[0002] Liquid fertilizer is a new type of high-efficiency compound fertilizer. Compared with solid fertilizer, liquid fertilizer has the advantages of fast fertilizer effect, no caking, diverse usage methods, and less pollution during production, transportation and use.

[0003] However, there are still some irrational factors in the use of liquid fertilizers in current crop production. Excessive pursuit of nitrogen, phosphorus and potassium required by crops, as well as unreasonable and improper fertilization methods have led to low fertilizer utilization rate, resulting in nutritional imbalance and quality decline of crops, as well as deterioration of cultivated soil properties and serious environmental pollution. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to provide a liquid fertilizer.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Preferably, the liquid fertilizer is composed of the following components in parts by weight: 385 parts of monoammonium phosphate, 330 parts of urea, 130 parts of potassium chloride, 5 parts of a rooting agent, 50 parts of polyglutamic acid, 5 parts of mineral potassium humate, 5 parts of a dispersant, 10 parts of a suspending agent, and 80 parts of deionized water.

[0008] Preferably, the production process of the liquid fertilizer comprises the following steps:

[0009] S1, start the grinder and add deionized water into the grinder;

[0010] S2, sequentially add urea, monoammonium phosphate, potassium chloride, mineral potassium humate, dispersant, rooting agent, and polyglutamic acid into the grinder;

[0011] S3. After grinding for 3 hours, the preparation is in a uniform state and can be released.

[0012] Preferably, the method for using the liquid fertilizer comprises the following steps:

[0013] S1. Foliar spraying: 800-1000kg in the seedling stage, 500-800kg in other growth and development stages. The spraying amount should be such that there is no water dripping on the leaves. Spray once every 7-10 days.

[0014] Preferably, the method for using the liquid fertilizer comprises the following steps:

[0015] S1. Drip irrigation: 5-10kg per mu each time during the seedling stage; 10-20kg per mu each time during the fruit swelling stage.

[0016] Preferably, the method for using the liquid fertilizer comprises the following steps:

[0017] S1. Furrow application: 10-20kg per mu each time.

[0018] The present invention has the following beneficial effects:

[0019] 1. This liquid fertilizer is a high-phosphorus macro-element suspended water-soluble fertilizer. It is a highly concentrated supersaturated solution with ultra-fine particle size, better water solubility, can be quickly absorbed by crops, has quick effect and high utilization rate.

[0020] 2. Balance the nutrition among the roots, stems and leaves of crops, promote the differentiation of flower buds, improve the stress resistance of crops, promote the growth of green leaves and make the grains plump.

[0021] 3. Specially added natural biostimulants have the functions of continuous rooting and improving fertilizer utilization rate. They are friendly to the soil environment and leave no residue.

[0022] 4. Every drop of fertilizer has the same nutrients, which helps solve the problem of uneven nutrient absorption by plants. DETAILED DESCRIPTION
