Method for preventing sorghum ear bagging mildewing

Abstract

The invention discloses a method for preventing sorghum ear bagging mildewing. The method includes the step that at the time after nine of one fine day before sorghum blooms, bagging is carried out through transparent sulfuric-acid paper bags. As bagging is carried out at the time point, ear mildewing commonly generated after the sorghum is bagged can be effectively prevented.

Description

technical field [0001] The invention discloses a method for preventing sorghum ear bagging from mold, which belongs to the technical field of sorghum bagging, and more specifically relates to a method for preventing sorghum ear bagging from mold. Background technique [0002] In the cross-breeding of sorghum, it is often necessary to bag the tassels of sorghum, and self-cross or hybridize sorghum on this basis. At present, the period of bagging selection is at the heading stage of sorghum, that is, bagging is done as soon as sorghum is heading. The selection of such bagging period is not a big problem in the northern regions of our country, but in the Jianghuai region, due to the relatively high air humidity, a large number of tassels are seriously moldy and deteriorated during the bagging process every year, and a large number of seeds are moldy and rotten. As a result, the seed viability and germination rate of bagged sorghum materials are reduced, which seriously affects...

Problems solved by technology

The selection of such bagging period is not a big problem in the northern region of our country, but in the Jianghuai region, due to the relatively high air humidity, a large number of tassels are seriously moldy and deteriorated during the bagging process every year, and a large number of seeds are moldy and rotten. As a result, the seed viability and germination rate of bagged sorghum materials will decrease, which will seriously affect the sowing and emergence of next year. The problem needs to be solved urgently
