【摘要】 大豆收获籽粒兼采叶饲用是贵州较普遍的农牧结合生产方式。对13个大豆品种的粒叶兼收性试验结果:各品种采干叶量为63.2～151.5公斤/亩,采叶籽粒减产率为10～61％,粒叶换收率0.84～7.01,叶片蛋白质为17.56～24.78％。分析了采叶对籽粒产量和经济性状的影响。通过经济评价将参试种分为主收籽粒型、主收叶片型、中间型三类。提出了适宜采叶的品种及其性状指标。更多还原

【Abstract】 Harvesting both seed and leaves as forage is a common production style in soybean cultivation in Guizhou province. The experiment on 13 soybean cultivars showed ihat the grain yield reduced by 10-61% when the weight of leavesplucked was 63.2-151. 5kg/um. The exchanging rates between seed, and leaves wns 0.81-7.01. Protein contents in leaveswere 17.56-24.78%. Effect of plucking leaves on economic characters were also studied.According to the econmic evaluation of 13 cultivars tested it may be dividedinto three types: mainly harvesting seed, mainly harvesting leaves, and both seed arid leaves equally. In this study,oultvars suitable for both harvesting seed and plucking leaves were found and their characters indexes were provided.更多还原
