Abstract:
Taking cole as material,the effect of two different solubility polymeric slow/release fertilizer on quality and yield of vegetables were studied.The results showed that the solubility of 45% polymeric slow/release fertilizer could effectively improve the yield of cole,the solubility of 21% polymeric slow/release fertilizer was lower than ordinary chemical fertilizer.Besides,the high and low solubility polymeric slow/release fertilizer could effectively improve the quality of cole.Compared with ordinary fertilizer,the content of nitrate of cole treated with the polymeric slow/release fertilizer could decreased 3.0～4.8 times,and the content of vitamin C and soluble sugar increased significantly.
