| 中文摘要: |
| 以中棉43号为材料,采用“3414”方案,在新疆沙雅新垦农场,通过田间小区试验,研究了地面灌溉条件下不同水肥耦合水平对棉花产量的影响,并建立了棉花产量的水肥回归数学模型。结果表明:不同水肥耦合水平对棉花产量都有显著影响;各因素对棉花产量的效应顺序为:施磷量>灌溉量>施氮量;各因素间耦合效应顺序为:氮、磷>氮、水>磷、水;水肥调控的最佳组合为:氮肥用量为545.55 kg/hm2,磷肥用量为199.8 kg/hm2,灌溉量为6 429.3 m3/hm2。 |

| Based on the design of“3414” ,with the cotton variety of Zhongmian No.43 as test material in Shaya County，the coupling effects of water and chemical N，P fertilizers and water on cotton yield were stud-
ied, and a regressive mathematical model was set up based on the cotton yield by quadrat ic regression analysis. The results showed that all test coupling levels of w ater and chemical fertilizers had significant effects on cotton yield. The yield-increasing effect of test factors w as in the order of P application rate irrigation amount> N application rate, w hile the coupling effect of w ater and chemical fertilizers w as in the sequence of N and P> N and water>P and water. For cotton yield, the optimum irriqat ion amount and application rates of chemical
fertilizers were 545.55 kg/hm^ of N and 199.8 kg/hm' of P and 6429.3 m3/hm2 of water. |
