摘要
黑龙江省西部地区是我省农牧业生产的重要基地,盐碱土占该区面积2.1%。由于盐碱土的物理化和化学性质相对比较恶劣,土壤粘重,表层下有碱化层,含盐量和碱化度高,对树木生长影响较大,给该地区林业发展带来了很大难分难解度。为了降低盐碱土对树木生长的危害,研制了一种即能降盐碱土的含盐量和碱化度又能增加土壤怕肥力的调理剂。3年的试验证明调理剂施入土壤后,能够降低盐碱土的含盐量和碱化度,提高了造林成活率和保存率及树木生长率,试验达到了预期效果。
The west area province is the important agriculture and animal husbandry production base of Heilongjiang province. The saline - alkali soil area accounts for 2.1% of all the area. The saline - alkali soil is viscidity and heavy with high salinity and exchangeable sodium percentage, which can affect the tree growth seriously. This paper introduce an amendment that can reduce the salinity and exchangeable sodium percentage and increase soil fertility. The 3 years experiment result showed that it can also improve survival rate and growth rata.
