摘要
近年来化肥过量问题严重,导致土壤盐渍化严重。本文通过有机肥替代化肥,研究不同有机肥处理对土壤和小青菜的影响。结果表明,蚯蚓粪与黄腐酸肥料组合均能提高作物的抗病性,提高存活率。其中生命源黄腐酸肥料对土壤有良好的酸碱缓冲性质,同时可以有效地降低小青菜中的亚硝酸盐含量;蚯蚓粪相对于其他肥料肥力较高一点,同时可以降低小青菜的根粗,从而提升小青菜的外观品质,降低亚硝酸盐含量,提升食用品质。
In recent years,the problem of excessive fertilizer has caused serious soil salinization. In this paper,the effects of different organic fertilizers on soil and pakchoi have been studied by using organic fertilizer instead of chemical fertilizer.The results showed that vermicompost and fulvic acid fertilizer combination could improve crop resistance and the survival rate. The life source of fulvic acid fertilizer had good properties of soil pH buffer, and nitrite content in pakchoi decreased; compared to other fertilizer,vermicompost fertilizer and high fertility point, and it could reduce from certain root diameter so as to improve the appearance quality of pakchoi, reduce the nitrite content ,improve edible quality.
