| 摘 要： | 采用五因素四水平正交试验设计方法,对影响冈杂棉8号F1产量形成的密度、施纯氮量(N)、施纯磷量(P2O5)、施纯钾量(K2O)和喷DPC量等栽培因素进行了研究.结果表明,施纯氯量和喷DPC量是影响冈杂棉8号F1产量的主要栽培因素,其经济效益不仅受主要栽培因素对产量效应作用的影响,而且受栽培因素的价格因素的影响.因此,冈杂棉8号F1高产高效栽培技术措施以每公顷密度2.7万-3.0万株、施纯氮量337.5-412.5 kg·hm-2、施纯磷量90.0-120.0 kg·hm-2 、施纯钾量225.0～300.0 kg·hm-2、喷DPC量不超过45 g·hm-2为宜.

| Abstract: | The effects of different planting densities,N application,P application,K application and DPC application on the lint yield of the new hybrid cotton Gangza-8 were studied by means of five factors-four level orthogonal design. The results indicated that the amount of N application and DPC application were the major factors on the lint yield of the new hybrid cotton Gangza-8,and the economic profit was affected by the price of cultivation factors. The best combination of different managements for the film mulcling cultivation of hybrid cotton Gangza-8 were 27 000～30 000 plantlets,337.5～412.5 kg pure nitrogen,90.0～120.0 kg P_2O_5,225.0～300.0kg K_2O,and 45 g UPC per hectare. |
