Description

TECHNICAL FIELD

[0001] The present application relates to the mountain persimmon planting technical field. BACKGROUND

[0002] The mountain persimmon is generally planted by the grafted seedlings cultivated in the nursery. When transplanting, the grafted seedlings are cut to 30-40 cm to promote the growth of lateral roots and fibrous roots, thereby improving the survival rate of the grafted seedlings. However, the grafted seedlings have the following problems after transplanting: the main roots cannot penetrate into the soil to absorb water and nutrients, and the grafted seedlings are completely dependent on surface water, which are not drought-resistant and wind-resistant. If the 1-2 year old seedlings are directly cultivated in the original place, the main roots are as long as 1.0 meter or more, which have the advantages of drought and wind resistance compared with the grafted seedlings. However, the seedlings have the following disadvantages: low variety purity, easy to appear variety, long growth cycle, high labor input, and are not suitable for mountain persimmon planting. Therefore, it is necessary to improve the existing persimmon planting method so that it can be used for mountain persimmon planting, and can ensure the survival rate of persimmon planting and improve the wind and drought resistance of persimmon.
