摘要
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。
The hedgerow cropping techology integrated with the gradually terraced land is advanced in saving time,labour and fund,comparison with the traditional technology of making stone or soil wall for terracing slopeland. Since 1991 Guizhou Academy of Agricultural Sciences became the member of the Asia Sloping Land Net-work and the experiments conducted in Guizhou showed that it had a better effect of controlling soil loss andrunoff, holding soil fertility. Accompanied with rational application of fertilizers the sloping land will be notonly gradually terraced,but also soil fertility increased,and then the goal of sustaining land use reached.It issuitable for extension in the areas of soil hills, easily weathering rock hills or the stone mountainous areaswith deep soil later.
