Tomato seedling grafting technology and management method thereof

Abstract

The invention discloses a tomato seedling grafting technology and a management method thereof and belongs to the technical field of crop cultivation. The tomato seedling grafting technology comprises the following steps of: setting a seedling growing green house, selecting seedling substrate, selecting stock, carrying out pretreatment on seeds and sowing, grafting according to operating procedure and managing after grafting. The tomato grafting seedlings provided by the invention adopt 'Qieza No.2' as the stock, so that the seedlings have good disease resistance, and early germination potential is strong; besides, stem of eggplant stock is thick, so that survival rate of grafted seedlings can be beneficially improved; meanwhile, an approach grafting technology and a late optimized and reasonable management method are combined, so that the survival rate is further improved in a practical grafting process, growth vigour of the tomato seedlings after grafting is strong, late fruit setting time is ahead of schedule, fruit yield is high, pulp colour is pure, taste quality is good, and commodity performance is extremely high.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a tomato seedling grafting technique and a management method thereof. Background technique [0002] In recent years, tomatoes have been planted in large areas in greenhouses and open fields; tomato is a non-continuous crop, and it is difficult to achieve reasonable crop rotation. However, in the case of continuous cropping, the occurrence of tomato bacterial wilt is particularly serious, and soil-borne diseases are the main obstacles in production. Especially under protected cultivation conditions, soil-borne diseases are aggravated, affecting the normal growth of tomato plants, resulting in Yield reduction and quality decline, even no harvest, thus hindering the development of tomato industry. Studies have shown that the culprit of soil-borne diseases is the pathogenic bacteria hiding in the soil cultivation layer. They are distributed in different parts of...

AI Technical Summary

Problems solved by technology

[0007] Based on the above-mentioned reports on a large number of tomato grafting patent documents, it is shown that although the grafting of tomato seedlings has good effects in terms of disease resistance, yield and survival rate, it cannot provide guarantee for the quality of tomatoes in the later stage, thus hiding There are many problems, such as the color change of tomatoes is very slow after ripening, and even color and fruit appear; 2. The pulp taste of tomatoes after ripening is not as pure as that of original tomatoes; Moreover, there are problems such as low fruit setting rate, and grafted tomato has high requirements for grafting technology, environmental conditions and management measures. The grafting method in the current technology is also very unstable, and there are still problems such as weak growth of grafted tomato seedlings in actual production.
