硼镁肥对棉花的增产效应研究

Study on Yield Increasing Effect of B and Mg Fertilizer on Cotton

为明确硼镁肥对棉花的增产效应,设4个处理（CK,习惯施肥,施硼镁肥150、300 kg/hm^2）进行对比试验。结果表明：施用硼镁肥比CK和习惯施肥处理棉花成铃数和产量有明显提高,比CK增产11.1%-16.9%。施硼镁肥300 kg/hm^2处理的产量明显优于施硼镁肥150 kg/hm^2的处理。

Four treatments were designed to determine the increasing effect of B and Mg fertilizer on cotton. The result showed that the number of bolls and yield of applying B and Mg fertilizer treatment significantly increased to CK and normal applying fertilizer treatment. The yield increased 11.1%-16.9% comparing to CK. The yield of applying B and Mg fertilizer treatment （300 kg/hm^2 ） was higher than that of treatment （ 150 kg/hm^2 ） .
