Problems solved by technology

In addition, in recent years, algae such as Enteromorpha have flooded coastal areas such as Yantai, Weihai, and Qingdao, seriously polluting the environment and even affecting coastal landscapes.
[0006] At present, most manufacturers at home and abroad mainly use chemical hydrolysis to produce seaweed fertilizer, that is, use strong acid and strong alkali to treat seaweed under severe conditions of high temperature and high pressure. lots of active ingredients
In addition, there is no report on compounding seaweed with other plants to prepare organic fertilizers

Embodiment 1

[0019] Embodiment 1 prepares seaweed organic fertilizer

[0020] Proceed as follows:

[0021] (1) Remove the sand from the seaweed, dry it in the sun, make the water content less than 10% (mass percentage), and pulverize it to obtain seaweed powder (the particle size of the seaweed in the seaweed powder is not more than 0.5cm×0.5cm), and then mix the seaweed powder with Mix water with a mass ratio of 1:20, adjust the pH to 3 with 0.1mol / L hydrochloric acid, adjust the temperature to 50°C, and ultrasonically break the wall (breaking time 10min, ultrasonic power 125w); after breaking the wall, use 0.1 mol / L NaOH solution to adjust the pH to 5, and then use ultrasonic extraction for 50 minutes (ultrasonic power 150w), filter to obtain seaweed extract, concentrate (control the concentration temperature at 45-50°C, and keep the concentrated steam pressure at 0.03-0.05Mpa ), concentrated to a solid content of 40% (mass percentage), dried to obtain seaweed fertilizer;

Abstract

The invention discloses a preparation method of a seaweed organic fertilizer for promoting plant growth. The method comprises the following steps of (1) removing sand from seaweed; drying the seaweed in the sun or baking the seaweed; performing crushing and ultrasonic wave wall breaking; after the wall breaking, performing ultrasonic wave extraction, filtering, concentration and drying to obtain a seaweed fertilizer; (2) taking corn stalks, purple medic, sweet potato seedlings and purslane; crushing; adding animal waste; sealing the materials; performing fermentation for 6 to 15 days, thus obtaining a plant fermentation fertilizer; (3) uniformly mixing the seaweed fertilizer and the plant fermentation fertilizer, thus obtaining the seaweed organic fertilizer. The seaweed organic fertilizer provided by the invention can effectively promote the plant growth and development, and can improve the crop and economic crop yield; practice proves that an obvious yield improvement effect can be achieved on courgette. The seaweed organic fertilizer provided by the invention has the advantages that nutrients are rich and supplement one another, so the nutrient requirement for plant growth and development can be met; the addition of chemical fertilizers is not needed; the energy is saved; the environment is protected; huge economic values and far-reaching environment significance are realized.

Description

technical field [0001] The invention relates to a preparation method of seaweed organic fertilizer for promoting plant growth. Background technique [0002] Most of the world-wide aquaculture and planting industries use chemical antibiotics, growth agents, pesticides, etc. to promote the growth of animals and plants, prevent plant epidemic diseases, etc. Although the effect is obvious, it often causes excessive agrochemical residues and environmental pollution. Adverse consequences also have a great impact on the quality of crops. In particular, excessive application of simple chemical fertilizers such as nitrogen fertilizers will intensify soil compaction and reduce soil fertility, making it difficult for the quality and nutrition of crop products to meet people's needs, let alone meet the requirements of green food, and cause serious environmental pollution. [0003] Seaweed fertilizer is a natural seaweed extract, which is harmless to humans and animals and has no pollut...
