Problems solved by technology

[0004] During the application process of spraying water-soluble fertilizers with trace elements, since the leaf surface of many plants is often covered with a hydrophobic waxy layer, and the hydrophobic waxy layer has a certain surface tension, it is not easy to be wetted by water-soluble fertilizers, thus The utilization rate of water-soluble fertilizers is reduced, resulting in a waste of resources. The main method to reduce the surface tension of water-soluble fertilizers is to add surfactants to them. However, conventional surfactants cannot be biodegraded or are toxic, which is not conducive to the construction of green ecological agriculture.

Abstract

The invention relates to a preparation method of a trace element water-soluble fertilizer capable of enhancing wetting performance. The method comprises the following steps: taking a humic acid reagent, EM bacteria, water-soluble starch, rice bran, wheat bran and water, fermenting the materials for 15-20 days in a sealing mode at the temperature of 45-65 DEG C, uniformly stirring the materials every three days, and performing constant-temperature drying at the temperature of 75 DEG C to obtain the modified humic acid reagent; taking water and heating water to the temperature of 30-40 DEG C, adding a chelating agent and an anti-oxidant, then adding trace elements, using boric acid and borax to adjust the pH value of a solution to 4.0-5.5, adding the modified humic acid reagent and a silicone surfactant, adding an antifoaming agent and the anti-oxidant, then adding iron sulfate heptahydrate, supplying water, stirring the materials while adding the materials, and after stirring, filteringinsoluble substances to obtain the trace element water-soluble fertilizer capable of enhancing wetting performance. The trace element water-soluble fertilizer capable of enhancing wetting performancehas good moistening performance on plants leaves, and has the advantages of high utilization rate, antioxidation, simple preparation method, low cost, and easy operation.

Description

technical field [0001] The invention relates to the technical field of water-soluble fertilizers, in particular to a trace element water-soluble fertilizer with enhanced wetting performance and a preparation method thereof. Background technique [0002] my country is one of the countries with poor freshwater resources in the world. The seasonality of agriculture, uneven distribution of industries, and regional water shortages are prominent. As a new type of environmentally friendly fertilizer, water-soluble fertilizers are easy to use, can be sprayed, flushed, and can be used in combination with drip irrigation, which has obvious advantages in improving fertilizer utilization, saving agricultural water, reducing ecological environmental pollution, improving crop quality, and reducing labor. With the intensive and large-scale development of China's agriculture, the further shortage of water resources, and the continuous emergence of large-scale farms, the agricultural area of...
