Ten Modes Of Ecological Recycling Agricultural Development

The development of ecological recycling agriculture is the fundamental requirement of sustainable agricultural development, and is also the need to enhance the competitiveness of agriculture and better realise the multiple functions of agriculture. Shandong as an agricultural province, in recent years, continue to strengthen the intensive and economical use of agricultural resources, vigorously strengthen the prevention and control of agricultural surface pollution, and actively guide and support the relevant technology, mechanisms and models of innovation, the province's ecological cycle of agricultural development has achieved significant results. 22 September, the province's ecological cycle of agricultural field promotion and "three autumn" production work conference held in Feixian. Feixian held at the meeting released the ecological cycle of agricultural development in Shandong Province, ten models.

Wheat and corn stalks full amount of fine field ecological recycling development model

Based on the wheat-corn rotational cropping system in Shandong Province, the integrated technology of agro-machinery-agro-technology integration is adopted, and two "one-stop" intensive production operations are carried out through no-tillage sowing of wheat straw and rotary ploughing (or deep ploughing) sowing of maize straw, which releases nutrients from rotting straw and increases soil organic matter, thus realising the ecological recycling of straw. Straw ecological recycling.

Ecological recycling development mode of straw fertiliser utilisation

Focusing on straw fertiliser utilisation, collecting all kinds of crop straws, building regional straw fertiliser treatment centres, realising closed-loop development from straw collection and transportation, harmless treatment to fertiliser field application, and realising ecological and economic win-win situation.

Straw base material utilisation ecological cycle development mode

Focusing on the outstanding problems of incomplete industrial chain of resource utilisation of agricultural and forestry wastes such as straw and fruit twigs, and the large amount of idle land such as collapsed wasteland in mining areas, we take straw substrate utilisation as a breakthrough, carry out factory and intelligent cultivation production of edible fungi, realise high-quality and efficient utilisation of straw, and form the ecological cyclic development of the agricultural fungus industry.

High-value use of straw ecological cycle development mode

Based on the physical and chemical characteristics of crop straw, through coal chemical, petrochemical and biomass conversion and utilisation technologies, the production of high-value refined products; the use of straw and forestry waste raw materials combustion to generate steam power generation; the natural fibre of agriculture and forestry as the raw material, magnesium oxide inorganic gel material as the binder and modification of the auxiliaries mixed with the mixing of inorganic fibre man-made panels made of paving and low-carbon process.

Fertiliser and pesticide reduction ecological cycle development model

Landscape ecological design for concentrated and continuous grain fields and orchards, based on the planting of functional plants (trapping plants, flower-exposing plants and green manure plants, etc.), combined with intelligent monitoring (digital measurement and control system for pests and diseases and agricultural conditions), release of natural enemies (parasitic wasps, predatory natural enemies, etc.), biological agents (biopesticides, bacterial fertilizers, etc.), physical and chemical attraction and control (psychedelic agent, sex attractant, etc.), and other key technologies, so as to enhance the ecosystem species and diversity to improve its ability to regulate itself. Enhance the diversity of ecosystem species to improve their self-regulation ability, form the ecological closed loop of "ecological agricultural products - crops - functional plants - reuse", and realise the high-quality development of agriculture by reducing medication and weight loss in farmland, improving quality and efficiency.

Livestock and poultry manure resourceful use of ecological cycle development mode

Based on the principle of full utilisation of farming manure and friendly agricultural environment, we have established livestock and poultry manure resource utilisation models for different application scenarios according to different farming types, farming scales and utilisation pathways. Decentralised farming to build a light and simple treatment, putrefaction fertiliser, local consumption and utilisation mode, large-scale farming to build a centralised high-efficiency treatment - fertiliser utilisation and three swamps comprehensive utilisation and other ecological recycling modes, to realise the green, high-quality and sustainable development of breeding and raising.

Eco-cycling development mode of integration of breeding and raisingTaking the multi-level efficient recycling of agricultural resources as the core, optimising the supply of feed grains through silage/yellow silage straw, effectively responding to the contradiction between the continuous expansion of the demand of the livestock product consumption market and the rising cost of feeds, promoting the close convergence of planting, breeding and processing, realising the clean production of the breeding industry, the improvement of the quality of planting industry and the increase of its efficiency, and the deep processing of green agricultural products, and building a green eco-cycling mode based on the integration of the whole industry chain of farming and breeding and processing. Closed chain.

Ecological cycle development mode of pond breeding tail water use

Carry out engineering transformation of centralised and continuous ponds, use pond breeding tail water for irrigation, or use combined purification systems to use nitrogen and phosphorus produced during the breeding process as fertiliser for crops, and return the purified breeding tail water to the aquaculture area, forming a "breeding - planting - reuse" closed loop, and achieving the goal of "breeding - planting - reuse". The closed loop of "aquaculture - planting - reuse" is formed to achieve the water-based recycling of aquaculture tail water or discharge in compliance with the standards.

Multi-trophic level offshore integrated aquaculture ecological cycle development model

Based on the characteristics of offshore fish, shrimp, shellfish, algae and ginseng three-dimensional aquaculture industry, with the principles of environmental ecological friendliness and high quality and efficiency of fishery, and based on the reasonable matching within the aquaculture space, mutual benefit of aquaculture organisms' ecology and control of aquaculture capacity, form an ecological development model based on the recycling of materials and energy in aquaculture waters, so as to realise the purpose of making full use of the marine aquaculture space, giving full play to the function of the fishery's carbon sinks, and enhancing the aquaculture benefits.
