该文介绍了两种田间集雨措施(渐进式等高梯田和坡地等高沟垄种植)的集雨增墒效应和增产作用。试验表明:在小雨、中雨、大雨和长期少雨的条件下,两种措施下的土壤水分含量均明显高于对照;但如果一场大雨之后接着又来一场大雨,则两种措施的集雨增墒效果就不太明显了。这两种措施的增产作用也很大:渐进式等高梯田可增产19.4%~25.5%,坡地等高沟垄种植可增产34.1%~51.7%。
This article describes the effects of rainwater harvesting and yield increase on two sets of field rain harvesting measures (such as steppe terraced and hillside ridge planting). The results showed that the soil moisture content of the two measures were significantly higher than that of the control under the conditions of light rain, moderate rain, heavy rain and prolonged dry weather. However, if a heavy rain followed another heavy rain, the two measures Rain is not obvious effect of increasing moisture. The stimulation of these two measures is also very significant. The incremental terraced fields can increase 19.4% ~ 25.5% and the planting of high ridge and ridge on the slope can increase 34.1% ~ 51.7%.
