| 摘 要： | 柱花草是世界热区重要的绿肥与牧草兼用的豆科作物。作为豆科绿肥，磷含量是影响绿肥品质的重要指标。本文对134份柱花草绿肥种质的磷含量进行了分析评价，结果表明，供试的134份柱花草绿肥种质有133份种质磷含量在0.3%以下，这些柱花草的磷含量达到四级有机肥磷含量标准，仅有1份柱花草种质的磷含量高于0.3%，其磷含量达到三级有机肥磷含量标准。

| Abstract: | Stylosanthes (Stylosanthes guianensias sw) is a leguminous crop used as green manure and forage in the tropical areas. Phosphorus content is one of the important indexes affecting the quality of green manure. The phosphorus contents in the green manure of 134 accessions of stylosanthes germplasm were analyzed and evaluated. The results indicated that 133 accessions out of the 134 accessions contained phosphorus of less than 0.3% and accounted for 99.3% of the whole germplasm, and that the phosphorus contents of these accessions conformed to the standard of phosphorus content listed in the Fourth Class Organic Manure. Only one accession of the stylosanthese germplasm contained phosphorus higher than 0.3%, and its phosphorus content conformed to the standard listed in the Third Class Organic Manure. |
