Container nursery method for early-maturing high-yield navel oranges

Abstract

The invention discloses a container nursery method for early-maturing high-yield navel oranges. The container nursery method for early-maturing high-yield navel oranges comprises the following steps: preparation of nursery nutritional soil, rootstock transplanting, grafting and management after grafting. Because rootstock seedlings are cultivated in seedling containers, the whole seedling containers can be directly taken away during outplanting of nursery stocks, root damage of the nursery stocks cannot be caused, the nursery stocks have soil during outplanting, the navel oranges are suitable for being planted all year round, and are convenient to transplant and operate, meanwhile, during transplanting, only the seedling containers need to be removed, then seedlings are directly placed in nursery lines, soil does not need to be tramped by persons with feet, the roots of the nursery stocks cannot be damaged, the survival rate of the nursery stocks is high, after being transplanted, the nursery stocks directly grow in soil of an original growing place, a rejuvenation period does not exist after the nursery stocks are transplanted, the growth period of the navel oranges is greatly shortened, and therefore, the navel oranges can enter a fruiting period 2-3 years earlier.

Description

Technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a container seedling method for navel orange with early maturity and high yield. Background technique [0002] The existing cultivation methods of navel oranges are mostly open field planting. Open field seedlings are transplanted without soil. The seedlings are small and the root system is underdeveloped. When the roots are in direct contact with the soil when they come out of the nursery, the roots are likely to be damaged during excavation. Only a small amount of original soil can be brought, so that the transplanting of bare root seedlings can only be carried out in spring, and cannot be transplanted all the year round, and it will cause inconvenience to the transplanting operation. At the same time, the roots must be covered with soil when transplanting, which is undoubtedly Once the roots are damaged, and the seedlings do not grow on the soil of the original growing ...

Problems solved by technology

[0002] Most of the existing navel orange cultivation methods are open-field planting. The open-field seedlings are transplanted without soil, the seedlings are small, and the root system is underdeveloped. When the roots are in direct contact with the soil when they are out of the nursery, they are easy to cause damage to the roots when they are unearthed. Only a small amount of original soil can be brought, so that the transplantation of bare-root seedlings can only be carried out in spring, which cannot be transplanted all year round, and brings inconvenience to the transplanting operation; The roots are damaged once, and the seedlings do not grow on the soil of the original place after transplantation, so that the seedlings in the open field have a longer slow seedling period after transplantation, and the survival rate is relatively low
