Three-dimensional comprehensive planting and breeding method for rice field

Abstract

The invention relates to a three-dimensional comprehensive planting and breeding method for a rice field. The method comprises the following steps of digging surrounding ditches on the inner sides ofridges of the rice field; planting trees on the ridges to form a tree heat insulation layer extending in the extending direction of the ridges; planting submerged plants in the ditches to form a submerged plant heat absorption layer; planting floating plants in the ditches to form a floating plant heat resistance layer; planting rice in the inner areas of the surrounding ditches to form a herbaceous heat insulation layer; freely raising aquatic animals in the rice field; when the growth of the aquatic organisms satisfies harvesting conditions, harvesting the corresponding aquatic organisms; after the rice is mature, harvesting the rice. The planting and breeding method can prevent excessive ditching and increase the yield per mu of the rice field and the economic benefit.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a three-dimensional comprehensive planting method for rice fields. Background technique [0002] The three-dimensional comprehensive planting and breeding of rice fields not only produces grain, but also increases the income of rice farmers. It kills two birds with one stone, and also provides an economic guarantee for the sustainable production of rice. It is the modern development of my country's classic agronomy. Especially in recent years, the comprehensive cultivation of paddy fields has developed in a blowout style. Taking crayfish in paddy fields as an example, at present, the provinces with an area of ​​more than 1 million mu are Hubei, Hunan, Anhui, Jiangsu, and Jiangxi. These five provinces are also the largest crayfish in my country. core production area. However, in the process of comprehensive paddy planting and breeding development, some problems also ...

Problems solved by technology

One is to implement the connection of ponds and fields, replacing the water body of ditch with pond water to provide habitat for crayfish, but most of the rice fields are not adjacent to ponds, and it is difficult to realize the connection of ponds and fields

The second is to dig deep trenches, that is, to increase the depth in a limited trench and exchange space for area, but digging deep trenches is difficult to achieve in most rice fields, because the edge is easy to collapse when the depth increases, and a large amount of silt enters the trench for filling
