Problems solved by technology

The new farming technology that integrates aquaculture and crop cultivation appeared in the 1990s. It is called "Aquaponic" internationally, which means the combined production of aquaculture and crop cultivation. Although it has been developed for nearly 20 years, large-scale There are still technical bottlenecks in industrial application, and most of them are limited to the planting of leafy vegetables and medicinal herbs. The cultivation of large-scale economic trees and fruit trees is less, and most of them are limited to flat farming and utilization. Although there are also some three-dimensional design cultivations , but the three-dimensional mode is basically limited to the shelf type, and its operation and utilization efficiency is not high

Embodiment 1

[0065] The construction of 314 square meters of vertical spiral terraced orchards, such as Figure 11

[0066] 1) The spiral terraced field is built in a mountainous forest without electricity supply. In order to create a space for aquaculture and fruit tree planting, it is planned to adopt the technology of vertical spiral terraced field. The plot used for construction has a diameter of 20 meters and can be built into spiral terraces covering an area of ​​314 square meters. According to the crown shape and tree height of the planted fruit tree species, the storey height is determined to be 3 meters, the width of the terrace is 6 meters, the radius of the central water body is 4 meters, and the total height is 18 meters. According to the principle of constant velocity helix, as figure 1 , built along the 18-meter-high column as an equidistant spiral coil to build terraces.

[0067] 2) Use CAD software to draw a CAD drawing of the overall grid structure, such as figure 2 ,...

Embodiment 2

[0081] Rapid construction of 314 square meters of urban green space, such as Figure 12

[0082] The difference from Example 1 is that the varieties of the cultivation system are landscaping plants or landscape flowers. These plants do not have high requirements for fertilizer and water, and the purpose of cultivation is mainly to beautify and green. It only needs to quickly create urban greening space. Can. It is also suitable to breed fish in the water body as ordinary landscape fish, and the breeding density is also based on the rare breeding method of 30-80 fish per cubic meter.

[0083] The application of this system solves the damage to the original ecology caused by transplanting large trees, and also solves the loss of low survival rate of transplanting large trees, saving huge investment in transportation and transplanting. Using component assembly, you can quickly build a huge green space in the city, and it is a self-circulating, zero-emission, sustainable and low...

Abstract

The invention discloses a spiral terrace type fish and plant symbiotic construction method, and belongs to the field of three-dimensional organic soilless cultivation. The geometrical mechanics principle of a helical line is used in the method, the method is used for vertical terrace construction, and the method is combined with ceramsite substrate culture for three-dimensional mixed planting and interplanting of multiple types of plants; besides, a fish farming water body is used for circulating irrigation, and then an ecological symbiotic system which is free of water changing during fish farming and free of fertilization during planting is formed. The method is used for agricultural efficient three-dimensional production and also can be used for quick construction of urban greening space.

Description

technical field [0001] The invention belongs to the field of three-dimensional organic soilless compound farming, and relates to a three-dimensional spiral terraced field construction technology and a soilless cultivation method for symbiotic fish and plants, that is, a spiral terraced field fish-plant symbiotic construction method. Background technique [0002] According to the planting carrier, modern farming techniques can be divided into soil planting and soilless cultivation, and according to the spatial layout, it can be divided into plane and three-dimensional farming, but most of them are based on fertilizer and nutrient solution technology. In recent years, fish and vegetable symbiosis technology has emerged, using fish farming water as a fertilizer and water solution for circulating irrigation, to achieve the symbiotic ecological effect of growing vegetables without fertilization and raising fish without changing water, but there are still limitations in its applica...
