黑龙江省几种主要土壤的粘着性研究

<正> 土壤粘着性是土壤的重要物理机械性之一,当土壤处于粘着范围内进行耕作时,土壤能强烈粘着进行耕作工作农机具的犁板、圆盘和齿轮等。这样,不但给耕作的农机具增加巨大的阻力,而且耕作质量十分恶劣。为了适应我国农业机械化的发展,找出农机具进行土壤耕作消耗能量最小和耕作质量最佳的土壤粘着性范围,因此对土壤粘着

THE STUDY ON THE SOIL STICKNESS OF SEVERAL MAIN SOIL TYPES IN HEILONGJIANG PROVINCE

The change of soil stickness capacity depends on the variation in contents of the soil moistune. It is different that the stickness of the variation of soil types in Heilongjiang province. According to the study on the factors of effect of soil stickness, we can improve soil stickness by means of agricultural measures such as increasing soil organic matter, changing composition of cations and soil mechanical compound. For saving energy and having better tillage quality the tillage practice should be done under optimum contents of soil moisture and minimum soil stickness.
