Abstract:
In order to verify influence of Potash on yield and quality of stem tumorous mustard,set up the six different amount treatment of applying potash.By fields trials and lab analyses.The result indicates that:The more the amount of applying potash is,the more the amount of creature on the ground of stem tumorous mustard is,the ratio of stem/leaf is raised,the yield of tumorous stem is raised,the maximum amount can be raised by 80.4%.At the same time,applying potash can reduce content of skin of vegetable(4.6%) to a certain extent,improve index of vegetable shapes of tumorous stem(1.09),raise processing quality and commodity.Content of soluble carbohydrate and content of crude protein between the amount of applying potash exists obvious harmonization.Content of VC and the amount of applying potash exists obvious relation.The maximum content of soluble carbohydrate can be raised by 47.7%,and content of crude protein by more than 10%,and content of VC by 3.9%.The amount of applying Potash(K2O)in production is within 13 kg/667m2,can obtain higher yield and better quality.
