Abstract

The invention discloses a closed cycle agricultural mode construction method combining sugarcane planting and aquatic product three-dimensional breeding. The closed cycle agricultural mode construction method comprises the following steps of developing sugarcane tip leaves, interplanted crops and crop rotation into feed to feed ecological aquatic products, separating and drying fish manure, mixing and carbonizing with sugarcane leaves and interplanted crop straws to prepare a carbon-based slow-release fertilizer, applying the carbon-based slow-release fertilizer to sugarcanes, preparing discharged wastewater into liquid fertilizer, integrally irrigating water and the fertilizer to a sugarcane field, reducing the chemical fertilizer input, fertilizing the sugarcane field, and increasing the yield. According to the closed cycle agricultural mode construction method, environmental pollution is avoided, generated waste can be recycled, the fertilizer and the like are not needed after a stable circulation system is formed, the production cost is greatly reduced, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for constructing a closed-cycle agricultural model combining sugarcane planting and aquatic three-dimensional cultivation. Background technique [0002] Circular agriculture refers to activities that promote the reciprocal multi-layer and efficient flow of various agricultural resources in the agricultural system, so as to achieve the purpose of energy saving, emission reduction and income increase, and promote the sustainable development of modern agriculture and rural areas. Circular agriculture is an agricultural production method that uses the principle of material recycling and multi-level utilization of materials to achieve less waste production and improve resource utilization efficiency. As an environment-friendly farming method, circular agriculture has good social, economic and ecological benefits. [0003] Sugarcane is an important pillar of my ...
