我们赵家店大队地处辽宁省康平县西北部,南面和西面与吉林省哲里木盟科尔沁后旗接壤。土壤主要为沙土和油沙土,年降雨量不足500毫米,蒸发量4,000毫米,春季西南旱风造成风剥沙压、打苗毁种,严重地威胁着农业生产。1955-1956年,大队开展了农田防护林网的营造工作,当时采用的树种以小叶杨实生苗为主。由于土壤瘠薄,特别是对林带缺乏应有的抚育管理措施,致使多年以来林带生长极为缓慢,形成了小老树,不能发挥预期的防护作用。1966年大队在党支部的领导下,成立了有干部、贫下中农和林土所防护林组同志参加的三结合林业科学实验小组,对生长缓慢的小叶杨林带进行了嫁接改造试验。嫁接后,经过8年,现在这条林带已长大成型,起到了良好的防止风沙危害的作用。
Our Zhaojiadian Battalion is located in the northwest of Kangping County in Liaoning Province, bordering with the Horqin Houqian of Zheli League in the south and west of Jilin Province. Soil is mainly sandy soil and oil sand, the annual rainfall of less than 500 mm, evaporation 4,000 mm, the wind caused by the spring southwest wind stripping sand pressure, seedling destroyed, a serious threat to agricultural production. From 1955 to 1956, the brigade started the construction of farmland shelterbelts. At that time, the tree species used were mainly Populus simonii seedlings. Due to the infertile soil, especially the lack of proper tending and management measures for the forest belt, the growth of the forest belt has been extremely slow for many years, forming a small old tree and can not exert the expected protective effect. In 1966, under the leadership of the party branch, the brigade set up a three-pronged forestry science experimental group with cadres, poor peasants and poor forests, and comrades from the forest-earth shelterbelt group to carry out experiments on the grafting transformation of the slow-growing poplar grove. After grafting, after 8 years, now this forest belt has grown into a shape that has played a good role in preventing wind and sand damage.
