国内秸秆还田技术探究

摘要

Straw is a large number of renewable resources in China.Inappropriate treatment method such as accumulation of waste and incineration will cause environmental pollution and resource waste.The development of straw application is too late and is not mature enough in China.This paper reviewed method and effect of straw application in China.Straw application mainly includes direct and indirect ways.Straw application can not only improve local soil physical and chemical properties but also play an important role in soil and water conservation.Straw can increase the soil fertility in the process of decomposing and nutrition elements.It can also promote the absorption of nutrients on crops.%综述了国内秸秆还田方式以及秸秆还田效应.指出了秸秆还田主要有直接还田和间接还田方式.秸秆还田之后,不仅能够改良当地的土壤理化性质,同时也起到了保水保土的效应.秸秆在腐解过程中产生的营养元素能够增加土壤肥力,还能促进作物对营养元素的吸收.
