采取农业生产中的等高耕种、等高带状间作、深耕垄作区田等技术措施,可以消除或削弱水土流失的因素,增强土壤的抗冲能力,从而达到保持水土、增加产量的目的。这些措施适于在一时不能修梯田或者坡度较小的坡耕地上使用。等高耕种:在坡耕地上,沿等高线且垂直于斜坡走向进行横向打垄耕作。它以垄沟和垄合阻滞径流,减少水土流失。等高耕种最好在秋翻地时打垄,以利于土壤保墒。为了避免坡面径流紊乱而下,打垄时应安排好水路和道路。进行打垄作业时,应用回转犁向下方翻土,以逐步减缓坡度。等高耕种的头几年,最 Adopting technical measures such as contour cultivation in agro-production, contour strip intercropping and deep furrow cultivation in fields can eliminate or weaken the factors of soil erosion and enhance the soil’s anti-erosion ability so as to maintain soil and water and increase production. These measures are suitable for temporary use on sloping fields where the terraces can not be repaired or where the slope is slighter. Contour cultivation: In sloping fields, horizontal tilling is carried out along contours and perpendicular to the slope. It uses runoffs and dams to stop runoff and reduce soil erosion. The best tillage in the autumn turn land ridge, in order to benefit the soil moisture. In order to avoid disorderly runoff slope, playing ridge and water should be arranged when the road. When drilling a ridge, use a rotary plow to turn the soil down to gradually reduce the slope. The first few years of farming, the most
