我省属两熟棉区,常年早春低温多雨,光照条件差,土壤排水不良,严重影响一播全苗和壮苗早发;而棉花中后期,特别是入秋后,阴雨天多,棉桃不能正常吐絮,以致不少伏前桃、伏桃霉烂,秋桃不能到手。为了解这一突出问题,1982年我们在黄潭公社新华大队农科站进行了棉花地膜(聚乙烯吹塑)覆盖栽培试验。试验证明,棉花地膜覆盖有增温、保墒、防涝、保全苗、争早发、多结伏桃、早熟增产、提高收益的作用。据8月15日测产,3月28日、4月5日、4月10月、4月15日四期地膜覆盖栽培亩产皮棉依次达209.10斤、193.1斤、193.7斤、168.8斤,比4月15日对照149.4斤依次增产40.0%、29.3%、29.7%、13.0%。
Two provinces in our province cotton area, low temperature and rainy all-year-round early spring, poor light conditions, poor drainage of soil, seriously affecting the whole plant seedlings and seedlings early hair; and cotton in the late, especially after autumn, cloudy and rainy days, Normal bolting flocculation, resulting in a lot of volt V, peach rot, autumn peach can not get it. In order to understand this outstanding issue, we carried out cotton mulching (polyethylene blow molding) covering cultivation experiment at Xinhua Brigade Agricultural Station of Huangtan Commune in 1982. Experiments show that cotton mulching with warming, moisture, waterlogging, preservation of seedlings, fight early hair, multi-knot peach, premature production, increase returns. According to August 15 measured production, March 28, April 5, April 10, April 15 four plots covering mulberry cultivation of milled cotton followed by 209.10 pounds, 193.1 pounds, 193.7 pounds, 168.8 pounds, April 15 control 149.4 kg followed by an increase of 40.0%, 29.3%, 29.7%, 13.0%.
