Cauliflower grafting method

Abstract

The invention relates to a cauliflower grafting and seed reserving method. The cauliflower grafting and seed reserving method comprises steps that, seedling growing of cabbage mustard is carried out in early September, seedlings are grown in a greenhouse at standard plant distances of 45-55cm at the end of September or the beginning of October, and topping is carried out when height of the cabbage mustard is in a range of 30-40cm; cauliflower for seed reservation is cultivated 0.5-2 months before seedling growing of the cabbage mustard, and grafting is carried out when flower balls of the cauliflower start loose and branches stretch; 2-5 side branches of each stock are reserved for grafting; after grafting, the grafted plants are arranged in an external arched shed, proper shading is carried out, the top portion of the arched shed and periphery are sprayed, and humidity is maintained to be in a range of 90-100%; disease infection caused by overhigh temperature is prevented, 800-time chlorothalonil and streptomycin solution is sprayed one time a day in first three days of the arched shed; daytime temperature is maintained to be in a range of 20-25 DEG C, night temperature is maintained to be in a range of 15-20 DEG C, ventilation and light transmission gradually increase after three days, and plant grafting is carried out in 6-10 days to acquire living plants. Through the method, seed reservation is easy, and minimum cost is realized.

Description

technical field [0001] The invention relates to the technical field of cauliflower seed saving, in particular to a method for cauliflower grafting and seed saving. Background technique [0002] Cauliflower, also known as cauliflower, cauliflower or cauliflower, is a cruciferous vegetable, a variant of cabbage, and belongs to annual vegetables. The product organs of cauliflower are curds formed by the aggregation of shortened flower branches, flower rachis, and flower buds. Cut the bulbs and thin the branches, and bloom and pollinate the seeds in March to April of the second year. [0003] The lowest temperature in winter in the middle and lower reaches of the Yangtze River is below 0°C. Cauliflower bulbs have strict temperature requirements during the formation period. When the temperature is below 5°C, the bulbs will suffer from cold damage. When the cauliflower is selected to save seeds, the number of plants planted in the seed selection nursery is often very large, and ...

AI Technical Summary

Problems solved by technology

When the cauliflower is selected to be reserved, the number of plants planted in the selection nursery is often very large, and the selected excellent single plants to be reserved are few. The cauliflower plants need to be transplanted to the greenhouse for overwintering, but after the cauliflower grows curds, transplant The survival rate of planting is low. If the seeds are directly planted in the greenhouse, the utilization rate of the greenhouse is very low and the cost is high

[0004] On the other hand, the humidity in the greenhouse is high, and the wounds caused by repeated cutting and thinning of cauliflower are large. The curds are prone to disease and rot, and the seed yield is often low. Even the selected excellent individual plants cannot retain seeds, which affects the entire plant. The progress of the breeding work
