- 摘要:
- 对合丰43和绥农10这两个熟期接近、不同结荚习性的品种在正方形栽培条件下大豆单株营养面积和群体产量、产量构成因素、单株和根系生长发育的关系进行了探讨。结果表明,这两个品种的最高产量单株营养面积均为442.60 cm2[(21.03 cm×21.03 cm)、22.59株/m2],合丰43和绥农10的有效单株营养面积分别为850 cm2[(29.15 cm×29.15 cm)、11.76株/m2]、733.87 cm2[(27.82 cm×27.82 cm)、13.63株/m2],叶面积指数、单株干物重、总根长、根总表面积、根体积均随单株营养面积的增加而增加。单株营养面积和单株荚数、单株粒数、单株粒重呈显著正相关性。
- Abstract:
- The relation between soybean nutrient area per plant and yield, its yield components, development of plant and root under square planting on Hefeng 43 and Suinong 10 with close growing period but different pod habit was discussed.The nutrient area per plant with the maximum yield on both of Hefeng 43 and Suinong 10 was 442.60 cm2[(21.03 cm×21.03 cm),22.59 plant/m2]and effective nutrient area per plant were 850cm2[(29.15 cm×29.15 cm), 11.76 plant/m2] and 733.85cm2[(27.82 cm×27.82 cm), 13.63 plant/m2].Leaf area index, dry weight per plant, length of roots, surface area of roots, and volume of roots went up with increasing of nutrient area per plant. The linear correlation coefficients between nutrient area per plant and pod number per plant, grain number per plant, grain weight per plant were significant.
