摘要
在潮土性水稻土上，采用三元二次通用旋转组合设计，对影响鄂粳杂１号产量的主要养分因子氮、磷、钾进行了３因素５水平的田间试验研究，建立了产量对３因子的肥料效应函数模型，并运用边际效应理论对模式进行分析研究，确定了经济最佳施肥量。
In this paper,the relationship between two lines hybrid rice E Gen Za No.1 yield and fertilizer response was studied by using the quadratic rotation combinative design.The production function for nitrogen, phosphorus and potash was set up and analysed. The profit maximizing fertilizer levels was determined. [WT5”HZ〗
