated and contiguous areas are selected, and where transportation is convenient, slope orchards should be selected to have a slope of 20 or less, with leeward sunny terraces, terraces and gentle slopes. Flatland groundwater level should be at least 1 meter, so that irrigation and drainage can be done freely and there is no water accumulation after the rain. The effective soil layer of the colonization belt is up to 80 cm and the pH value is around 6.5. Loam or light clay loam with good grain structure and good fertility should be selected, and kiwifruit should not be planted on land with heavy, wet or high groundwater levels. Second, planting seedlings. The planting time was planted in front of axillary buds from mid-October to mid-late November or from February to March of the following year. Planting density according to the spacing of 3 meters 5 meters, 3 meters 4 meters, 2 meters 4 meters. Digging points in the mountains to plant the hole, the length and width of each one meter, 0.6 meters deep. The moderately trimmed seedling roots were placed in the center of the hole and the roots were stretched. After filling, the roots were gently raised upwards and the roots were closely connected to the soil. The depth of the roots and necks was preferably 5-10 cm. After filling, make a 1m diameter tree tray around the seedlings and pour enough root water. Pingba District does not dig a hole, deep-falling and planting high-bay, so that the high-incidence low ditch, and pay attention to winter frost. Third, fertilizer and water management 1, scientific fertilization: fertilizer methods. Kiwi fertilization methods include soil fertilization and foliar dressing. Fertilization of the soil includes annular furrows, radial furrows, gutters, and caverns. Foliar fertilization can be mixed with acidic fertilizers, mainly sprayed leaves. Fertilization in a young garden. Diligent application of thin application of nitrogen fertilizer, with the application of phosphorus, potassium fertilizer. Nitrogen is dominant in spring and summer, and phosphorus and potassium fertilizers are added after the end of summer. The annual fertilization 8-10 times, with the increase of tree age, fertilization depth can be properly increased, the number of fertilization can be reduced to 5-6 times. Single plant 100-400 grams of pure nitrogen. Mature garden fertilization. In the middle of October, the amount of organic fertilizer applied was sufficient to use phosphorus, accounting for 50% of the whole year, and nitrogen consumption accounted for 10% of the whole year; before the bud, in late February and early March, nitrogen was mainly used. 50% of the whole year, irrigation after application; fruit enlargement period (after the second physiological fruit drop, from the end of May to the beginning of June), dominated by potassium, accounting for 50% of the annual, nitrogen accounted for 20% of the full year, phosphorus accounted for the whole year 25%; flower buds concentrated a large number of differentiation period (from late August to early September), mainly potassium and phosphorus, potassium accounted for 50% of the whole year, phosphorus accounted for 25% of the year, supplemented by nitrogen, dosage of 20% of the year. Trace elements are applied as foliar spray and applied at a concentration of 0.1-0.3%. 2. Water Management: During the fruit growth period (mid-May to late September), about 900 millimeters of natural rainfall is needed, otherwise manual irrigation is required. In the drought-sudden years of winter and spring, combined with fertilization and irrigation before germination, timely drainage during rainstorm in summer, and continuous high temperature and drought in autumn, if there is no rain for 5 days, timely irrigation should be conducted to ensure high yield and high quality. Fourth, plastic pruning 1, shaping: single trunk (about 1 m high), 2 main branches (within 1.5 meters in length), 4 2 main branches (within 1.8 meters in length) 8 3 main branches (by The results of the mother branch processing, picking up 1.8-2.0 meters high, completed within 2 years. 2. Summer pruning: wipe the excess vegetative branches on the mother branch as a result, according to the time, rational use of the results of the base of the mother to stand upright stout branches and vegetative branches, when the number of erect stout vegetative branches is insufficient, they will be cultivated into The results of the following year's mother branch; the results of reasonable branch topping, according to the results of the branches on each bud to retain 2-3 normal leaves is appropriate; on the upright branches in the autumn before and after the harvest, the short cut in the weak place, to promote shoots and flower bud differentiation . The ratio of leaf to fruit is better than 5:1. 3, winter pruning: the results of the year the mother left 2-4 buds short cut, promote vegetative branches. Sparse upright branches are removed, the upright branches left are pulled down in an arc, and are equidistantly fixed on the wire. V. Flower and fruit management 1. Artificially assisted pollination: Collect pollen storage. Collect the male flower that was opened in the morning on a sunny day. Collect it together with the corolla and calyx. Spread it thinly and dry it in a cool, ventilated and cool place. Let it dry for about 6-8 hours. After the pollen burst, pollen was screened out and stored in a cool, ventilated place. One of the commonly used methods of pollination is to use a writing brush to cover the pollen and dip it directly on the female stylar head; second, to prepare the pollen solution (1 gram of pollen, 20 grams of white sugar, 400 grams of water), and spray the stigma after fully shaking. 2, thinning fruit: sparse small fruit, fruit injury, skew fruit and pests and fruits, leaving large fruit, normal fruit. A maximum of 3-6 fruit per fruiting branch. 3, fruit bagging: bagging period is appropriate for the first half of June. Prior to bagging, the orchard shall spray 1-2 times in full according to the occurrence of local pests and diseases. Immediately after spraying, choose normal growing and robust fruits for bagging. Paper bags should use windproof, rain-proof paper bags with good air permeability. About 10 days before harvest, the bags were picked. VI. Pest control 1. Prevention and control of major diseases Flower rot: Before germination, a 1% lime equivalent Bordeaux mixture was sprayed, and germination was applied until the flowering period was 100 mg/L of agricultural streptomycin. Ripening rot: After the fruit is set, use 50% carbendazim WP 1000 times solution, or 50% of Captagon 1000 times solution. Root rot disease: heavy cutting of leaf shoots on the ground, drying and dehumidification, scraping of pathogens, wound dressing (with 50% thiophanate-methyl or 65% Zeoxin 50-100 times), soil disinfection, backfill sand. 2. Prevention and control of major pests Chafer: Clearing weeds around nurseries and orchards and destroying their living environment can be thoroughly controlled. When the trees live in danger, they beat and kill after the shock, and 2-3 days before flowering, the canopy is sprayed with a 50% phoxim emulsion 700-1000 times, sprayed every 10 days or so after spraying, and even sprayed 2- 3 times. Scale insects: Scraping or spraying 5 Baume degrees lime sulfur agent in winter. From late April to early May, the nymphs hatch and prosper, spray 25% quinoline 600-1000 times, or 80% dichlorvos 1000 times. , Or 40.7% Lost 800-1500 times liquid timely prevention and treatment. Ye Yan: Should be controlled during the nymph stage, commonly used agents are 80% dichlorvos 800-1000 times, or 10% imidacloprid 2000-3000 times spray control.
