摘要: 本文从穗重与穗数的关系及经济产量与生物产量的关系两种不同的角度出发,分析了合宜密度问题,并提出了一些概括这些关系的经验公式。根据这些公式可以求出合宜密度范围。文中对不同肥力下的合宜密度、经济上合算的密度等问题,以及前人所提出的产量~密度函数关系进行了讨论。

Abstract: In recent years many works have been published concerning the problem of optimal plant-ing density of crops and much attention has been paid to the density at which maximumyield is.attained.Since this density is not always the most profitable one,what is neededin practice is the yield-density curve
