两熟棉区,小麦良种南大2419生长期约200天,棉花良种岱子棉15号,生长期也约200天。因此棉花必须播种在小麦行内,与小麦间作,因而,棉苗长期被麦行荫蔽,生长瘦弱,而且棉花播种前施肥,整地等管理工作及小麦收获时机械化作业,也很困难。 华中农科所及湖北省各试验站曾就小麦宽窄行条播,在麦行内为棉花犂地施基肥、间苗等一系列的麦棉间作管理作业上进行了研究,提出了改善办法,并在生产上已大面积推广,对获得两熟丰产,起了一定的作用,但要在基本上解决两熟的矛盾,尚待进一步的研究,一般说来有下列几个途径: (1)从栽培方面继续提高改进麦棉间作技
Double ripe cotton area, wheat seedling Nanda 2419 growing period of about 200 days, cotton seed Dai Dai cotton on the 15th, the growth period is also about 200 days. Therefore, cotton must be sown in the wheat line and intercropped with wheat. Therefore, the cotton seedling has long been shaded by the wheat bank and its growth is emaciated. Moreover, it is also very difficult to manage the cotton before sowing such as fertilizing, site preparation and mechanization during wheat harvesting. Huazhong Agricultural Research Institute and various pilot stations in Hubei Province have conducted a study on a series of wheat-cotton intercropping management work on cotton plows such as basal fertilizer and thinning for cotton plowing in the wheat bank, and proposed improvement measures. Has been large-scale promotion, access to two-crop yield, played a certain role, but to basically solve the conflict between two crops, yet to be further studied, in general, the following ways: (1) from the cultivation Continue to improve and improve wheat-cotton intercropping techniques
