通过３年田间观测，比较研究了３种结荚习性不同的大豆品种（有限性铁丰２４号、亚有限性辽豆１０号、无限性沈豆Ｈ－５０６４）开花、结荚、鼓粒进程。铁丰２４号出苗后第６９．５天始花，花期１８．５天，植株中部先开花，渐次向上向下开放；辽豆１０号出苗后第５２．５天始花，花期３４天，植株下部先开花，渐次向上开放；沈豆Ｈ－５０６４出苗后第５４．０天始花，花期４０．５天，开花次序与辽豆１０号相同。铁丰２４号全株结荚率为３３．５３％、主花序、副花序、分枝的结荚率分别为３６．８４％、４８．９４％、２０．２９％，主要结荚部位在植株的中上部；相应地，辽豆１０号为３５．７１％、５５．８１％、２５．００％和０，中部结荚居多；沈豆Ｈ５０６４为２４．００％、３５．９２％、１２．１２％和６．６７％，豆荚分布均匀。铁丰２４号、辽豆１０号、沈豆Ｈ－５０６４分别在开花后第１０－１９天、１２－２２天、１５－２６天豆荚伸长较快，基本接近品种的固有长度和宽度；豆荚厚度增长因品种籽粒灌浆进程而异。３个品种自幼荚出现至豆荚长成所需时间基本相同（约６３天）。３个品种单粒的增重过程符合Ｌｏｇｉｓｔｉｃ方程，前期增重缓慢，中期加快，后期又减慢，分别在开花后第４９．?
Through three years of field observation, the effects of three kinds of soybean cultivars with different pod habitats (limited Tiefeng 24, sub-limited Liaozu 10 and infinite Shen-beng H-5064) were compared in flowering, podding and drumming process . Tiefeng 24 began to flower on the 69.5th after the emergence, with the flowering period of 18.5 days. The middle part of the plant began to bloom first, then gradually opened upwards and downwards. The first flowering and the second flowering stage were on the 52.5th day after the emergence of Liaodou 10, The lower part of the first flowering, and gradually opening up; Shen-bean H-5064 54.0 days after emergence of the first flowering, flowering 40.5 days, flowering order and Liaodou 10 the same. The rate of podding in Tiefeng 24 was 33.53%, and the rate of podding in main inflorescences, accessory inflorescences and branches was 36.84%, 48.94% and 20.29% respectively. The main pod sites were in plant Of the middle and upper part; Correspondingly, Liao Dou No.10 was 35.71%, 55.81%, 25.00% and 0, the middle part was mostly pod; the H5064 was 24.00% and 35.92%, respectively. 12% and 6.67%, pod distribution evenly. Tiefeng 24, Liaodou 10 and Shennong H-5064 were faster than the natural length and width of the cultivars on the 10th-19th, the 12th-22th and the 15th-26th days after flowering, respectively. The pods The thickness increase varies with the grain filling process of the variety. The time required for the three cultivars to emerge from pods to grow into pods was about the same (about 63 days). The weight gain of single grain of three cultivars accorded with Logistic equation, the weight gain was slow in the early period, the mid-term accelerated and the later was slowed down, respectively. ?
