摘要：

为探明中国南方蓼科绿肥的肥用价值,分析了22份采于海南等地蓼科绿肥种质的养分含量,并对其进行有机肥分级.结果表明:蓼科绿肥的大量元素含量变异较大,其平均含氮、磷、钾的量分别为2.10%,1.63%,2.19%.22份蓼科绿肥种质均为一级或者二级有机肥,是品质较高的有机肥.

Abstract:

In order to illustrate the organic manure quality of Polygonaceae green manure in the south of China, the Polygonaceae green manures of 22 germplasms were collected from the tropics such as Hainan and the organic manure quality was evaluated based on the analysis of the nutrient content. The results indicated that the macro nutrient contents of 22 Polygonaceae germplasms varied substantially. The mean values of nitrogen, phosphorus, and potassium contents were 2.10%, 1.63% and 2.19%, respectively. All tested accessions of Polygonaceae plant germplasms had high quality when used as GM. The most of Polygonaceae GMs were categorized into the first-class and secondary organic manures.

Key words: Polygonaceae green manure, Nutrients content, Classification and evaluation, Tropics &, subtropics
