等高植物篱模式就是在坡耕地上每隔4~8m的距离沿等高线将植物篱与作物种植带相间分布的一种农林复合经营模式,用于坡耕地的水土保持。已有的研究结果表明,等高植物篱技术用于坡耕地可有效地改善土壤物理性质和土壤水分状况,防治坡耕地水土流失效果显著,土壤水分的季节性再分配也有利于农作物的生长。但是该系统内植物篱和农作物相互之间的水分和养分关系有待深入研究。
Contour hedgerow pattern is an agroforestry management model in which hedgerows and crop belt are distributed along contours every 4 ~ 8m along sloping land for soil and water conservation of sloping land. The existing research results show that contour hedgerows technology can effectively improve soil physical properties and soil moisture condition in sloping fields, and has significant effects in preventing and controlling soil erosion in sloping fields. Seasonal redistribution of soil moisture is also beneficial to the growth of crops. However, the relationship between plant hedgerows and crop moisture and nutrients in this system needs to be further studied.
