摘要
本研究采用多个田间试验测得的参数，建立了优质稻银桂粘与主要农艺措施的数学模型，确定了置信区间，解析了农艺措施的产量效应及交互作用，优选出最佳组合方案为：４月７日～１０日播种，６．９～７．１叶移栽，亩插１２～１２．２万基本苗，亩施纯Ｎ９．３～９．５ｋｇ，Ｐ２Ｏ５７．９～８．１ｋｇ，Ｋ２Ｏ７．５～７．６ｋｇ，追肥分３次，可望获得５００ｋｇ以上的产量。结合研究该品种的主要生育指标、理想产量结构和叶龄模式理论。
By using the parameter from a series of field treatments,setting up the mathematical model between the quality rice variety Yingguizhan and main agronomic measures;fixing the confidence interval;analysing the yield efficiency and interaction of the agronomic measures. The optimum scheme selected were that sowing time was in 7～10 of April, transplanting in 6 9～7 1 leaf stage,seedling density per mu 120～122 thousand,applying N 9 3～9 5kg,P 2O 5 7 9～8 1kg,K 2O 7 5-7 6kg,top dressing 3 times.Yield more than 500kg could be obtained.Meanwhile,combinating the main growth index,structure of ideal yield,and theory of leaf age model,the essential cultivating measures for high yield and high efficiency was suggested.
