滦县是我省板栗重点产区之一,具有悠久的栽培历史。近三十年来,由于连年遭到破坏性砍伐,损失极为严重。总株数由解放初期的70,000株下降到1983年的26,589株。而且多年失管,虫害成灾,致使树势衰弱,产量低而不稳。再则由于栗树屏障的不断被毁,破坏了防护体系,风沙危害对农作物构成了严重威胁,造成农业产量低而不稳的连锁性灾害,为了更新复壮砂地板栗。1984年,我们与省果树所协作,以板栗主要产区的孟家屯村作基点,以商家林乡为联系面开展了 Luanxian County, one of the key producing areas of chestnut in our province, has a long history of cultivation. In the last three decades, the losses have been extremely serious due to the destructive deforestation year after year. The total number of plants decreased from 70,000 in the early liberation period to 26,589 in 1983. And many years of tube loss, pests disaster, resulting in frail weakness, low yield and instability. In addition, because of the continuous destruction of the chestnut tree barrier, the protection system has been destroyed. The hazards of sandstorm have posed a serious threat to the crops and have caused the chain disasters of low and unstable agricultural output in order to renew the chestnuts of rejuvenated sand. In 1984, we collaborate with the provincial fruit trees to Mengjiatun village, the main producing area of ​​chestnut as the starting point, and the commercial forest and township as the contact surface
