榛子是珍贵的油料树种,我省资源丰富。近年来,由于缺乏管理,致使榛林资源逐年减少,榛树生长衰退,病虫害严重,产量下降,因此,急需采取措施,加强对野生榛林的管理。我所经过连续5年的试验,对野生榛林进行垦复管理,单位面积产量增加两三倍,具体做法是: 1.选地及区划。野生榛林多分布在交通不便的近山丘陵区,应本着先易后难,由近及远的原则,逐步加以垦复。首先选盖度在80%以上,集中成片的阳坡或半阳坡榛林,为专业经营墓地,然后根据自然条件划为若干小区,每个小区面积2亩左右,小区之间留1米宽作业道。
Hazelnut is a precious oil tree species, rich in resources in our province. In recent years, owing to the lack of management, the resources of hazel forest have been reduced year by year, the growth of hazel trees has declined, pests and diseases have become serious, and the output has dropped. Therefore, measures are urgently needed to strengthen the management of wild hazel forest. After five consecutive years of experiments, I managed to reclaim the wild hazel forest and the yield per unit area increased two or three times. The specific measures are as follows: 1. Selection and zoning. Wild hazel forest are mostly distributed in hilly areas with inaccessible traffic and should be reclaimed step by step according to the principle of “easy first” and “hard late” and “near and far”. First select the coverage of more than 80%, concentrated into a piece of sunny or semi-sunny Hazel Lin, a professional business cemetery, and then divided according to the natural conditions of a number of district, each plot area of about 2 acres, between the district to stay 1 meter Wide work Road.
