控释肥施用对带状复合种植黑豆和谷子农艺性状及产量的影响
Effects of Controlled-release Fertilizer Application on Agronomic Characters and Yield in Strip Compound Cropping System of Black Soybean and Millet
摘要
Abstract
In order to select the high-efficiency fertilization mode in the belt compound planting,the effects of different fertilization modes on the agronomic characters and yield of black bean and millet in the belt compound planting were studied through the 3-year field experiment.In this study,four fertilization models were set up for black soybean and millet,respectively,including no nitrogen fertilizer(CK),conventional fertilization(CF),topdressing for controlled-release fertilizer(DN+/GN+),one-time basal application of controlled-release fertilizer(DN/GN).Low nitrogen controlled-release fertilizer was used for black soybean,and high nitrogen controlled release fertilizer was used for millet.The results showed that:(1)There was no significant difference in dry matter weight among treatments at seedling stage,and the dry matter weight of DN+/GN+ and DN/GN at other growth stages was significantly higher than that of CF and CK.There was no significant difference between DN+/GN+ and DN/GN.(2)At maturity,compared with CF,the dry weight of black soybean millet treated with DN/GN and DN+/GN+ increased by 3.53% ～11.76% and 14.10% ～30.42%,and the yield and its components of black soybean millet treated with DN+/GN+ and DN/GN were increased by 11.77% ～19.39% and 9.77% ～12.63% compared with CF.There was no significant difference between DN/GN and DN+/GN+.Therefore,the DN/GN should be popularized in strip compound cropping system of black soybean and millet.关键词
