相较砌石墙、垒土坎的旱地梯化技术,植物篱逐步梯化具明显省时、省工、省资的优点。１９９１年以来贵州省农科院参加的亚洲旱地坡地协作网试验证明,该技术有较好的水土保持效果,保肥能力强,配合合理施肥技术可将坡耕地逐步梯化并改良培肥,达到持续利用目的,特别适宜于在土山、易风化岩山或上层较厚的石质山区示范推广。
Compared with masonry walls, barrier ridge dry up the ladder technology, hedgerows step by step with significant time-saving, labor-saving, provincial capital advantages.
