A paddy field improvement method suitable for co-cultivation of rice and soft-shelled turtles

Abstract

A paddy field transformation method suitable for rice and soft-shelled turtles, characterized in that the specific steps are as follows: 1) Opening a "Z"-shaped ditch in the paddy field; The ~4m machine-cultivated road is connected to the paddy field block, and the machine-cultivated roads of two adjacent rice-field blocks are arranged in opposite directions; 3) There are water inlets and drains on both sides of the dyke near the machine-grown road, and the water inlet and the drain are formed into Oppositely arranged, the drainage outlet is buried at the lowest point of the ditch, and the drainage outlet includes a high water level drainage outlet, a low water level drainage outlet and a bottom drainage outlet, and is regulated by a water level regulating pipe. The paddy field improvement method of the invention is suitable for the co-cultivation mode of rice and soft-shelled turtles, has good convenience and is beneficial to large-scale production.

Description

Technical field [0001] The invention involves a transformation method of rice fields, especially a rice field transformation method suitable for rice fields. Background technique [0002] With the continuous innovation of modern agricultural technology, agricultural planting technology and aquaculture technology are combined and rationally assembled. The shallow water environment of rice fields is used to plant rice, while breeding of aquaculture. First, the waterfield water resources and weedsResources, small aquatic animal resources, insects, and other substances and energy are more fully used by aquaculture; second, through the foraging of the aquaculture aquacted aquaculture, to achieve draft, insect extinguishing, sparse soil, and gaining weight in rice fields.The purpose of realizing rice to increase production, quality increase, and aquatic products income and no harm; thereby obtaining a three -dimensional and healthy agricultural model that integrates economy, ecology an...

Problems solved by technology

[0010] However, the above paddy field models such as "one", "ten", "hui" and "tian" are all improved from the basis of paddy field fish farming, and are generally only suitable for 1~5 Mu-scale small-area farming mode; secondly, when the above-mentioned modes are used in series or in parallel for large-area co-cultivation of rice and soft-shelled turtles, it is easy to consume land, water, and materials, and the convenience is poor.

[0011] The "me" type paddy field pattern, although the series and parallel connections can bring about the large-scale co-cultivation of rice and soft-shelled turtles, but because of the water pipes buried under the machine-cultivated road, it is easy to settle and block, which is not conducive to the replacement of water flow. The problem of large consumption of pipeline materials

[0012] In addition, for the rice-turtle co-cropping model, if the surface of the turtle ditch is hardened, the purpose of ecological breeding of soft-shelled turtles will not be achieved, nor will it meet the requirements of wild and organic soft-shelled turtle farming.

However, in the complete adobe ditch type, rice and soft-shelled turtles have been co-cultivated for a long time. Because soft-shelled turtles have the characteristic of drying their backs, in the process of looking for a place to bask in their backs, it is very easy to cause damage to the edge of the ditch and the ridge, and it is easy to cause the banks on both sides of the turtle ditch to collapse. It makes the turtle ditch wider and wider, which is not conducive to the rotation of rice
