- 摘要:
- 以大葱为试材，在青海大通塔尔镇塔尔湾村川水地进行连续2年的大葱不同钾肥单因素试验。结果表明：地膜大葱栽培中，施钾肥对大葱的株高影响不大，合理施钾可以提高大葱的葱白长度、单株重量、假茎粗度；钾肥用量在0~135 kg/hm2范围内，大葱葱白的维生素C含量随着钾肥用量的增加而增加；钾肥用量在135~270 kg/hm2时大葱葱白的维生素C最高；不施用钾肥的大葱葱白的硝酸盐含量最高，但与不同钾肥施用量的大葱葱白的硝酸盐含量没有显著差异，且随着钾肥施用量的增加大葱葱白的硝酸盐含量逐渐下降；施钾肥可以提高大葱产量和经济效益，在河湟谷地大葱的钾肥施用量以90~135 kg/hm2最合适。
- Abstract:
- The single factor test on scallions with different amount of potassium application for two consecutive years was made in Tar Wan Village of Tal town in Qinghai Datong.The results showed the effect of potassium fertilizer on plant height was little,reasonable potassium application could improve stalk,single plant weight and cauloid diameter degrees in plastic greenhouse cultivation.The vitamin C content of the stalk increased with the increase of potash amount.The vitamin C content was the highest when the potash amount was 135~270 kg/hm2.The nitrate content was the highest without the potash and decreased with the increased of the potash amount,but there were no significant difference with fertilized scallions.Potassium fertilizer could increase yields and economic benefits,the most appropriate potash application amount of scallions was 90~135 kg/hm2 in Hehuang valley.
