optimum plant density的意思|示意

Optimum plant density affects the use efficiency of crops production factors. To define it on peanut in Argentina we applied asymptotic model (Eq. 1).

种植密度是影响作物生产效率的关键因素之一，因此将渐近模型(方程1)应用到阿根廷的花生种植密度决策中。

The effect of plant density on grain yield was also not significant for rice variety tested, the optimum plant density was about300,000 to375,000 hills per ha .

供试水稻品种的植株密度对籽粒产量的影响也未达到显著水平，最佳植株密度为每公顷300，000~75，000篼。
