本试验研究了7项主要栽培因素对黑龙港生态区旱地棉田棉花的生育及产量的效应,建立了不同降水年型综合栽培措施与产量的回归方程,通过模拟寻优,筛选出了正常降雨年型产籽棉3000kg/(hm)~2,干旱年型产籽棉2625kg/(hm~2)和丰水年型产籽棉3450kg/(hm)~2水平下的优化措施组合,为该区旱地棉生产提供了科学依据。
In this study, the effects of seven main cultural factors on the growth and yield of cotton in upland cotton field in Heilonggang ecological zone were studied. The regression equations of comprehensive cultivation measures and yield of different annual precipitation years were established. Through the simulation optimization, the normal rainfall years The optimum combination of 3000kg / (hm) ~ 2 production seed cotton, 2625kg / (hm ~ 2) dry annual seed cotton production and 3450kg / (hm) ~ 2 cotton seed production per year Provide a scientific basis.
