Embodiment 1

[0012] 1. 2 parts of calcium nitrate, 0.5 part of zinc sulfate, 0.1 part of manganese sulfate, 0.5 part of magnesium sulfate, 0.1 part of ferrous sulfate, 0.03 part of cobalt chloride, 0.01 part of ammonium molybdate, 0.2 part of boric acid, add 100kg of mother liquor to chelate In the kettle, start the stirrer to stir evenly, the temperature is about 20-40 degrees Celsius, disperse for about 30 minutes, adjust the pH to neutral and slightly acidic, and then add 80 kg of the liquid in step 1 and phytoalcohol one by one; and maintain the reaction temperature The chelation reaction is carried out at about 50-70 degrees Celsius and slightly positive pressure for 3-5 hours, and then the pH is adjusted to neutral and slightly acidic with liquid potassium hydroxide to prepare a liquid containing various phytoalcohols and medium and trace elements fertilizer.

Embodiment 2

[0014] 2. 3 parts of calcium nitrate, 0.5 parts of zinc sulfate, 0.2 parts of manganese sulfate, 0.5 parts of magnesium sulfate, 0.2 parts of ferrous sulfate, 0.03 parts of cobalt chloride, 0.01 parts of ammonium molybdate, 0.2 parts of boric acid, add 100kg of mother liquor to chelate In the kettle, start the agitator to stir evenly, the temperature is about 20-40 degrees Celsius, disperse for about 30 minutes, adjust the pH to neutral and slightly acidic, and then add the liquid in step 1 and 200 kg of phytoalcohol one by one; and keep the reaction temperature The chelation reaction is carried out at about 50-80 degrees Celsius and slightly positive pressure for 3-5 hours, and then the pH is adjusted to neutral and slightly acidic with liquid potassium hydroxide to prepare a liquid containing various phytoalcohols and medium and trace elements fertilizer.

Embodiment 3

[0016] 3. 5 parts of calcium nitrate, 0.2 parts of zinc sulfate, 0.1 part of manganese sulfate, 0.5 parts of magnesium sulfate, 0.15 parts of ferrous sulfate, 0.03 parts of cobalt chloride, 0.01 parts of ammonium molybdate, 0.3 parts of boric acid, add 100kg of mother liquor to chelate In the kettle, start the agitator to stir evenly, the temperature is about 20-40 degrees Celsius, disperse for about 20 minutes, adjust the pH to neutral and slightly acidic, and then add the liquid in step 1 and 150 kg of phytoalcohol one by one; and maintain the reaction temperature The chelation reaction is carried out at about 50-70 degrees Celsius and slightly positive pressure for 3-5 hours, and then the pH is adjusted to neutral and slightly acidic with liquid potassium hydroxide to prepare a liquid containing various phytoalcohols and medium and trace elements fertilizer.

Abstract

The invention relates to a chelated liquid fertilizer containing multiple types of plant alcohols and medium trace elements, which is applied in the field of agriculture and forestry. The liquid fertilizer consists of the following main materials in parts by weight: 80-450 parts of soluble plant alcohols, 1-10 parts of calcium nitrate, 0.5-3.5 parts of zinc sulfate, 0.1-2.5 parts of manganese sulfate, 0.5-5 parts of magnesium sulfate, 0.1-2.5 parts of ferrous sulfate, 0.03-0.08 part of cobalt chloride, 0.01-0.05 part of ammonium molybdate and 0.2-1.0 part of boric acid. The pH value of the liquid fertilizer is adjusted to be neutral with slightly stronger acidity by adding an appropriate amount of water. The liquid fertilizer contains the multiple types of plant alcohols and has the capabilities of activating the biological activity of crops and enhancing the adsorption to the medium trace elements of the crops and the antioxidation of the crops; and the medium trace elements are capable of promoting the healthy growth of the crops and correcting the nutritional deficiency symptom of the crops. The liquid fertilizer has the characteristics of simple processing technology, low production cost, high fertilizer efficiency and the like; the liquid fertilizer is suitable to serving as a toot system and leaf top application for fruit trees, vegetables and field corps, and is particularly suitable to supplying medium trace element nutrition to the leaves or fruits during the late growth period of the fruit trees. The liquid fertilizer with multiple elements is extensive in application.

Description

technical field [0001] The invention relates to an agricultural chelating liquid fertilizer, in particular to a liquid fertilizer containing various phytoalcohols and medium and trace elements. Background technique [0002] At present, our country is in the stage where traditional agriculture and modern agriculture coexist and develop together. Traditional planting methods are gradually developing into modern agricultural equipment such as sprinkler and drip irrigation facilities, and simplified crop cultivation models. In the past, people applied base fertilizer and topdressing fertilizer to crops according to various farmyard manures, nitrogen, phosphorus fertilizers, potassium fertilizers and compound fertilizers required for the growth of field crops. In recent years, large-scale planting or planting bases have continued to rise, and modern agriculture has achieved considerable development. With the investment of agricultural mechanized equipment in agricultural producti...
