A liquid bacterial fertilizer for fermenting garlic straw by Enterobacter ludwig and its preparation method

Abstract

The invention relates to a liquid bacterial fertilizer obtained by fermenting garlic straws by using enterobacter ludwigii and a preparation method thereof. The liquid bacterial fertilizer is preparedfrom garlic straw, potassium dihydrogen phosphate, soybean meal, corn flour, glucose, yeast powder, water and enterobacter ludwigii (LB) fermentation liquid, wherein the enterobacter ludwigii is Enterobacter ludwigii B424; the preservation number of the enterobacter ludwigii is CGMCC No.14915; the preservation institution of the enterobacter ludwigii is China General Microbiological Culture Collection Center; the preservation address is No. 3, No. 1 Courtyard, West Beichen Road, Chaoyang District, Beijing, China; the preservation date is November 16, 2017. Through the produced disease-resistant multifunctional liquid bacterial fertilizer capable of accelerating growth of crops, the application of chemical fertilizers and pesticides in farmlands is reduced; the farmland ecological environment is improved; the liquid bacterial fertilizer has great economic, social and ecological benefits.

Description

technical field

[0001] The invention relates to the technical field of straw organic fertilizer production, in particular to a liquid bacterial fertilizer for fermenting garlic straw by Enterobacter ludwig and a preparation method thereof. Background technique

[0002] China is the main production area and the largest exporter of garlic in the world, with an annual output of more than 11 million tons of garlic, accounting for more than 66% of the world's total production. Shandong is the main production area of ​​garlic in my country. The world produces more than 3.7 million tons of garlic straw every year. If it is not handled in time, it will cause serious environmental pollution and other ecological problems. Garlic stalks are rich in nutrients, and non-recycling causes serious waste of resources.

[0003] At present, researchers have returned garlic straw to the field. For example, the publication number CN103238445A provides a method for planting selenium-enriched garl...
