Problems solved by technology

The physical and mechanical method mainly uses modern physical techniques such as homogenization, ultrasonication, grinding and osmotic shock to break the cell wall, but the rate of cell wall breaking in homogenization, grinding and other operations is low, and free natural plant growth substances cannot be released, and Grinding method has high production cost due to the constant need for cooling in its process flow; while ultrasonic wall breaking technology is costly and difficult to implement in factory production; the target compound extracted by osmotic shock has high purity, but the extraction rate is low and the operation is troublesome and high cost
In addition, the physical mechanical method will generate a lot of heat during the extraction process due to physical and mechanical effects, which will affect the extraction efficiency
Chemical extraction generally refers to acid and alkali hydrolysis. Acidic or alkaline substances are used to degrade seaweed at high temperature, and high content of alginic acid and its salts can be extracted. However, high temperature and long-term hydrolysis of acid and alkali will Part of the phytohormone causes damage, making it inactive, and the phytohormone cannot be fully extracted
The biological method mainly refers to the microbial fermentation method, which refers to adding suitable microbial bacteria that have been screened to seaweed, and obtaining the extract by fermentation. However, due to the complicated and cumbersome screening process of microorganisms, it is not easy to implement in actual production and application.
[0007] Therefore, the method for extracting natural plant growth substances from kelp in the prior art still needs to be improved. How to extract various growth-promoting active ingredients in kelp to the greatest extent is the key point for the improvement of kelp extraction process

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a fertilizer containing natural plant growth substances and a preparation process thereof. Background technique [0002] There are natural plant growth substances that can promote plant growth in seaweed, which can be used as a growth regulator for plants. Using natural seaweed as raw material, extracting effective substances in seaweed, the produced product contains alginic acid, endogenous plant hormones and other biological substances. Soluble fertilizer of active substances is a new type of green organic fertilizer for agriculture. Kelp is one of the most commonly used raw materials in the production of seaweed-derived biostimulants. [0003] Kelp belongs to cold-water seaweed. It is a large marine brown algae plant that grows in low-temperature seawater. It is cultivated in Liaoning, Shandong, Jiangsu, Zhejiang, Fujian and Guangdong provinces in my country, ...
