固海扬水新灌区是中宁县以林为主的新开发区。但由于冬春野兔啃食幼树树皮,常造成树木生长不良甚至死亡。据调查,未采用任何保护措施的幼树,经一个冬春,有79.3％被野兔啃食,其中,因啃食而死亡占53％。我们于84年11月下旬,用猪油涂干的办法进行试验,并用群众惯用的白灰涂干和不采取保护措施作对照。猪油经切碎,熬炼即可直接涂刷。白灰过筛、溶水加入胶水、食盐,搅拌均匀,然后涂干50厘米高,整个冬春季只涂刷一次,85年5月20日进行效益调查,结果涂刷猪油的树木未遭危害,涂白灰的有41.9％受害,其中死亡的占23.1％,对照受
Guhai Yangshui new irrigated area is Zhongning County forest-based new development zone. However, due to the winter and spring hares grazing saplings, trees often cause poor growth or even death. According to the survey, saplings without any protective measures were grazed by hares after 79.3% of the winter and spring seasons, of which 53% died of grazing. In late November of 1984, we experimented with a lard-dried solution and compared it with the usual white ash and without protective measures. Lard chopped, refining can be directly brushing. Lime sieving, water to join the glue, salt, stir, and then dried to a height of 50 cm, brushing the entire spring and winter only once, on May 20, 85 for benefit investigation, the results of brushing lard trees are not endangered, 41.9% of the ashes were affected, of which 23.1% were fatal, compared with controls
