黑土坡耕地治理研究

Study on harnessing the slope farmland of black soil

通过对海伦前进小流域黑土坡耕地的耕作措施、施肥措施、生物措施等试验 ,采用多年、定点、定位取样分析与监测 ,摸索出了有效的治理途径 ,使坡耕地水土流失得到了基本控制 ,土壤微生物量增加 ,水分利用率提高 ,作物产量增加 ,土壤肥力基本保持平衡 ,为侵蚀黑土区综合治理提供技术支撑。表 2 ,参 3。

Experiments of cultivation,fertilizer and biology are carried out in Qianjin minor drainage area of Hailun city. Through sampling, analysis and measures of monitor locatedly over years, an effective way to harness the slope farmland of black soil area is explored out. As the result of it, loss of water and erosion of soil in this area has been controlled basically. Soil microbiomass increases. Water utilization efficiency is enhanced. Yield of crops increase. Soil fertility is almost kept in balance. All of these have priovided technological support for harnessing the erased black soil area comprehensively.
