Method for raising seedlings of tomatoes through grafting

Abstract

The invention relates to a method for raising seedlings of tomatoes through grafting. The method comprises the following steps: S1, selection of rootstocks; S2, preparation of a substrate; S3, cultivation of the rootstocks and scions: (1) determining a sowing date; (2) soaking seeds, and performing germination; and (3) performing sowing; S4, management after sowing is conducted: (1) performing rootstock management; and (2) performing scion management; S5, grafting: (1) performing preparation before grafting is conducted; and (2) determining a cutting grafting method; and S6, management after grafting is conducted: (1) performing heat preservation; (2) performing moisture preservation; (3) performing shading; (4) removing lateral buds; (5) performing management after survival is achieved; and (6) controlling diseases and pests. The method has the advantages that the grafting efficiency can be improved, the healing speed of wounds of the rootstocks and the scions is accelerated, and a high survival rate of the grafted seedlings, high disease resistance and good quality of the grafted seedling products are achieved; and the method is particularly suitable for tomato seedling graftingcultivation in scorching heat, high temperature, exposure to the sun and other harsh environments in summer.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for grafting tomato seedlings. Background technique [0002] Tomato is one of the vegetables that people love. In recent years, due to limited land resources, crop rotation has been blocked, and soil-borne diseases such as tomato bacterial wilt, fusarium wilt, and root rot have become increasingly serious, affecting the normal development of the tomato industry. Through grafting, tomato has the functions of disease resistance, heavy cropping resistance, and enhanced plant growth. It can effectively prevent the occurrence of soil-borne diseases such as tomato bacterial wilt, root rot, fusarium wilt, and root-knot nematode in continuous cropping fields. Absorptive capacity, increase tomato yield, tomato grafting and seedling cultivation have become the general trend. [0003] The traditional tomato grafting technique usually uses grafting clips to fix, insert the cut ...

AI Technical Summary

Problems solved by technology

However, this method is complicated to operate, requires high proficiency, slow speed, high labor cost, low benefit, and few grafted seedlings. In addition, when the grafting clip is fixed, it is easy to damage the stems of the grafted rootstock and scion, affecting healing and the later stage of grafted seedlings. Cultivate and grow, and take up a lot of space, it is not suitable for large-scale seedling cultivation and long-distance transportation, and the market competitiveness is weak

[0004] In addition, the current grafted tomato seedlings still have problems such as uneven size of grafted seedlings, low uniformity, and insufficient seedlings, which increases the difficulty of field management after grafted seedlings are planted, and the fruit yield is low and the marketing period is inconsistent.
