Production method of leaf fertilizer

Abstract

The invention discloses a production method of leaf fertilizer. The leaf fertilizer comprises a water repellent agent, a thickening agent, macro element fertilizer and trace element fertilizer. The leaf fertilizer is characterized in that the water repellent agent is prepared from PLGA, surfactant and PLGA solvent, the PLGA solvent is mixed with the PLGA and the surfactant according to a mass ratio of 20:1:0.1 until the PLGA is completely dissolved to obtain a PLGA dissolved solution, the water and the surfactant are mixed and stirred according to a mass ratio of 100:0.1, then the PLGA dissolved solution is added, the water ratio of the PLGA dissolved solution to the water is 10:1, the PLGA dissolved solution is rapidly stirred until form emulsion, the thickening agent is prepared from coconut oil and DMSO, a volume ratio of the coconut oil to the DMSO is 7:3, the macro element fertilizer is prepared from urea, potassium nitrate, potassium dihydrogen phosphate and magnesium sulfate ina weight ratio of 5:2:2:1. The leaf fertilizer produced by the production method of the invention is easy to absorb by plants, high in absorption rate, free from influencing the breathing and evaporation of leaves, nontoxic, harmless and good in rain resistance.

Description

technical field [0001] The invention relates to the field of foliar fertilizer, in particular to a method for preparing foliar fertilizer. Background technique [0002] Foliar fertilizer is a general term for fertilizers that provide nutrients to crops through crop leaves. It is divided into material nutrient foliar fertilizer and functional nutrient foliar fertilizer. Material nutrient foliar fertilizer is a foliar fertilizer that provides trace element fertilizers and hormones, functional nutrition Foliar fertilizer is a foliar fertilizer that provides life-origin nutrition for crops. Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and exerts basic functions through the absorption of leaves. The leaves of plants have two layers of epidermis. It is composed of epidermal cells. There are cuticles and waxes on the outside of the upper epidermal cells, which can protect the mesophyll cells under the epidermal tissue from performin...

Problems solved by technology

[0003] But although existing foliar fertilizers can increase food production, they still need to use a large amount of foliar fertilizers to achieve the desired yield increase effect, and need to spend more manpower and material resources, which makes the production cost of crops high. Foliar fertilizers are applied to After the foliage of the crops, due to the limited effect of the foliar fertilizer, it takes a long time to be absorbed by the crops and play a role, which will easily lead to low utilization efficiency of the foliar fertilizer, and the foliar fertilizer cannot resist rain
