摘要:
按尿素种类和施肥量共设6个处理，研究控释尿素和普通尿素混施对大豆农艺性状及产量和品质的影响。结果表明：控释尿素和普通尿素混施能够提高大豆不同生育期的株高和干物质积累量，且T6（控释尿素100%）提高最多。从R2到R6时期，叶绿素含量逐渐增加，R4和R2期施肥各处理与对照相比差异达到显著水平，处理T4（控释尿素50%+常规尿素50%）叶绿素值最高，但各施肥处理间差异不显著；叶面积指数（LAI）值先增大后减小，R4时期最大，施肥处理LAI显著高于不施肥对照，且以处理T4最佳。控释尿素和普通尿素混施极显著提高了大豆的产量，且以T4处理产量最高。控释尿素不同比例混施能够提高蛋白质含量，降低脂肪含量，并使蛋脂总量增加。综合试验结果可知，控释尿素50%+常规尿素50%为最佳混施比例。
Abstract:
In this paper,six treatments with different kinds of urea and fertilizer rates were used to clarify the effect of controlled-release urea(CRU)blended with common urea(CU)on agronomic characteristics,yield and quality of soybean(Glycine max).The results showed that CRU blended with CU could promote soybean plant height and soybean dried biomass in different growth stages and the promotion of T6 treatment(CRU 100%)was the highest among all treatments.From R2 to R6 stage,the chlorophyll content increased gradually and LAI increased firstly and then decreased and reached peak at the R4 stage.The chlorophyll content,LAI and yield of fertilizer treatments were significantly higher than control and T4 treatment(CRU50%+CU50%)was the highest among all fertilizer treatments.Meanwhile the blended fertilizer could improve total content of protein and fat.Through comprehensive analysis,CRU50%+CU50% was the best blending ratio.
