Description

The composition structure of intelligent release organic fertilizer

The invention relates to the field of agricultural technology, specifically a composition structure of intelligent release organic fertilizer containing different fertilizer components.

As traditional agriculture increasingly adopts industrial production methods, the use of pesticides and chemical fertilizers can reduce the manpower input into agricultural production. Today's agricultural production is only to obtain the highest economic benefits in the shortest time, and large amounts of chemical fertilizers and pesticides are often used in the production process. Traditional farming methods have seriously polluted the environment and endangered human health due to the excessive use of chemical fertilizers and pesticides to increase productivity. The long-term use of chemical fertilizers and pesticides in large quantities has not only led to soil acidification, salinization and soil fertility decline. , also destroyed water resources and ecological environment, seriously polluting our quality of life.

Organic agriculture is a type of sustainable agriculture. It avoids the use of chemical fertilizers and synthetic agricultural chemicals, and cooperates with plant rotation systems to recycle distiller's grains or agricultural waste, as well as natural ores containing plant nutrients, to maintain Farming methods for agricultural production.

In recent years, people have become more aware of environmental protection and healthy diets. In order to maintain environmental quality and living standards and ensure sustainable land cultivation, organic agriculture has gradually received attention from farmers and knowledgeable people, and more and more people are investing in the cultivation and development of organic agriculture.

At present, the country has good conditions for precision agricultural production. We not only need to focus on the high quality of the products grown, increase yields, shorten the production period, good weather resistance, and resistance to pests and diseases, but we also need to work hard to keep the land used for planting better and more suitable for planting, so as to achieve high-quality production and a sustainable farming method.

This is because leaving the soil fallow and giving it a recovery period will cause a window period for harvesting and seriously damage agricultural income. For example, perennial fruit trees cannot obtain the nutrients needed for growth through crop rotation.

On the other hand, plants have their most suitable climate and environment for growth, and their responses to soil characteristics are also different. Since plants themselves have exclusivity problems, they inhibit the growth of other plants through the natural selection nature. The traditional rotation method can mainly avoid the one-sided and rapid consumption of soil nutrients. Because different crops have different requirements for nutrients, crop rotation can make balanced use of soil nutrients, and other crops can also be selected to improve soil quality.

Therefore, we propose a composition structure of intelligent release organic fertilizer to solve the above problems.

The purpose of the present invention is to provide a composition structure of an intelligently released organic fertilizer to solve the problem raised in the above-mentioned background technology that due to the current fallow period of the soil and the recovery period given to it, a window period of harvest will be created, which seriously damages agricultural income and makes it impossible to obtain the nutrients required for growth by crop rotation.

Leave about 10-20 cm between the top surface of the organic fertilizer composition structure 10 and the pit entrance, and then plant the seedlings into the pit. And it is located above the organic fertilizer composition structure 10. After backfilling the soil, water is poured until a small amount of water overflows on the surface of the pit.

Since plants absorb the same nutrients in succession, the nutrients in the soil will be lost quickly, and eventually a large amount of chemical fertilizers must be used to supplement them, which will increase the amount of chemical fertilizers used. The base fertilizer unit contains at least wine lees, bean dregs, palm ash, seaweed extract, rice husks, straw, fish bones, ore and recycled starch. The base fertilizer unit is used to decompose toxins in the soil and improve the soil quality.
