在临夏刘家峡库区沿岸四县5年生花椒园间作黄芪(Astragalus membranacens),结果表明,每年每667m~2椒园间作黄芪可控制土壤流失量5.85kg,3~4a可控制土壤流失量17.55~23.40kg,较椒园间作小麦、油菜、豌豆等夏季作物的传统经营模式减少土壤流失量17.55~23.40kg,相当于3~4a减少水库淤泥17.55~23.40kg。年花椒、黄芪纯收益1 443元,生态经济效益十分显著,并总结出了椒园间作黄芪技术措施。
Astragalus membranacens was inter-planted in five-year-old peppers orchards in the four counties of Linxiaxia reservoir area. The results showed that Astragalus membranaceus could control 5.85kg of soil loss every year between 667m ~ 2 and between 17.55 and 23.40 kg. Compared with the traditional management mode of summer crops such as wheat, rape and pea, the reduction of soil loss by 17.55 ~ 23.40kg, equivalent to 3-4 days, reduces the reservoir sludge by 17.55 ~ 23.40kg. Year pepper, astragalus net profit of 1 443 yuan, the ecological and economic benefits are significant, and summed up the intercropping Astragalus Pepper Technology measures.
