针对当前白皮松在育苗过程中育苗基质必须混配森林土而造成生产成本高的状况,试验完全以大田土为基质来培育白皮松。分析了白皮松的分布情况及形态特征,根据实际情况进行试验设计,选取试验地点、试验材料、试验时间,并描述了具体的试验步骤。试验结果表明,大田土培育的白皮松幼苗长势健壮且可以节约生产成本。
In view of the current high production cost caused by the fact that Pinus bungeana seedling substrate must be mixed with forest soil in the course of nursery, the experiment is based on the field soil as substrate to cultivate Pinus bungeana. The distribution and morphological characteristics of Pinus bungeana were analyzed. The experimental design was carried out according to the actual situation. The test sites, test materials and test time were selected and the specific test steps were described. The results showed that the seedlings of Pinus bungeana nurtured in Daejeon soil grew robust and could save the cost of production.
