Rice-turtle-fish-duck four-in-one ecological symbiosis production method suitable for two-crop-a-year paddy field in south

Abstract

The invention relates to a rice-turtle-fish-duck four-in-one ecological symbiosis production method suitable for a two-crop-a-year paddy field in the south. The rice-turtle-fish-duck four-in-one ecological symbiosis production method suitable for the two-crop-a-year paddy field in the south is characterized by comprising the steps of 1 base selection and symbiosis field building, 2 symbiosis field disinfection, 3 rice planting, 4 symbiosis field object (turtles, fishes and ducks) breeding, 5 pest and disease damage control and 6 timely harvest. According to the method, a rice field ecological space is fully utilized, putting time and treatment method of various symbiosis objects are reasonably arranged, the rice, the fishes and the ducks are harvested twice a year, the turtles are harvested once a year, various harvested agricultural products are green and pollution-free and have good economic and ecological benefits. The method is a new green, ecological, energy-saving and efficient recycling agricultural production mode and is especially suitable for requirements of the country for agricultural development at the moment.

Description

technical field [0001] The invention relates to the technical field of high-efficiency agricultural ecological production, and specifically refers to a four-in-one ecological symbiosis production method of rice-turtle-fish-duck that is suitable for paddy fields in southern China twice a year. Background technique [0002] The shallow water environment of rice fields can provide habitats for fish, turtles, ducks and other organisms. The use of rice fields to breed organisms has a long history in my country. The 1,200-year-old rice field fish farming has been selected as "Global Important Agricultural Cultural Heritage" by the Food and Agriculture Organization of the United Nations. The interaction between rice and aquatic organisms and the optimization of ecological processes, as well as the complementary utilization of resources between rice and aquatic organisms, make the rice production system more "clean", the risk and pressure of agricultural production facing pollution a...

Problems solved by technology

[0005] Although the above three paddy field symbiosis methods have many advantages, compared with the present invention, there are disadvantages such as single symbiotic objects, low utilization rate of paddy field ecological space, and low comprehensive economic benefits, and it is difficult to form a real green ecological cycle agricultural production model

For example, soft-shelled turtles, fish, and ducks can all prey on harmful organisms in the field, but due to the biological differences in their respective feeding habits, some harmful organisms in the field under the single symbiotic model will inevitably remain in the field and endanger rice because they do not belong to the feeding range of a certain symbiotic object to grow

Moreover, at present, my country's rice planting has the problems of heavy use of pesticides and chemical fertilizers, serious damage to the ecological environment of farmland, and generally low economic benefits. Farmers' enthusiasm for growing grain has been severely hit, which will endanger my country's food security in the long run.
