摘要
采用盆栽方法 ,对黑龙江省和吉林省的 3份抗旱性大豆品种和 5份喜肥水性大豆品种的根系性状进行了比较研究。结果表明 :不同特性大豆品种的根系性状存在差异 ,与喜肥水性大豆品种相比 ,抗旱性大豆品种根系比较发达 ,具有相对较大的根系重量、较大的根体积、较强的根系吸收活性及较发达的主根和下部侧根。
A comparative study between 3 drought resistant and 5 water-fertilizer soybean varieties was done to find out whether there are differences on root system between the two types of soybean varieties. The results showed that there were differences in the root characteristics between soybean varieties of different types. The drought resistant soybean varieties had a relatively well-developed root system compared with the water-fertilizer favorite ones. The former had more root weight, larger root volume, stronger root absorbing capacity, longer length of taproot and lower lateral roots.
