摘  要:
采用田间试验研究了硫黄加树脂包膜尿素(SPCU)、树脂包膜尿素(PCU)在玉米上的施用效果。结果表明:氮素同等用量时控释尿素增产效果显著,分别比相对应的等氮量普通尿素(PU100%)增产7.3%、5.9%,N用量减少30%的SPCU70%、PCU70%处理产量分别比相对应的等氮量普通尿素(PU70%处理)增产10.2%、9.1%;控释尿素氮素用量比普通尿素氮素用量减少30%,不影响夏玉米产量。

摘  要:
Based on the field test,the effects of SPCU and PCU on summer corn are studied.The results show that: in the same N nutrient conditions,the applying effect of controlled-release urea is significant,it increases 7.3% and 5.9% compared with the 100% conventional urea test(PU 100%),the yields of corn for SPCU 70% and PCU 70% are increased 10.2% and 9.1% compared with the 70% conventional urea test(PU 70%).Compared with conventional urea,controlled-release urea is decreased by 30%,however the yield is same.
