摘要
在河南生态条件下,小麦播前土壤干旱的原因并非自然降水不足,而是人为因素所造成。多年的研究结果认为,秋收前后尽可能地蓄纳自然降水,并通过生物和农业措施减少土壤水分损失,合理高效地利用自然降水和土壤原贮水分是缓解土壤干早的根本对策。此外,本文还明确了我省不同地区蓄水保墒工作的侧重点。
In the ecological condition of Henan Province, the truthful reason that causes soil drought before sowing winter wheat is not little rainfall,but the people's factors. The research showed that catching and storing up rainwater to the maximum, reducing its loss to the minimun by biological and agricultural measures, and making full use of the rainwater and the original soil water were fundamental countermeasures to relax soil drought. Emphases of saving up soil water in different districts of Henan Province were made clear in the paper.
