云南省保山市的蚕豆大部分种植于山区和半山区,在山地应用地膜覆盖蚕豆栽培技术,即盖膜与不盖膜(同地块)比,盖膜蚕豆的株高、有效枝、有效荚、荚粒数、百粒重等经济指标明显增加,从而大幅度增加旱地蚕豆的产量。1盖膜对蚕豆生长环境的影响1.1提高土壤温度蚕豆种植垄面覆盖地膜能提高土壤温度,由于地膜作用,土壤获得了辐射热,使垄面表土层温度升高,经过土粒的热量传递作用,使下层土壤温度逐渐得以提 Most of the faba beans in Baoshan City of Yunnan Province were planted in the mountainous and semi-mountainous areas. In the mountainous areas, broad-leaved cultivation techniques of mulching film were used, that is, the ratio of the covered membrane to the non-covered membrane , Pod number, 100-weight and other economic indicators increased significantly, thus greatly increasing the yield of dry beans. 1 cover film on the growth of broad bean environment 1.1 to improve soil temperature Broad bean ridge cover planting film can increase the soil temperature, due to the role of plastic film, the soil was radiant heat, the ridge surface soil temperature, through the soil heat transfer , So that the lower soil temperature gradually be raised
