Potato seed dormancy extension agent of potatoes and using method thereof

Abstract

The invention provides a potato seed dormancy extension agent of potatoes. The potato seed dormancy extension agent comprises camphor balls of which the mass content is not less than 20%; the potato seed dormancy extension agent of the potatoes aims at solving the problem of time difference of a harvest season and a planting season of the potatoes by prolonging the dormancy of the potato seed and inhibiting sprouting of the potato seed, so as to form synchronism of the germinating time and the planting time of the potato seed and reduce the rotten potato rate (attrition rate) caused by early germination of the potato seed. Meanwhile, the potato seed of the potato can be stored at normal temperature by the potato seed dormancy extension agent; the use of cold storage facilities and related energy consumption in the storage process of the potato seed is reduced; the cost of the storage process of the potato seed is also reduced.

Description

technical field [0001] The invention relates to the technical field of potato seeds, in particular to a seed potato dormancy prolonging agent and a method for using the same. Background technique [0002] The dormant period of potato seed is 45 days to 90 days. The time difference between the planting season and the harvest season of potatoes in most areas of my country is too far, that is to say, the time from harvest to planting is far beyond its dormant period. If the dormancy period of potato seed is not extended, it cannot be guaranteed that it will maintain vigor and optimal planting state when planted. Therefore, it is very necessary to control the dormancy period of seed potatoes during seed potato storage. [0003] At present, in southern my country, hormones, such as paclobutrazol, chlorphenamine, methyl naphthalene acetate, etc., are generally used to prolong the dormant period of potato seed potatoes in combination with low-temperature cold storage storage, whi...

AI Technical Summary

Problems solved by technology

Among these two storage methods, the former has defects such as complicated operation, high energy consumption, high cost of infrastructure and equipment, and the influence of hormones on seed potatoes; the latter has a high rate of rotten potatoes, and can hardly extend the dormant period of seed potatoes. Potatoes must be planted after the dormant period, that is, the planting season is single, and seed potatoes cannot meet the needs of multi-season planting
