伴生种植皱叶黑膏桐对美藤果植株生长和结实的影响

Effects of Planting Associated Wrinkled-Leaf Jatropha on the Growth and Fruiting of Inca Peanut

摘要: 2012~2015期间，在云南西双版纳和元江那唐山南亚热带高档油料植物试验基地，我们开展了皱叶黑膏桐与美藤果(Inca Peanut)伴生种植的试验。本项试验的目旨在利用膏桐活体根系释放的挥发性化感物质对实验区土壤有害生物进行实时生物防控，以保证美藤果植株健康地生长、开花和结果，实现美藤果引种开发的优质高产。试验结果表明，采用皱叶黑膏桐伴生种植以后，在美藤果种植试验区内线虫、白蚁和病原微生物的危害已明显低于美藤果单一种植区。与此同时在伴生种植区内，美藤果植株生长速率、分枝数量、开花结果物候，雌花比例、坐果率等指标，也得到了明显提高。

Abstract: During 2012-2015 years, new Jatropha varieties and Inca peanut planting collocation experiment had been conducted on the south subtropical high-grade oil planting test bases of Xishuangbanna and Yuanjiang. This study aimed at using volatile components released by the living roots of Ja-tropha curcas to prevent or/and control nematode, termites and other soil pests, to guarantee healthy growth, flowering and fruiting of Inca peanut plants, and to realize high yield and good quality of Inca peanut production. Experimental results show that after Inca peanut accompanied planting with wrinkled-leaf jatropha, in the planting test area the nematode and termite’s dangers had been greatly lower than those of Inca peanut monoplanting. At the same time, the indicators such as plant growth rate, number of branches, phenology of flowering and fruiting, the proportion of female flowers, fruit setting rate, have also been significantly improved.
