本文探讨了光萼猪屎豆(Crotalaria usaramoensis Baker.f.)在滇南热区的裁培及其利用。试验中系统地观测了光萼猪屎豆在滇南热区的生长发育特性和生物学产量以及利用情况。研究结果表明,光萼猪屎豆具有适应性广,生长快,产草量高,根瘤多以及产粒多,繁殖系数大等特点。它系一种具有多用途的优良绿肥作物,对培肥土壤,控制杂草生长均有明显的效果,是建立良好的热带农业生态系统的重要途径,是改革现行不合理的刀耕火种游耕制,实现合理轮作的有效措施,所以值得在滇南热区大力推广。
This article explored the cultivation and utilization of Crotalaria usaramoensis Baker. F. In the southern Yunnan hot zone. The experiment systematically observed the growth and development characteristics and biological yield of Calendula officinalis L. and its utilization in the southern Yunnan hot zone. The results showed that Cv. Shitake bean has wide adaptability, fast growth, high yield, nodules and more, more than the coefficient of multiplication. It is an excellent green manure crop with multi-purpose, which has obvious effect on fertilizing soil and controlling weed growth. It is an important way to establish a good tropical agro-ecosystem and is to reform the unreasonable slash-and- To achieve a reasonable rotation of effective measures, it is worth vigorously promote the hot zone in southern Yunnan.
