Biomass fertilizer


There are different ways to prepare plant stock solution

1) About 70% of the raw materials of liquid fertilizer on the market are produced by low-temperature hydrolysis of biomass, such as biogas slurry, in which the nutrients are unstable, easy to decompose and volatilize, and some harmful substances are easy to remain;

2) About 25% of the raw materials of liquid fertilizer on the market are produced by pyrolysis of biomass at medium and low temperature. For example, the production temperature of the pyrolysis liquid is 450-650 ℃. The tar content in the pyrolysis liquid is generally high. It is difficult to decompose and has a pungent taste when sprayed on the plant leaves. The beneficial components in the plant liquid are volatile and the effect will be weakened;

3) The plant liquid in this project is pyrolyzed at 1100 ℃, which can effectively decompose the plant tar, and finally form stable carbon, hydrogen and oxygen compounds such as phenol, aldehyde and ketone, which are stable in composition and easy to be absorbed by plants;

The refining methods of plant stock solution are different

85% of the liquid fertilizer products in the market can not be customized, and the key 2-3 indicators are consistent according to different plant liquid ratio. In order to control the concentration ratio of the required components, the project team invented cyclone separation and multi-stage extraction technology, which can control the anchored compound components in the required range, so as to achieve the stability of pest control.

To sum up, combined with the market situation, this achievement has the following advantages in competition with domestic similar products after industrialization:

1) Increasing the pyrolysis temperature of plant stock solution can decompose many harmful residues in plant stock solution, and improve the stability of beneficial compounds for pest control in plant stock solution, so as to improve the control effect;

2) The production technology of the plant liquid nutrient fertilizer is advanced, the product performance is stable, and the indexes are equal to or surpass the domestic similar products;

3) The formulation for different plant leaf pests control is more accurate, more effective and more competitive in the market.

Market analysis of three products

Plant liquid nutrient fertilizer has been successfully applied to Qixia Apple, Zhanhua Dongzao, Qingdao Xanthoceras sorbifolia, Nangong waxy corn, soilless vegetables and so on. It has obvious antibacterial, bactericidal and pest repellent effects, reduces pesticide dosage and soil pollution effect, and can realize the integration of water and fertilizer, high efficiency and water saving, promote the root and seedling growth of agricultural and forestry crops, resist lodging and improve crop resistance It can also improve the photosynthesis of crops, increase the yield and early maturity of crops, improve the internal and external quality of agricultural and forestry products, and significantly improve the yield and quality of crops. With the improvement of people's requirements for the quality of agricultural and forestry products, the maintenance of urban road greening plants also needs pest control, strong seedlings and green enhancement. The characteristics of high efficiency, low consumption and high quality of plant liquid nutrient fertilizer will be recognized more and more, and the market will be larger and larger.

Qingdao is a city short of water. The development of the industry will help to save water in agricultural and forestry irrigation, reduce the use of pesticides, reduce the use of chemical fertilizers, protect the environment, protect the soil, and protect the health of citizens.

Environmental impact of the project

The project has no waste water and waste gas discharge, all of which are closed cycle process, meeting the requirements of environmental protection. In this project, the world's leading liquid segmented extraction technology is adopted. The plant liquid is separated and extracted by centrifugal cyclone to obtain different concentrations and components of plant original liquid.
