Method for improving vital indexes of gourd seeds

Abstract

The invention discloses a method for improving vital indexes of gourd seeds, sequentially comprising the following steps: 1) soaking the gourd seeds in water at the temperature of 55-60 DEG C for 10-15m under the stirring condition; 2) soaking the gourd seeds obtained in step 1) in water at a constant temperature of 25-27 DEG C for 6-10h, drying the seeds in the air and then carrying out soaking at the constant temperature and drying in the air on the gourd seeds once again; and 3) soaking the gourd seeds obtained in step 2) in water at a constant temperature of 25-27 DEG C for 6-8h, and then placing the seeds in a thermotank for germinating. By adopting the method of the invention, the vital indexes of the gourd seeds can be effectively improved.

Description

technical field [0001] The invention relates to a method for improving the vigor index of seeds, in particular to a method for improving the vigor index of gourd seeds. Background technique [0002] The scientific name of gourd is gourd [scientific name Laqenaria siceraria (Molina) standl], which is an annual climbing herb of Cucurbitaceae Cucurbitaceae. In recent years, with the continuous expansion of watermelon area and the harm of Fusarium wilt, grafted watermelon has become more and more popular among melon farmers, and the cultivation area has increased year by year. Grafted seedling rootstocks can not only prevent the occurrence of Fusarium wilt, but also have strong root absorption and fertility. The amount of fertilization of grafted gourd seedlings can be reduced by 20%-30% compared with self-rooting watermelon, so that the crops can be stable and high-yield, especially the grafting can greatly reduce the amount of pesticides, which is conducive to the development ...

AI Technical Summary

Problems solved by technology

[0005] This method is not only cumbersome to operate, but also makes it very difficult to accelerate the germination of the seeds, resulting in a low germination rate, and the overall performance of the germination potential, germination index and vigor index of the seeds is weak, which will increase the cost of seedling cultivation and is time-consuming and laborious.
