Problems solved by technology

The symptoms of manganese deficiency in crops are that the tissues between the veins of young leaves gradually turn yellow, and yellow-green stripes parallel to the veins appear along the veins from the tip to the base, the leaves are soft and drooping, the stems are thin and weak, the grains are not full and arranged unevenly, and the roots are thin and long , leading to poor lodging resistance and reduced yield

Embodiment 1

[0030] Example 1 Preparation of superabsorbent resin

[0031] A superabsorbent resin for manganese-rich slow-release compound fertilizer, the preparation method of which is:

[0032] Polyethylene glycol dimethacrylate is dissolved in water, the amount of water used for 1.2g polyethylene glycol dimethacrylate is 20.0ml, ammonium persulfate is dissolved in water, and the amount of water used for every 0.4g ammonium persulfate is 12.0ml, put 30g acrylic acid monomer and 20g 2-acrylamido-2-methylpropanesulfonic acid monomer into the reactor, add the previously prepared polyethylene glycol dimethacrylate aqueous solution and ammonium persulfate aqueous solution Also added to the reactor, heated to 70°C in a water bath for 6 hours to generate a transparent elastic substance, the transparent elastic substance was taken out from the reactor, cut into pieces, dried at 70°C for 7 hours, and stored after cooling. Can.

Embodiment 2

[0034] A manganese-rich slow-release compound fertilizer, made from the following raw materials in parts by weight: 31 parts of brown manganese ore, 27 parts of manganese ore, 21 parts of pyrolusite, 15 parts of manganese chloride, 12 parts of manganese sulfate, 54 parts of calcium nitrate, phosphoric acid 41 parts of potassium dihydrogen, 6 parts of white bark, 7 parts of masson pine bark, 3 parts of drunken michelia leaves, 5 parts of acacia leaves, 26 parts of rape straw, 20 parts of manure, 2 parts of brown sugar powder, 7 parts of banana peel part, 0.6 part of composite microorganism and 2 parts of superabsorbent resin prepared in Example 1. Wherein, the composite microorganisms are composed of microorganisms in the following weight ratios: Streptomyces costa Rica: Paecilomyces lilacinus: Stemoborbium azurite = 3:6:5, and the microorganisms have been activated and are directly used for fermentation.

Abstract

The invention discloses a manganese-rich slow-release compound fertilizer, characterized by being made from, by weight, 31-33 parts of braunite, 27-29 parts of manganite, 21-23 parts of pyrolusite, 15-17 parts of manganese chloride, 12-14 parts of manganese sulfate, 54-56 parts of calcium nitrate, 41-43 parts of monopotassium phosphate, 6-8 parts of Picea meyeri bark, 7-9 parts of Pinus massoniana bark, 3-5 parts of Michelia macclurei leaf, 5-7 parts of Acacia mangium leaf, 26-28 parts of rape straws, 20-22 parts of stable manure, 2-4 parts of brown powdered sugar, 7-9 parts of banana peel, 0.6-0.7 part of a microorganism complex, and 1-3 parts of high-absorbent resin. As the high-absorbent resin may form 'island structure' after absorbing water, necessary nutrients can be provided slowly for a long time for crops to grow, manganese necessary to the growth of crops is particularly provided, and manganese deficiency in crops is avoided effectively.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a manganese-rich slow-release compound fertilizer. Background technique [0002] In modern agricultural production, we can see compound fertilizers everywhere. It has the advantages of high nutrient content, less auxiliary components, high fertilizer utilization rate, and convenient storage and application. It plays an important role in promoting high and stable crop yields. Slow-release compound fertilizer is an important category of compound fertilizers, and it is also the focus of research on the development of my country's chemical fertilizer industry. Its slow-release principle is to coat a thin layer of hydrophobic substances on the surface of fertilizer particles, so that the internal nutrients are slowly released to the In the soil, nutrients are continuously supplied to crops, which effectively improves the utilization rate of fertilizers. However, the existing slo...
