| 摘 要： | 采用3因素5水平通用旋转组合试验设计方法,研究了棉花新品种C111的种植密度、氮肥和钾肥对产量及主要性状的影响,建立了相应的数学模型,得出3因素对C111籽棉产量的作用为钾肥〉密度〉氮肥,在-1.682≤X≤1.682水平范围内,即密度2500株/667m2,纯N为30kg/667m2,纯K为15kg/667m2,C111棉花品种可达最高产量,得出最高产量为244.7kg/667m2。

| Abstract: | The relationships of seed cotton yield and density,nitrogen,potassium fertilizers were studied,and amathematic model involving the three factors and seed cotton yield was established by using general rotational regression design.The results indicated that,under the condition of this experiment design,factors affecting seed cotton yield were in such an order as potassium fertilizers plant density nitrogen fertilizers,In the horizontal range of-1.682≤X≤1.682,plant density was 2500palnts/667m2,nitrogen fertilizers was 30kg/667m2,potassium fertilizers was 15kg/667m2,C111 will be up to the h igh yield of cotton varieties,and the high yield was 244.7kg/667m2. |
