在试验室稳定蒸发条件下测试了ＤＱ－１型保墒剂在黑龙江省西部风沙土中的保墒性能。结果表明，ＤＱ－１型保墒剂可在一定程度上增加土壤持水性能并增加土壤有效持水量。在风沙土中该保墒剂施用量得当可明显增强风沙土的保墒性能；其最佳保墒阶段在该土壤中为重量含水量的１０％～２０％。ＤＱ－１型保墒剂在风沙土中施用量在５．０‰左右表现出最好的保墒效果。
The moisture retention performance of DQ-1 type moisture preservative in aeolian sandy soil in the west of Heilongjiang Province was tested under the condition of stable evaporation in laboratory. The results showed that DQ-1 preservative could increase the soil water holding capacity and increase the effective water holding capacity of soil. In the aeolian sandy soil, proper application amount of the preservative can obviously enhance the soil moisture conservation performance of the aeolian sandy soil. The optimal stage of soil moisture conservation is 10% ~ 20% of the water content in the soil. DQ-1 type of moisture preservative in sandy soil application rate of about 5.0 ‰ showed the best effect of preserving soil moisture.
