去年以来,廊坊市安次区为改善林木资源现状,大力推广杨树伐根嫁接技术,创出一条在干旱少雨条件下,杨树抗灾、速生、丰产的好途径。 1999年安次区被列入《河北省杨树蛀干害虫工程治理区》后,组建了一支由28人组成的嫁接技术服务队,着手调整该区的林业资源结构,引入伐根嫁接技术。同时按照项目治理工程的有关要求,对被害杨树进行人工防治和化学防治,对虫株率大于35%以上的毛白杨、中林46等虫害木进行更新,伐根嫁接优良苗木。并于当年春季在万庄镇大伍龙三村搞了500亩的伐根嫁接,成活率在85%以上。但由于苗木管护不及时、措施不到位,责任制不落实,致使农民对造林成活的分成比例缺乏信心,责任感不强,存活率
Since last year, in order to improve the status quo of forest resources, Anci district of Langfang City has vigorously popularized the poplar grafting technology and created a good way for the poplar trees to resist disaster, grow fast and produce high yield in the condition of arid and rainy days. In 1999, Anci district was listed as Hebei poplar stem borer project management area, and a 28-member grafting technical service team was set up to adjust the forestry resource structure in this area and introduce the technology of cutting-root grafting . At the same time, in accordance with the relevant requirements of the project management project, the poplar tree for the prevention and control of man-made damage, insect population greater than 35% of Populus tomentosa, Zhonglin 46 pests such as wood to be updated, cutting root grafting excellent seedlings. And in the spring of that year, Wuzhong Township, Wulong three village engaged in 500 acres of cutting the root grafting survival rate of 85%. However, due to inadequate nursery and timber management and management, the measures are not in place and the responsibility system is not implemented, resulting in a lack of confidence and responsibility among farmers in the proportion of afforestation survival, and the survival rate
