| 摘 要： | 为了探讨控释尿素和普通尿素混施的最佳比例,以施用常规尿素为对照,设5个处理,研究控释尿素和普通尿素混施对土壤氮含量及大豆产量和品质的影响。结果表明:控释尿素和普通尿素配施能够提高土壤碱解氮含量和全氮含量,在整个生育时期碱解氮呈下降趋势,土壤全氮呈上升趋势。控释尿素不同比例的施用,提高大豆不同生育期的生物量,R4到R8时期提高最明显,以控释尿素100%(T5)处理提高最大。大豆蛋白质上升,脂肪下降,蛋脂总量提高,改善品质。5个处理中,以控释尿素占50%(T3)产量最高,达到3019.88kg/hm2。与常规施肥(T1)相比提高11.33%,差异达到显著水平。

| Abstract: | For the purpose of optimum proportion of controlled-release urea（CRU） and common urea（CU） combined application,conventional applying urea as control,let five treatments,a study on the effect of CRU and CU combined application on soil nitrogen content and yield and quality of soybean.The results indicated that,CRU and CU combined application could promote soil available nitrogen and soil total nitrogen contents,soil available nitrogen contents showed a rising tendency and soil total nitrogen contents decreasing.Different proportion application of the CRU,aboveground biomass of soybean in different growth stages,especially R 4 to R 8,the most raising in T 5.The protein increased and fat decreased,and improved soybean quality.The treatment of T 3 had the highest yield,reached 3019.88 kg/hm 2,increased yield by 11.33% compared with common urea application,the difference reached significant level. |
