摘要
以小油菜为试材,研究了高低2种不同溶解度的高分子缓/控释肥对盆栽小油菜品质及产量的影响。结果表明：25℃下溶解度为45%的高分子缓/控释肥能够有效提高小油菜产量,溶解度为21%的高分子肥效果不如普通化学肥料;高溶解度和低溶解度的高分子缓/控释肥可有效提高小油菜品质,较普通肥相比可降低硝酸盐含量3.0~4.8倍,提高维生素C和可溶性糖含量作用显著。
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 3.0~4.8times,and the content of vitamin C and soluble sugar increased significantly.
