Embodiment Construction

[0046] The nutrition of the present invention is to add rare earth additives, nitrogen, phosphorus and potassium fertilizers after organic matter is fermented, high-temperature sterilized and crushed, and then stirred and crushed to obtain the product.

[0047] The formula of nutritional material of the present invention is as follows:

[0048]

[0049] The formula of the rare earth additive is as follows:

[0050]

[0051] Effect of the present invention on fish growth

[0052] Studies by Shi Wenlei and others have shown that two comparison experiments with different doses (concentrations) were carried out in the aquarium indoors. As a result, the effect of adding 45 mg / kg rare earth additives to the feed was the best, and the fish weight gain rate of the test group was higher than that of the control group. 45.3%, and the fish body weight gain rate of other each group also all improves to some extent than control group (seeing attached table 1). Compared feed efficie...

Abstract

The present invention relates to the application of RE additive as nutrient material in cultivating water. The nutrient material for cultivating water consists of: RE additive 0.02-0.10 weight portions, organic matter 5-10 weight portions, nitrogen fertilizer 16-20 weight portions, phosphate fertilizer 4-7 weight portions, potash fertilizer 2-4 weight portions, and medium content micro element compounds 3-5 weight portions. The RE additive consists of La2O3 65-90 weight portions, Pr6O11 1.9-3.5 weight portions, CeO2 6-15 weight portions, Nd2O3 3.4-4.0 weight portions and other RE oxides 0.5-1.5 weight portions. The medium content micro elements include at least one of Mo, Fe, B, Zn, Mg, Si and Ca.

Description

Technical field: [0001] The present invention relates to the nutrient material for aquaculture water body and its preparation method. Background technique: [0002] For a long time, the aquaculture industry in my country and the world, such as fish farming, shrimp farming, and crab farming, in order to meet the needs of nutrients for the growth and development of fish, shrimp, and crabs, has often adopted the fertilizer and water method, that is, the use of human, livestock and poultry manure and chemical fertilizers to cultivate. plankton. However, due to the long-term and excessive application of farmyard manure and chemical fertilizers, water pollution, bacterial proliferation, serious damage to fish and other diseases and insect pests, and hypoxia have also resulted in low yields, poor quality, and low benefits of aquatic products. Chinese Patent No. 981240283 discloses a preparation method of a rare earth additive and a method for preparing a rare earth phosphate fertil...
