直播造林技术简单,投资低,操作方便,收效快,是一种简单宜行的造林方法。但由于受到自然灾害的影响,立地条件所制约,未能大面积应用。我区一九八五年直播油松6500余亩,山区也多次进行过;均因鸟兽危害严重、气候干旱等原因而均以失败告终。一九八三年我们采用了塑料薄膜钟形罩直播造林法,获得了较好的效果;为大面积推广直播造林找到了理想的途径.
Live afforestation technology is simple, low investment, easy operation, fast results, is a simple method of afforestation. However, due to the impact of natural disasters, site conditions restrict the application of large area. Lively broadcast 6500 acres of pine in our area in 1985, the mountainous area has also been carried out many times; both due to serious damage to birds and animals, climate and drought and other reasons have failed. In 1983, we adopted the direct seeding method of plastic film bell to obtain good results and found an ideal way for large-scale popularization of afforestation by afforestation.
