摘    要:采用D-饱和最优设计法对播期和播量耦合与小麦越冬死苗的关系进行了研究,结果表明:在10月25日播种、播量为8万基本苗/667 m2条件下,小麦的越冬死苗率最低;晚播和减少播量有利于降低越冬死苗率;播期对小麦越冬死苗率的影响大于播量。

关 键 词:播期  播量  D-饱和最优设计  越冬死苗  小麦

Abstract:The effect of coupling of sowing date and planting density on the mortality of overwintering wheat seedlings was studied by using D-status design.The results showed that the mortality of wheat seedling was the least when being sowed on 25th,October with the seedling density of 80000 plants/667m2.Late seeding and low seedling amount could decrease the mortality.Sowing date had more effect on mortality than seedling amount.
Keywords:Sowing date  Seedling amount  D-status design  Dead seedling in overwintering  Wheat
