我场虎沟工区是新建的隔年核桃生产基地,近年来松鼠危害严重。去年已挂果的十一亩种子园收种不足十斤,有的成年母树测产可收十五、六斤,在即将成熟的数日之内,全被松鼠拉光。今春育苗0.5亩,种子又被盗食,一苗未出。因此,防治松鼠成了保证种子园安全的紧迫任务。 I HUGO work area is the new walnut production base in the next year, squirrels in recent years a serious harm. Last year, 11 acres of fruit-bearing seed orchard planting less than ten pounds, and some adult trees measured yield can receive fifteen, six pounds, within a few days to maturity, all squirrels pull light. 0.5 acres of seedlings this spring, the seeds have been stolen food, a seedling is not out. Therefore, the prevention and control of squirrels has become an urgent task to ensure the safety of the seed orchard.
