Problems solved by technology

Due to the low solubility of phosphate, crystals are easily precipitated when the effective nutrient content exceeds 20% at normal temperature, and the properties are unstable. Therefore, the active ingredients of nitrogen, phosphorus, and potassium in existing liquid fertilizers are all lower than 20%, and the domestic market contains liquids with more than 30% active ingredients. Fertilizers are not available
For the classification of compound fertilizers, if the effective content is greater than 30%, it is called high-concentration compound fertilizer, and if it is less than 20%, it will lose the value of compound fertilizer. Because the nutrient content is too low, it will affect the use effect and is not welcomed by farmers. , Increased usage costs
On the other hand, it is generally impossible to add trace elements to liquid fertilizers, because trace elements such as zinc, boron, manganese, calcium, etc. are mixed with each other or with phosphorus to produce precipitation, which affects the properties and use effect; while using EDTA complexing agent solves the problem of adding trace elements, and because the complexing agent is expensive, it is difficult to promote in actual production

Embodiment Construction

[0023] The liquid foliar fertilizer is formulated with the following raw materials in the weight ratio: in every 1000 parts of fertilizer, 230 parts of solid ammonium polyphosphate, containing 3 crystal waters and the molecular formula is k 2 HPO 4 ·3H 2 300 parts of dipotassium hydrogen phosphate of O, 20 parts of urea, 430 parts of water, disodium octapolyborate tetrahydrate (molecular formula: Na 2 B 8 o 13 4H 2 O) 12 parts, zinc sulfate heptahydrate (molecular formula: ZnSO 4 ·7H 2 (0) 5 parts, 3 parts of plant growth regulator compound sodium nitrophenolate after adding water to mix and dilute, the ratio of compound sodium nitrophenolate and water is 1: 3.

[0024] The solid ammonium polyphosphate is produced by Caozhou Agrochemical Co., Ltd., Heze Development Zone. It adopts the existing production process and is polymerized with 85% industrial phosphoric acid and urea by heating at 170-180°C. The chain length of ammonium polyphosphate is 3<N<18, and the solid Amm...

Abstract

The invention discloses a liquid leaf fertilizer and manufacturing method, which comprises the following parts: 230g solid polyammonium phosphoric acid, 300g dipotassium hydrogen phosphate with 3 crystal water (k2HPO4 .3H2O), 20g aquacare, 430g water, 12g octal-sodium boric kernite, 5g zinc sulphate heptahydrate and 3g sodium nitride solution.

Description

Technical field: [0001] The invention relates to the field of production of liquid fertilizer for foliage spraying. Background technique: [0002] Liquid fertilizer, as a new type of high-efficiency compound fertilizer, has the following advantages: (1) There will be no dust, smoke, and less pollution during production, application, and transportation; (2) The product does not have moisture absorption and caking problems; (3) ) can be mixed with insecticides, fungicides, and herbicides and can be mixed evenly. (4) It will not segregate like solid fertilizers during storage and transportation, and the quality will be uneven; (5) There are various application methods, which can be sprayed on leaves. Water flushing can also be used for spray irrigation, drip irrigation or watering. It is convenient to use, low in cost and quick in effect; therefore, liquid fertilizer is one of the trends in industrial development in the world today. In the 1990s, the annual liquid fertilizer c...
