作物最终产量是许多因子x_1、x_2、x_3…x_n的函数。这些因子可分为四类:光(L)、热(T)、水(B)和养料(Q)。因为每块农田都具有各自的一列决定产量的参数值,所以其产量M可用下式表示: M=f′(x_1,x_2,x_3,…,x_n) (1) M=f(L,T,B,Q) (2) 作物产量M可以是总生物质、商品量或其他物质形式(如糖、油、蛋白质等)。很明显,每种作物或品种相应都有一列能保证它获得最高产量M。的最适宜参数值L_0、T_0、B_0和
The final crop yield is a function of many factors x_1, x_2, x_3 ... x_n. These factors fall into four categories: light (L), heat (T), water (B) and nutrients (Q). Since each cropland has its own set of parameter values that determine yield, the yield M can be expressed as: M = f ’(x_1, x_2, x_3, ..., x_n) (1) M = f (L, T, B, Q) (2) Crop Yield M can be total biomass, commercial product, or other material form (eg, sugar, oil, protein, etc.). Obviously, there is a column for each crop or variety that guarantees the highest yield of M. The most suitable parameters L_0, T_0, B_0 and
