摘要
试验采用浙江博龙生态有限公司生产的多功能全降解液态地膜,玉米品种选用先玉335,比较液态地膜与普通地膜土壤墒情、温度、出苗情况、玉米产量以及产量构成因素,结果表明:地膜覆盖技术能促进土壤保温保墒,并能提早出苗,提高出苗率,促进幼苗植株生长,增加产量。普通地膜在玉米生育前期保温保墒效果较好,液态地膜收获时产量最高,在产量增加的同时减少对环境的污染,建议广泛使用。
The test uses multi functional Zhejiang Bolong ecological limited production of degradable liquid film,corn variety Xianyu 335,comparison of liquid film and ordinary film of soil moisture,temperature,germination,maize yield and yield component factors,results showed that： plastic film mulching technology can promote soil moisture and heat preservation,germination,seedling emergence rate,promote seedling growth,increase yield.Common plastic film in the early growth stage of maize moisture insulation effect is good,liquid film harvest yield was highest,at the same time increase the yield reduction of environmental pollution,extensive use of advice.
