Rice-Azolla-fish three-dimensional planting and cultivation system

Abstract

The invention relates to the technical field of ecological agricultural planting and cultivation, in particular to the a rice-Azolla-fish three-dimensional planting and cultivation system. The rice-Azolla-fish three-dimensional planting and cultivation system comprises a planning area and a draining trench and is characterized in that the edge of the inner side of the planning area is divided intoa paddy field area and a supply trench by building a partition wall, and the partition wall is provided with a plurality of water conveying ports at intervals; the paddy field area comprises an inhabiting area and a plurality of planting and cultivation areas, the inhabiting area is located at one optional corner of the paddy field area, partitions are arranged between the inhabiting area and theplanting and cultivation areas, every two adjacent planting and cultivation areas are separated through partitions, the draining trench is dug on the periphery of the planning area and located aroundthe supply trench, the bottom of the draining trench is lower than the bottom of the supply trench, the outer side of the draining trench is provided with a plurality of first draining outlets, and the lateral wall of the supply trench is provided with a second draining outlet. The rice-Azolla-fish three-dimensional planting and cultivation system has the advantages that rice, Azolla and fish cansupply nutrients for one another in a communication manner, and farmer capital investment can be reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of ecological agriculture planting and breeding, in particular to a three-dimensional planting system of rice paddy fish. 【Background technique】 [0002] At present, in order to increase agricultural economic income, farmers have begun to try a combination of various agricultural products and have achieved good results. Ecological farming can protect the ecological environment, facilitate management, and save resources. Among them, fish farming in rice fields is a widely used farming model. At this stage, fish in rice fields do not have a good habitat in harsh environments, resulting in a large number of fish deaths, thereby reducing farmers' economic income. In addition, fish farming in rice fields does not have a large amount of weeds and feed, so the fish eat a lot. A small amount of insects and weeds in the paddy fields alone cannot satisfy the growth of fish, and feeding a large amount of food consu...

Problems solved by technology

[0003] The purpose of the present invention is to solve the above-mentioned existing problems and provide a three-dimensional planting and breeding system for rice paddy and fish, which mainly solves the problem that the circular supply cannot be maintained among rice, red duck and fish. In harsh environments, fish are not easy to die, increasing the comprehensive income of farmers
