Special feed for comprehensive planting and breeding of rice and fish in saline-alkali water area and processing technology thereof

Abstract

The invention discloses a special feed for comprehensive planting and breeding of rice and fish in saline-alkali waters and a processing technology thereof. Comprising the following raw materials in parts by weight: 0-20 parts of fish meal, 5-1 part of chicken meal, 10-15 parts of soybean meal, 0-10 parts of rapeseed meal, 0-10 parts of cottonseed meal, 3-10 parts of rice bran, 3-5 parts of rice protein, 3-5 parts of blood meal, 5-10 parts of wheat germ, 5-10 parts of fish soluble, 3-8 parts of artemia powder, 3-5 parts of kelp powder, 3-5 parts of alfalfa meal, 3-5 parts of spirulina, 0-2 parts of glucose, 2-5 parts of citric acid, 3-10 parts of oil, 0-15 parts of flour, 2-8 parts of tapioca flour, 1.2-1.6 parts of monocalcium phosphate, 0.1-0.3 part of choline chloride and 0.5-1 part of a vitamin premix. 0.6-0.8 of a trace element premix, and also comprises lactobacillus and a compound enzyme preparation. The feed is high in nutrient component absorption rate and small in mineral substance addition amount, the salt and alkali stress capacity of fishes is improved, and rice and aquatic products can meet the green organic standard in a rice-fish comprehensive planting and breeding mode.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a special feed for comprehensive planting and breeding of rice and fish in saline-alkali waters and a processing technology thereof. Background technique [0002] There are about 690 million mu of low-lying saline-alkali waters in China, and inland saline waters accounting for about 55% of the country's lake area. These saline-alkali land water resources cover 17 provinces, municipalities and autonomous regions in my country. Moreover, the water quality of these inland saline-alkali waters is mostly non-marine saline water, with complex water chemical composition, high salt, high alkali, and high pH value. Humans and animals cannot drink or irrigate farmland, and most of them are in a state of long-term neglect. "Change from rice to alkali" and "to change from fish to alkali" have been proved to be one of the effective ways to develop and utilize this part of land resources, which ...

Problems solved by technology

Feed-grade mineral additives contain a certain amount of heavy metals due to their source or production process. At the same time, rice has a strong ability to purify water. Therefore, if the water contains heavy metals, it is easy to cause rice to Exceeding the standard of medium and heavy metals will seriously affect the food safety of rice; as far as the output of rice products is concerned, if the special feed for pond culture is continued to be used to feed aquatic animals in the paddy field, when the water body conditions and breeding density undergo major changes, it is easy to cause feed damage. The loss of a large amount of nutrients into the water body, the most important nutrients are nitrogen and phosphorus

Nitrogen and phosphorus are not only the nutrient elements of aquatic organisms, but also the nutrient elements needed by crops. If the balance of nitrogen and phosphorus in the water body is not balanced, it will cause excess nitrogen and phosphorus. "green and late ripening" or even lodging, which seriously affects rice yield
