| 摘 要： | 设不施氮、施普通尿素、施控释尿素80％、施控释尿素60％4个处理,研究控释尿素对鸭梨产量、品质和土壤氮素的影响.结果表明:与100％普通尿素比较,控释尿素的用氮量为普通尿素的80％,0～30 cm土壤的碱解氮与硝态氮的含量及梨果的产量显著增加.用氮量60％,与普通尿素的接近.控释尿素处理的梨果品质、氮肥利用率显著提高,且以用氮量60％的肥效最佳.

| Abstract: | Set 4 treatments that were CK,ordinary urea,80% and 60% controlled released urea,studied the controlled release fertilizer effect on tne yield,quality of pears and N in soils.The results showed that compared with 100% ordinary urea,the use of nitrogen release urea for ordinary urea 80%,content of alkali-hydro nitrogen and the nitrate in 0~30 cm soil,the yield increased significantly.Use of nitrogen 60% controlled release urea was close to 100% ordinary urea.Compared with ordinary urea,controlled released ur... |
