Paddy field breeding five points

Paddy field farming is to raise grain and raise aquatic products in paddy fields, so as to increase the overall economic benefits of paddy fields. The paddy field cultivation is different according to the type of aquatic products cultivated. They are called paddy fish farming, rice paddy farming, and rice paddy farming. Its main technology comes down to the following five aspects. ?

First, breeding paddy field selection?

The paddy fields used for aquaculture should have the following conditions: close to water sources, convenient irrigation and drainage, good water quality, near rivers and harbors; soils are suitable for loamy soil and loamy soil, and can be better utilized in low-lying fields; field blocks are found in 5 to 10 acres. Suitably, it is best to breed on a scale to facilitate the comprehensive utilization of farmland “outside three ditch” and Tiantou natural ponds and channels. ?

Second, field construction?

1. The heightening and strengthening of the Tianshui Tiancang should be more than 40 cm higher than the field surface, and the width of the dome should not be less than 40 cm. The top width of the cultured special aquatic products should reach 80 to 100 cm. ?

2. Open the ditch and dig the pond firstly and open the “kou”-shaped ditch first, and use the excavated soil to reinforce the ridge; secondly, dig “-”, “+” and “well” shape ditch in the middle of the field, and connect with the ditch. The ditch width is 1.5 to 2.5 meters and the depth is 0.8 to 1 meter. In the final excavation of the collection pond, Tiantou Natural Gully Pond is generally used as a breeding pond, and an 80 to 100 square meter can also be excavated at the inlet. Nutrient pools. The pool is used for the temporary raising of fish and crabs in winter and spring, and is used for the temporary avoidance of aquaculture production when rice is put on the field. The total area of ​​the ditch and pond is controlled at 20% to 30% of the paddy field area. ?

3. Anti-escape facilities such as fish or shrimp only, you only need to set anti-escape mesh at the entrance and exit; if you want to raise crabs, cockroaches, etc., you must set up a defense against wall escape or escape. The height on the ground is 50~ 60 centimeters is appropriate, and the ground floor should be buried 15 centimeters and compacted, rounded corners built into the arc. ?

Third, rice transplanting and seed delivery?

1. Rice paddy fields transplanted for cultivation should use high-quality, high-yield rice varieties with long field growth, lodging resistance, and disease resistance. Around the ditch, the planting density can be appropriately increased to exert the marginal effect. ?

2. Seedlings of various types of stocks will be stocked in ponds and ponds within 6 months before they are released. Rice will be transplanted for 5 to 7 days, then seedlings will be planted and then transplanted into the field. The six kinds of comparatively practical breeding modes of stocking are: (1) Main-stocking and raising silver crucian carp. Each acre has a weight of 50 grams of 500 species of fish, with a weight of 50 to 200 grams of 100 species of carp. The highest density of carp is 1 000 per acre. (2) Cultivate fish species. Per mu of stocked summer fish species 0800-10000. (3) The main raising crabs. Five hundred young crabs weighed more than 5 grams per acre, and each of the breeding crabs could be stocked with 1 000 to 2 000 "bean crabs" per kilogram and were equipped with 100 catfish. (4) Mainly raising young shrimp. Each acre stocking and holding eggs 1.5 ~ 2 kg, or 20,000 shrimp. (5) The main turtle is raised. Each acre stocking only weighs 150 to 250 grams of 200 to 300 turtle species. (6) Stocking Macrobrachium rosenbergii. Per-mu stocking shrimp 0.5 to 10,000, and with turtles, squid 100 to 200. ?

Fourth, planting and management?

1. Fertilization and feeding (1) Fertilization. Breeding of paddy fields is mainly based on basal fertilization, with 500 kg of manure per mu, 30 kg of superphosphate, and 10 kg of potassium sulfate. Top dressing 2 or 3 times, each applying 7 to 10 kg of urea and superphosphate. It must be noted that manure can be used only after it has been cooked and cannot be thrown into the pond. (2) feeding. For general aquaculture, larval feed is mainly based on powdered feed, and adult fish are mainly granular feed. For special aquatic products, snails, cockroaches, cockroaches, fly pupae, small trash fish, and animal waste should be fed. The amount of daily feeding was based on the weight of aquatic aquaculture in the field, which was 5% to 10% of adults and 20% to 30% of larvae, and was fed 2 to 3 times a day. Special aquaculture is mainly fed in the evening, and its feeding amount accounts for 60% to 70% of the daily dosage. ?

2.? Daily management (1) Water slurry management. In the early stage, the surface water depth is maintained at 5 cm, and the later stage is 10 cm or more. Every day, attention should be paid to make up for water in a timely manner. Change the water every 2 to 3 days. The best condition for microfluidic aquaculture is to use it. (2) medication. Farmed plots should be used with little or no pesticides. If drugs are used, high efficiency, low toxicity, low residue pesticides should be used. Before the use of drugs, it is required to raise the water level or lower the water level, so that the aquaculture product enters the ditch and pond to avoid the medicine. Spraying or dusting is used to prevent splashing and spreading. (3) Landline. When the field is put on paddock, it is necessary to maintain a certain water level in the ditch and pond, and change the water or keep flowing water every day to prevent shallow water from causing death due to lack of oxygen and suffocation of fish and shrimps. It is also possible to use the intermittent field method for adding water at night in the field. (4) tour observation. Observe more than two times a day along the field, especially on rainy days. Mainly to observe the aquatic food, activities, the situation of rice growth and pest damage, maintenance and escape facilities. ?

Fifth, the harvest?

Reduce the water level before harvesting rice, and concentrate the aquatic products in the ditch and pond. After rice is harvested, the water level can be increased for Putian.

For continued cultivation, other fields should be marketed for aquaculture and fishing or transferred to aquaculture.
