【摘要】 黑土耕垦后 ,肥力性状发生很大变化 ,大多数则表现为自然肥力逐渐下降的趋势 ,并派生出降低土壤生产力水平的障碍因子。根据农田黑土调控措施试验结果分析 ,深松耕法水分利用效率提高 12 7% ,组合施肥水分利用效率提高 14 5 % ;深松耕法提高化肥利用效率 5 7% ,组合施肥提高化肥利用效率 9 8% ,深松 +组合施肥提高化肥利用效率 11 2 %。表 5 ,参 9。

【Abstract】 After tillage, black soil fertility properties have changed a lot The main expression is decrease of nature fertility, and brings the impedimental factors that reduce the soil production capacity Therefore, many treatments for adjusting and controlling these impedimental factors were conducted in the experimental field The results indicate, according to the analysis derive from the experiments, the water availability increase 12 7% , 14 5% with treatments of deep loosing tillage and combined fertilizer respectively; fertilizer availability increase 5 7% , 9 8% and 11 2% with the treatment of deep loosing tillage, combined fertilizer and deep loosing tillage + combined fertilizer respectively
