Problems solved by technology

[0002] Most of the current fertilizers are chemical fertilizers, but the long-term use of chemical fertilizers is expensive and has long-term adverse effects on the land. Excessive fertilizers not only increase agricultural costs, waste resources, pollute the environment, but also cause soil plowing to become rich. Nutritization, causing a series of problems such as soil secondary salinization, nitrate accumulation, and soil acidification, making the growth environment of crops worse and affecting crop yield and quality

preparation example Construction

[0022] A kind of facultative anaerobic bacteria biological fertilizer, its preparation method comprises the steps:

[0023] Step 1, strain selection: select a variety of facultative anaerobic bacteria that can not only multiply rapidly under aerobic conditions, but also grow and reproduce in the anaerobic environment of paddy fields, and combine them in a certain proportion.

[0024] Step 2, activation and purification of strains;

[0025] Step 3, expanding the culture on a liquid shaker;

[0026] Step 4, preparation of solid bacterial powder;

[0027] Step five, preparation of facultative anaerobic biological fertilizer.

[0028] Further, the facultative anaerobic bacteria bio-fertilizer is applied in paddy fields.

[0029] Further, the strains are specifically: denitrifying bacteria: Lactobacillus plantarum: Rhodopseudomonas palustris: Bacillus coagulans: Bacillus licheniformis: Bacillus cereus: Paenibacillus polymyxa, each strain is in parts by quantity The number ratio...

[0126] 2. Test time and place

[0127] The experiment was arranged in the paddy field contracted by Wang Guqing, a farmer of Zhongfayu Village Committee, Fayu Community, Yangyue Street, Shizong County, Qujing City. Seedlings were raised on April 4, 2018, seedlings emerged on April 12, transplanted on June 4, and harvested at one time on October 28, 2018. The rice seedling period was 61 days, the field growth time was 147 days, and the full growth period was 208 days.

Abstract

The invention relates to a facultative anaerobic bacteria biological fertilizer. The preparation method is characterized by including the steps of: 1, strain selection: selecting a variety of facultative anaerobic bacteria which can be rapidly propagated under an aerobic condition and also can grow and propagate in a paddy field anaerobic environment, and combining the facultative anaerobic bacteria according to certain proportion; 2, activation and purification of the strains; 3, liquid shaking table enlarged culture; 4, preparation of solid bacterial powder; and 5, preparation of the facultative anaerobic biological fertilizer.

Description

technical field [0001] The invention relates to the field of biological fertilizers, in particular to facultative anaerobic bacteria biological fertilizers. Background technique [0002] Most of the current fertilizers are chemical fertilizers, but the long-term use of chemical fertilizers is expensive and has long-term adverse effects on the land. Excessive fertilizers not only increase agricultural costs, waste resources, pollute the environment, but also cause soil plowing to become rich. Nutritization causes a series of problems such as soil secondary salinization, nitrate accumulation, and soil acidification, which makes the growth environment of crops worse and affects the yield and quality of crops. In recent years, my country has closely focused on the main line of agricultural supply-side structural reform, focusing on grain production functional areas, important agricultural product production protection areas and characteristic agricultural product advantage areas...
