稳得高301活性生态肥肥效试验

Fertilizer Effects of Dynamic Ecological Fertilizer Wendegao 301

为探明稳得高 30 1活性生态肥在湖南旱地作物中的施用效果 ,2 0 0 1年用春马铃薯作材料进行了施用该肥的试验 .结果表明 ,稳得高 90 0 kg/ hm2 处理比等成本的丹麦复合肥 75 0 kg/ hm2 加磷肥 75 0 kg/ hm2 处理增产6 .2 1%,较不施化肥处理增产 11.5 8%.但稳得高 30 1对作物苗期生长供氮较低 ,故宜采用配施少量速效氮肥等相应措施 ,以充分发挥稳得高的肥效 .

Potatoes were used as the experimental materials to study the characteristics of Wendegao 301 and its application to the dry land crop of Hunan in 2001.The results show that the crop treated with 900 kg/hm 2 Wendegao 301 increases the output by 6.21% in comparison with that treated with 750 kg/hm 2 Danmark complex fertilizer plus 750 kg/hm 2 phosphorous fertilizer, both of which are of the same cost. It increases the output by 11.58% as compared with that without fertilizers.Wendegao 301 supplies a relatively low rate of nitrogen at the seedling stage, which suggests that small amount of N fertilizer should be used to make full use of Wendegao 301's nutritional effect.
