Problems solved by technology

Most wheat foliar fertilizers on the market use humic acid + macronutrients, and some use organic matter such as chitosan to regulate wheat growth. , there is no special wheat foliar fertilizer product
At the same time, there is no nutrient-type foliar spray patent specifically for wheat. For example, the Chinese invention patent with application number 99115747.8 belongs to a regulator-type product, which cannot effectively and timely supplement wheat nutrition.
[0004] From the perspective of the chelating mechanism of liquid fertilizers, some foliar fertilizers containing humic acid active substances use humic acid as the main chelating agent, but the chelating ability of humic acid itself is limited and its water solubility will deteriorate after chelating with trace elements , the system is suspended, the filterability is poor, and the product is prone to a large amount of precipitation, which seriously affects the appearance of the product
[0005] From the perspective of the production process of foliar fertilizer, many patents have the disadvantages of long process flow and complicated operation. For example, some foliar fertilizer patents only design one reactor, and the entire production operation is completed in one reactor. It is cumbersome and the preparation cycle is long, some even as long as 4 to 8 hours; in addition, most patents put the pH adjustment of the system at the end, which is easy to produce a large amount of flocculent hydroxide precipitation and the dissolution of this flocculent It takes a long time and a high temperature, resulting in time-consuming pH adjustment and difficult to control accurately, while wasting energy

Abstract

The present invention relates to a kind of clear liquid type composite foliage fertilizer for wheat and its production process. The composite foliage fertilizer contains macro elements, medium elements, trace elements, chelating agent, active matter, assistant, etc. It can meet the need of wheat on Ca, Mg and other medium elements, and has reasonable collocation of organic active matter and inorganic nutritious elements and optimized surfactant and its re-compound to ensure the effective absorption on nutritious elements. It is prepared with two reaction kettles, including one chelating kettle and one pre-neutralizing kettle, and through dissolving water insoluble material and most of the chelating agent in alkali solution, neutralizing, mixing and other steps.

Description

technical field [0001] The invention relates to a wheat foliar fertilizer and a production process thereof, in particular to a clear liquid type compound wheat foliar fertilizer and a production process thereof. It belongs to the field of agricultural chemistry. Background technique [0002] Foliar fertilizer is mainly to make up for the lack of soil fertilization, or to balance crop nutrition, or to relieve temporary shortage of supply during a certain growth period of crops. Distribution and the running trend of photosynthesis products, so it must be emphasized that the formula of foliar fertilizer should be scientific, and the application of foliar fertilizer should be targeted. [0003] Wheat is a very important field crop, but at present there is no ideal foliar fertilizer for wheat in China. Most wheat foliar fertilizers on the market use humic acid + macroelement type, and some use organic substances such as chitosan to regulate the growth of wheat, but it highlight...
