中文摘要:
      在黑龙江西部干旱地区,2007~2008进行了秋旋、深松、春旋和原垄卡四种耕作措施以及中耕对土壤温度影响试验。结果表明:原垄卡和深松能有效地调节土壤温度,在早上8∶00温度较低的时候,提高地温0.51℃,在温度较高的下午14∶00,能减缓土壤温度升高过快。中耕在高温时能极显著提高地温12℃,但温度下降也很快,对调节土壤温度没有积极作用。综合来看,在黑龙江西部干旱地区,原垄卡和深松且不中耕的耕作措施可使土壤的温度保持在一个相对稳定的状态,创造良好的农田小气候,有利于作物的生长;而旋耕措施不适宜该地区农业耕作。
英文摘要:
      Experiments were conducted to study soil temperature in dry areas of west Heilongjiang field under four cultivation treatments and inter-tillage.The result show that:No tillage and loosening method regulate soil temperature effectively.They increase soil temperature by 0.5～1℃ in the morning when air temperature was low, but reduced the rate of temperature increment in the afternoon when temperature was higher.Inter-tillage increases soil temperature by 1～2℃ when temperature is high, but also increases the rate of temperature decrement.Therefore no tillage and loosening method without inter-tillage could keep the stability of soil temperature and is beneficial for the crop growth in dry areas of west Heilongjiang, while rotary tillage and inter-tillage are unsuitable for farming in the area.
