摘要
研究保水剂对沙性土壤的保水效果和对沙土理化性质的影响,在人工气候箱中,观察了保水剂用量对沙土的保水性能和对沙土的改良作用的影响,结果表明,随着保水剂用量的增加,沙土含水量和电导率均先出现增加后减小的趋势,沙土的团聚体含量逐渐增大,沙土的容重却逐渐减小,而保水剂含量对沙土的p H影响不大,不会影响植物生长。
The effect of water retention agent against the of soil were studied. The water retention agent dosage on soil water retention and physicochemical property sandy soil water retention performance and the improvement of sand had been studied in the artificial clima.te box. The results showed that with the increase of dosage of water retention agent, the sandy soil water content and electric conductivity decreases after first increased, the sand aggregate content increased gradually, however, the sandy soil bulk density is gradually reduced, and the influence of the pH value of the water retention agent content on the sand could not affect the growth of plants.
