Organic fertilizer refers to a type of fertilizer that is used in plant and animal residues to produce or directly use raw materials in nature through biological, chemical, physical and other methods to provide long-term and stable nutrients for the soil, and at the same time improve soil structure and physical and chemical properties. Because organic fertilizers are rich in organic matter and various nutrients, they are widely used in agricultural production.
What agriculture mainly applies organic fertilizer?
1.Organic vegetable farming.
Organic vegetables refer to the process of vegetable production without the use of chemical fertilizers, pesticides, growth regulators and other synthetic substances, but follow the laws of nature, the use of traditional agricultural techniques, to maintain the natural quality and appearance of vegetables. Therefore, organic vegetable cultivation is one of the types of agriculture that mainly apply organic fertilizer.
2.Fruit tree planting.
Fruit tree cultivation is also one of the main types of agriculture where organic fertilizer is applied. During the growth period of fruit trees, a large supply of nutrients is required, and organic fertilizers can provide rich nutrients to promote the growth and fruit development of fruit trees. At the same time, organic fertilizer can also improve soil structure, improve soil water and fertilizer retention capacity, and is conducive to the growth and yield of fruit trees.
3.Tea cultivation.
Tea cultivation is also one of the main types of agriculture where organic fertilizer is applied. The growth of tea requires a rich supply of nutrients, and organic fertilizers can provide the nutrients needed by tea to promote the growth of tea and improve the quality of tea. At the same time, organic fertilizer can also improve soil structure, improve soil water and fertilizer retention capacity, and is conducive to the growth and yield of tea.
4.Ecological farming.
Ecological farming refers to the use of ecological principles to associate animals, plants, microorganisms and other organisms with each other to form a benign ecological cycle system. In this system, the food of farmed animals is mainly natural feed or organic feed, and the main ingredient of organic feed is organic fertilizer. Therefore, ecological farming is also one of the main types of agriculture that apply organic fertilizer.
In short, organic fertilizer, as a natural and sustainable fertilizer resource, is of great significance for the sustainable development of agriculture. In the future, with the continuous improvement of people's awareness of food safety and environmental protection, the application of organic fertilizer will be more extensive.
