- 摘要:
- 通过对新修梯田不同部位土壤理化性质研究，发现切土和填土部位有显著差异，对作物产量产生很大的影响。填土部位物理性质好，养分含量高，作物产量高，但保墒能力差；切土部位物理性质较差，底土非常黏重，养分贫乏，造成作物的减产。建议在修筑水平梯田时针对两部位的差异采取措施，以充分发挥梯田的效益。
- Abstract:
- Through the study on the physiochemical properties of different pionts of newly-built terrace, it is discovered that digging and filling points has remarkable difference, having tremendous influence on the crop yield. The filling points’ physical properties is good, the soil nutrient is high, the crop yield is high, but preservation ability of soil moisture is bad; Digging points’ physical properties is worse, the subsoil extremely sticks heavily, the nutrient is deficient, causing the reduction of crop. The suggestion is to take different measures at different points on terrace while constructing terrace so as to give its full play.
