摘要
通过在黑龙江省宾县退耕还林区中应用保水剂的试验研究,结果表明:应用保水剂使4年生樟子松造林保存率平均比对照提高8个百分点,土壤含水量比对照提高23.8%,高生长平均比对照提高11 cm。在退耕还林重点区域应用保水剂,可有效地节省人力和物力。
Through the experiments by using aquasorb （sodium polymer） in the region of retumlng farmland to forestation in Binxian county in Heilongjiang Prov. , the results show that the planting preserving rate of 4-year-old Pinus sflvestris var. mongolica is by 8% higher than the control. The soil moisture content is by 23.8% higher than the control. Lots of labors and material resources can be saved through using aquasorb in the key region of returning farmland to forestation.
