海藻酸增效剂及含海藻酸增效尿素的制备和应用

Preparation and Application of Alginate Synergist and Synergistic Urea Containing Alginate

简要介绍了海藻酸增效剂和含海藻酸增效尿素的制备方法、主要技术指标和作用机理。为验证含海藻酸增效尿素抑制氨挥发和对玉米的增产作用,开展了试验研究,设置了不施肥、施普通尿素和施含海藻酸增效尿素等3个处理。结果表明:与施普通尿素处理相比,施含海藻酸增效尿素处理的35 d累计氨挥发量下降41.77%;施含海藻酸增效尿素处理的玉米产量比施普通尿素处理的增产11.49%。施含海藻酸增效尿素可改善土壤生态环境,具有明显的经济效益。

A brief introduction is made of the preparation method,main technical specification and mechanism of action of alginate synergist and synergistic urea containing alginate.In order to verify the effect of synergistic urea containing alginate on inhibiting ammonia volatilization and increasing maize yield,experimental research is carried out,and three treatments are set,including no fertilization treatment,application of ordinary urea treatment and application of synergistic urea containing alginate treatment.The results show that compared with ordinary urea treatment,the cumulative ammonia volatilization of synergistic urea containing alginate treatment in 35 days decreases by 41.77%.The yield of maize treated with synergistic urea containing alginate is 11.49%higher than that treated with ordinary urea.Applying synergistic urea containing alginate can improve the soil ecological environment and has significant economic benefits.
