Chinese medicinal residue biological organic fertilizer and preparation method thereof

Abstract

The invention relates to a fertilizer, in particular to a Chinese medicinal residue biological organic fertilizer. The Chinese medicinal residue biological organic fertilizer is prepared from the following raw materials in parts by weight: 50 to 75 parts of Chinese medicinal residues, 15 to 35 parts of bran, 10 to 20 parts of charcoal and 0.05 to 1 part of enzyme microorganism. The living bacteria count in the biological organic fertilizer is more than or equal to 0.2 hundred million / gram, the weight percentage of organic matters is more than or equal to 45 percent, the weight ratio of total oxygen of nitrogen phosphorus and potassium is more than or equal to 5 percent, medium trace elements comprise calcium, magnesium, silicon, sulfur, iron, manganese, copper, zinc, boron, molybdenum and the like, and nutrient elements are abundant. A preparation method is simple in operation; experiments show that by applying the Chinese medicinal residue biological organic fertilizer on the basis of conventional fertilization usage, the yield of tomatoes can be improved, diseases and insect pests are reduced, the foundation is laid for high yield of the tomatoes, and the yield increasing rate is 6.98 percent; the fertilizer disclosed by the invention is applied on the basis of the conventional fertilization usage, the yield of cucumbers can be improved to different degrees, the yield increasing rate is 7.81 percent, and the foundation is laid for high yield of the cucumbers.

Description

[0001] technical field [0002] The invention relates to a fertilizer, namely a bio-organic fertilizer of traditional Chinese medicine dregs and a preparation method thereof. Background technique [0003] In the prior art, organic fertilizers refer to natural fertilizers based on organic matter, mostly human and animal feces and animal residues, and are generally divided into three categories: farmyard manure, green manure, and humic acid fertilizer. Farmyard manure is processed by farmers from human and animal manure and other raw materials. The common ones include manure, compost, biogas fertilizer, smoked soil and plant ash. Green manure is the use of all or part of its plant body as fertilizer. Common green manure crops include milk vetch, alfalfa, peas, vetch and amorpha. Humic acid fertilizers are processed from raw materials such as peat, lignite, and weathered coal. Nowadays, farmyard manure usually contains a lot of salt, which can easily lead to soil compaction. ...
