Rice paddy soil muddy technical points
Rice paddy fields can not only rationally use limited resources, reduce farming costs, but also maintain ecological balance and increase farmers' income. The main technical measures for the breeding of loach in rice fields are described below. Plant extracts are based on plants as raw materials. According to the needs of the use of the final product extracted, through a physical and chemical extraction and separation process, one or more effective ingredients in the plant are obtained and concentrated, without changing the effective ingredients.

I. Selection of raising rice fields
The paddy fields with good water source conditions and easy management should be selected. The soil with viscous soil, high maturity and high fertility should be preferred.
Second, the transformation of rice fields
1. Ditch type. It is a kind of paddy field where rice is cultivated on a ridge and muddy is cultivated in a ditch. In general, it is rare to use a simple ridge-type mud-retaining system, and both the sloping and ridge-ditch methods are used.
2. Tiantang style. It is a cultivated rice field pattern where fish ponds and fish ponds are connected to paddy fields in low-lying areas inside or outside the rice fields. With this style, the loach can freely move and feed between fields and ponds. The area of ​​fish ponds accounts for 10%-15% of the area of ​​paddy fields and the depth is 1-1.5 meters. The ponds and fields are connected by a ditch, and the ditch width and ditch depth are all 0.5 meters. Pads should be installed at the entrance and exit of rice fields to prevent muddy water from escaping with water. In order to prevent the muddy from escaping, the paddy field must be reinforced and the bottom should be reinforced.
Third, the stocking of seedlings
Loach generally starts stocking 10 days after rice is transplanted. Seed size specifications are 4-8 cm in length, with an average of 60-80 kg per acre.
Fourth, field management
The paddy fields that are stocked with mud shall be responsible for management, and use high-efficiency, low-toxicity pesticides for the pest control of rice, which can be applied according to the conventional dosage, and when the pesticide is sprayed, the method of applying deep water and spraying the nozzle upwards shall be adopted. Since muddy loaches inhabit mud, in general, it is much safer to use pesticides and fertilizers in the farming of loachy rice fields than in paddy fields to cultivate other fish. However, the use of toxaphene, carbofuran, quick lime, and tea cakes must be prohibited. During the hot season, the field is properly filled with deep water to adjust the temperature of the water to prevent the mud from burning. In peacetime, it is necessary to constantly check and repair the facilities and timely plug loopholes to prevent poultry from eating mud.
V. Feeding management
1. After the seedlings are stocked, the water depth of the paddy field is kept above 5 cm. In hot seasons, the water depth should be maintained at 10 cm or more. At the same time, we must keep the field fresh.
2. In addition to applying base fertilizer and topdressing fertilizer, they should also feed bait. The main baits are wheat bran and rice bran. It's best to feed in the night and make a full investment. Cloudy weather and low atmospheric pressure should reduce the amount of feeding.
Six, disease prevention
Ten days before stocking, seedlings made of 20 kg of lime were used to disinfect the whole field of lime milk. The bleaching powder was used to disinfect once every month during the breeding process. If there are rotten fleas, red peony disease, and enteritis in the loach, use 0.5 kg of soot root per acre of rice field to put it on the four corners of the rice field, press it with stones, and soak in the paddy field water. If there is a bubble disease, immediately after the new water is added, the water will be splashed with 4-6 kilograms of salt per acre of water.
Seven, the harvest method
Loach is difficult to catch because it lives in mud. However, according to the characteristics of loach in different seasons, the following methods can be used for harvesting: in winter, piles of pigs or cow dung are piled in the deeper layer of the mud in the field for composting. Looting is concentrated in the dung heaps for multiple fishing operations. In the spring, the inlet and outlet openings are opened and bamboo rafts are installed. The loach naturally enters with the water. In the autumn, all the field water is drained and re-sunshine, and it is dried until the field is hard. A thin layer of water is poured in, and a large amount of mud will come out of the mud and be captured.
1. According to the content of active ingredients, it can be divided into three types: effective monomer extract, standard extract and ratio extract;
2. Divided into glycosides, acids, polyphenols, polysaccharides, terpenes, flavonoids, alkaloids, etc. according to ingredients;
3. According to the product form, it can be divided into vegetable oil, extract, powder, lens, etc.
4. According to the purpose, plant extracts can be divided into natural pigment products, traditional Chinese medicine extract products, extract products and concentrated products.
There are several classifications of some of the best-selling plant extracts in the world. For example, Rhodiola, Ginkgo biloba, Ginseng extracts are used in the field of brain strengthening, nourishment, and prevention and treatment of Alzheimer's; polypeptide extracts of green tea, Citrus aurantium, apple, and bitter gourd Used in weight loss, lowering blood sugar and preventing diabetes; Paclitaxel, tea polyphenols, theanine, bioflavonoids, such as lycopene, anthocyanins, etc. are used in natural anti-cancer fields; licorice, garlic, astragalus, soybean extract Used in the field of human immune system.
