Rice field cultivation technology
Rice fields cultivate eucalyptus and rice and rice are symbiotic. On the one hand, rice fields provide a good place for the growth of quail. The quail livelihood is wide, activities, food intake, and drying range are large. The growth and development are fast and the rate of weight gain is high. On the other hand, wolfberry can be Paddy fields loosen the soil and catch pests. This can greatly reduce production costs and increase economic efficiency. I. Paddy field selection and preparation 1. Paddy fields should be selected for raising rice fields in order to facilitate care, such as the blocks that are closer to the house after the house. At the same time, attention should be paid to the fact that the topography should be low, water conditions are good, water flow is smooth, and drainage and irrigation are convenient. 2. The establishment of anti-escape facilities is useful for burrowing and climbing on all fours. The construction of anti-escape facilities is an important part of raising rice in paddy fields. In the selected rice field, bricks, cement boards, and wooden boards shall be used to construct a wall 50 cm above the ground. The top of the pressure wall shall extend 15 cm inward, and the walls and pressure along the inner wall shall be smoothed. And do a good job in the water and air escape prevention facilities. 3. After the paddy fields are ready to prevent escape from the wall and into the outlet, they should open a trench in the paddy field. It is also possible to use Tanabe’s ditch, which is the place where feed is fed and hibernating. The general sulcus is 3 meters wide, the bottom is wide, and the depth is 1.5 meters. The length is determined according to the area of ​​rice fields and generally accounts for about 20% of the total area of ​​rice fields. Central Tianjian built a beach for pro-spawning and spawning. It is generally north-south, 5 meters long and 1 meter wide. It is 0.8 meters above the normal water level. Second, the release of rice seedlings in rice paddy should be based on reasonable conditions to stocking, to master the stocking density. Lean wastage of water, too close influence the growth and development of earthworms. According to experience, in general, stocking more than 2 years of age, 500 to 800 per mu is appropriate. If you are ready to breed, you can add 50 to 60 5-year-old relatives per acre, with a ratio of 2:1 or 3:2. A large amount of large-sized squid species can be stocked to raise water quality. Third, the feeding of 1 to 2 instars is relatively small, and the feed is mainly composed of fresh compound feed made from aquatic insects, cockroaches, small fish, shrimps, leeches, and fish scraps. More than 3 instars have strong ability to bite, and can use snails, river clams, river clams and other shelled live shellfish as staple foods, and be fed with plant feedstuffs such as soybeans, corn and vegetables, and can also be fed artificially. feed. Feeding and feeding should be done in time, position and quantity. The daily dose is 8% to 12% of its body weight, and it is fed in the morning and twice in the afternoon. IV. Daily management 1. Water quality management Water quality and water temperature have a great influence on the growth and development of earthworms. Attention should be paid to observing the water color, analyzing the water quality, often adding new water, and appropriately controlling the water level. The general water depth should be between 15 and 20 cm. It is also necessary to adjust the water temperature, high temperature season, and without affecting the growth of rice, the paddy field water level can be appropriately increased. 2. In addition to water quality, in addition to water quality, rice field management should always pay attention to preventing escape and damage, and should also pay attention to anti-theft, anti-poisoning, raising rice in paddy fields, and be easily stolen. Special personnel should be responsible for the care. In order to prevent poisoning, do not use pesticides to control pests in paddy rice fields. Fifth, the prevention and treatment of common rickets 1, red neck disease The main characteristics of the disease is the appearance of red spots in the abdomen, swollen throat and neck, muscle edema, slow action. In severe cases, mouth and nose bleeding, inflammation of the intestines, erosion, systemic redness, cloudy eyes and blindness, and soon died. Control methods: 1 Keep water clean. 2 with oxytetracycline, chlortetracycline, chloramphenicol and other antibiotics or sulfa drugs mixed bait feed. 2. Turnip disease This disease is mainly caused by bacterial infections caused by bites or mechanical injuries. The naked eye can see skin spoilage at the extremities, neck, tail, skirts, etc., eroding and forming ulcers. In severe cases, the skin of the limbs rots, the claws also fall off, the bones are exposed, the muscles and bones of the neck are exposed, and the skirts fester. Control methods: 1 Keep the water in the pool clean. 2 Properly intensively reared and fed a good amount of food. 3 Use 10PPM sulfa drugs or antibiotics to dip sickness. 3. White spots appear on limbs, skirts, etc. of leukoplakia, causing epidermal necrosis and partial ulceration. Control methods: 1 thoroughly clear the pond with lime, disinfection, often keep the pool water tender green. 210PPM bleach soaked sickle, or with salt and baking soda mixture Quanchiposa. 4. A cluster of white hairs appears on the extremities, back, plastrons, neck, etc., which can be seen by the naked eye. When the pool water is green, the body of the sickle is also green because the cytoplasm and the stem of the insect body are stained green. Control methods: dip with bleach solution, or dip with salt water.
