锦州地区玉米保护性耕作试验研究

Experimental Study on Protective Tillage of Maize in Jinzhou Area

以锦州市义县地区的乡级高标准黑土地保护性耕作应用基地的调查数据为基础,从土壤理化指标、出苗率、株高、产量等方面与传统耕作模式进行对比试验。结果表明,均匀行免耕和苗带碎旋耕耕作模式在提升土壤温度、玉米出苗率、植株高度与籽粒产量等指标方面均高于传统耕作模式。

Based on the survey data of township high standard black land conservation tillage application base in Yixian county,Jinzhou City,the experiment of soil physicochemical index,seedling rate,plant height and yield were compared with the traditional tillage mode.The results showed that the soil temperature,seedling emergence rate,plant height and grain yield of maize were all improved by the uniform line no-tillage and seedling belt broken rotary tillage modes compared with the traditional tillage mode.
