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

[0031] As shown in Figure 1, it is the process flow diagram of the clear liquid type compound wheat foliar fertilizer of the present invention. The production steps are as follows:

[0032] 1) Dissolve 50 kg of potassium hydroxide into a 40% solution for later use.

[0033] 2) Dilute 1.0 liter of alkylphenol polyoxyethylene ether in 30 liters of water, stir well and set aside.

[0034] 3) in pre-neutralization kettle, add 60 liters of water, add 40 kilograms of 25 mass % ammoniacal liquor, 50 kilograms of borax decahydrate and 65 kilograms of citric acid, then add step 1) prepared potassium hydroxide solution, control system temperature at 50 -80℃, stir for about 15-30 minutes, set aside.

[0035] 4) add 250 liters of water in the chelating preparation kettle, be warming up to 50-60 ℃, add 35 kilograms of citric acid under stirring condition, then add 5 kilograms of copper sulfate pentahydrate, 10 kilograms of zinc sulfate monohydrate, 150 kilograms of magnesium sulfate hept...

Embodiment 2

[0038] 1) Dissolve 30 kg of potassium hydroxide into a 35% solution for later use.

[0039] 2) Dilute 5.0 liters of alkylphenol polyoxyethylene ether and 10 liters of glycerol in 40 liters of water, and stir well for later use.

[0040] 3) add 120 liters of water in the pre-neutralization kettle, add 20 kilograms of boric acid and 40 kilograms of disodium EDTA, then add the potassium hydroxide solution prepared in step 1), and control the system temperature at 50-80 ℃, Stir for about 15-30 minutes and set aside.

[0041]4) add 200 liters of water in the chelating preparation kettle, be warming up to 60-80 ℃, add 40 kilograms of disodium EDTA under stirring condition, then add 5 kilograms of copper sulfate pentahydrate, 25 kilograms of zinc sulfate monohydrate, 100 kilograms of magnesium sulfate heptahydrate and 100 kilograms of magnesium chloride hexahydrate, and the pre-neutralization kettle solution was added at one time, then 200 kilograms of urea were added, 75 liters of ...

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...
