本试验应用二次回归通用旋转设计试验方法,研究了沙打旺补播技术(保水剂、稀土、根瘤菌)与产草量的关系,建立了数学模型,找出了各因素单效应及互作对产量的作用规律。并利用微机摸拟试验,得出了补播沙打旺的综合农艺措施。
In this experiment, the quadratic regression general rotation design test method was used to study the relationship between the sowing technology of Astragalus adsurgensis (aquasorb, rare earth and Rhizobia) and the amount of grass production. A mathematical model was established to find out the single effect and interaction of each factor For the law of the role of output. And the use of computer simulation test, reached a comprehensive planted sowing Wang agronomic measures.
