墒即是水。水是土壤肥力最重要最活跃的因素之一。土壤与水,作物与水之间,经常在相互作用、相互影响下进行着蓄水、保水、供水的复杂变化。我们必须用辩证唯物主义的哲学思想,从土壤的内在特性和作物生长发育规律的相互关系中来正确认识和解决抗旱保墒的问题。蓄是基础。土壤剖面上下层次的整体结构和特性,对土壤水分的上下运行和蓄水保水性能影响极大。如我旗长胜公社马架子大队的上等土壤,亩产年年保持在千斤以上。在8寸以上的活土层中,表层疏松绵软,富大孔隙,有利于
Moisture is water. Water is one of the most important and active elements of soil fertility. Between soil and water, between crop and water, the complex changes of water storage, water retention and water supply are often carried out under the influence and interaction of each other. We must correctly understand and solve the problem of drought and soil conservation based on the dialectical materialist philosophical thinking and from the relationship between the inherent characteristics of soil and the law of crop growth and development. Saving is the foundation. The overall structure and characteristics at the top and bottom of the soil profile have a great impact on the up and down movement of soil moisture and water retention performance. As my flag Changsheng community horse shelf brigade soil, per mu to maintain at least a thousand pounds. Living soil above 8 inches, loose surface soft, rich macropores, is conducive
