Problems solved by technology

However, there are still a series of problems in the product quality and manufacturing process of existing water-soluble fertilizers, such as: (1) There are many types of water-soluble fertilizers on the market, but most of them are single large, medium or trace element compounds, which are not targeted and nutritious. It is not comprehensive enough, and there is no special compound water-soluble fertilizer for citrus crops. For example, the patent of publication number CN 1314327A does not mention the addition of important elements such as Mg, Zn, and B required for citrus crops, but in the publication number: CN 102206120A In the patent, boric acid is used as the main component of B element, but boric acid has poor solubility and low effective content, which cannot effectively supplement the nutrition of citrus and improve the quality of citrus; (3) The chelation process of fertilizer metal elements needs to be carried out in a continuous high temperature environment, resulting in high production costs; (4) The waxy layer of citrus crop leaves is thick and oily, and the absorption of water-soluble fertilizers without specific additives is too poor
Limits field application of water-soluble fertilizers

Abstract

The invention discloses a compound water soluble fertilizer used for citrus crops, a preparation method and an application method. The compound water soluble fertilizer used for citrus crops is mainly used in plant nutrition field, and comprises the following components: an amino acid raw material, macroelements P and K, secondary elements Mg and Ca, trace elements Fe, Mn, Zn, B, Mo and Cu, a beneficial element Si, an auxiliary agent, a PH conditioning agent and an aqueous solution. The preparation method is characterized in that composite amino acid chelates Mn, Fe, Cu, Mg, Ca and Zn at normal temperature of 15-35 DEG C and prepares the water soluble fertilizer with six metallic elements, the reasonable fertilizing can be carried out at different growth period of the crops, the balance supplement of a plurality of nutrient elements required by citrus crops can be realized, and the output and quality of the citrus crops can be increased.

Description

Technical field: [0001] The invention belongs to a water-soluble fertilizer for fruit trees in agricultural production, and in particular relates to a special compound water-soluble fertilizer for citrus crops, a preparation method and an application technology. technical background: [0002] my country is one of the important countries of origin of citrus, with a long history of cultivation, rich citrus resources and fine varieties, and is known as the "treasure house of citrus resources in the world". Since entering the 20th century, my country's citrus has developed rapidly, and its planting area and output rank first in the world. At present, due to the single type of fertilizer and unreasonable farming system, the nutrient elements in the soil and crops are extremely unbalanced, which has seriously led to a decline in the yield and fruit quality of citrus in my country. Therefore, efficient and rational fertilization has become an important way to achieve high yield an...
