摘　　要：以番茄为试材,与番茄专用肥及有机-无机复混肥对比,系统研究了两种不同溶解度的生物降解高分子缓控释肥对盆栽番茄生理特性、果实品质及产量的影响。结果表明:不同种类的生物降解高分子缓控释肥可以不同程度地提高番茄叶片叶绿素含量、叶片硝酸还原酶活性以及根系活力;生物降解高分子缓控释肥不仅对番茄的品质有明显的改善作用,而且还可以提高番茄的产量,生物降解高分子缓控释氮磷钾肥和生物降解高分子缓控释微肥效果可以分别增产75.39%和64.72%。Taking tomato as material, compared with common compound fertilizer and organ-inorganic compound fertilizer, the effects of two kinds of biodegradable slow and controlled-release polymeric fertilizer with different solubility on physiological characteristics, quality of vegetables and yield were studied. Results showed that different kinds of biodegradable slow and controlled-release polymeric fertilizer could improve tomato leaf chlorophyll content, root activity and nitrate reductase activity. And they could not only improve the quality of fruit, but also promote the yield of tomato, in the treatments of biodegradable slow and controlled-release polymeric NPK fertilizer and biodegradable slow and controlled-release polymeric micronutrient fertilizer, yield increased by 75.39% and 64.72%, respectively.
