1 本田选择土壤pH值6.8～7.5,有机质含量3.5%～4.5%,耕层厚度25～30cm,田间持水量在30%以上。2 密度栽培技术研究采用“方选92-01”大豆新品系。该品系属有限结荚习性,分枝能力强,根据土壤肥力的不同和管理水平的不同,确定为: 一般肥力地块:70cm×13.2cm,每穴1～2株,保苗15万株/hm~2左右。中等肥力地块:70cm×19.8cm,每穴2株,保苗15～16万株/hm~2左右。
Honda selected soil pH value of 6.8 to 7.5, organic matter content of 3.5% to 4.5%, topsoil thickness of 25 ~ 30cm, field capacity of more than 30%. 2 density cultivation technology research using “square selection 92-01 ” new soybean lines. The strain is a limited pod habit with strong branching ability. According to the difference of soil fertility and management level, it is determined as follows: general fertility plots: 70cm × 13.2cm, 1 ~ 2 per hole, seedling 150,000 / hm ~ 2 or so. Medium fertility plots: 70cm × 19.8cm, 2 per hole, seedling 15 ~ 160,000 / hm ~ 2 or so.
