In recent years, because the confinement of orchards is not conducive to mechanical operations, the aging of orchard workers, and the fertilization and spreading of fertilizers such as fertilization have led to a reduction in the depth of tillage soil cultivation, gradual shallowing of the tillage layer, increased thickness of the plough bottom layer, and acidification of the soil. It impedes the infiltration of soil moisture, impairs the ability of the soil to store water, retain water, and supply water, and it is also not conducive to the growth of roots. The tree vigor of fruit trees is seriously affected. Therefore, it is particularly important for the orchard to make profound changes in the soil. According to tests, about 1/4 of the soil in each fruit tree is good to ensure the normal growth of the fruit tree. Therefore, it is advisable to combine the autumnal basal fertilization with 1/4 or so tree trays each year for fertilization, and 4 to 5 years for the complete deep turning of orchard soil to ensure the continuous growth of fruit trees. The deep turning of the orchard in the orchard should be avoided when there is a lot of drought and rain, otherwise it will be detrimental to the restoration and growth of the fruit tree roots.
