Double-broken-root double-stem tomato grafting method

Abstract

The invention discloses a double-broken-root double-stem tomato grafting method. The double-broken-root double-stem tomato grafting method comprises the following steps of S1, enabling stocks to havebroken roots and anew take roots: enabling stock seedlings to have broken roots when having two leaves and one bud to three leaves and one bud, and performing cuttage into substrates so that the stockseedlings having broken roots to anew take roots; S2, promoting double-end scions uniform: topping off scion seedlings having two leaves and one bud to three leaves and one bud so that two growing points anew begin to grow at positions of cotyledons, and after topping off the scion seedlings, performing intervention of promoting double stems and promoting double stems uniform in the specific steps of when new growing points begin to grow, using balanced type fertilizers once, and then supplementing fertilizers once every three days so as to promote double stems to grow uniformly; S3, performing step S1 and step S2 at the same time, and after 8-12 days, removing unqualified stocks and scions; and S4, grafting qualified stocks and scions. The grafting process of double-end seedlings is divided into three nodes, and flow standardization management is performed, so that the survival rate of grafted seedlings is 80% or above, the cost can be saved by 25%, and the tomato yield can be increased.

Description

technical field [0001] The invention relates to the field of vegetable seedling cultivation, in particular to a method for grafting tomato with double cut roots and double stems. Background technique [0002] Tomato fruit is rich in nutrition and has a special flavor. Can be eaten raw, cooked, processed tomato paste, juice or whole fruit canned. Tomato grafted seedlings have the advantages of vigorous plant growth, strong photosynthetic ability, strong stress resistance, and high yield, and are widely used in facility tomato cultivation. [0003] Double stem seedling grafting is in research, and for example patent name is " a kind of double stem grafting method of tomato seedling and its application ", and publication number is " CN110402708A ", adopts two scion grafts to realize double stem seedling on a stock, but The first of this kind mode is that scion consumption is more, and the 2nd, rootstock wound is many, and survival rate is not high. [0004] Another thing is ...

Problems solved by technology

[0003] Double stem seedling grafting is in research, and for example patent name is " a kind of double stem grafting method of tomato seedling and its application ", and publication number is " CN110402708A ", adopts two scion grafts to realize double stem seedling on a stock, but The first method of this method is that the amount of scion is more, and the second is that the rootstock has many wounds and the survival rate is not high.

[0004] Another thing is to directly use one seedling and two stems for grafting, but in the grafting process, due to the uneven growth of the double stems, the success rate of grafting is low, and the management of grafted seedlings after grafting is complicated and the management cost is high; the success rate of grafting is low in around 35%
