新疆干旱区木豆引种适应性研究

对我国西南地区木豆品种进行了引种栽培试验,首次研究木豆在新疆干旱区栽培的适应性.获得了各木豆品种在新疆干旱区的物候期及生长规律,测定了各品种生物产量和鲜枝叶营养成分.栽培试验获得较高的鲜枝叶产量,木豆鲜叶的蛋白质和粗纤维含量较高.但各木豆品种均不能完成生育期,无法获得成熟果实,不能越冬.

Adaptability of Pigeon Pea(Cajanus cajan)Introduced in the Arid Areas of Xinjiang

The adaptability of pigeon pea cultivars introduced in the arid areas of Xinjiang from the southwest of China was studied to obtain their phenological periods,the growth rules,the biomasses and the nutrients in fresh branches and leaves in this paper.The results showed that the high yields of fresh branches and leaves and the high contents of proteins and crude fibers in the fresh leaves of all introduced cultivars could be obtained in the experiment.But all pigeon pea cultivars were unable to complete their growth periods,bear mature fruits and live through the winter.The high-yield techniques,the exploitation of the feeding value and the ecological benefits of pigeon pea in the arid areas of Xinjiang were needed to be further studied.
