Apple tree non-productive maintenance is more important

Many fruit farmers often pay attention to the management of the apple tree during the fruiting period. After harvesting, they only immersed themselves in the joy of harvesting, but they neglected the management of the fruit trees before they sprouted in the coming year. It is precisely this neglect that ruined the harvest of the coming year. After the apple tree has experienced a heavy result period, the “energy” in all aspects has been exhausted, and it needs to be supplemented in time. After harvesting in the autumn, organic fertilizer should be applied. Generally, it is appropriate when the leaf function has not been degraded and there is strong photosynthesis. At this time, nutrients return to the roots, which can promote root growth and root healing, and help increase the nutrient level of the tree. At the same time, combined with irrigation, supplemented with 0.3-0.5% urea sprayed with late autumn leaves to delay the senescence of the leaves and grow the leaves. The photosynthesis time increases the nutrient level of 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.
Apple tree winter shear is a very important part. Winter shear is mainly to adjust the skeleton structure of the tree body, balance the growth of various parts of the tree body, and regulate the relationship between vegetative growth and reproductive growth. At present, the most suitable tree shapes are: small crown sparse layer shape, free spindle shape, slender spindle shape, trunk cylindrical shape, etc. When trimming, it depends on the tree, focusing on the tree structure, the size of the branches is reasonable and evenly distributed. In order to make full use of light energy, to achieve high quality and high yield.
It is very important to irrigate the fruit trees in the early stage of germination. When the frozen soil layer is not opened before germination, irrigation can increase ground temperature, increase soil moisture, accelerate root growth, promote germination, and ensure flowering rate, especially in the north. At this time, it is a drought period, and irrigation is more important. . In addition, the top dressing is carried out before germination, and the quick-acting nitrogen fertilizer is mainly used, and the phosphate fertilizer can make the flowers of the apple tree tidy and improve the fruit setting rate.
