Embodiment 1

[0027] A kind of microbial organic fertilizer of the present invention is formulated by the component of following mass fraction:

[0028]

[0029] The microbial organic fertilizer of this embodiment is in the form of water-containing powder, has no foul smell, has a water content of ≤30%, and a viable count of ≥0.2 billion / g, wherein the viable count of Phanerochaete chrysosporium is ≥0.01 billion / g, and Bacillus thuringiensis The number of viable bacilli is ≥0.01 billion / g, and the mass ratio of nitrogen, phosphorus and potassium in the rapeseed cake fertilizer is 3.5:1:1.

[0030] The preparation method of above-mentioned microorganism organic fertilizer, comprises the following steps:

[0031] 1. Preparation and cultivation of Phanerochaete chrysosporium bacteria liquid

[0032] (1) Strain activation: insert the parent species of Phanerochaete chrysosporium into the potato plate activation medium for activation;

[0033] (2) Dissolve the Phanerochaete chrysosporium sp...

Embodiment 3

[0048] Embodiment 3: the application of microbial organic fertilizer in the growth of tobacco field

[0049] The microbial organic fertilizer (T 1 ), the microbial organic fertilizer (T 2 ) is used as basal fertilizer or hole fertilizer, applied to tobacco field production, covered immediately after being applied, the dosage per mu is 20Kg, microbial organic fertilizer does not contact chemical fertilizer, does not mix with chemical fertilizer; Under the condition that keeps other conditions all identical, A comparative experiment was carried out in the treated tobacco field with only the application of decomposed rapeseed cake fertilizer as the control sample (CK). The plant samples and soil samples of different growth stages of tobacco were collected respectively, including the group tree stage (30d after transplanting), the flourishing stage (50d), the topping stage (57d), the lower leaf mature stage (69d), and the middle leaf mature stage (93d). ), upper leaf maturity st...

Abstract

The invention discloses a microbial organic fertilizer which is prepared from the following raw materials by weight percent: 50-60% of decomposed rapeseed cake fertilizer, 25-35% of bentonite, 10-14% of phanerochaete chrysosporium solution and 0.5-1% of wettable powder of bacillus thuringiensis. The microbial organic fertilizer disclosed by the invention can be used as the base fertilizer or hole fertilizer to be applied during crop production and is covered immediately after being applied. 15-30kg of the microbial organic fertilizer is applied to the filed per mu. When the microbial organic fertilizer is applied, the chemical fertilizer can not be applied together. The microbial organic fertilizer has multiple functions and good application effect.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a microbial organic fertilizer and its application. Background technique [0002] Soil is a vital part of the human food chain and the basis of agricultural production systems. It is not only an important medium for crop growth but also maintains crop productivity, affecting the quality of the environment and the health of plants (even humans). However, for a long time, the extensive use of chemical fertilizers and pesticides has seriously damaged the soil structure, causing problems such as soil compaction, reduced productivity, high content of heavy metals and organic toxics, degradation of beneficial bacteria, and imbalance of the soil ecological environment, which has also caused crop quality to decline. , serious pests and diseases, bad taste, and serious threats to human health through the food chain. Therefore, the current agricultural production urgently needs to reduce the us...
