preparation example Construction
[0022] A method for preparing special compound microbial fish fertilizer for yellow catfish, which is characterized in that it comprises the following steps:
[0023] (1) Dry the aquatic plants to make the water content below 40%, cut them to 2-4cm, then add fish bone meal, vinegar lees powder, rice bran, brown sugar, salt according to the stated proportions, stir well, and mix well;
[0024] (2) Ferment the above mixture. The fermentation is aerobic composting. The fermentation water accounts for 20-30% of the total weight of the materials. The oxygen supply time is 50-60 hours in winter and 20-25 hours in summer. Fermentation temperature 45-60℃, fermentation time is 7-10 days;
[0025] (3) Mix the waste liquid sediment, pig manure, and pork slaughterhouse waste according to the stated proportions evenly, add yeast and streptococcus faecalis for fermentation; put the above substances into the pool to mix the rot, and cover the upper part with plastic The film is pre-fermented for 3...
Embodiment 2
[0031] The preparation method is the same as in Example 1.
[0032] In the juvenile stage of growth, they were fished out and fed into five tanks, each with 500 tanks. The microbial fish fertilizer and common fish fertilizer of Example 1 of the present invention were put into the four tanks at a rate of 200 kg per mu. (Control 1, produced from Beijing Century Arms Biotechnology Co., Ltd. ), the other pond does not put fish fertilizer (control 2), but put the same amount of ordinary fish food, the rest of the feed is the same, the culture environment is the same, after 2-4 months of cultivation, compare its output and the growth of the fish , As shown in Table 1 and Table 2:
[0033]
[0034]
[0035] Through the comparison of Table 1 and Table 2, it can be found that adding the compound microbial fertilizer of the present invention can promote the rapid growth of sea cucumbers, increase the EPA content, reduce fish diseases, and reduce sick and dead fish. At the same time, it...
