大豆高产理想株型的研究,国内引起各方面的注意,并已进行深入的研究。盖均益教授通过群体生理研究指出,高产类型的叶面积指数、光合速率、干物重、荚干重、粒干重在动态过程中比中、低产类型均较大,成熟时表现生物产量及收获指数均较高。其营养生长期相对较短而生殖生长期相对较长,两者的重叠期也相对较短,其产量在空间的分布垂直方向为均匀型,水平方向为主茎型或主茎分枝并重型。董钻教授通过研究指出,大豆生产是群体生产,大豆产量是群体产量,创造325公斤/亩的产量,必须建立相应的群体结构,应当育成适宜的株型材料。王喜良提出,亩产447——583斤的产量结构应是平方米株数38±14株,株粒数56±26,平方米粒数2000±400,百粒重20±3克。许冬梅先生提出,单位面积总荚数与产量关系最为密切(r=0.934),可做为设计特定生态条件下高产模式的
Soybean high yield ideal plant type research, the domestic attracted all attention, and has carried out in-depth research. According to the research results of population physiology, Professor Gai Junyi pointed out that the leaf area index, photosynthetic rate, dry matter weight, dry weight of pod and dry weight of kernel in the high-yielding types were all higher than those in middle and low yield in dynamic process, Index is higher. The vegetative growth period is relatively short and reproductive growth period is relatively long, the overlap period of the two is relatively short, the yield distribution in the vertical direction of the space is uniform, the horizontal direction of the main stem or main stem branch and heavy . Professor Dong drilling pointed out through research that soybean production is a group production. Soybean yield is a group output, and a yield of 325 kg / mu is created. Corresponding community structure must be established and proper plant type materials should be bred. Wang Xiliang proposed that the yield structure of 447-583 kg per mu should be 38 ± 14 strains per square meter with 56 ± 26 grains per plant, 2000 ± 400 grains per square meter and 20 ± 3 grains per 100 grains. Mr. Xu Dongmei suggested that the relationship between the total pods per unit area and the yield was the highest (r = 0.934), which could be used as a model for designing high-yielding crops under specific ecological conditions
