摘要
采用3因素2次通用旋转组合设计研究了不同尿素、KC l施用量及种植密度对高蛋白春大豆品种福豆310产量的影响,建立了该品种在红黄壤条件下的高产栽培数学模型.在红黄壤旱地,该品种高产最佳农艺措施是:施尿素56.1-76.4 kg.hm-2,施KC l 89.7-124.1 kg.hm-2,种植密度31.4-34.7万株.hm-2.
Application experiment of urea, potassium chloride and plant density affecting output of high protein content spring soybean variety Fudou 310 was comprehensively conducted with the quadric universal rotation combination design. A mathematical model of high yield cultivation of the variety had been built up for red-yellow arid soil area. It is optimal to applicate 56.1 - 76.4 kg urea and 89.7 - 124.1 kg potassium chloride with the planting density of 314000 - 347000 per hectare in red-yellow arid soil area.
