摘要
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。
The design of quadrated general rotation regression was used in this test and the relations of yields to interseeding practices of prairie milkvetch (Astragalus adsurgens) were studied with earth elements and nodule bacteria. The function model was established. The regularity of main and mutual effect of all factors with yield was found. The best comprehensive agronomic practice was got by model analysis with computer.
