摘要
对17份四棱豆绿肥N、P、K、Ca、Mg、S、Fe、B、Mn、Cu、Zn、Mo、Cd、Cr、Hg、Pb、As营养元素含量进行分析评价。结果表明,四棱豆是含N、P、K高的优质绿肥,且中微量元素含量丰富,重金属含量低。根据综合评价,17份四棱豆均属于二级或三级有机肥。
Seventeen accessions of winged bean germplasm [Psophocarpus tetrogonolobus (Linnaeus) de Candolle] used as green manure were detected in terms of content of nutrient elements N, P, K, Ca, Mg, S, Fe, B, Mn, Cu, Zn, Mo, Cd, Cr, Hg, Pb and As. The result showed that the winged bean was a high quality green manure containing high N, P and K and fairly high meso-and micro-elements but low heavy metals. According to comprehensive evaluation, these 17 accessions of winged bean germplasm were evaluated comprehensively and categorized into the second or third class of organic manures.
