Method for cultivating tidy and strong gourd stock seedlings

Abstract

The invention discloses a method for cultivating tidy and strong gourd stock seedlings. The method comprises eight steps of seed drying, seed soaking, seed airing, germination acceleration, sowing, uncapping, cup picking and disease and insect prevention. Through seed drying, seed airing and prolonging the seed soaking time, the problems of slow germination and untidiness of gourd seeds due to moisture absorption difficulty because of thicker seed coats of gourd seeds, inhibition of seed germination by mucus on seed coats of gourd and the other factors are solved; and the seeds are treated with a multi-effect triazole solution during seed soaking, elongation of hypocotyls of gourd seedlings is effectively inhibited, and sowing depth and direction, timely uncapping and cup picking are combined to ensure that stock seedlings are tidy and consistent during grafting. The method is simple, easy to operate, broad in market prospects and suitable for wide application.

Description

technical field [0001] The invention relates to a method for cultivating rootstock seedlings, in particular to a method for cultivating neat and robust gourd rootstock seedlings. Background technique [0002] Using gourds as rootstocks to cultivate watermelon grafted seedlings is one of the most effective methods for controlling Fusarium wilt in watermelon production. Fusarium wilt of watermelon is a devastating soil-borne disease. The pathogen can survive in the soil for 5 to 6 years. Continuous cropping often causes severe disease, resulting in reduced yield or even failure. Cucurbit not only has a strong resistance to the pathogen of Fusarium wilt of melons It is resistant to watermelon and has a strong affinity with watermelon. It has almost no effect on the quality of watermelon after being grafted with watermelon as a rootstock. It is currently the most commonly used rootstock variety for cultivating watermelon grafted seedlings. [0003] However, in the cultivation p...

AI Technical Summary

Problems solved by technology

Watermelon grafted seedlings must be raised in protective facilities such as greenhouses. Due to the influence of the microclimate in the greenhouse, after the emergence of gourds, the hypocotyls are prone to rapid elongation, forming "tall seedlings". The hypocotyls are thin and long, resulting in The contact area of ​​the grafting interface is small, which is not conducive to the grafting operation, but also affects the survival rate of the grafting. At the same time, the hypocotyl is too long, and the seedlings are prone to lodging, especially after watering, which brings great difficulties to the later management.

[0006] (3) The cotyledons of the gourd seedlings are not in the same direction. During the grafting operation, the posture must be changed continuously, which not only affects the grafting speed, but also easily touches the grafted watermelon scion, causing the scion to break or fall

[0007] (4) Due to the inconsistency of seed maturity and sowing depth, the gourd seeds will not emerge uniformly after sowing, the seed shell will not fall off (commonly known as "capped"), and the growth will be different. When grafting, the gourd seedlings will vary in size, and some are suitable for grafting. , and some are too small to be grafted, and even some empty cups that have not emerged, and small and weak seedlings that are harmed by diseases and insect pests cannot be grafted

[0011] However, the above-mentioned technologies only solve a single problem, but cannot solve all problems at the same time.
