Walnut pollution-free production technology
First, the scope of a procedure. The order applies to the production of pollution-free green walnut base. 2. Walnut trees are required to be planted on sunny slopes on the sunny side of leeward, some walnut trees are planted on the ground, and slopes of 15-20 degrees are appropriate, do not exceed 30 degrees, and terraces or well-prepared grounds should be built when planting. Second, the technical indicators Walnut requirements fully mature, photonic nuclear, full grain, no insects, no impurities, no mildew. Third, the four seasons management Management dormancy (November-April) â‘ planting. After defoliation, it is planted before or after thawing and before budding. The planting pit is 1 meter square, and the row spacing is 7 meters X 9 meters. Each hole is used to produce 50 kg of farmyard manure. â‘¡ clean and painted white. Remove pests, dead branches, fallen leaves, trunk white. 3 Shuxiong. Manual sparseness, early sparsely appropriate, sparsely 1/2-1/3 of the total male flower buds. 2. Growing season management (April-July) 1 top dressing. In the middle of May before flowering, 40-50 kilograms of human fecal urine were recovered from each rot of the plant, using circular or radial fertilization. Trench 30 cm deep. 2 pest control. Adhere to the prevention and treatment of agricultural control, chemical control as a supplement, and prohibit the use of banned pesticides. Walnut diseases and insect pests are less harmful, mainly due to the damage of walnut limb moths. Measure: Deeply overturn the tree plate in mid-May to mechanically kill the overwintered mites. In early June, evenly spray 50% phoxim-emulsion 3000 times under the canopy to kill the eclosion adults. Observe the oviposition in mid-June. When the rate of egg fruit reaches 2%-4%, 2.5% deltamethrin EC is sprayed in 4,000 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 the long wood poles are used to knock down the harvest. 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 the pruning period, after harvesting until the leaves just turn yellow, to avoid causing injury. The two kinds of tree shapes, sparse layered and naturally happy, are generally used. The sparse layer has a central leadership, divided into 2 layers, and has 6-7 main branches. It has good ventilation and light transmission, and has a large load. There is no obvious central main branch in the natural happy shape, the formation is fast, the result is early, and the backbone sticks are arranged flexibly and easy to grasp. During pruning, the skeleton should be firm, the growth should be balanced, the crown of the tree should be completed, and the percentage of all kinds of branches should be properly cut. As a result, the branches and branches should be equipped properly so that they would not squeeze on the periphery and the internal cavity would not be empty. This would enable the tree to have a certain economic output, but also Maintain a healthy growth. 4. Fermentation at 55 C under a fertilizer ~ 7-10 days after high manure 100-200 kg per plant, the amount of administration of 667 square meters per 2,000 kilograms, specific methods: using an annular groove fertilizer or fertilizing radiation, digging width 30 Centimeter, 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 overwintering larvae of walnut agama.
