摘要
在黑龙江省中部黑土区对控释肥在大豆生产上的应用效果进行了研究,结果表明:控释尿素与普通尿素搭配施用,与等养分普通复合肥比较,可使大豆增产20.1%～27.0%,搭配比例以控释尿素占总氮量的50%～70%为好,可满足大豆生育期氮素的营养;控释大豆专用BB肥比等养分普通复合肥增产26.1%。
The application of control released fertilizers in soybean production for black soil area in central part of Heilongjiang was investigated. The restdts showed that, compared to the composite fertilizers with equal nutrient, control released urea fertilizer incorporated with ordinary urea increased soybean yield by 20.1% 27.0% With the control released N accounting for 50% to 70% of the total N, soybean N requirements will be met. and compared to nutrient in general ordinary compound, soybean-specific controlled release fertilizer BB increased yield by 26.1%.
