Abstract: Previous studies had showed that straw mulching treatment can reduce the atmosphere pollution compare to burning straw. But the most important effect of it is that it can efficiently accommodate soil water, fertility, soil atmosphere and heat. It can also incerase soil porosity, soil water permeability, the content of water stable aggregate, soil organic matter, soil available nutrient, the soil microbial biomass and enhance the activity of soil enzyme. Meanwhile, straw mulching treatment can decrease the contamination of speciese heavy metal to soil. Considering the economic benefit, mulching straw can also improve crop yields. In conclusion, mulching straw which is one of the efficient measures of the agricultural sustainable development can improve ecological, social and economical benefits.
