土壤风蚀是影响我省西部半干旱地区农牧业生产的主要自然灾害。引起本区土壤风蚀的主要因素是:春季干旱,大风频繁,地表裸露、疏松、干燥,植被覆盖率低,土壤(风沙土)抗蚀性差。我站通过近几年对耕作土壤风蚀规律的试验研究工作,发现垄作与平作相比有较显著的防止土壤风蚀的作用。本文是在试验研究工作的基础上,就垄作在防止土壤风蚀方面的作用进行探讨,试图为本区进一步推行垄作深松耕法提供一点科学依据。
Soil erosion is the major natural disaster that affects the production of agriculture and animal husbandry in the semi-arid western China. The main causes of wind erosion in this area are: spring drought, frequent winds, bare, loose and dry surface, low vegetation coverage and poor soil (aeolian sandy soil) corrosion resistance. Through the experimental research on the law of wind erosion of cultivated soils in recent years, I have found that there is a significant effect of preventing wind erosion caused by soil erosion. Based on the experimental research, this paper discusses the role of ridge in preventing wind erosion and attempts to provide a scientific basis for the further promotion of ridge-deep plowing in this area.
