During artificial breeding, the feedstuffs are mainly wheat bran, fish meal, peanut cake and clam shell powder. Fish meal and clam shell contain more calcium components, but the content of astaxanthin is very small, which cannot meet the needs of crayfish in the breeding process. Demand
In the paddy field farming mode, transplanting water plants such as water hyacinth and water peanuts in rice fields is conducive to increasing the content of astaxanthin in crayfish, b

Embodiment 1
[0022] A method for cultivating rice and shrimp with high astaxanthin content, comprising the following steps:
[0023] (1) Soil treatment: After the rice and shrimp farming field is harvested in summer, apply farm organic fertilizer at an amount of 350-380kg per mu. After plowing, spray the soil with 1.8% abamectin 1200 times dilution and let it dry for 12 days;
[0024] (2) Rice and shrimp breeding field: The rice farming field is divided into a breeding protection dam, a rice and shrimp breeding ditch, and a rice planting area. There is 1 water pump; between the breeding protection dam and the breeding ditch, there are two layers of nylon isolation net with mesh 40, the net height is 0.8-1m, the distance between the two isolation nets is 12-15cm, and the outer isolation net is close to the inside of the breeding protection dam;
[0025] (3) Transplanting aquatic plants: spray 40ppm chlorine dioxide solution on the rice and shrimp breeding ditch and the breeding protection d...
Embodiment 2
[0038] Present embodiment 2 is compared with embodiment 1, and step changes in the following aspects:
[0039] Step (3) Transplanting aquatic plants. The planting area of the aquatic plants is 28%. The types and planting ratios are as follows: scallops account for 28% of the total aquatic plants, duckweed accounts for 47%, and spirulina accounts for 38%.
[0040] Step (4) Shrimp seedlings are put in, the size of the said shrimp seedlings is 4cm, and the amount of 2800 shrimps is put in.
[0041] Step (5) feeding and management, the rice and shrimp feed, the weight of each prepared ingredient is as follows:
[0042] 34 parts of corn flour, 23 parts of soybean meal, 13 parts of shrimp shell powder, and 9 parts of Haematococcus powder.
[0043] Step (5) Feeding and management, the method of feeding rice and shrimp feed is:
[0044] Put the rice shrimp feed into the feed basket. 14 days after the shrimp seedlings are put in, put the feed once every 7 days, and put 9kg each time....

Abstract
The invention discloses a high-astaxanthin rice shrimp breeding method. The method is characterized by comprising the following steps that (1) soil is managed, farmyard manure is applied, and avermectins is adopted for soil treatment; (2) a rice shrimp field is divided into a breeding protecting dam, a rice shrimp breeding ditch and a paddy rice planting area, and protected with two layers of nylon nets so as to reduce rice shrimp escaping; (3) water plants are transplanted at a water surface area ratio of 25-30%; (4) young shrimps of 2-4 cm long are put into the field at the amount of 2400-2800 per mu, water in the rice field is changed through a water pump regularly, and the oxygen content in the water are increased; (5) for breeding management, rice shrimp feed is prepared, the adding amount of the rice shrimp feed is changed according to the growth phase, and the rice field is sprayed with a multi-bacterium biological agent. Through the preparation of the rice shrimp feed and the feeding method, the high-astaxanthin rice shrimp breeding method can improve the water quality environment of the rice field, promote the content improvement of astaxanthin in the rice shrimp, and meanwhile improve the yields of the bred rice shrimp and the rice. The high-astaxanthin rice shrimp breeding method has the advantages of being simple, practical and obvious in effect.
Description
technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a rice and shrimp breeding method with high astaxanthin content. Background technique [0002] Crayfish, also known as Procambarus clarkii, red crayfish and freshwater crayfish, feed on aquatic plants, algae, aquatic insects, animal carcasses, etc. Shrimp meat is also rich in magnesium, zinc, iodine, selenium, etc. Magnesium is beneficial to the heart Activity has an important regulatory effect, can protect the cardiovascular system, and can also expand the coronary arteries, which is beneficial to the prevention of hypertension and myocardial infarction; crayfish contains astaxanthin, which is a strong antioxidant with antioxidant properties. The effects of anti-tumor, cancer prevention, immunity enhancement, and vision improvement have promoted the third wave of preventive drugs. Crayfish itself does not produce astaxanthin, but mainly obtains astaxan...
