First of all, the garden
Choose low level, the soil layer is deep, loose and fertile, the lowest temperature in winter is above -3 degrees, 2-3m×4m, digging 1m× 1m×0.8m, phosphate fertilizer 75kg, 2? -? April.
Second, fertilizer management.
When young trees grow new seeds, the first fertilization should be the first fertilization. The decomposed 5% feces or 5% bran should be added with 0.3% fertilizer, twice a month 1-2 times, making them fat and thin.
Trees are fertilized 3-4 times a year. The stability before 1-2 months, the fertilizer amount accounts for 10-20%, bran, compound fertilizer, bran fertilizer and compound fertilizer; The second fertilizer accounts for 10-20%, mainly bran fertilizer and compound fertilizer; The third fertilization in May was 40-50% year-on-year, and various organic fertilizers were added with 1Kg calcium phosphate fertilizer and 0.5kg compound fertilizer.
Third, plastic surgery
After the garden is deposited, plant seedlings with 3-4 main branches as the first layer of the trunk. There are two main branches on the second floor, and the interval between layers is 50-60 cm. Control within 2.5 meters of the crown. Young trees are pruned in spring with sharp pump combined with tortuous plastic surgery.
Prune the adult trees in time after receiving the goods; Mainly to cut off weak branches, branches, insect branches, dense branches, cross branches and missing branches. As a result, the branches are weak, and there are no leaves. Leave 5cm short piles to intercept them, which will promote new vegetables and strengthen the fruits. Combined with pruning, timely local fertilization promotes new feet.
Fourth, adjustment.
(1) July- In July, in the department for 6-7 months, the directly affiliated branch will pull the directly affiliated branch into this quarter, resulting in the slow growth of the branch; 0.2 kg potassium sulfate, 0.5 dihydrogen phosphate, 0. 1% borax, 300 times isoxazole 1-2 times, and water to promote flower bud differentiation.
(2) rolling relaxation. Sparse leaves 1/3 growing branches, 2/3 bearing branches, young trees, weak trees, multi-flowered, multi-flowered. Going outside can weaken our strength and adopt the principle of receiving later. In late February, the residual flowers have been exhausted, and the young beans and broad beans have been reduced. The program should not be too scattered, so as not to cover the package, 6 per ear, 3-4 pieces per ear, 5 stars 1-3 capsules. (3) Kit. At the beginning of the rectification, it was carried out at an early stage, spraying bags first and then spraying pesticides. When placing a bag, unfold the bag completely, set 2-4 small blades to make the bag contact with the fruit, and then use a small iron wire to tighten the bag.
Verb (abbreviation of verb) pest prevention
When the main disease is disease, high temperature and rainy season are the frequent periods of disease. Three tender mirrors are pumped to the growing period in spring, summer, autumn and winter, and methyl chicken, maca, copper and zinc are used alternately.
The main pests are aphids, paradise, edema and so on. Prevention and control of pyrethroids, pyridoxine, etc., the sixth advantage, the enemy, organophosphorus pesticides, in order to avoid using this pesticide. In the middle and late May and early June, 1 Bomei dog stone mirror is suitable for dry and branch stone mortar, which can drop heaven and earth or less; Larvae that drill into wooden parts can be used for killing. Aphids mainly harm boots and autumn shoots, including interstellar and oxides. Insect-eating mainly harms summer (May-July), when new shoots are killed and returned to tender mirror, flower bud differentiation cannot be carried out.
