不同种植模式魔芋种芋经济效益比较

通过开展3种魔芋种芋的不同种植模式比较试验,探讨魔芋种芋产量及经济效益的关系。试验结果表明,林下间作模式植株健壮,产量最高,单位投入居中,产值最高,投产比最高。露地种植模式,随着密度增加,单芋质量和膨大系数呈下降的趋势,单位投入增大,单产增加,投产比差异缩小。相近密度的林下模式单芋质量和膨大系数相对较大,林下间作模式的魔芋种芋经济效益为最佳。

Effects of Three Different Planting Modes on Economic Benefit of Konjac

In the study, we studied the effects of three different planting patterns on yield and economic benefit of konjac production. The results showed that, in understory intercropping pattern, the konjac plants grew well, and had the highest yield, output value and input-output ratio, in addition, the per unit input cost was relatively lower. In open field planting pattern, as the planting density increased, both the weight of a single konjac and swelling coefficient showed downward trends, while the per unit yield and input cost increased, narrowing the gap of input-output ratio. Under the similar planting density, the sing weight of konjac and swelling coefficient were relatively larger in understory intercropping pattern, and konjac had the best economic benefit while was cultivated under the understory intercropping pattern.
