广西喀斯特石山区木豆种植适应性试验

本文报道木豆在广西西部喀斯特地区适应性试验结果。结果表明,木豆适应性强,速生快长,当年种植株高可达1.5~3.0m,能较快覆盖裸露的喀斯特石山,且可涵养水源,防止水土流失,提高土壤肥力,恢复生态环境。木豆籽粒可做人类粮食,也可作为畜禽饲料,木豆的嫩枝叶可做山羊、水牛、黄牛等草食动物的青饲料。因此,木豆是解决桂西石山区畜牧饲料的最好作物之一。

An adaptive test of pigeonpea on karst area in Guangxi

The adaptive test of pigeonpea planted on karst area of Guangxi was investigated. The results showed that the pigeonpea was highly adaptive and fast growing, the plant height reached 1.5~3.0 meters planted in the first year and covered the exposed karst area. Pigeonpea can conserve water resources, protect against water loss and soil erosion, improve soil fertility and recover ecological environment on this area. Its seeds can be used as grain for human and as forage for fowls and livestock. And the tender shoots and leaves can be used as fresh forage for goat, buffalo, cattle and so on. Pigeonpea is one of the best crops used as forage for animal husbandry in karst area in Guangxi.
