植物篱笆与金属护栏网在果园防护中的应用效果

经济林童期相对较长,前期经济收益较低,因此提高综合收益,降低前期管护成本是目前生产中急需解决的主要问题之一。为了降低经济林前期投入成本,提高经济收益,文中对枳和花椒两种植物篱笆与设施工程中常用的金属护栏网这3种防护措施的造价、维护费用、防护效果和经济收益进行了调查和比较分析。结果表明:植物篱笆中,花椒篱笆的经济收入最高,达到7.88元/m,而枳篱笆的防护效果较好,其经济收益较高,可达到7.00元/m;但是,植物篱笆的前期防护效果较差。而金属护栏网的造价和维护费用均最高,可达6.67元/m,但建置后即可起到防护作用,前期防护效果较好。文中综合分析认为,植物篱笆适合童期较长的经济林树种,而金属护栏网则适用于城镇近郊农业观光园、果树采摘园和经济价值不高的育苗基地,若将植物篱笆和金属护栏网结合起来使用,则可兼顾长短期效益,值得在生产中推广应用。

Application effects of plant fence and metal net fence in orchard protection

The one of the key questions in present industry of nonwood forest is lower beneift at the early stage because of the longer juvenile phase. In order to reduce the costs and to increase the beneift at early stage, the differences among cost, protecting effect and economic income of the three type methods were researched, including two plant fences and one metal net fence. The results showed that in the two plant fences, theZanthoxylum bungeanum fence had higher economic income and the beneift reached 7.88 Yuan per meter, but thePoncirus trifoliatefence had better protecting effect and higher beneift, which reached 7.00 Yuan per meter. Compared with the plant fences, the metal net fence had the highest cost and it reached 6.67 Yuan per meter, but the metal net fence had better protecting effect at earlier stage. In view of the results, the plant fences was suit for the nonwood forest species with longer juvenile, but metal net fence was suit for agricultural sightseeing orchards which were closely city, fruit picking orchards and lower beneift nurseries. Moreover, the long and short term beneifts would be the highest if the plant fences were associated with metal net fence, and the method was worth popularizing and applying in production.
