就黄淮海平原精种高产区，在麦棉套种的基础上，进一步提高高产棉田的棉花产量，从种植方式角度，围绕提高棉花产量的种植方式及其棉花增产的机理等问题进行了探讨，研究得出：３—２—３—２式小麦套种短季棉与中熟棉模式是高产棉田再高产的有效种植方式。与常规３—２式麦棉套种方式相比，小麦产量不减，皮棉产量提高１７．２％；以２行短季棉替代２行中熟棉形成的短季棉与中熟棉复合群体能够充分发挥不同熟性棉花品种间在生育期、株型、蕾铃发育进程等生长发育特征特性的差异，利用它们在发挥群体中占据的时间、空间生态位上的差异，使复合群体结构动态趋于合理，在一定程度上解决了高产棉田生长后期群体发育过大造成冠层郁蔽，通风透光条件恶化，蕾铃脱落率高的不足，从而获得高于单作的超额产量；但是并非不同熟性的棉花品种任意搭配在一起就能增产。不适宜的搭配方式（如６—２—２式），不仅不能发挥早中熟棉生态特征特性方面的差异，反而会使其生态位重叠，加剧两者之间的竞争，导致不增产甚至减产。选择合理的短季棉与中熟棉配套种植方式是获得增产的关键。
On the basis of cotton and cotton intercropping, the cotton yield in high-yielding cotton fields was further improved based on the interplanting of wheat and cotton. The planting methods and the mechanism of cotton yield increase were discussed in terms of planting methods. The conclusion is: 3-2-3-2 wheat intercropping short-season cotton and middle-maturing cotton is an effective planting method for re-yielding high-yielding cotton. Compared with the conventional 3-2 wheat-cotton intercropping method, the wheat yield did not decrease and the lint yield increased by 17.2%. The short-season cotton with two-row short-season cotton replaced the short- Give full play to different maturity cotton varieties in growth period, plant type, the process of development of buds and other growth and development characteristics of the differences, the use of them in the group to play the time occupied by space differences in niche, so that the complex population dynamics To a certain extent, this method solves the problem of excessively large population development in the high-yielding cotton field resulting in darkening of the canopy, worsening of the ventilation and light conditions and high drop-out rate of the buds, thereby obtaining a higher yield than the single crop; however, it is not different Any combination of mature cotton varieties can increase production. Not suitable with the way (such as 6-2-2 style), not only can not play in early maturing cotton ecological characteristics of the differences, but will make its niche overlapping, exacerbating the competition between the two, leading to not increase production or even cut . Select a reasonable short-season cotton and maturing cotton supporting planting is the key to yield.
