1、利用。通過對成熟期主要評價指標(biāo)進(jìn)行主成分分析及聚類，18個綠豆品種可劃分為5類。第1類包括C2032、C0998和C1271，具有高生物量、產(chǎn)量及養(yǎng)分累積量，低C／N，低耐蔭性，可摘莢后翻壓，但不適于間套作種植。第1I類包括C0827、C0003等11個品種，各性狀值均較優(yōu)，具有較高的綠肥利用價值。第Ⅲ類僅包含C3821一個品種，各性狀表現(xiàn)均較差，不適合用作綠肥。第Ⅳ類僅包括晉綠豆l號，該品種除植株鉀累積量較高外，其余指標(biāo)表現(xiàn)均較差。第V類包括冀綠7號、冀綠8號兩個品種，具有較低的生物量、產(chǎn)量及養(yǎng)分累積量，但耐蔭性較優(yōu)，適用于間套作或填閑種植，更適合作為糧食作物。關(guān)鍵詞：綠豆，綠肥
