【摘要】 将保水剂,有机、无机营养元素等材料和复合肥通过特殊工艺制成抗旱复合肥。通过玉米盆栽试验,在控制水分条件下,对抗旱复合肥的节水节肥性能进行研究。结果表明抗旱复合肥能显著提高盆栽玉米生物量,水分利用率和氮素利用率;与普通复合肥相比,玉米干重增幅为14.8%～27.2%,WUE增幅为39.6%～61.3%,氮素利用率增幅24.5%～45.2%。更多还原

【Abstract】 Anti-drought fertilizer(ADF) can be made by adding some kinds of Organic and inorganic nutrient element etc and chemical fertilizers into super absorbent polymer by special techniques.The pot experiment on Maize was carried out to investigate water-retaining and fertilizer use effects of ADF under water-controlled conditions.The result showed that the ADF applied could improve the Maize plant yield significantly,water use efficiency and N element use efficiency.Compared to applying ordinary fertilizer,the Maize plant yield was increased by 14.8%～27.2%,48.4%～68.8% in the water use efficiency,24.5%～45.2% in N element use efficiency by applying anti-drought fertilizers.更多还原
