Embodiment 1

[0049] Prepare biological compound fertilizer as follows:

[0050] 1. Cultivation of nitrogen-fixing Anabaena: (1) Pick a small circle of nitrogen-fixing Anabaena species, inoculate it on a BG-11 solid medium plate, streak and separate it, and cultivate it under the conditions of 28°C and 3000 lux light. (2) Pick a single algae colony from the activated BG-11 plate, inoculate it into 100 mL of BG-11 liquid medium, and culture continuously for 5 days on a constant temperature shaker at 28°C, 3000 lux light, and 140 r / m. (3) Inoculate nitrogen-fixing Anabaena into 50L BG-11 liquid medium at an inoculum size of 7% (v / v), under the conditions of 28°C, 300lux light, 12h:12h light-dark ratio and 140r / m Cultivate nitrogen-fixing Anabaena for 7-8 days until its concentration reaches 10 6 ~10 7 individual / mL.

[0051] 2. Cultivate Chlorella pyrenoidosa: (1) Pick a small circle of Chlorella pyrenoidosa species, draw a line on the sterilized Basal solid medium plate containing 10g / L g...

Embodiment 2

[0054] The biological compound fertilizer was prepared with reference to the method described in Example 1, the only difference being that nitrogen-fixing Anabaena and Chlorella pyrenoidosa were mixed in the following parts by weight: 40 parts of nitrogen-fixing Anabaena pyrenoidosa and 7 parts of Chlorella pyrenoidosa.

Embodiment 3

[0056] The biological compound fertilizer was prepared with reference to the method described in Example 1, the only difference being that nitrogen-fixing Anabaena and Chlorella pyrenoidosa were mixed in the following parts by weight: 45 parts of nitrogen-fixing Anabaena pyrenoidosa and 10 parts of Chlorella pyrenoidosa.

Abstract

The invention provides a bio-compound fertilizer, which is prepared from blue algae and green algae as raw materials. The bio-compound fertilizer has the advantages of good fertilizer effect, short production period and low cost. The invention also provides a compound fertilizer prepared from blue algae, green algae, azotobacter chroococcum and trichoderma as raw materials. The compound fertilizer has the advantages of yield improvement, pathogenic bacterium resistance and saline-alkali soil improvement. The invention also provides a the preparation method of the bio-compound fertilizer provided by the invention. The preparation method has the characteristics that the production period is short; the cost is low; the scaled production can be realized.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a biological compound fertilizer and a preparation method thereof. Background technique [0002] With the rapid increase of the population, in order to meet the food demand, the amount of chemical fertilizers in my country is showing a continuous growth trend. The application of chemical fertilizers has made a great contribution to solving the problem of food shortages. Disruption of ecological balance. Studies have shown that excessive application of nitrogen fertilizers continues to accumulate in the soil. After reaching a certain level, it will cause the deterioration of soil environmental quality, cause soil compaction, hardening, and decline in fertility. At the same time, it will cause harm to organisms, water bodies, air, and human health. With the development of green agriculture, my country pays more and more attention to the application of biological fertilizer or biological ...
