摘　　要：研究了ＤＰＣ系统化控对不同密度条件下麦套春棉产量和品质的影响。结果表明，ＤＰＣ系统化控对不同密度条件下麦套春棉都有显著促进作用，表现为棉铃干物质积累加快；成铃时空分布合理，烂铃减少，优质铃增加。棉花产量有明显提高，对纤维品质无不良作用。优化组合是Ｂ２Ｔ３，Ｂ２Ｔ１和Ｂ３Ｔ２，皮棉增产率分别为２２．８％，２８．４％和４３．３％。其中。A study was carried out on the effects of DPC systematic chemical control on the yield and qulity of interplanting spring cotton with winter wheat under different density.The results showed that DPC systematic chemical control had significant promoting effects on interplanting spring cotton with witnter wheat under different density.The details were as follows :1)The accumulation of dry matter in cotton fruits was quickened and the boll weight enhanced;Also,a more reasonable time and space distribution of boll setting,a decreased number of rotton bolls and an increased number of good bolls were observed.2)chemical control could significantly improve the lint yield,and had no negetive influence on the quality of cotton fibre.Among all the combinations,B 3T 2 was the best which was followed by B 1T 3 and B 2T 1,and the increasing rate of lint yield were 43.3%,22.8%and 28.4%,respectively.
