Grafted seedling healing method and grafted seedling healing system

Abstract

The invention provides a grafted seedling healing method and a grafted seedling healing system, wherein grafted seedlings can be healed continuously without sunlight. The grafted seedling healing method comprises the following steps: first, constructing climate rooms which are adjustable in inner environment and are independent; and arranging a temperature adjusting device, a humidity adjusting device, a ventilation adjusting device and an illumination adjusting device in each climate room, wherein the illumination adjusting device is an LED plant lamp. The grafted seedlings are healed and cultured based on the grafted seedling healing method. The grafted seedling healing method has the advantages that the climate rooms which are adjustable in inner environment and are independent are arranged, so that the inner environments of the climate rooms can be adjusted according to growth characteristics of the grafted seedlings in different stages to achieve the optimum condition of healing and growth of wounds of the grafted seedlings, and therefore, the survival rate of the grafted seedlings is improved. As the illumination adjusting device is arranged to replace natural light to illuminate the grafted seedlings, the healing time of the grafted seedlings can be shortened, and the survival rate of the grafted seedlings is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting equipment, and more specifically relates to a healing method for grafted seedlings and a healing system for grafted seedlings. Background technique [0002] In facility agricultural production, continuous cropping obstacle is a syndrome. Continuous cropping will deteriorate the soil, and the types and numbers of pests and diseases in the soil will increase gradually, forming soil-borne diseases, resulting in weakened vegetable growth, reduced yield, reduced quality, and even extinction. Produce. Especially under the conditions of greenhouse vegetable cultivation, due to reasons such as continuous cropping and fertilization, the harm caused is more serious. Once it occurs, 20% to 30% of the plants will die in the light, and the whole field will be wiped out in severe cases. [0003] The best way to solve soil continuous cropping obstacles is to use grafted seedlings. The so-called ...

AI Technical Summary

Problems solved by technology

Manual grafting is time-consuming and labor-intensive, the productivity is very low, and it is difficult to guarantee the speed and quality

[0006] 2. The vegetable grafting operation is very technical, and the technicians who master the grafting technology are limited, which affects the wide promotion and application of the grafting technology

Although this method is simple and economical, it has the following disadvantages: it is difficult to control the environmental parameters, and the internal relative humidity and temperature are unbalanced, so the healing speed of the grafted seedlings is different, resulting in difficulties in the management of healing and later hardening; Natural light cannot be used in the early stage of healing, and it is difficult to ensure that it is affected by the weather when light is needed in the later stage, which seriously affects the healing speed; the arch shed occupies a large area and is not suitable for batch-scale healing of grafted seedlings
