玉米平作膜上精播技术研究
Research on the Accurate Sowing Technique of Flat Planting and Film Mulching of Maize
摘要
Abstract
In order to improve the yield of maize in semiarid region ,taking Xianyu 335 as the experimental mate-rials ,using the method of regional contrast ,accurate sowing technique of flat planting and film mulching were studied .The results showed that the accurate sowing technique of flat planting and film mulching could increase the ground temperature by 2~3℃ ,soil water storage by 13 .13% ,yield by 13 .87% and water use efficiency by 20 .40% than control .Accurate sowing technique of flat planting and film mulching could improve the topsoil temperature which had better effect on rain collection and water retention than the ordinary ridge tillage film covering technique ,and it could promote the growth and development of maize ,as well as increase crop yield and water use efficiency significantly .关键词
