摘要
干旱是制约玉米生产的主要因子。试验研究7种不同覆膜方式的土壤含水量、土壤温度、玉米生育期、农艺性状及产量,探求不同覆膜方式对半干旱地区玉米产量的影响。结果表明,顶凌覆膜优于春覆膜,全地面覆膜优于半覆膜平铺,其中全膜顶凌双垄沟栽培模式产量达到12 691.9 kg/hm2,较普通种植模式增产46.10%,较裸地种植增产77.98%,是一项适合半干旱地区的玉米高产栽培技术。
The main factor to constraint maize growth is drought. The objective of this experiment was to study the effects of different plastic mulching modes on the yield of semiarid maize. The effects of seven different modes of cov- ering on soil moisture content, soil temperature, growth stages, agronomic properties and yield of maize in the semiarid were studied. The results showed that the full mulching on double ridges in early spring was better than the full mulching on double ridges in middle spring, and the full mulching on double ridges was better than the half fiat mulching before sowing; the early film mulching time was batter than the latter. The yield of maize production with the full mulching on double ridges in early spring was 12 691.9 kg/ha, which was higher 46.10% than the half fiat mulching on double ridges before sowing and higher 77.98% than non-mulching. It is a reasonable technical for maize productive in the semiarid.
