阅读说明：本技术 一种利用微生物得到适用于绿叶蔬菜的液肥及制备方法 (Liquid fertilizer obtained by using microorganisms and suitable for green leaf vegetables and preparation method thereof ) 是由 郑殿峰 郑殿德 冯乃杰 于 2021-09-30 设计创作，主要内容包括：本发明公开了一种利用微生物得到适用于绿叶蔬菜的液肥及制备方法,包括微生物发酵菌液1-5份、有机肥10-35份、营养元素2-5份、叶绿素2-5份、钾盐5-10份和水10-20份,微生物发酵菌液为白及内生木霉菌和杜仲内生菌分别经培养基发酵后得到的发酵菌液。其制备过程为将微生物加入一定比例的碳源和氮源后进行发酵,得到的微生物发酵菌液再添加进有机肥中进行二次发酵后,进行固液分离,将二次发酵液加入处方量的营养元素、叶绿素、磷酸二氢钾搅拌使其溶解,即得。能够解决绿叶蔬菜农药残留易超标问题及化肥长期过量使用导致的食品安全和环境问题,在保证肥料能够提供充足和各种养分的同时,增加具有防治病虫害功能的天然有效成分,既方便农户操作,降低人工成本,又减少了化肥和农药的使用,达到提高绿叶蔬菜食用的安全性和有效利用富营养发酵液的目的,做到了绿色环保。(The invention discloses a liquid fertilizer suitable for green leaf vegetables and a preparation method thereof, wherein the liquid fertilizer is obtained by utilizing microorganisms, and comprises 1-5 parts of microbial zymogen liquid, 10-35 parts of organic fertilizer, 2-5 parts of nutrient elements, 2-5 parts of chlorophyll, 5-10 parts of potassium salt and 10-20 parts of water, wherein the microbial zymogen liquid is zymogen liquid obtained by fermenting bletilla striata endophytic trichoderma and eucommia ulmoides endophytic fungi respectively through culture media. The preparation process comprises the steps of adding a carbon source and a nitrogen source into microorganisms in a certain proportion, then fermenting, adding the obtained microorganism zymocyte liquid into an organic fertilizer, carrying out secondary fermentation, carrying out solid-liquid separation, adding nutrient elements, chlorophyll and potassium dihydrogen phosphate in the amount according to the prescription, and stirring to dissolve the nutrient elements, chlorophyll and potassium dihydrogen phosphate. The problem that pesticide residues of green-leaf vegetables are prone to exceeding standards and the problem that the chemical fertilizer is prone to being used excessively for a long time and causing food safety and environment problems can be solved, the natural effective ingredients with the function of preventing and treating plant diseases and insect pests are added while the fertilizer is guaranteed to be capable of providing sufficient and various nutrients, operation of farmers is facilitated, labor cost is reduced, the use of the chemical fertilizer and the pesticide is reduced, the purposes of improving edible safety of the green-leaf vegetables and effectively utilizing rich nutrient fermentation liquor are achieved, and green and environment-friendly effects are achieved.)
