为了提高造林成活率,我们从1964年起,把起苗后不能及时栽植的马尾松、杉木、樟树等苗木的根浸在流水中,经试验取得了良好效果。实验证明,苗木浸根好处很多。第一,操作方便,省工;第二,能保持苗木湿润;第三,流水中溶于矿物质营养,可供根系吸收,增加重量,促进新生根发生,提高抗旱能力。如马尾松苗浸根16小时,一般可增加重量32.7%。
In order to improve the survival rate of afforestation, we start from 1964, after the seedlings can not be planted in time after the mass of Pinus massoniana, Chinese fir, camphor and other seedlings immersed in water, the test achieved good results. Experiments show that lotus root dipping lot of benefits. First, easy to operate, labor-saving; second, to keep the seedlings moist; Third, water soluble in mineral nutrients for root absorption, increase weight and promote the emergence of new roots and improve drought tolerance. Such as Masson pine seedlings immersed roots 16 hours, can generally increase the weight of 32.7%.
