| 摘 要： | 针对目前农民施肥中存在的施肥量大、施肥次数多等问题,在黑龙江省不同区域进行白浆土水稻不同施肥方式试验。结果表明:不同施肥处理对白浆土水稻生长发育有显著影响。100%控释尿素一次性基施(处理5)和100%普通尿素一次性基施(处理3)水稻产量相差不多。与处理5相比,处理4、处理1和处理2水稻产量分别增加1 257、9607、89 kg.hm-2,增幅在10.3%~16.4%;净产值分别增加2 8732、3871、864元.hm-2。综合考虑到水田管理方便、省时、省力的情况下,以50%尿素和50%控释尿素混合一次性基施(处理4)效果较好。

| Abstract: | Different plot experiments about applied nitrogen amount,time and proportion were carried out at different fertility area in Heilongjiang Province to resolve much and frequently applied nitrogen fertilizer.The results showed that nitrogen fertilizer have a significant impact on rice growth and development.Rice yield was similar between 100% controlled release urea and 100% urea in one-time applying fertilization.Compared with the treatment 5,Rice yield of treatment 4,treatment 1 and treatment 2 was increased by 1 257,960 and 789 kg·hm-2,increased yield range of 10.3%-16.4%;net output increased by 2 873,2 387 and 1 864 yuan·hm-2.Rice yield and profit were better with 50% urea and 50% controlled release urea one-time application（Treatment 4）which could save time and effort,make management convenience for paddy field. |
