摘要
以中晚熟大豆长农18为材料,采用四因素二次回归正交旋转组合设计,研究了不同施肥量和种植密度对中晚熟大豆品种长农18产量的影响。建立了产量与种植密度和肥料之间的数学模型。结果表明:长农18高产栽培的施肥方案为尿素39.26~45.96kg·hm^-2,磷酸二氨168.79~196.44kg·hm^-2,硫酸钾70.86~79.77kg.hm^-2,种植密度24.8—25.9万株·hm^-2。
The four-factor quadratic rotational regression combination design was adopted to study the influences of different fertilizer application and planting density on the yield of middle-late-maturing soybean cuhivar Changnong 18. The mathematical models between the yield and fertilizer application and planting density were established and analyzed. The comprehensive cultivation measures on Changnong 18 were as following: nitrogenous fertilizer 39.26-45.96 kg ·ha^-1 ,phosphate fertilizer 168.79 - 196.44 kg·ha^-1 , potassium fertilizer 70.86 - 79.77 kg ·ha^-1 , planting density of 24.8 - 25.9 ×10^4 plants·ha^-1.
