多年来,为提高造林成活率和保存率,人们根据干旱地区的特点不断改进造林方法,先后总结出了改春季造林为春、夏、秋三季造林,截(?)造林和钻孔深栽等措施,取得了一定成效。为进一步研究和探索提高成活率的途径,我们于1983—1986年先后在宁夏同心县马高庄乡、郭家大湾林杨、羊路乡甘草掌村、骆驼腰岘村进行了秋植幼树埋土越冬试验、推广和调查工作,取得了较好的效果。试验结果表明,秋植刺槐、白榆埋土越冬后比常规造林(不埋
Over the years, in order to improve the survival rate and preservation rate of afforestation, people constantly improve the afforestation method according to the characteristics of arid areas, and successively summed up the afforestation in spring for the spring, summer and autumn, reforestation and deep bored planting Measures, and achieved some success. In order to further explore and explore ways to improve the survival rate, we conducted autumn planting plants in Maogangzhuang Township, Guoxiandaowan, Yangcao Township, Lichecao Village, Yangluo Township, Tree buried overwintering test, promotion and investigation, and achieved good results. Test results show that autumn planting acacia, white elm buried later than the conventional afforestation (not buried
