preparation example Construction

[0058] The present invention also provides a preparation method of the above-mentioned anti-lodging fertilizer for dry farming of rice, comprising: S1) dissolving sugar alcohol in water, and then adding aminobutyric acid and alginic acid to obtain solution A; adding β-1,3-glucose Polyoligosaccharides were dissolved in water, and then methyl salicylate and sulfamethazine were added to obtain solution B; S2) the solution A was mixed with solution B, then lignosulfonate was added, and water was added to make up to 1000 parts by weight to obtain the anti-lodging fertilizer for rice dry farming.

[0059] Wherein, the sugar alcohols, aminobutyric acid, alginic acid, β-1,3-glucan oligosaccharides, methyl salicylate, sulfamethazine and lignosulfonate are all the same as above, and will not be repeated here. repeat.

[0060] Dissolve the sugar alcohol in water, preferably slowly add the sugar alcohol into the water until completely dissolved, stir evenly, then add GABA and alginic aci...

Embodiment 1

[0069] Raw materials of anti-lodging fertilizer for rice dry farming are:

[0070]

[0071]

[0072] Composite EDTA chelated iron, manganese, copper, zinc, calcium 25kg (single component is 5kg);

[0073] Tween (80) 5kg;

[0074] Water Adjust final total volume to 1000L.

[0075] According to the above formula, slowly add the four sugar alcohols into water until they are completely dissolved, stir well, then add aminobutyric acid, stir well; then add alginic acid, potassium dihydrogen phosphate, EDTA chelated trace elements in turn, stir well, heat Stir at a constant speed until all materials are completely dissolved at 80°C; after cooling, add citric acid to adjust the pH to 6.5 to obtain solution A.

[0076] Add β-1,3-glucan oligosaccharide into water, stir evenly, then add 1% methyl salicylate solution and sulfamethazine in turn, stir evenly, add citric acid, stir at a constant speed, adjust the pH value to 6.5, Solution B is obtained.

[0077] Mix solution A and ...

Abstract

The invention provides rice dry farming lodging-resistant fertilizer. The lodging-resistant fertilizer comprises the following components in parts by weight: 10 to 350 parts of aminobutyric acid, 15 to 100 parts by weight of alginic acid, 80 to 200 parts by weight of sugar alcohol, 0.1 to 0.2 part by weight of methyl salicylate, 0.1 to 10 parts by weight of sulfadimidine, 5 to 10 parts by weight of lignosulfonate, and 0.1 to 20 parts by weight of beta-1, 3-glucan oligosaccharide, and supplementing water to 1000 parts by weight of the rice dry farming lodging-resistant fertilizer. Compared withthe prior art, the fertilizer provided by the invention acts on leaves of the dry rice, can be quickly absorbed by the dry rice, can be quickly transported in crop conduits and sieve tubes, and can be quickly transferred to specific organs required by growth and development of the dry rice, according to the invention, the requirements of rice on phosphorus and potassium nutrients can be fully met, root system pricking of dry rice can be promoted, pore opening and closing can be adjusted, transpiration can be reduced, and the strength and flexibility of rice stems, stalks and leaves can be enhanced, so that water saving can be realized, and the lodging resistance of rice can be improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizer processing, and in particular relates to a rice dry farming anti-lodging fertilizer and a preparation method thereof. Background technique [0002] Rice is one of the important ration crops in my country, and its stable and high yield is very important to ensure the food security of our country. With the rapid development of social economy, a large number of high-quality rural laborers are transferred to cities and towns, and the mechanized and simplified rice planting methods are favored by farmers. Rice dry farming has gradually been popularized for its advantages of saving fresh water resources, rationally utilizing land resources, facilitating mechanized production, reducing labor intensity, and reducing weight and drugs, which is conducive to green production. [0003] Actively respond to the call of the state, and implement the concept of "saving water and benefiting mankind, benefiting ...
