摘要
不同栽培密度对高产大豆新品种临豆九号产量及农艺性状的影响试验结果表明,密度与株高呈正向指数函数关系,与单株荚数和单株粒数呈负向指数函数关系,与叶面积系数呈双曲线型增长,与大豆产量间也呈双曲线型关系;当密度为21.719 6万株/hm2时,可获得最佳理论产量3 925.99kg/hm2。
Effect of different cultivation density on yield and agronomic characters of new soybean variety Lindou 9 was studied.The results indicated that the density had positive exponential,and the negative exponential relation,to the number and the single number of seeds and the hyperbolic linear relation to the leaf area coefficient,also the hyperbolic linear relation to the soybean yield.When the density was 217 196 plants/hm2,the best theory yield might be abtained 3 925.99kg/hm2.
