First, the reasons for low efficiency Input and output are inversely proportional to the poor breeding techniques. They did not master the technical aspects of rice paddy farming and the characteristics of the cultured species. They did not deal with the contradiction between rice and breeding objects. Throughout the year, the harvest of the cultivation was very low, and some of them were not even raised. What product. 2. There is no quality of some farmers, due to excessive stocking density, farming technology is not mature enough, although the output has come up, but raised product specifications are small, naturally selling a good price; some products are less meat, poor eyes , Such as crabs, get a good hand to get heavy, fleshy, fat fertilizer, such products consumers naturally like. Those who got their hands fluttering, shell color yellow, rough shell crab certainly will not sell a good price, and even can not sell. 3. There are yields and quality, but all of them are poorly marketed. In recent years, many farmers have failed to understand the market well, follow the trend, and follow the trend to see what people are raising and how to make money. The product is oversupply in the market. For example, in the past few years, the price of crabs was high. Everyone used the ponds, ditches, fields, and lakes to raise crabs. In recent years, the production of crabs soared, and the price of crabs plummeted, causing many farmers to lose everything. . Second, improve the way 1. Reasonable selection of plots to do a good job in field construction (1) Selection of plots Afforestation plots should have adequate water supply, convenient drainage and irrigation, good water quality, no pollution source, good water retention, and a solid and durable structure. . (2) Construction of field projects - First, aquaculture ditch, usually consisting of three parts: ring ditch, field ditch, and fish gill. Circumferential trenches are drilled around the inner side of the field ridge, with a width of 3-5 meters, a width of 2 meters, and a depth of 1-1.5 meters. The "10" shape or the "10" shape in the field ridge is combined with the size of the breeding object and the field size. Well-type field ditch, with a width of 2 to 2.5 meters, a width of 1.5 to 2 meters, and a depth of 0.8 to 1 meter; an excavation at the inlet is a fishing rod with a length of about 10 meters and a depth of 0.5 to 1 meter. , And to keep the ravine connected, the trenches communicate. Gully, which accounts for about 20% - 40% of the total area of ​​rice fields. The second is the irrigation and drainage system, which usually adopts the pattern of high irrigation, low drainage, and irrigation and drainage. The inlet and outlet openings must be blocked with multi-layer polyethylene mesh to prevent the entry of predators and wild fish, so that irrigation can be performed. inferred. The third is to build anti-escape and leak-proof projects. 2. Scientific selection, scientific breeding (1) Selection of rice varieties should be selected for strong disease resistance, less pests and diseases, strong resistance to fertility, resistance to lodging, compact plant type conducive to ventilation, light and large grains, high quality, high yield, long growing period. The variety. Jiangsu and Zhejiang provinces should generally choose Wuyujing No. 3, Yanjing No. 187, and Xuyou No. 3-2. Yun, Gui, Chuan should choose Gangyou 22, II excellent 838 and so on. The south should choose Teyou 63, Shanyou 72, and Shanyou 63. (2) Seedling stocking selection of seedlings with strong physique, large size and orderliness, no disease, no injury, and lively action. The stocking density should be rationally allocated in combination with the farming model, breeding object, and aquaculture area. For example, the stocking density of the main crabs and shrimps will be 600-800 sticks/mu for stocking, 20,000 sticks/mu for shrimp, and 15-20 kg of conventional fish stocks. 3. Keep abreast of the dynamics of market supply and demand, rationally adjust the information of aquaculture species, and understand the supply and demand dynamics of the aquaculture market from multiple sources. Combine their own material conditions, technological levels, and unique characteristics of paddy fields to select names, specialities, and advantages that have broad markets. Variety, the formation of "I have no people, people have me fine" business ideas, good at finding good market prospects for aquaculture species, unexpectedly win. 4. Combining the actual situation, implementing multiple breeding modes in the breeding mode, we must combine our actual situation, discover new ideas, create new content, and vigorously promote the development of rice paddy farming to three-dimensional agriculture, ecological agriculture, and comprehensive agriculture, in the mode of planting From rice-fish type to rice-type, rice-shrimp-type, rice-and-water-shrimp-type, rice-type, rice-type, rice-type, rice-type, rice-fish-type, rice-fish-type, rice-fish The development of various aquaculture models, such as fruit type, has promoted the healthy development of this combination of farming methods. 5. Scientific management, reducing the cost of this branch refers to scientific management, we will think: feeding, water quality regulation, disease prevention and control. These are important, but also a central part of aquaculture, but in order to do a good job of management, we must first understand the ecological habits of the cultured objects, such as its appropriate water temperature range, the water quality requirements are fat or thin, like the bait Which ones, when are the food intake peaks and so on? Knowing this, we can combine its characteristics in farming and create the best living environment for it. Secondly, it is to deal with the relationship between farmed objects and rice, input and output. For example, when we fertilize fields, use pesticides, and cultivate fields, we must consider the preferences and resilience of the cultured animals and try to accept both. The program. For the choice of feed, we should first choose the self-produced feed with wide sources, good palatability, complete nutrition, and low cost, and use some compound feeds when strengthening the fattening.
