连续2a进行了秸秆堆腐还田技术应用试验研究。结果表明:秸秆堆腐还田具有改良土壤,培肥地力,增加作物产量的作用。秸秆堆腐还田土壤全年作物产量增加了4.1%～5.6%,有机质含量增加0.9～1.5g/kg,速效钾含量增加3.2～5.6mg/kg,速效磷含量增加1.3～2.3mg/kg,容重降低0.07～0.13g/cm3。
Successive 2a straw stalked into the field technology application test research. The results showed that straw returning to the soil could improve the soil fertility and increase the yield of crops. The annual crop yield increased by 4.1% -5.6%, the organic matter content increased by 0.9-1.5g / kg, the available potassium content increased by 3.2-5.6mg / kg, the available phosphorus content increased by 1.3-2.3mg / kg, Bulk density decreased 0.07 ~ 0.13g / cm3.
