本文采用三因子回归最优设计的方法,研究了人工控制水分条件下棉花高产优质的施纯氮量、密度、灌溉定额等三项农艺措施间的关系,建立了总皮棉产量、霜前皮棉产量与三项主要农艺措施的函数模型;通过数学模拟筛选出了每公顷产皮棉1875公斤,霜前皮棉1650公斤以上的最佳农艺措施组合方案。
In this paper, the optimal design method of three-factor regression was used to study the relationship between the three agronomic measures such as high pure and high yield nitrogen, density and irrigation quota under artificial control of water condition, and the relationship between total lint yield, And three main agronomic measures. Through mathematical simulation, the optimal combination of agronomic measures of 1,875 kg per hectare of lint and 1650 kg of lint before frost was screened out.
