Abstract

The invention discloses a paddy rice cold-resistant agent which is formed by uniformly mixing and stirring the following raw materials in parts by weight: 20 to 25 parts of allantoin, 10 to 20 parts of proline, 10 to 20 parts of glycine, 10 to 20 parts of monopotassium phosphate, 10 to 15 parts of boric acid, 10 to 15 parts of zinc sulfate, and 5 to 10 parts of manganese sulfate. The compatibility of the raw materials is scientific, so as to accumulate effects; field tests show that when the paddy rice cold-resistant agent is sprayed after being dissolved in 1000 times of solution, the irreducible water and chlorophyll of a plant can be improved; the permeability of a cell membrane is reduced; the cold-resistant capability of a seedling and the plant is improved remarkably; harm of autumn low temperature can be prevented effectively; the ripening rate and thousand seed weight can be improved; the functional blades and branches of paddy rice can be prevented from aging; the lodging-resistant effect is obvious.

Description

A kind of paddy rice cold-resistance agent

Technical field

The present invention relates to Chemicals, specifically a kind of paddy rice cold-resistance agent.

Background technology

The good wet short day crop of Genus Oryza happiness temperature, heat resources is general >=place of 2000～4500 DEG C of 10 DEG C of accumulated temperature be suitable for kind one season rice, the place of 4500～7000 DEG C is suitable for two season of kind rice, and 5300 DEG C is the safety limit of double cropping of rice, and the triple cropping of rice can be planted in 7000 DEG C of above places.The area of plantation double cropping of rice, early rice was in order to rob upper season, and sowing the seed in spring will be suitably earlier, but runs into " cold spell in later spring " weather, will cause " seedling rot "; Late rice runs into " cold dew wind " in the time of flowering season, can cause the paddy rice underproduction or lose and receive.

At present, in order to prevent " cold spell in later spring " impact on rice shoot, common employing membrane covering, but time-consuming, also increase production cost.Anti-" cold dew wind " can only adopt some indigenous methods, or lets matters drift.

Summary of the invention

The object of the invention is to provide a kind of paddy rice cold-resistance agent, spray the ability that can significantly improve the cold tolerance of rice sprouts early and late rice after this cold-resistance agent and resist cold dew wind.

The technical scheme that realizes the object of the invention is:

A kind of paddy rice cold-resistance agent, it be by following raw material by weight through mixing, stirring forms:

Wallantoin 20-25

Proline(Pro) 10-20

Glycine 10-20

Potassium primary phosphate 10-20

Boric acid 10-15

Zinc sulfate 10-15

Manganous sulfate 5-10.

Products obtained therefrom is white pulvis, and working concentration is 950-1200 times of liquid.

In formula: described wallantoin can improve plant colligation water-content, improve plant cold resistance power;

Proline(Pro) is one of component of plant protein, and can unbound state extensively be present in plant materials.Under the stress conditions such as arid, salt marsh, in many plant materialss, proline(Pro) accumulates in a large number.The proline(Pro) of accumulation is except as osmotic adjustment in plant cytoplasm, also at stabilate macromolecular structure, reduce cell acidity, remove ammonia poison and regulate the aspects such as cellular oxidation reduction potential to play an important role as energy sink.Under adverse environmental factor (non-irrigated, saline and alkaline, hot, cold, freeze), in plant materials, the content of proline(Pro) significantly increases.In plant materials, proline content has reflected the resistance of plant to a certain extent, and the kind of strong drought resistance often accumulates more proline(Pro).Therefore measure the physical signs that proline content can be used as Drought-resistant Breeding.In addition, because proline(Pro) wetting ability is extremely strong, can stablize protoplasma colloid and in-house metabolic process, thereby can reduce zero pour, have the effect that prevents cell dehydration.Under cold condition, in plant tissue, proline(Pro) increases, and can improve the winter resistance of plant, therefore, also can be used as the physical signs of cold-resistant breeding;

Glycine is for the synthesis of the intermediate glycine ethyl ester hydrochloride of pyrethroid insectide, also can synthesizing fungicide RP-26019 and weedicide solid glyphosate;

Potassium primary phosphate is novel high density phosphorus potassium Was Used compound manure, there is remarkable increasing both production and income, the amount of changing and optimize many good effects such as quality, resistant to lodging, disease and insect resistance, control early ageing, and have and overcome that the aging receptivity of plant growth later stage root system declines and the malnourished effect that causes;

Boric acid can be used as sterilant and catalyzer, and boracic trace element fertilizer in agricultural, has fertilizer efficiency to many crops, can promote crop quality and improve output;

Zinc sulfate can be used for preventing the disease in fruit tree nursery, is also a kind of conventional fertilizer of supplementary crop zinc microelement fertilizer, can make base manure, foliage fertilizer etc.;

Manganous sulfate can be used as base manure, soaks seed, dresses seed, topdresses and the sprinkling on blade face, can promote the growth of crop to increase output.

Above-mentioned each raw material is after science compatibility, effect stack, show through field test, spray with 1000 times of solution of this product, can improve plant irreducible water, chlorophyll, reduce the saturating property of cytolemma, significantly improve the cold tolerance of plant, effectively prevent the harm of cold dew wind, improve setting percentage and increase thousand seed weight, can also delay paddy rice functional leaf and the aging of branch bar, successful resistant to lodging.

Embodiment

Embodiment:

A kind of paddy rice cold-resistance agent, it be by following raw material by weight through mixing, stirring forms:

Wallantoin 22

Proline(Pro) 15

Glycine 15

Potassium primary phosphate 15

Boric acid 12

Zinc sulfate 12

Manganous sulfate 8.

Soak early rice seed 20-36 hour with 1000 times of solution of this cold-resistance agent, and respectively spray once with 1000 times of solution of this product in one one heart stage of leaf of rice shoot and two one heart stages of leaf, can significantly strengthen the cold tolerance of rice shoot, prevent that the effect of seedling rot is very obvious.Prove through field test, process early rice seed and rice shoot by this product, adult seedling rate improves 8.5-10 percentage point than open country seedling blank, improves 5-10 percentage point than mulch film seedling blank; Processing rice shoot hundred strain fresh weights increases by 79.4%, hundred strain dry weight increase by 53.5% than open country seedling blank, and individual plant greenery increase by 18.5%, the wide increasing of base stem is thick 7.8%, and individual plant radical increases by 6.7%, and white root increases by 14%, process rice shoot hundred strain fresh weights and increase by 42.1% than mulch film seedling, dry weight increases by 46.8%, and the wide increasing of base stem is thick 0.32%, and individual plant greenery increase by 6.9%, radical increases by 29.2%, white root increases by 33%, shows from above result, processes seedling quality and is obviously better than mulch film seedling.

In addition, applicant is through adopting multiple different substances, different concns, different blended mixture to test in one wholeheartedly with two one heart stages of leaf of leaf of early rice in field, result shows: in single dose (wallantoin, glycine, proline(Pro), chitin) test, except wallantoin can significantly improve the cold tolerance of rice shoot, although glycine, proline(Pro), chitin also can improve the cold tolerance of paddy rice, its cold-resistant effect with contrast no significant difference.And spray with 1000 times of solution of this product, cold-resistant effect is best, even if reduce working concentration, also can show significant cold-resistant effect.

Applicant also finds in test, when boric acid and potassium primary phosphate are common water-soluble, can as borax, not produce flocculent precipitate, better effects if.
