摘要
采用黑膜覆盖进行杨树扦插育苗试验,结果表明,黑膜覆盖能够明显提高苗木质量,显著降低育苗成本。与常规育苗对照相比,黑膜覆盖苗高平均高出46cm,成活率提高8%,育苗成本节省53%。
Experiment on poplar seedling cultivation with black film covering demonstrated that it could improve greatly quality of the seedling and reduce the cost. Compared with the common seedlings cultivation, the seedling treated had 46 cm higher of height, 8% higher of survival rate and 53% less of cost.
