摘要
本文通过函数方程进行模拟试验,得出了中豆19号不同产量水平各农艺措施配方。频率分析表明,亩产175kg以上,密度(x_1)和氮索(x_2)取值域0.525—1.292,磷素(x_3)取值域0.200—0.77三因素作用序列为x_3>x_1>x_2。氮磷比例1:2.0—1:1.5。
The formulas of agricultural methods in different yield levels were obtained through the simulated test using the function equation. The frequecy analysis showed that the yield was over 175kg/mu,the ranges of plant density (x1)and nitrogen ( x2 ) were 0.525-1.292, and phosphorus was(x3) 0.200-0.797. The effectss of above factors were X3>X1>X2 in sequence and the N/P ratio was 1 : 2.0-1 : 1.5.
