摘要: 本文采用旋转设计所作的三因素试验测得的参数,建立了子棉产量、皮棉产量、霜前花、纯收益等函数模型。通过计算机模拟,筛选出兼顾高产、优质、高效益的综合农艺措施为;每亩3.2-3.9千株,施纯氮11.3-12.6公斤,14.5-15.5个果枝打顶,并对试验因子的主效应及交互效应进行了剖析。

Abstract: In this test the gyration method was adopted to obtain the parameters in the experiment of three factors,and functional models of unginned and ginned cotton yield,income and prior to frost cotton have been estabished by the obtained parameters.Through the simulation and sieving by computer,comprehensive technic measures have been developed to reach a high yield,top quality and high benefit cotton,which include rational close planting of 3200-3900 plants per mu,11.3-12.6 kilogram pure nitrogen per mu and top removal from the fruiting branch bearing 14.5-15.5 fruits.The main and mutual effects of the tested factors have also been analysed.

Key words: Cotton, High yield and fine quality, Quadratic regression design
