Ecological agriculture is a major change in the history of world agriculture. It is a scientific, alternative approach to agriculture that is productive and regenerative. With the development of ecological agriculture, people can protect and improve the ecological environment, prevent and control pollution, maintain ecological balance, and improve the safety of agricultural products.
The practice of ecological agriculture involves building the strengths of natural ecosystems into agroecosystems. The primary goal is to create soil environment and ground conditions. By increasing the diversity of plant growth promoting rhizobacteria and changing the structure and layout of crops, ecological agriculture creates a better living environment for the roots and above-ground parts of plants. The main strategies are as follows.
Building Strengths Above Ground
- Selection of Disease-resistant Varieties
Production crops should be selected with cultivars that are resistant to local plant diseases. Selection of disease-resistant varieties is an effective method of controlling plant diseases. This method is simple, effective and stable. It is the best control strategy promoted by people because there is no chemical pesticide contamination or residue. - Cultivation Layout
Reduce disease impact on crops by growing border crops that are more attractive to specific pests. Establish field boundaries and field areas that are attractive to beneficial insects to improve crop disease resistance. Additionally, choosing a more complex crop rotation pattern can help maintain soil strength and reduce soil erosion.
Building Soil Strengths
- Keeping the Soil Fertile
Soil organic matter and its management are central to creating healthy soils that produce healthy plants with great benefits and good defense mechanisms inside. Regular and large additions of organic matter such as organic manure, compost, and foliage help humans maintain adequate soil fertility. - Increasing the Number of Beneficial Soil Bacteria
Plant–bacterial interactions in the rhizosphere are the determinants of plant health and soil fertility. Free-living soil bacteria that are beneficial to plant growth, commonly referred to as plant growth promoting rhizobacteria (PGPR), can promote plant growth by colonizing the plant root. In general, PGPR work by synthesizing compounds needed by plants, promoting the uptake of certain nutrients from the soil, and reducing or preventing diseases in plants.
Biological Control of Plant Diseases
- Biological control is the control of disease by applying to the host animal or plant a biological agent that prevents disease development by the pathogen. For plant diseases, biological control agents are usually strains of bacteria or fungi isolated from the inner or rhizosphere. With advances in technology, the level of disease control achieved with biological agents is likely to rival that achieved with chemical agents.
