东北黑土区玉米保护性耕作技术模式研究

Study on Technique Model of Conservative Tillage in Maize in North-east of China

针对东北黑土区土壤风蚀和水蚀严重、自然降水利用率低、土壤有机质下降、耕层变浅等问题,研究了玉米宽窄行留高茬交互种植技术和灭高茬整地保护性耕作两种技术模式,该技术对保护黑土生态环境,发展可持续农业具有重要意义。

The conservative tillage model of width/narrow high stubble alternation and operating field of smashing high stubble was studied for soil structure was damaged by wind and raining, utilities rate of raining were low, soil fertilizer was degenerated, and bottom layers of plow were become thin in the north-east black soil zone of china. This technique will be benefit for improving ecological environment of black soil and constructing sustainable agriculture in the future significantly.
