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,施纯氮量和喷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。

摘  要:
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 P2O5,225.0~300.0kg K2O,and 45 g DPC per hectare.
