At present, the cultivation of organic agricultural products in China needs to detect the basic conditions such as planting environment (mainly soil and atmosphere) and planting water source. Scientific monitoring by relevant units can ensure that the planting environment and basic conditions do not contain pesticide residues and chemical pollution, and avoid affecting the quality of organic agricultural products in the biological circulation system.
2. Choose excellent varieties or seedlings.
Planting organic agricultural products needs to ensure the quality of varieties and adapt to the planting environment. The selection of varieties should conform to the local natural conditions and climate characteristics. Organic planting needs to reduce the use of biological agents, so seeds or seedlings need to be self-resistant to pests and diseases, and have high self-healing and activity. Before sowing, it is necessary to select seeds by bolting, so as to avoid the application of unqualified seeds as much as possible. If necessary, seed can be urged in advance to ensure the survival rate of seeds.
3. Take a variety of planting methods such as crop rotation and three-dimensional planting.
Organic agriculture requires high soil quality, and the soil environment in some planting areas may not be suitable for planting organic products at the initial stage. Therefore, we can improve the soil environment, enhance soil fertility and permeability through crop rotation, and then plant products that meet the organic planting conditions after soil monitoring. After the end of the planting cycle, crop residues, roots and other substances should be removed in time to reduce the occurrence of pests and diseases in the planting process in the coming year. There is a certain gap between the output of organic planting and traditional planting. Growers can carry out three-dimensional planting by interplanting crops, which can effectively improve planting income and reduce pests and diseases through different microbial substances carried by plant roots. Organic three-dimensional agricultural technology has been applied and popularized in many parts of the country.
4, organic agriculture planting fertilization technology
Fertilization is also a key link in organic agriculture. The selected fertilizers are mainly biological bacterial fertilizers and various organic fertilizers, and artificial chemical synthetic fertilizers are prohibited. Growers can choose human and animal manure and straw as fertilizer, or make their own microbial enzymes to enhance the content of trace elements in the soil and ensure the growth demand of crops. Among them, bio-organic fertilizer is a widely used organic fertilizer product. When ploughing the soil before planting the product, it is necessary to use base fertilizer to ensure the fertilizer supply at the early stage of crop growth. After the crops grow to a certain extent, it is necessary to apply topdressing or organic foliar fertilizer to ensure the fertility supply for the continued growth of crops.
