摘 要：
通过田间试验研究4种有机废弃物中的KEON(KCl可提取态氮)和PEON(磷酸缓冲液可提取态氮)2种形态的有机氮对菜用毛豆生长及化肥氮利用率的影响.结果表明:施用鸡粪和豆粕混合肥与单施化肥相比,地上部分干物质重分别提高20·4%和33·2%,籽粒中的蛋白质含量分别提高17·8%和16·2%,达到显著差异水平;与单施化肥相比,毛豆产量分别提高38·0%和32·5%.有机肥中的KEON和PEON与化学氮肥利用率呈正相关,其相关系数分别达到0·88和0·87(P<0·05).与单施化肥相比,施用鸡粪和豆粕混合肥的当季化学氮肥利用率可分别提高94·9%和67·4%.

摘 要：
Field experiment was carried out to study the effects of KEON (organic N extracted with KCl) and PEON (organic N extracted with phosphate buffer) from 4 kinds of organic wastes on the growth and N use efficiency of green soybean. The results show that the application of PM (poultry manures)could apparently improve the shoot dry weight, seed protein content and the yield by 20.4%, 17.8% and 38.0%, respectively, compared with regular chemical fertilizer applied. The application of OMM (organic mixed manures) could significantly improve the shoot dry weight, seed protein content and the yield by 33.2%, 16.2% and 32.5%, respectively, compared with regular chemical fertilizer applied. The positive correlation coefficiency between N use efficiency and KEON or PEON content was also observed with the correlation coefficient of 0.88 and 0.87 (P<0.05), respectively. Application of PM or OMM could greatly increase N use efficiency by 94.9% or 67.4% compared with regular chemical fertilizer applied.
