摘 要: | 在岚皋县对与作物间作和5种林下套种方式下的魔芋产量及病害发生情况进行了试验研究,结果表明,5种林下套种魔芋方式魔芋产量为14 025~18 619.5kg.hm-2,显著高于大田(玉米—魔芋)间作方式的产量10 830kg.hm-2(p<0.05),其中刺槐—魔芋、漆树—魔芋套种方式产量显著高于杜仲—魔芋、杉树—魔芋、板栗—魔芋等3种林下套种方式;5种林下套种方式魔芋发病率为1.63%~2.2%,分别极显著低于大田(玉米—魔芋)间作方式的10.4%(p<0.01),其中刺槐—魔芋套种方式魔芋发病最轻,极显著低于其他4种套种方式(p<0.01);刺槐林下种植魔芋具有发病轻、产量高、效益好等显著特点,值得推广。

Abstract: | With the increase of demand of konjac glucomannan and its products in China and abroad markets, konjac Soft rot disease and Sclerotium bligh haved restricted the development of konjac industry by long-term tillage. In order to effectively containment the disease, increase the income of mountainous farmers, the au- thor studied effect of intercropping pattern and woodland type on konjac disease and yield in Nangao count, put forward spatial planting techniques of locust-konjac on disease-resistant and high yield. |
