First, the scope of application of this regulation 1. This regulation applies to the production of green walnut pollution-free base. 2. The walnut trees are required to be planted on sunny slopes on the sunny side of the sun and some walnut trees are planted on the slopes, slopes 15- 20 degrees is appropriate. Do not exceed 30 degrees. When planting, you should build terraces or make a good preparation. Second, technical indicators Walnuts require full maturity, light nucleus, full grain, no insects, no impurities, no mildew. Three, four seasons management 1. Dormant period management (11-4 months) 1 planted. After defoliation till planting before or after thawing to planting before germination, planting pit 1 Mimi square, spacing 7 meters X9 meters, apply 50 kg of farmyard fertilizer per hole. 2 clean, white. Remove pests and branches Branches, leaves, trunk white. 3 Shuxiong. Artificial sparseness, early sparsely suitable, sparsely 1/2-1 of the total male flower buds 3. 2. Growing season management (April-July) 1 top dressing. In the middle of May before flowering, 40-50 kilograms of manure urine are caught in each strain of the rot. Ring cast or radial fertilization. Trench 30 cm deep. 2 pest control. Adhere to the main agricultural control, chemistry Control measures supplemented by prevention and control, the use of banned pesticides is strictly prohibited. Walnut pests and diseases are less harmful, mainly walnut limb moths harm. Measure: Deeply overturning tree trays in mid-May to mechanically kill overwhelming insects; use 50% phoxim 3000 times solution in early June Spray evenly under the canopy to kill the adult eclosion. Observe the spawning in mid-June. When the rate of ovum reaches 2%-4% When it is sprayed, 2.5% deltamethrin EC is sprayed in 4000 times for foliar spray control, combined with pest control for cultivating and weeding. 3. Harvesting period management (from August to October)1 Harvesting. The harvest time is mid-to-late September (after Bai Lu) and long wood is used for harvesting Rod shot down. Peel the peeled light walnuts. After peeling walnuts for 3-4 days, the peels can be peeled off. 2 drying package. The harvested walnuts are forbidden to be bleached with bleach, washed with water and dried, and picked up to undercooked, infested, moldy, and cracked fruit. Packed in standard double-strand sacks. 3 shaping pruning. During pruning, after harvesting until the leaves just turn yellow, so as not to cause injury flow. The two kinds of tree shapes, sparse layered and naturally happy, are generally used. The sparse formation has a central leadership, divided into 2 levels and 6-7 students Main branch, good ventilation and light transmission, large load. Naturally happy shape without obvious central main branch, forming quickly, results early, backbone Branch arrangements are flexible and easy to master. When pruning, make the skeleton firm, balanced, crown complete, all kinds of branches cut The proportion is appropriate, and the result is that the branches and branches are well-proportioned and reach the periphery without being squeezed, and the internal ridges are not empty, so that the trees have a certain amount of economic output. It can maintain robust growth. 4. Fertilizer Fertilizer Fermented at a temperature of 55~C for more than 7-10 days, the quality of farmhouse fertilizer is 100-200 kg per plant. Application of 667 square meters 2000 kg, the specific method: the use of ring fertilization or radiation trench fertilization, digging width 30 cm, depth 40 cm fertilization ditch. 5. Pest control prevents the soil from deep-falling under the canopy before the soil is frozen and destroys the overwintering sites. Elimination of walnut moths larva.
