摘要
本文采用二次正交旋转回归设计方法,经电子计算机运算,建立了密度、氮肥、钾肥和种块大小等四项技术措施与生姜产量关系的数学模型。应用计算机模拟,筛选出亩产2500～3000kg的综合技术体系优化组合方案。
A mathematical model of ginger yield related to seed-ginger size, plant density, nitrogen and potassium applications was set up by calculation on an electronic computer using the quadratic orthogonal rotation design method, based which an optimum combining scheme of synthetic technique systems was screened, i.e., to get 45,000kg/ha of fresh ginger must sow 113,000～126,000 seed pieces with each at 87.4～108.9g and supply 393.9～525.3kg nitrogen and 459.05～551.1kg potassium per hectare.
