通过几种农业保水(抗旱)剂对江淮丘陵地区玉米的节水及提高肥料利用率进行田间应用研究。结果表明,施用土壤保水剂(苗乐宝)、抗旱保水剂(旱地龙)玉米增产7.6%、6.4%;氮吸收量提高7.6%、5.1%;磷吸收量提高13.2%、8.7%。节水效果显著。 Through several agricultural water conservation (drought) agents on the Jianghuai hilly areas of corn water and improve fertilizer utilization in field applications. The results showed that the corn yield increased by 7.6% and 6.4%, respectively. The nitrogen uptake increased by 7.6% and 5.1%, while the phosphorus uptake increased by 13.2% and 8.7% respectively. Water saving effect is remarkable.
