玉米田覆盖化学除草地膜对后茬冬小麦生长发育的影响
Effect of covering chemical weeding film in maize field on growth and development of following winter wheat
摘要
Abstract
Application of chemical weeding film in maize field with whole mulching on double ridges was a newly effective way to solve weeds problem and significantly improve the production efficiency.However, the safety of herbicide residues in soil was not clear for following winter wheat.To understand the effects of chemical weeding film on the seedling emergence, plant height, tiller, biomass, ear characters and yield of following winter wheat, a field experiment, covering chemical weeding film and covering plastic film in maize field with whole mulching on double ridge, was conducted in an arid area of Longdong, Gansu Province.The result showed that, compared with covering plastic film, covering chemical weeding film was not significantly different in seedling emergence rate, plant height, tiller number, dry root weight, dry shoot weight, root-shoot ratio, productive panicle number, grain number per spike and grain yield in following winter wheat, while 1000-grain weight was significantly different with an increase of 1.6 g.Therefore, cover-ing chemical weeding film in maize field with whole mulching on double ridges had no effect on the development of following winter wheat.关键词
