摘要
试验观测了不同覆膜方式与覆膜时期对土壤水分、温度、旱地玉米生育期、生物学性状、产量及水分利用效率、经济效益的影响。经分析得出,全膜覆盖优于半膜覆盖,早覆膜优于晚覆膜。该地区玉米的最佳栽培方式为在扩大推广全膜双垄沟播秋季覆膜的基础上,进行全膜双垄沟播早春揭膜。
The paper observed the influence of different modes and periods of film mulching by trial on soil moisture and temperature,growth period,biological traits and yield of dry land corn,water use efficiency and economic benefit.By analysis it conclude that full membrane coverage is superior to half membrane coverage,and early membrane coverage is better than late membrane coverage.The best cultivation method of corn in this region is double furrow sowing with full membrane coverage and uncovering the membrane in early spring based on the expansion of double furrow sowing with full membrane coverage in fall.
