摘要
以从海水中提取的亚硫酸钾(简称海水亚硫酸钾)作为蒸煮剂,蒸煮麦草和稻草,分析了其蒸煮废液的肥料成分,并进行了麦草、稻草亚硫酸钾蒸煮废液肥料在黄瓜上应用效果的田间试验。结果表明,麦草和稻草亚硫酸钾蒸煮废液对促进黄瓜生长、提高产量、改善品质、改良土壤都有明显效果,为今后推广麦草、稻草亚硫酸钾蒸煮废液作肥料施用在蔬菜上提供了科学依据。
Wheat straw and rice straw were cooked with potassium sulfite extracted from seawater. Fertilizer values of the potassium sulfite pulping spent liquors were estimated. The fertilizer application field trials of these two spent liquors in cucumber were carried out. The results showed that the potassium sulfite pulping spent liquors of wheat straw and rice straw could promote the growth of cucumber, increase production, improve cucumber quality and improve the soil.
