针对农牧交错区的林牧矛盾以及放牧牲畜对幼树的踩踏啃食等问题,本文介绍了一种网套保护幼树的新方法,并通过对比试验,研究了该方法的使用效果。结果表明,与对照相比,幼树保护网套的使用使幼树被啃食率降低了87.8%,而其保存率则提高了37.3%,虽然造林总成本提高了353.3元/hm2,但有效地保护了幼树免于动物的伤害,对提高农牧交错区的造林成效和促进林分更新发育具有重要作用。
In view of the conflict between forestry and livestock husbandry in the ecotone between agriculture and animal husbandry and the problem of grazing livestock stampeding grazing on the sapling, this paper introduces a new method to protect young saplings. Through comparative experiments, the effect of this method is studied. The results showed that compared with the control, the use of sapling nets reduced the grazing rate of young saplings by 87.8%, while the conservation rate increased by 37.3%. Although the total cost of afforestation increased by 353.3 yuan / hm2, it was effective Protect the saplings from animal injuries and play an important role in improving the afforestation effectiveness and promoting the regeneration of the stands in the ecotone of agriculture and animal husbandry.
