【摘要】 采用除草地膜全膜覆盖、普通地膜全膜覆盖、普通地膜半膜覆盖及不盖膜4种覆盖方式,对蔗田土壤水分、温度及甘蔗出苗情况进行比较。结果表明,全膜覆盖可以有效减少土壤水分蒸发,提高水分利用率,保持土壤温度,起到蓄水保墒、保温的作用。4种覆膜处理甘蔗出苗率及分蘖率大小依次为:除草地膜全膜覆盖>普通地膜全膜覆盖>普通地膜半膜覆盖>不盖膜。更多还原

【Abstract】 The changes of soil moisture,soil temperature,and seedling emergence of sugarcane seedbeds under four different plastic film coverage treatments(complete herbicide film mulching,complete conventional film mulching,half film mulching,and no film mulching) were studied. The results showed that the full film mulching could effectively reduce soil moisture evaporation,increase water use efficiency,maintain soil temperature,and play a role in water storage,preservation,and heat preservation. The seedling emergence rate and tillering rate of the four treatments was as follows: full herbicide film mulching>full conventional film mulching>halffilm mulching>no film mulching.更多还原
