尉犁地区,历年平均无霜期211天,10℃以上积温4175.8℃,年降水量38.7毫米,日照时数2987小时,全部是灌溉农业,对棉花栽培有着得天独厚的自然条件。但是,尉犁县春季气温低且不稳,秋季降温快,干旱,盐碱重,直接影响棉花的产量和质量。为发挥棉花生产潜力,探讨高产稳产栽培途径,结合本地区的生态条件验证地膜植棉的各种环境效应和对地膜植棉的主要栽培措施。今年在兴平公社一大队二队,10亩地上进行了地膜植棉试验,并设对照田一亩。 一、试验情况
Yuli region, the average annual frost-free period of 211 days, 10 ℃ above the accumulated temperature 4175.8 ℃, the annual rainfall of 38.7 mm, sunshine hours 2987 hours, all irrigated agriculture, cotton cultivation has a unique natural conditions. However, the spring in Yuli County is low and unstable in spring, with rapid cooling in autumn, drought and salinization, which directly affects the yield and quality of cotton. In order to give full play to the potential of cotton production and to explore the cultivation methods of high and stable yield, the various environmental effects of plastic film-mulching and the main cultivation methods of mulching and cotton planting were verified with the ecological conditions in the area. This year in Xingping commune a brigade two teams, 10 acres of land on the ground film cotton planting test, and set the control field a mu. First, the test situation
