There will be one more development after the harvest. There is another 30 to 40 long shoots in the shoots of the shoots. The differentiation of flower buds continues and the shoots are getting fuller. At this time, application of basal fertilizer, spraying of leaves, and pruning of spring will improve the tree nutrient level and cell concentration, which will benefit budding flowers and late shoot development in the coming year.
1, early Shiji fertilizer early post-production basal fertilizer, Qichun can be used in real time to receive the root to avoid frost damage. The sapling ring groove is applied from the outer edge of the planting pit every year to extend the hole and fertilize; the effect of the tree is to apply inorganic fertilizer, the usual fertilization is accepted, the whole garden is applied, or both are replaced every other year, and the appropriate amount is applied. Elemental fertilizers.
2. After the shelter leaves are harvested, the mutual use of the leaves is still being held. Care must be taken to cover the leaves. After the autumn, 0.5% urea and 0.3% potassium dihydrogen phosphate can be sprayed in real time, and potassium dihydrogen phosphate can be sprayed on young trees in particular. Fruit trees that are seriously damaged due to pests and diseases should be sprayed once to develop a conditioning agent that can cover the tree well.
3, prevention and control of pests and diseases negligence early stage orchard pest control disease, will form a large amount of fruit trees deciduous, seriously affecting fruit yield and quality, evidence pests situation, each half of the spraying control, diflubenzuron available on the 3rd 1500? 2000 times liquid, Avi Microcin 3000 times and so on.
4, pruning spring should continue to pull branches, picking the heart, the main branch pulled 70 to 80 degrees, auxiliary branches, leggy branches can be divided into pruning or pulling branches into a 90-degree angle above, in early September all branches, extension branches, The nutrient branches were cut off at the tip of the young sector. The effect of the tree is to eliminate and retreat penalties for the dense branches, intertwined branches, leggy branches, disease and insect branches, and to draw the state of branches under preservation.
5. The application of paclobutrazol is not effective for apple juvenile tree, age-appropriate, or oligo-producing wang tree. It is possible to dig 15-30 cm deep ditch under the main branch, and then pour paclobutrazol into aqueous solution evenly into the ditch, and then cover the soil. .
6. Deeply turning weeding and combining basal fertilizer to turn over the whole garden will help improve the deep soil texture traits and increase nutrient conversion in the soil. The weeds, branches and leaves of pests and diseases, and pests and diseases were wiped out of the park and destroyed in a centralized manner to prevent beneficial insects from spawning and to eliminate the source of the disease and pests the following year.
