The present invention discloses a bait feed specialized for grass carps. Raw materials thereof comprise a vegetable bait feed, an animal bait feed and an additive, wherein the vegetable bait feed comprises soybean meal, peanut meal, glutinous rice flour, pearl barley flour, lotus root starch, kelp powder, spirulina powder, ulothrix powder, reed powder and azolla powder; the animal bait feed comprises betony larva powder, earthworm powder, turmbicula akamushi powder, locust powder, Antarctic shrimp meal and shrimp powder; and the additive comprises stone powder, an amino acid, vitamin E, borax, lemons, betaine and rapeseed oil. The bait feed specialized for grass carps provided by the present invention is reasonable in formula and comprehensive and balanced in nutrition; conforms to foraging habits of the grass carps; can promote growth of the grass carps, and improve immunity of the grass carps; can give out special fragrance and fishy smell to stimulate taste buds of the grass carps; and when the bait feed is fed to the grass carps, the grass carps can quickly come to swallow the special bait feed, so that a waste of the bait feed is reduced and a fish yield is high.

The invention relates to an azolla germplasm resource preservation device, which comprises a base and a cultivation layer frame, wherein preservation boxes for persevering azolla germplasm resources are placed on the cultivation layer frame; a lamp plate component is arranged above the various preservation boxes; water inlet hoses and water outlet hoses all of the various preservation boxes are mutually connected in parallel onto water inlet branch pipes and a return water branch pipe respectively; the water inlet branch pipes and the return water branch pipe are mutually connected in parallel onto a water inlet main pipe and a return water main pipe respectively; a liquid storage tank is arranged in the base, and is connected with the water inlet main pipe and the return water main pipe respectively to form a preservative fluid closed loop; an PLC (Programmable Logic Controller) is arranged in the base, the input end of the PLC is connected with a sensor monitoring unit, the output end of the PLC is connected with the preservative fluid closed loop and an environment control unit to form a closed loop control system, and the PLC is also connected with a GPRS (General Packet Radio Service) communication module. The device has the advantages that independent preservation is realized to prevent the mixing of the azolla resources and the cross contamination of pest and disease damage, a preservation quantity of germplasm resources can be flexibly adjusted, the functions of growth and integrated environment monitoring, adjustment and control are achieved, and the excellent character and hereditary property of the azolla varieties can be preserved permanently.

The invention discloses a selenium-enriched bio-organic base fertilizer for rice planting. The selenium-enriched bio-organic base fertilizer includes 15-20 parts of chicken manure, 8-12 parts of pig manure, 10-15 parts of tea seed cake, 15-20 parts of rice bran, 6-10 parts of rice straw, 2-4 parts of vermiculite, 2-3 parts of chitosan, 4-6 parts of chaff carbon, 2-3 parts of selenium-containing substance, 4-7 of biological bacteria, 1-2 parts of azolla imbricate, 2-3 parts of nitrogen-fixing cyanobacteria, 3-5 parts of humic acid, 1-2 parts of trace elements and 5-8 parts of amino acid fertilizer. Comprehensive nutrition is provided for the growth of rice by adding animal manure and plant fibers such as agricultural waste, rice field soil hardening can be broken, the rice field soil structure is improved, rice field soil organic matter and fertility are improved, rice field drainage is facilitated, rice seedling lodging is prevented, and the selenium content in rice is effectively improved; at the same time, the biological bacteria can ferment the animal manure and the plant fibers such as the agricultural waste, so that waste is recycled, and the environment is protected.
