不同春大豆品种在红壤和冲积土上的适应性研究:Ⅰ.营养生长

Study on adaptability of early soybean varieties in red soil: Ⅰ. vegetative growth

通过不同春大豆品种在红壤和冲积土上生长的比较 ,发现 6个春大豆品种在红壤土中的根和地上部的生长量均显著低于冲积土的生长量 ;乌皮青仁适宜于在红壤土种植 ,婺春 1号适宜于冲积土种植 ,而浙春 2号在两种土壤均较适应 ;塑料袋栽试验可以作为筛选大豆耐铝性品种的简便方法。

Adaptability of different early soybean varieties in red soil and alluvial soil was studied by comparison of growth of 6 soybean varieties in the two soils. Results of the experiment showed that, growth amounts of roots and aerial parts for 6 soybean varieties in red soil were significantly lower than those in alluvial soil. Adaptability of Wupiqinren in red soil was better, and Wuchu 1 in alluvial soil was better.Zhechu 2 in both soils was also better. Plastic bag cultivation was a simple and convenient method for screening Al tolerant soybean varieties.
