本试验研究PAMN保水剂对沟坝地冬小麦和山坡地苹果园土壤含水率的影响。结果表明:沟坝地冬小麦施保水剂后保水效果从上到下依次递减,以0～20cm土层保水效果最好,比对照提高19.77％,山坡地苹果园施保水剂处理以根系集中分布区效果最佳。
This study was to investigate the effect of PAMN super absorbent polymer on soil moisture content of winter wheat and apple orchard on hillside. The results showed that the water retention efficiency of winter wheat Shubao agent decreased gradually from the top to the bottom, and the water retention effect of 0-20 cm soil layer was the best, 19.77% higher than that of the control. Best effect.
