Example Embodiment

[0048] Example 1

[0049] Prepare biological compound fertilizer as follows:

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

[0051] 2. Cultivate Chlorella pyrenoidosa: (1) Pick a small ring of Chlorella pyrenoidosa algal species, streak on the steril...

Example Embodiment

[0053] Example 2

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

Example Embodiment

[0055] Example 3

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

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 ...
