钾对大豆产量及品质的影响

Effect of potassium on the yield and quality of soybean

采用田间试验方法,研究了钾对大豆产量、产量构成因素及品质的影响。结果表明,钾对大豆产量构成因素有增强作用,钾能显著提高大豆产量,改善大豆品质。产量随着施K量的增加而增加,当施纯K量150kg/hm2时,高油品种东农434产量达2727kg/hm2,高蛋白品种黑农35产量达2651kg/hm2。施钾有提高大豆脂肪含量、降低蛋白质含量的趋势。表4,参6。

The effect of potassium on the yield and quality was studied in the field.The result showed that potassium had a positive effect on the factors of yield,a good effect on the yield and quality of soybean.With potassium application,the yield of soybean increased.An yield of dongnong343 increased to 2 727kg/hm^2 and that of heinong35 increased to 2 651kg/hm^2 when the amount of the potassium applied in field was 150kg/hm^2.The application of potassium fertilizer had a positive effect on oil content and a negative effect on protein content of soybean.
