枝豆在中国称毛豆,在成熟前采收供食用的一类大豆的总称。目前,日本国内的多数枝豆品种的株高45～75厘米之间,生育期较短,一般在100～120天,植株分枝力较强,着荚部位低,百粒重较大,在30克左右。枝豆种子的蛋白质含量较高,幼芽拱土力比较弱,在成后易烈荚,子粒吸水速度极快,遇水后,种子的芽率明显下降,所以,枝豆种子的繁殖难度较大。根据两年来的实践,初步掌握了该类品种的特征特性,如果采取适宜的栽培技术措施,加强种子田的田间管理,种子收获后注意防水,每亩获得100公斤以上的成品种子。 Stem beans called green beans in China, before harvest mature for the general term for a class of soybeans. At present, most of the varieties of twig varieties in Japan have plant height of 45-75 cm, short growing period, generally 100-120 days, strong plant branching force, low pod parts and large 100-grain weight. At 30 About grams. The protein content of the twig bean seeds is relatively high, and the sprouting strength of the sprout buds is relatively weak. After the seedlings become easy and vigorous, the water absorption speed of the seed particles is very fast. After the water is in contact with the seeds, the germination rate of the seed drops obviously. According to the practice in the past two years, the characteristic features of this species have been initially mastered. If appropriate cultivation techniques and measures are taken to improve field management of the seed fields and pay attention to waterproofing after the seeds are harvested, more than 100 kg of finished seeds per mu will be obtained.
