Apple tree non-resulting period conservation is more important

Many of the fruit farmers' friends only pay attention to the management of the fruiting period of the apple tree. After harvesting, they only immerse themselves in the joy of harvest, but they neglect to manage the fruit trees before they germinate in the next year. It is precisely this neglect that the harvest of the next year was lost. After an arduous fruiting period, the apple tree has been exhausted in all aspects and needs to be supplemented in a timely manner. After harvesting in the autumn, it should be applied to organic fertilizer. In general, leaf function has not yet declined, and it is appropriate when there is strong photosynthesis. At this point the nutrients return to the roots, can promote root growth and wound healing, is conducive to increase the tree nutrient levels, combined with irrigation, supplemented with late-Akiba tablets spray fertilizer 0.3 ~ 0.5% urea, to delay the aging of the leaves, increase the leaves Photosynthesis time, improve the nutrients stored in the tree, thus ensuring the number of high quality flower buds in the coming year. In addition, conditional orchards can be watered once before freezing, which is effective in preventing freezing damage.

The winter shear of apple trees is a very important part. The winter shear is mainly to adjust the skeleton structure of the tree, balance the growth of various parts of the tree, and regulate the relationship between vegetative growth and reproductive growth. At present, the most suitable trees are: sparse layered crowns, free-spindles, slender spindles, and cylindrical trunks. When pruning, they need to be different from tree to tree, with a focus on the structure of the tree. In order to make full use of light energy, achieve the purpose of high quality and high yield.

Watering in the early stages of fruit sprouting is of great importance. When the permafrost layer is not opened before germination, irrigation can increase ground temperature, increase soil moisture, accelerate root growth, promote sprouting, and ensure flowering rate, especially in the north. At this time, when it is dry, irrigation becomes even more important. . In addition, topdressing before germination, mainly available nitrogen fertilizer, with phosphate fertilizer, can make apple tree flowers neat, improve fruit set rate.
