Problems solved by technology

[0002] At present, tomatoes are generally planted in autumn in the southeast coast of Fujian, and seedlings are generally raised during the high temperature season from July to August. During this period, temperature-controlled seedling sheds are required for grafting, and temperature-controlled seedling sheds require a large investment, and the number of seedlings is limited. It is relatively concentrated, and the seedling age requirement for grafted tomato seedlings is relatively strict. Generally, it is more suitable to transplant about 20 days after grafting. If the seedling age is too short, the survival rate after transplanting is low, and if the seedling age is too long, it is easy to grow excessively.
Due to the short elasticity of seedling age and the concentrated planting time in the southeast coast, the utilization rate of seedling sheds is low, and the number of seedlings is limited, which cannot meet the needs of growers

Abstract

The invention prelates to a seedling culture method capable of increasing a tomato grafting survival rate. The seedling culture method is characterized by including the steps of seedling culture substrate preparation, scion selection and culture, stock selection and culture, grafting, post-grafting management, seedling management and filed planting, wherein stock selection and culture includes spraying 150 PPM paclobutrazol on stocks after 20-25 days of stock seeding; or post-grafting management includes spraying 150 PPM paclobutrazol on grafted seedlings after 13-15 days of grafting. The seedling culture method has the advantages that the grafting survival rate can be increased, grafted nursery stocks are thick with thick leaves and high in quality, and the seedling age elasticity is changed from 5 days to about 15 days and is increased by about 10 days, so that the number of the seedlings is increased, and the utilization rate of a seedling culture greenhouse and the survival rate after transplanting are increased.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a seedling raising method for improving the survival rate of tomato grafting. Background technique [0002] At present, tomatoes are generally planted in autumn in the southeast coast of Fujian, and seedlings are generally raised during the high temperature season from July to August. During this period, temperature-controlled seedling sheds are required for grafting, and temperature-controlled seedling sheds require a large investment, and the number of seedlings is limited. It is relatively concentrated, and the seedling age required for grafted tomato seedlings is relatively strict. Generally, it is more appropriate to transplant about 20 days after grafting. Due to the short elasticity of seedling age and the concentrated planting time in the southeast coast, the utilization rate of seedling sheds is low, and the number of seedlings is limited, which cannot meet the needs...
