Ridge cultivation is not easy to harden, which is especially beneficial to the growth of crop roots. 2. After the ridge cultivation method is adopted, the surface area of the ground increases by about 20%-30% compared with the usual flat cropping, which increases the light-receiving area of the soil and dissipates heat. , The heat absorption is very fast, which is very conducive to the accumulation of photosynthetic products. 3. The position of the ridge and the ridge is very different. If it rains heavily, it is required to facilitate drainage and waterlogging prevention. Irrigation along the furrow to avoid drought. Especially when planting horse bell tombs, sweet potatoes and other crops, the soil water content of ridge farming is less than that of flat farming, which is conducive to the expansion of good blocks. 4. Due to the existence of ridges and platforms, it can block wind and reduce wind speed; It will fall into adjacent furrows without being blown away along the surface, reducing wind erosion of the soil.
