Autumn and winter fruitful solution "size year"
The land must be deep-fall and not deep-frozen on the orchard once in the early winter. It can be dug in the canopy, dig deep outside the canopy, dig shallowly in the soil, and deepen the soil. In the event that the soil in the mountain orchard is thick and sticky, every adult fruit tree shall be fertilized with fertile soil, loose sandy soil, and 200 kg of vegetable garden soil. The soil to be fertilized in the "Big Nian" tree is to increase the application of nitrogen fertilizer. Before flowering, after flowering, and in the early stage of fruit enlargement, more fertilizer such as urea, ammonium sulfate and ammonium bisulfate are applied to ensure nutrients needed for fruit growth and prevent tree growth. Nutrition is over-consumption and it becomes "small age" in the coming year. After fruit harvesting, 150 kg of farmyard manure and 2 kg of phosphate fertilizer are planted along the canopy around the canopy, which is conducive to the flowering of the “small year†in the second year. For “small-year†trees, reapply germination fertilizer, flower bud fertilizer, stable fruit fertilizer, strong fruit fertilizer and fruit fertilizer, add nitrogen, phosphorus and potassium compound fertilizer, and apply more organic fertilizer such as decomposing manure and urine to ensure flowering results. Need nutrition. In the year of large-scale sparse flowering, the buds should be sparsely flowered according to the characteristics of the varieties, while the flowers with poor fruiting on the upper side should be left with the center flower, and the flowers with low fruit set on the central flower should be left with the flowers. Thinning fruit is generally produced by trees. After falling for a week, it can eliminate poor fruits and retain strong fruits. Then, the fruit and the auxiliary shoots of the fruit trees stay strong. In order to prevent under-fertilization, fruits and vegetables should be planted in a small year. In the flowering period, artificial pollination should be conducted by spraying 0.1-0.25% borax or boric acid solution to promote pollination and young fruit development. At the same time, for the excessively prosperous new shoots and fruit Taiwan secondary shoots, timely picking, twisting, and wiping buds to control their growth and reduce conflicts between water and fertilizers will be conducive to increasing the fruit setting rate of the “small treeâ€.
