夏直播绿豆规范化栽培密度与氮肥优化配置研究
Optimized Allocation Research on Standardized Planting Density and Nitrogen Fertilizer of Summer-Sowing Mung Bean
摘要
Abstract
Using the quadratic saturation D-optimum design,the yield effects of N application rate and planting density on summer-sowing mung bean were studied,and corresponding mathematical models were developed.The results showed that the density effect was greater than the N fertilizer effect,and they had negative interaction.The N fertilizer could be appropriately reduced through increasing density.The maximum yield of mung bean could be up to 1 664.45 kg/hm2 under the optimal combination of N fertilizer (53.73 kg/hm2) and density (141 700 plants/hm2).The combinations of yield exceeding 1 600 kg/hm2 were N fertilizer of 47.96 ～59.54 kg/hm2 and density of 134 500 ～148 800 plants/hm2.关键词
