不同大豆品种在养分吸收及产量上的比较

Comparison of nutrient uptake and yield of different varieties of soybean

采用盆栽试验方法对红丰11等四个大豆品种吸收利用氮、磷、钾养分的能力进行了比较研究。结果表明,在施肥一致的条件下,不同大豆品种对养分的吸收利用能力不同,养分利用率也不同,导致产量的差异。以红丰11养分吸收量最多,表现产量最高。

The pot experiment was conducted to study the effect of four varieties of soybean uptake N, P and K fertilizers. The results showed that efficiency of N,P and K uptaken and utilized was different in varieties of soybean,and also yield was different.Hongfeng11 was the most effective and the highest grain yield.
