Tomato grafting seedling growing management method

Abstract

The invention discloses a tomato grafting seedling growing management method, and belongs to the technical field of crop cultivation. The tomato grafting seedling growing management method comprises the following steps of medium preparation, stock and scion preparation, grafting and grafting seedling management. According to the method, when tomatoes are subjected to grafting, a soft casing pipe is utilized instead of a grafting clamp, the operation is simple, the tomato grafting seedlings can be prevented from being harmed by tomato grafting seedlings, and the survival rate is increased. A seedling growing goods shelf with light supplementing and moving functions can greatly increase the vertical and improve the seedling growing efficiency of the unit area; a plastic thin film is adoptedfor covering, the watering amount in the early stage can be reduced, heat and vapor released by respiration of the tomato grafting seedlings are utilized, and artificial jamming is reduced; non-wovenfabric is utilized for coverage, the moisture preservation can be added, the ventilation function is also achieved, and the situation that seedlings are rotted when the humidity is too large is avoided; in the early using period, weak light is adopted for light supplementing, the healing rate is increased, tomato grafting seedlings grow more robustly, the disease resistance is stronger, the overall growth of the grafting seedlings is more uniform and neater, and guarantee is provided for field planting in the later period.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a management method for tomato grafting and seedling cultivation. Background technique [0002] Tomato is one of the main solanaceous vegetables cultivated over winter in southern Zhejiang. It has a large production area and has exceeded 50,000 mu, becoming the main source of farmers' income. With the continuous expansion of the tomato planting area and the high multiple cropping index, the obstacle of tomato continuous cropping is very prominent, and soil-borne diseases such as bacterial wilt are becoming more and more serious, causing a large area of ​​tomato production to die in the planting base, causing heavy losses to vegetable production and farmers. has become a major bottleneck in facility tomato production. Grafting, as an effective method to effectively overcome the soil-borne diseases caused by continuous cropping of tomato, has been widely used in ...

Problems solved by technology

However, in this patent, the selected rootstock and scion were not sterilized, and the grafted parts were corrupted and dead seedlings, which affected the survival rate of grafted seedlings. At the same time, in the post-management of grafted seedlings, the ventilation time in the first three days was relatively short, which could not effectively guarantee the benefits of grafting. Seedling growth environment

[0007] Chinese patent CN107896673A discloses a tomato grafting method, including the following steps: (1) selection of rootstock: should select a tomato rootstock with comprehensive resistance; (2) selection of scion varieties: tomato varieties according to conditions such as seasons and climates of cultivation; (3) Grafting material: the grafting needle is a steel needle with a length of 10mm and a diameter of 0.2mm; (4) Breeding: sow the scion and rootstock at the same time, and use the matrix plug for seedling cultivation; (5) Grafting: choose the rootstock and scion with the same thickness when grafting For seedlings, first use a blade to cut obliquely upward on the rootstock, remove the upper part, and then use a grafting needle to insert the grafting needle along the axis in the center of the cutting surface of the rootstock; use the same method to cut the scion downward obliquely, and insert the cut scion on the rootstock (6) Management after grafting: supply water from the bottom after the seedlings have been grafted, place them in a small arched shed after absorbing enough water, and keep the shed to keep moisture. The growth status of tomato seedlings is greatly affected, which is not conducive to their vigorous growth

However, in this invention, in the post-grafting management method, proper light and wind protection were not carried out in the first three days, which would easily cause serious dead seedlings, affect the survival rate, and reduce the efficiency of grafting
