肇庆地区春大豆品种适应性筛选与分析

Screening and Analysis of the Adaptability of Spring-sowing Soybean in Zhaoqing Area

[目的]筛选适合肇庆地区种植的春大豆品种。[方法]以大豆品种华春2号(CK)、华春6号、华春8号、泉豆5号为试验材料,对不同大豆品种的产量、生育期、农艺性状、蛋白质和脂肪含量进行比较。[结果]4个大豆品种都能正常成熟,平均产量在2 700.00 kg/hm^2以上,均适合在肇庆市各县春播种植。其中华春8号产量最高,平均产量为3 643.50 kg/hm^2,蛋白质含量45.1%,脂肪含量20.0%,百粒重24.2 g,平均生育期96 d。[结论]华春8号可在肇庆地区进行大面积示范推广。

[Objective] To screen the spring soybean variety suitable to be planted in Zhaoqing Area. [Method]With soybean varieties Huachun2,Huachun 6,Huachun 8 and Quandou 5 as the test material,we compared the yield,growth period,agronomic characters,protein and fact contents of different varieties. [Result] The four different soybean varieties showed normal maturity,their yields were all more than 2 700.00 kg/hm2,which were suitable to be planted in different counties of Zhaoqing City. Among them,Huachun 8 had the highest yield of 3 643.50 kg/hm2,with 45.1% protein content,20.0% fat content,24.2 g 100-grain weight and 96 d growth period.[Conclusion]Huachun 8 could be widely demonstrated and promoted in Zhaoqing Area.
