齐齐哈尔地区保护性耕作技术探讨

Research on Conservation Tillage Technology in Qiqihaer Area

黑龙江省保护性耕作技术体系已趋完善,该项技术在平作区已大面积推广应用。为研究垄作区保护性耕作技术体系,在齐齐哈尔市玉米产区开展了“一深松两少免一覆盖”耕作模式的试验。通过试验对比分析得出结论,保护性耕作耕地土壤含水量和平均地温均较传统耕作提高,有利于作物生长,玉米产量高于传统垄作区。

The conservation tillage technology system in Heilongjiang province has been improved,and the technology has been widely promoted and applied in the flat farming area.In order to study the conservation tillage technology system in the ridge cropping area,the experiment of one deep loosening and two less without one covering tillage mode was carried out in the corn producing area of Qiqihar city.It is concluded that the water content and average geothermal temperature of conservation tillage soil are higher than that of traditional tillage,which is conducive to crop growth,and the corn yield is higher than that of traditional ridge cropping area.
