Method for cultivating walnut seedling with container in greenhouse

Abstract

The invention discloses a method for cultivating a walnut seedling with a container in a greenhouse. The method comprises the steps that a young seedling serves as a stock and a current-year newly-grown un-lignified fine walnut variety branch serves as a scion, so that grafting is conducted; the grafted walnut seedling is placed in a nutrition bowl for cultivation; the walnut seedling cultivated in the nutrition bowl is placed in the greenhouse to grow. According to the method, the high physiological activity of immature stem cells of plants is utilized ingeniously, the young seedling is used as the stock and the current-year newly-grown un-lignified fine walnut variety branch is used as the scion, the healing capacity of the walnut seedling is high, growing is rapid, and the survival rate is high; the light matrix non-woven fabric nutrition bowl is adopted for cultivation, afforestation at all seasons is facilitated, and the survival rate of afforestation is increased; the optimal temperature and humidity required by the grafted walnut seedling can be regulated manually in the greenhouse, and the problem existing in field planting that the survival rate can be affected by severe bleeding of the grafted seedling or over-low temperature due to continuous raining is avoided.

Description

technical field [0001] The invention relates to a method for cultivating walnut seedlings, in particular to a method for cultivating walnut seedlings using containers in a greenhouse. Background technique [0002] At present, it is well known that walnut seedling cultivation is carried out outdoors. In the first year, land requisition, land preparation, sowing and fertilization, etc. are managed to make it grow vigorously. In the second year, the stubble can be grafted. The whole process takes two years. The management is difficult, the management fee is high, and it is affected by the natural environment. As a result, the survival rate is not high, and it cannot be managed according to the normal growth of seedlings. When walnut saplings are grafted because the rootstock is too aging, it cannot heal with the tender scion, resulting in a low graft survival rate. Grafted live seedlings lost too much fertile soil during the transplanting process, and the roots were damaged, ...

AI Technical Summary

Problems solved by technology

In the first year, land requisition, land preparation, sowing and fertilization, etc. are managed first to make them grow vigorously. In the second year, the stubble can be grafted. The whole process takes two years. The management is difficult, the management fee is high, and it is affected by the natural environment. As a result, the survival rate is not high, and it cannot be managed according to the normal growth of seedlings

When walnut saplings are grafted, the rootstock is too old to heal with the young scion, resulting in a low graft survival rate

During the transplanting process, the grafted live seedlings lost too much fertile soil and the roots were damaged, resulting in a low survival rate of afforestation
