Problems solved by technology

In the prior art, the material and energy of the paddy field ecosystem mainly come from outside the paddy field, such as fertilizer, so the production cost is relatively high; the yield and quality of agricultural products are greatly affected by the surrounding environment and natural conditions, such as drought, pests and diseases, etc. Organic rice The output is not high; the market has insufficient confidence and understanding of organic rice. If the price is not high, the benefits of organic rice planting cannot be reflected. These have hindered the production scale of organic rice to varying degrees, and the market demand cannot be met.

Embodiment 1

[0023] Example 1: is a basic embodiment of the present invention. A production method of high-yield organic rice, its steps are as follows:

[0024] A production method of high-yield organic rice, it comprises the steps:

[0025] A. Paddy field reconstruction: including the selection and transformation of paddy fields, the establishment of anti-escape and anti-violation facilities, the establishment of water intake and drainage systems, the establishment of sun terraces and bait platforms;

[0026] B. Rice cultivation: including seed selection, seedling raising and planting; select varieties with tight spikes that are resistant to pests and diseases, lodging resistance, strong fertilizer tolerance, high quality rice, and can be deeply irrigated; densely planted rice seedlings;

[0027] C. Stocking of soft-shelled turtles, shrimps and fish: including seed selection, seed placement and bait feeding; selection of seedlings with neat specifications, healthy body, no injury and...

Embodiment 2

[0030] Embodiment 2, It is a further embodiment, and what is different from Embodiment 1 is that in the A step, the conditions for selecting a paddy field are: flat terrain, sheltered from the wind and facing the sun, quiet surroundings, easy to care for, sufficient water source, good water quality, unobstructed drainage and irrigation, and fertile soil at the bottom of the field. No silting, solid ridges and no water leakage; paddy field reconstruction includes: excavating ring ditches or excavating field ditches at the same time, heightening and widening field ridges, establishing small ridges that separate the ring ditch from the field surface and facilitating field finishing, and establishing anti-corrosion Escape and anti-violation facilities, establish water intake and drainage systems, and build terraces and bait platforms; ring ditches and field ditches are dug and disinfected to kill harmful organisms and pathogenic bacteria in the ditches, and prevent turtles, shrimp...

Embodiment 3

[0031] Embodiment 3, It is a further embodiment, and the difference from Example 2 is that in the D step, the paddy field water level control: generally keep the field surface water level 3 ~ 8cm during the whole field to transplanting; , the water level of the ring ditch is 15-23cm lower than the field surface, and after drying the field, the water level of the field surface rises to 20-30cm. Half a month before harvesting, the field is dried again, and the water level of the ring ditch drops to about 15-23cm lower than the field surface again; after the rice is harvested Raise the water level to 20-30cm from the field surface. In the D step, when drying the field, make sure that the middle of the field is not sunken, and the topsoil on the edge of the field is not cracked or whitish, and it is appropriate to see that the floating roots of rice are white; As a result, ring-groove soft-shelled turtles, shrimps and fish have adverse effects due to excessive density for a long...

Abstract

The invention relates to a production method of high-yield organic rice and belongs to the technical field of crop cultivation. The production method of the high-yield organic rice is a method for rice and soft-shelled turtle culture and shrimp-fish culture and comprises the following steps of (A) rice field transformation, (B) rice cultivation, (c) soft-shelled turtle, shrimp and fish culture, (D) daily rice management and (E) product harvest. The production method of the high-yield organic rice has the advantages of utilizing ingestion and activities of soft-shelled turtles, shrimps and fish to perform fertilizer increase, weeding and disinsection on a rice field, playing fertilizer applying, weeding, disinsection, disease prevention roles and the like, achieving internal material and energy circulation of a rice field ecological system, reducing dependence degree of the agricultural product yield and quality on the surrounding environments, keeping stable and high rice yield, remarkably improving the economic rice benefit and promoting large-scale organic rice production.

Description

technical field [0001] The invention relates to a production method of high-yield organic rice, which is a method for co-cultivating rice with soft-shelled turtles, shrimps and fish, and belongs to the technical field of crop cultivation. Background technique [0002] The existing high-yield organic rice production technology is derived from the ordinary organic rice production technology, that is, chemically synthesized pesticides, fertilizers, growth regulators and other substances are not used in the entire production process of rice, and organisms and their products are not obtained by genetic engineering. In the prior art, the materials and energy of the paddy field ecosystem mainly come from outside the paddy field, such as fertilizer, so the production cost is relatively high; the yield and quality of agricultural products are greatly affected by the surrounding environment and natural conditions, such as drought, pests and diseases, etc., organic rice The yield is no...
