Abstract
To understand the effects of straw return on soil fertility and premature senescence of maize experiments were conducted with long-term positioning pot experiment and laboratory analysis methods.The results show that,after improvement of soil fertility 6 years,soil bulk density in 0~ 20 cm soil layer was reduced by 1.53%~8.39%,total porosity of soil increased by 6.01%~15.65%,soil microaggregate composition structure improved,soil organic matter,total nitrogen,total phosphorus,available phosphorus increased,total potassium,available nitrogen and the content of rapidly available potassium stabilized,field capacity increased by 4.53%~10.25%,increased the yield of maize,improvement of soil fertility could promote the growth of maize root system,ensure moisture and nutrient uptake and use,effectively prevent premature senescence of maize.
