Compound microorganism bacterial fertilizer special for helianthus tuberosus and preparation method thereof

Abstract

The invention belongs to the field of fertilizer, and particularly relates to compound microorganism bacterial fertilizer special for helianthus tuberosus. The compound microorganism bacterial fertilizer special for the helianthus tuberosus is characterized by comprising, by weight, 50-100 parts of leaf mold, 20-90 parts of plant ash, 10-20 parts of urea, 5-10 parts of ammonium bicarbonate, 1-6 parts of potassium sulphate, 5-15 parts of manure, 0.03-0.2 part of compound microorganism bacterial agent, 1-10 parts of calcium superphosphate and 0.001-0.03 part of microelement. The compound microorganism bacterial fertilizer special for the helianthus tuberosus, which is prepared through the method, has the following advantages that the fertility of soil is enhanced, the soil is activated, the organic content of the soil is increased, the land productivity is enhanced, the soil is made to be of a good granular structure through a large number of beneficial organism flora, the moisture and ventilation conditions of the soil are improved, the water retaining capacity of the soil is enhanced, phosphorus and potassium which are hardened in the soil can be dissolved and activated, and meanwhile nitrogen in the air is converted into nitrogen fertilizer to be absorbed by plants.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a special compound microbial fertilizer for Jerusalem artichoke, and also relates to a preparation method of the compound microbial fertilizer. Background technique [0002] Jerusalem artichoke, also known as chrysanthemum ginger, Jerusalem artichoke, devil ginger, is an edible root vegetable. Native to North America, it was introduced to Europe in the 17th century and then to China. It blooms in autumn and has small yellow disc flowers shaped like chrysanthemums. It is generally propagated by tubers in production. Its underground tubers are rich in fructose polymers such as starch and inulin. They can be eaten, cooked or porridge, pickled vegetables, Sun-dried Jerusalem artichoke, or make starch and alcohol raw materials. [0003] Jerusalem artichoke is the tuber or stem leaf of Jerusalem artichoke, the upper part of the stem is branched, covered with short rough hairs...
