玉米秸秆机械粉碎深翻还田培肥技术效果研究

Study on the Effect of Mechanical Pulverization Technology of Corn StalkDeep Tillage Returning to Field for Fertilizing

利用农业机械就地将玉米秸秆粉碎、深翻还田对于土壤肥力提升效果显著。在铁岭县进行玉米秸秆机械粉碎深翻还田培肥技术应用试验,结果表明,实施秸秆深翻还田可以改善玉米的生育性状,对玉米增产具有明显作用;可以改善土壤的理化性状,降低土壤容重,改良土壤结构,提高土壤有机质含量,培肥地力;还可以降低投入产出比,提高经济效益。

Using agricultural machinery to crush corn stalks and turn them back into the field has a significant effect on improving soil fertility.In Tieling County,the application test of mechanical pulverization of corn straw in deep tillage turning for fertilizing was carried out.The results showed that the application of mechanical pulverization of corn straw in deep tillage turning could improve the growth characteristics of corn,and had an obvious effect on increasing the yield of corn;It can improve soil physical and chemical properties,reduce soil bulk density,improve soil structure,increase soil organic matter content,and enrich soil fertility;It can also reduce the input-output ratio and improve economic benefits.
