(I) Micro-storage of micro-storage fish by micro-composite fermentation of straw is a process in which the straw is fermented by micro-composite bacteria and put into the fish pond. It can be used as base fertilizer, top dressing, and fish bait. It is a development food-saving type. An effective approach to fisheries. 1. Preparation of Straw Microbial Bacteria: 5 g of straw micro-complex bacteria can handle wheat straw, straw, corn stalk 1000 kg or green feed 2000 kg. Before processing the straw, first pour the micro-organism bacteria into 500 ml of glucose solution with a concentration of 1%, and then place it at a temperature of about 25°C for 1 to 2 hours so that the strains can be compounded and then poured into 1000 to 1500 kg of cleanliness. 0.8% to 1% salt water is uniform. 2, straw specifications and into the kiln method: straw crushed to 3 to 5 cm long. When entering the kiln, first lay straw 20 to 30 centimeters thick, and then evenly spray the bacteria liquid water, compact and then lay 20 to 30 centimeters thick straw, and then spray the bacteria hydraulically; until 30 to 40 cm higher than the cellar mouth Seal it again. If it is not full the same day, it can be covered with plastic film and filled the next day. In the micro-storage of wheat straw or rice straw, a layer of barley flour or bran, rice bran and other concentrates can be laid, with an amount of 5 to provide a certain amount of nutrients for the initial breeding of bacteria, improve the quality of micro-storage. 3, cellaring method: After full compaction, evenly sprinkle salt in the uppermost layer, the amount of 250 grams per square meter, covered with a plastic film seal, to ensure that the micro-reservoir exhibits anaerobic state. During the process of micro-storage of straw, leakage of water leakage is strictly prevented. 20-30 days after cell sealing, the fermentation process can be completed. Straw micro-feeds mainly feed on herbivorous fish. (b) Through the application of photosynthetic bacteria, crop stalks such as wheat stalks and corn stalks can be made into high-efficiency fish biofeeds. The feed has good comprehensive nutrition, and due to its large volume and small specific gravity, it can be suspended in water for about 1 hour, which is good for fish feeding, digestion and absorption. It is an ideal feed for fish and shrimp. In addition, the method of processing the feed is simple, and rich straw resources can be utilized. The production methods, nutrient components, and use effects of the feed are as follows. 1, production methods: 1 using a grinder to smash the crop straw. 2 Put the straw powder into the fermentation tank, add straw powder weight 80% water, 1% glucoamylase, 1% compound enzyme, 1% sodium chloride, 0.5% live yeast, 0.5% lactic acid bacteria . 3 access to 3% photosynthetic bacteria, cultured at 15 ~ 35 °C temperature for 2 days. When the layer is covered with white hyphae and emits aroma, a high-efficiency fish biofeed is obtained. 2. Nutrients: The test results showed that: 12.31% of crude protein, 4.2% of crude fat, and 19.34% of crude fiber, of which 3 main amino acids were: lysine 0.68%, methionine 0.16%, and cystine 0.19%. 3. Use effect: Feeding fish and shrimp with high-efficiency fish bio-feed has the advantages of high survival rate, less disease, less water change, high yield, and low cost.
