Special seaweed foliar fertilizer for tea trees and preparation method of seaweed foliar fertilizer

Abstract

The invention relates to a special seaweed foliar fertilizer for tea trees. The special seaweed foliar fertilizer is prepared from the following ingredients in percentage by mass: 21-28% of seaweed extract, 10-15% of major element fertilizers, 5-10% of medium / trace element fertilizers, 0.5-1% of rare-earth element fertilizers, 20-45% of a chelating agent, 0.8-1.2% of a surfactant and the balance of water. The foliar fertilizer is prepared through weighing the metallic medium / trace element fertilizers and the chelating agent according to a formula ratio, respectively adding the metallic medium / trace element fertilizers and the chelating agent into water for dissolving, mixing, carrying out chelating reaction, adding the other ingredients, and uniformly stirring. The foliar fertilizer is low in cost and simple in production processing process and is safe and environmentally friendly; while the fertilizer effect is improved, the growth and development of crops can be promoted, the resistance is enhanced, the disease resistance of the crops is improved, and the quality of the crops is greatly improved.

Description

technical field [0001] The invention relates to the technical field of foliage fertilizer, in particular to a special seaweed foliage fertilizer for tea trees and a preparation method thereof. Background technique [0002] A single seaweed fertilizer is a natural organic fertilizer, and its fertilizer effect depends on the nutrients contained in the seaweed fertilizer. Since the middle of the 12th century AD, seaweed fertilizer has been widely used by people, especially in some coastal countries and regions in Europe, such as France, England, Scotland and Norway etc. In the 16th century, South Wale in the British Isles and Keswick in Germany used the rotting seaweed or seaweed ash on the shore to grow various crops and vegetables with good results. In the 17th century, the French government strongly recommended the use of seaweed as soil fertilizer in coastal areas, and clearly stipulated the conditions for collecting seaweed, harvesting time, and region. In the 1880s, some...

AI Technical Summary

Problems solved by technology

[0007] 1. Seaweed fertilizer is a natural organic fertilizer. Compared with traditional barnyard manure, the content of potassium is higher, but the content of phosphorus, nitrogen and trace elements is lower. It needs to be supplemented in an appropriate amount to make the proportion of various components in seaweed fertilizer more coordinated, so that Give full play to the superiority of seaweed fertilizer; and iron, manganese, copper, zinc, molybdenum and other trace elements are necessary in the growth process of tea leaves, the lack of any one will affect the growth of tea trees, resulting in a decline in quality

[0008] 2. The amount of chemical fertilizers applied to land in my country is generally too high, resulting in soil compaction, poor soil quality, and serious loss of nutrients contained in the soil

[0009] 3. The liquid hypertrophy using seaweed as raw material is all targeted and has a single effect, and the advantages of seaweed fertilizer cannot be fully utilized

[0010] 4. The tea tree takes its leaf buds as the commodity value, which requires the tea tree to re-germinate as soon as possible after harvesting. General fertilizers can only provide growth nutrition for it and have no ability to promote the proliferation of tea tree leaf buds.

[0011] 5. The application technology is strong, and the general users are limited to technical reasons. The use technology of liquid fertilizer is very low, that is, the rate of technology in place is low. This will not only fail to achieve the effect of fertilization, but also cause harm to crops.

Due to the excessive application of chemical fertilizers, the content of nitrite in agricultural products and drinking water has exceeded the standard, which seriously threatens the health of the people.
