Problems solved by technology

However, the protective effect of commercially available seed coating agents is mainly to protect seeds from pests and diseases, and lacks drought resistance, cold resistance, salt and alkali resistance, etc.
For example, when cotton coated seeds suddenly encounter low temperature and freezing weather such as cold spring, they are prone to full seedling emergence, weak seedling emergence or even rotten seeds, rotten roots and no seedlings, etc., which is not conducive to the normal growth and development of cotton
In addition, the germination rate of the coated seeds is low. Cotton coated seeds that are directly broadcast in the open field under normal climatic conditions usually need to place 3 to 4 seeds in each hole to grow 1 to 2 seedlings, and the effective utilization rate of the seeds is low.
At present, the commercially available seed coating agents suitable for cotton and peanuts (such as Shileshi, Gaoqiao, Weifu, etc.) focus on insect or disease resistance, and their functions are relatively single, lacking drought resistance, cold resistance, salt-alkali resistance, Practical functions such as growth promotion
And a small number of seed coating agents with special functions are mostly added with artificial synthetic plant hormones (such as naphthalene acetic acid, brassinolide, metriamine, etc.), and artificial synthetic hormones are difficult to be decomposed by plants (there is a lack of corresponding decomposing enzymes in plants) ), remain in the soil and plants for a long time, and have potential adverse effects on the soil environment and human health. With the wide application of this kind of seed coating agent, its residue problem has attracted great attention

Embodiment 1

[0030] In this example, the functional additives for crops are composed of the following components in mass percentage: 0.4% triacontanol, 2% sodium lauryl sulfate, Tween-204%, 15% biochemical fulvic acid, γ- Polyglutamic acid 3%, the balance is water.

[0031] The preparation method of functional additives for crops, the steps are as follows: add triacontanol crystals and sodium lauryl sulfate into water (50%), heat while stirring, wait until the temperature rises to 75 ° C, at 2500 rpm Stir and emulsify for 25 minutes until the triacontanol crystals are completely dissolved, add Tween-20 and continue to stir until the solution is clear, and cool naturally to room temperature to obtain a triacontanol emulsion; add biochemical fulvic acid to the remaining water, stir and disperse until completely Dissolve, then add γ-polyglutamic acid while stirring, mix evenly, add triacontanol emulsion, and mix well.

Embodiment 2

[0033] The functional adjuvant for crops in this example is composed of the following components in mass percentage: 0.1% triacontanol, 2.5% polyaspartic acid, 2% sodium lauryl sulfate, Tween-804%, mixed Amino acid 20%, polyanionic cellulose 1%, and the balance is water.

[0034] The preparation method of the functional adjuvant for crops comprises the following steps: first dissolving sodium lauryl sulfate in water (30%), then adding triacontanol crystals to sodium lauryl sulfate preheated to 80°C In the solution, stir and disperse until the triacontanol crystals are completely dissolved, then add preheated Tween-80 and water (50%) under constant temperature conditions, stir and mix and then cool rapidly to obtain a triacontanol emulsion; in the remaining Add polyaspartic acid and mixed amino acids to water, stir and disperse until completely dissolved, then add polyanionic cellulose while stirring, mix well, add triacontanol emulsion, and mix well to get ready.

Embodiment 3

[0036] The functional additives for crops in this example consist of the following components in mass percentage: 0.3% triacontanol, 2% polyaspartic acid, 2% sodium lauryl sulfate, 6% tea saponin, natural Fulvic acid 10%, mixed amino acid 10%, polyanionic cellulose 1.2%, and the balance is water.

[0037] The preparation method of the functional auxiliary agent for crops, the steps are as follows: first sodium lauryl sulfate and tea saponin are dissolved in water (30%) to prepare sodium lauryl sulfate solution and tea saponin solution, and then Add the triacontanol crystals into the sodium lauryl sulfate solution preheated to 80°C, stir and disperse until the triacontanol crystals are completely dissolved, then add the preheated tea saponin aqueous solution under constant temperature conditions, stir and mix evenly and quickly Cool to obtain triacontanol emulsion; add polyaspartic acid, natural fulvic acid and mixed amino acids to the remaining water, stir and disperse until c...

Abstract

The invention discloses a functional auxiliary agent for crops and a preparation method thereof, and belongs to the technical field of auxiliary agents / additives for agricultural production. The functional auxiliary agent for the crops is composed of a plant growth regulator, an emulsifier, a water soluble organic matter and a water-retaining agent, has the advantages of good water solubility and permeability, stable drug effect, safety and no toxicity, and can be cooperatively used with a seed coating agent (for seed soaking or seed blending); while original insect-resistant and disease-resistant activities of the seed coating agent are maintained, the functional auxiliary agent improves the germination rate and the seedling emergency rate of coated seeds in a way of direct seeding on an open field, increases the adaptability and resistance ability of the seed seedlings to adverse environments (such as drought, low temperatures and saline and alkaline conditions), makes the seeds efficiently used, and reaches the effects of protecting and caring the seedlings. The functional auxiliary agent can be used alone as a nutritional agent or a nutritional additive, and has the effects of promoting growth and increasing the yield.

Description

technical field [0001] The invention relates to a functional adjuvant for crops and a preparation method of the functional adjuvant, belonging to the technical field of adjuvants / additives for agricultural production. Background technique [0002] Cotton and peanut diseases and insect pests commonly occur in cotton-producing countries and peanut planting areas in the world. The more common diseases are seed-borne and soil-borne diseases, such as Fusarium wilt, Verticillium dahliae, R. blight, and anthracnose against cotton. Pests Species include aphids, cotton spider mites, cotton bollworms, red spiders, mirid bugs, grubs, mole crickets, etc. With the development of large-scale centralized planting of cotton and peanuts, the occurrence of diseases and insect pests has become more frequent and serious, and has become the main factor affecting the yield and quality of cotton and peanuts. Compared with other pest control measures, it is the most economical and simple method to...
