Terminology, technical indicators and technical requirements for comprehensive cultivation of rice and fishery (General Rules)

The terminology of comprehensive cultivation of rice and fishery includes co-production, rotation, comprehensive cultivation of rice and fish, Qikou, and ditch. The technical indicators mainly include rice yield, ditch pit ratio, net income per unit area, reduction of chemical fertilizer application, and pesticides. Reduced application and application of fishery drugs; technical requirements include stable rice production, standardized aquaculture, and protection of rice paddy ecology. The specific small series will be explained in detail below.

First, the rational use of pesticides

1. GB 11607 Fishery Water Quality Standard.

2. The limit of fishery drug residues in NY5070 pollution-free agricultural products.

3. NY 5071 Guidelines for the use of non-polluted food and fishery drugs.

4, NY 5072 pollution-free food and fishery cooperative feed safety limit.

5, NY5073 pollution-free food aquatic products in the toxic and hazardous substances limited.

6. NY 5116 environmental conditions for rice production in pollution-free food.

7. NY/T5117 technical regulations for rice production without pollution.

8. NY/T 5361 Environmental conditions for freshwater aquaculture production in pollution-free food.

9. SC/T 9101 freshwater pond culture water discharge requirements.

Second, terms and definitions

1. Co-production: The production method of simultaneously planting rice and breeding aquaculture animals in the same rice field.

2. Rotation: In the same paddy field, there are sequential production methods for planting rice and breeding aquaculture animals during the seasons or years.

3. Comprehensive cultivation of rice and fishery: Through the engineering transformation of rice fields, a rice-fishing cooperative rotation system will be constructed. Through scale development, industrial management, standard production and brand operation, stable rice production, new aquatic products and economic benefits can be realized. The application rate of pesticides and chemical fertilizers is significantly reduced, which is an ecological cycle agricultural development model.

4. Sakaguchi: A general term for the season crops, aquaculture animals and their replacement orders for planting and aquaculture in the same rice field.

5. Ditch pit: Ditch and pit excavated in rice fields for aquaculture animal activities, holding, habitat and other purposes.

6. The proportion of ditch pits: the proportion of ditch pits in the cultivated field block to the total area of ​​paddy fields.

7. Field project: Rice field reconstruction for the construction of a rice-fishing cooperative rotation model, including water and drainage system reconstruction, trench excavation, field consolidation, paddy field leveling, anti-fighting, disease prevention and disease prevention facilities construction, machined roads and auxiliary roads Construction and other content.

8. Tillage layer: After years of cultivation and ripening, it forms a unique topsoil of rice fields.

Third, technical indicators

1. Rice yield: The rice yield in the plain area is not less than 500kg per 667m 2 , and the yield per unit of rice in the hilly area is not lower than the average yield of the local rice.

2. The proportion of ditch pits: the proportion of ditch pits does not exceed 10%.

3. Improvement of net income per unit area: Compared with rice single crop under the same conditions, the net income per unit area increased by an average of 50% or more.

4. Reduction of chemical fertilizer application: Compared with rice alone under the same conditions, the application amount of chemical fertilizer per unit area decreased by an average of 30% or more.

5. Reduction of pesticide application: Compared with rice alone under the same conditions, the pesticide application per unit area decreased by an average of 30% or more.

6. Application of fishery drugs: no antibacterial and insecticidal fishery drugs.

Fourth, technical requirements

1. Stabilizing rice production: selecting rice varieties with strong stalks, strong tillering ability, lodging resistance, suitable for local planting; setting minimum target yield of rice according to technical indicators; and ensuring the number of rice planting units per unit area by marginal close planting; Rice straw should be used in the field to promote the restoration of rice field.

2. Standardize aquaculture: select aquaculture species suitable for rice field shallow water environment, disease resistance and stress resistance, suitable for industrial management; combined with the requirements of aquaculture animal growth characteristics, stable rice production and rice field ecological environmental protection, reasonably set the highest aquaculture animal Target yield; the quality of the fish feed should meet the requirements of NY 5072.

3. Protect rice paddy ecology: scientifically set the ratio of rice planting density to stocking density of aquaculture animals; fertilization should be based on organic fertilizer, and less or no fertilizer should be applied; full use of rice paddy natural bait should reduce fishing feed Feeding volume; water discharge from rice fields should meet the requirements of SC/T 9101.

4. Guarantee product quality: water source conditions should meet the requirements of GB 11607, water quality conditions meet the requirements of NY/T5361; environmental conditions of production should meet the requirements of NY5116-2002, rice production process should meet the requirements of NY/T 5117; rice pesticides are the largest The residue limit should meet the requirements of GB 2763. The limit of fishery drug residues and toxic and hazardous substances in aquatic products should meet the requirements of NY 5070 and NY 5073.
