旱地玉米不同覆膜方式与覆膜时期节水增产效应研究OA
Study on the Water-saving and Yield-increasing Effects of Dryland Corn in Different Film-covering Modes and Period
探讨了不同覆膜方式与覆膜时期下旱地玉米的节水增产效果。结果表明，全膜双垄沟播是节水增产的最佳覆膜栽培模式，较半膜平铺覆盖栽培增产22.4%，土壤耗水量减少23.71 mm，水分生产效率提高0.45 kg/mm，经济性状均明显优于半膜平覆。覆膜时期以全膜双垄秋覆膜最好，较半膜平铺顶凌覆膜增产21.0%，土壤耗水量减少11.20 mm，水分生产效率提高0.27 kg/mm。
The effects of water-saving and yield-increasing effects of dryland corn in different film-covering modes and period was explored . The results showed that the best film cultivation methods water-saving and yield-increasing of was cultivation techniques of ditch sowing in double ridge mulched with plastic films,the yield was 22.4% higher than of the check of flat mulched with plastic half films,the soil water consumption decrease 23.71 mm,the water productiv…查看全部>>
