抚育保护是造林六项基本措施之一。俗话说:儿不抚育不成人,树不抚育不成林。事实证明,凡经过抚育的幼林,在成活和生长发育方面,都较未抚育的有显著的不同。如乌盟察右前旗乌拉哈乌拉公社联丰管理区,1959年春季造的杨树林,由于经过精心抚育,幼林生长茁壮,成活率达100%;昭盟赤峰市前进人民公社,1956年在新造450亩杨树林地内,采用农林间作抚育幼林,不仅收入了粮食,幼林当年生长高即达120厘米,成活率达90％,已经郁闭成林。但在同一时期,同一地点造的林,而未经过扶育的,当年才生长50厘米左右,且枯黄瘦小,成活率不足60％。加强幼林抚育管理,是实现林木速生丰产的重要途径,通过抚育管理,除掉与
Nurturing protection is one of the six basic measures for afforestation. As the saying goes: children do not nurture an adult, the tree does not foster no forest. Facts have proved that where the young forest after being nurtured, both in terms of survival and growth are significantly different from those not nurtured. For example, Wu Shouqian right before the flag Wulahala commune Lianfeng management area, made in the spring of 1959, Yang Shulin, due to carefully nurtured young trees to grow and survive, the survival rate of 100%; Chuxiong forward Chifeng City Commune, in 1956 in the new 450 Mu poplar woodland, intercropping agriculture and forestry with young forest, not only the income of food, young forest that year up to 120 cm high, the survival rate of 90%, has closed forest. However, in the same period, forests made in the same place, without being nurtured, grew to about 50 cm in the same year and were thin and yellow with a survival rate of less than 60%. Strengthening the management of young forest tending is an important way to realize the fast-growing and yield-rich forest. By tending management,
