幼龄胶园间作台农16号菠萝研究初报

Study on young rubber/Tainong NO.16 pineapple intercropping pattern

以幼龄胶树(≤4年)和台农16号菠萝为试材,建立幼龄胶园—台农16号菠萝间作模式并进行相关研究。结果表明:该模式下,菠萝生长发育正常,果品质量略有降低,但未达显著水平;而幼龄胶树在试验期内树围和株高累计增加量较对照分别增加12.57%、9.34%,调查的4种重要病虫害中有3种危害有所减缓。该模式不仅增加了种植者经济收入,还能合理利用资源、避免土壤板结、促进胶树早产,综合效益显著。

Taking young rubber plantation （≤4 a） and Tainong NO.16 pineapple as experimental materials, one kind of intercropping pattern was established and series of related comparative experiments were carried out. The results showed that, under this pattern, the pineapple were able to grow and develop normally, and the fruit quality of Tainong NO.16 pineapple slightly declined, without a significant difference. On the other hand, there was not any negative effect for the rubber＇s growth and development, and contrarily, the cumulative increment of stem girth and length were higher than the control, with proportions of 112.57% and 109.34% of the control respectively. And the injury of 3 （4 in total） kinds of diseases and pests were remarkably lessened. Simultaneously, the model had not only brought planters a much higher income, but made the environmental resources rationally utilized, avoided the soil hardening and promoted the earlier production of rubber. In short ,this model showed a great prominent comprehensive benefit.
