2、高于低氮處理的;在生殖生長階段,高磷處理植株的始花期和始莢期都比低磷處理的早,且每花序結(jié)莢數(shù)比低磷小區(qū)多。3個扁豆品種之間前期產(chǎn)量存在顯著差異,而其他因素處理的前期產(chǎn)量都未達(dá)到顯著水平。氮肥促進扁豆的營養(yǎng)生長,磷肥促進扁豆的生殖生長。不同施肥水平對扁豆品種前期產(chǎn)量沒有影響。關(guān)鍵詞施肥水平;扁豆;生長發(fā)育;前期產(chǎn)量中圖分類號S643.5文獻標(biāo)識碼A文章編號0517-6611(2007)21-06513-03EffectsoftheDifferentFertilizationLevelsontheGrowthandDevelopment,andProphaseYiel
