Recently, some growers asked Xiaobian, " I want to know how to breed crabs in rice fields. The rice that I contracted has more than 100 mu. It is difficult to cultivate the technology. How much can I invest? What kind of income can I get? Is there any support for the policy? At present, the governments of various localities have certain subsidies for the comprehensive cultivation of paddy fields. Some of them use subsidies for agriculture-related funds. Some of them are financial special subsidies. There is no unified subsidy model. However, this year, a unified subsidy for high-standard farmland, rice or shrimp comprehensive breeding or rice and crab comprehensive breeding, if you want to apply for high-standard farmland construction subsidies, you must squeeze the project into the high-standard farmland project, it is recommended to go to the local The Agriculture Bureau consulted that there should be subsidies if it can be classified as a high standard farmland. The following small series will talk to you about the cultivation techniques and income analysis of rice and crab. I. Rice paddy area Raising rice fields should be easy to care for, such as the fields near the house in front of the house. At the same time, it should be noted that the terrain should be lower, the water source conditions are good, the water flow is smooth, and irrigation and drainage are convenient. The area of ​​a single paddy field is generally more than 5 acres. Second, rice field transformation 1, trenching Excavation of the annular groove, the width of the ditch is 3-4 meters, the depth is 0.8-1 m, and the area of ​​the ditch accounts for 10% of the paddy field. 2. Building and field leveling The use of circular trench excavation and land leveling will increase the height, widen and strengthen the field, and the field will be 0.6-0.8 meters higher than the field. 3. Anti-floating facilities There should be an escape net on the paddy outlet and the rice field. The anti-escape net of the drain should be a 20-mesh mesh. The anti-escape net on the field can be made of cement tile and anti-escape plastic film. The anti-escape net is 0.4 meters high. 4. Drainage and drainage facilities The inlet and outlet are located at the two ends of the paddy field. The inlet channel is built on the field at one end of the paddy field. The inlet is filtered with 20 mesh long mesh bags to prevent the entry of the enemy's biological waterproof flow. The outlet is built at the other end of the rice field. The lower part of the ditch. Third, water planting The water can be planted in the ditch, such as Elodea, Hydrilla verticillata, and bitter grass. It is planted every year from January to April, and the coverage rate is more than 60% after growing. Fourth, rice planting It is advisable to choose late rice varieties with strong fertility, lodging resistance, strong disease resistance and excellent quality. Planted in the normal way, no drugs. Five, crab stocking The stocking time is from December to February of the first year. The breeding density per acre is 1,200, and the specification is 80-100/kg. The crab seedlings are better cultivated by themselves. It is necessary to choose high-quality crab species with uniformity, uniform color, complete limbs, and strong disease-free. Sixth, benefit analysis 1. Output value: According to the rice yield of 400 kg per mu, the unit price is 6 yuan/kg (take ecological breeding, rice price increase), the output value is 2,400 yuan; the river crab is 100 kg per mu, the unit price is 100 yuan/kg, and the mu income is 10,000 yuan. The total output value is 12,400 yuan. 2. Cost: The cost of rice planting is 711 yuan per mu (including seeds, fertilizers, pesticides, machinery, labor, etc.), and the cost of river crab farming is 4,500 yuan per mu (including seed, bait, artificial, anti-escape facilities, water plants), total The cost is 5,211 yuan. 3. Benefits: The average net income of rice and crab comprehensive breeding can reach 7189 yuan. The frequency of the ultrasonic energy meter is 1 megahertz (1 million Hz / s), the direction is accurate, and the penetration is strong. Through the three major effects of sound waves (mechanical, warm, physical and chemical effects) on various parts of the human body, to achieve the role of massage relaxation.
