Description

technical field

[0001] The invention relates to a grafting technique, in particular to a method for indoor grafting of improved walnut varieties in winter. Background technique

[0002] Walnut is one of the dry fruit tree species with rich germplasm resources. The current walnut cultivation is mainly based on seed propagation. The existing fruit trees are mainly walnut seed trees. The yield of walnut is low, the quality of fruit varies, and the commodity value is low.

[0003] In the prior art, the walnut vegetative propagation technique is mainly applied to outdoor budding and grafting techniques to accelerate the scale propagation speed of fine walnut varieties.

[0004] There are at least the following disadvantages in the above-mentioned prior art: it is highly affected by seasons and the survival rate is low. Contents of the invention

[0005] The purpose of the present invention is to provide a method for indoor grafting of improved walnut varieties in winter which ...
