Abstract
The invention discloses a kind of Cold-resistant agent for rice, it be by the following raw material counted by weight ratio 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.Above-mentioned each raw material is after scientific compatibility, effect superposes, show through field test, spray with this product 1000 times of solution, plant irreducible water, chlorophyll can be improved, reduce the permeability of cytolemma, significantly improve the cold tolerance of rice shoot and plant, effectively prevent the harm of cold dew wind, improve setting percentage and increase thousand seed weight, paddy rice functional leaf and the aging of branch bar can also be delayed, successful resistant to lodging.
Description
Technical field
The present invention relates to Chemicals, specifically a kind of Cold-resistant agent for rice.
Background technology
The short day crop that Genus Oryza happiness temperature is good wet, heat resources is general >=place of 10 DEG C of accumulated temperature 2000 ~ 4500 DEG C be suitable for kind one season rice, the place of 4500 ~ 7000 DEG C be suitable for kinds two season rice, 5300 DEG C is the safety limit of double cropping of rice, and the triple cropping of rice can be planted in the place of more than 7000 DEG C.The area of plantation double cropping of rice, early rice, in order to rob upper season, sows the seed in spring and suitably earlier, but will run into " cold spell in later spring " weather, will cause " seedling rot "; Late rice ran into " cold dew wind " when flowering season, can cause the paddy rice underproduction or lose and receive.
At present, in order to prevent " cold spell in later spring " on the impact of rice shoot, common employing membrane covering, but time-consuming, also add 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 Cold-resistant agent for rice, the ability that the cold tolerance of early-rice seedlings and late rice resist cold dew wind after spraying this cold-resistance agent, can be significantly improved.
The technical scheme realizing the object of the invention is:
A kind of Cold-resistant agent for rice, 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 except as except osmotic adjustment in plant cytoplasm, also at stabilate macromolecular structure, reduce cellular acid, remove ammonia poison and regulate as energy sink in cell Redox gesture etc. and play an important role.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 reflects the resistance of plant to a certain extent, and the kind of strong drought resistance often accumulates more proline(Pro).Therefore measuring proline content can as the physical signs of Drought-resistant Breeding.In addition, because proline(Pro) wetting ability is extremely strong, protoplasma colloid and in-house metabolic process can be stablized, thus can reduce zero pour, have the effect preventing cell dehydration.Under cryogenic, 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-tolerance breeding;
Glycine, also can synthesizing fungicide RP-26019 and weedicide solid glyphosate for the synthesis of the intermediate glycine ethyl ester hydrochloride of pyrethroid insectide;
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 optimizes many excellent effects such as quality, resistant to lodging, disease and insect resistance, control early ageing, and have and overcome the aging receptivity of plant growth later stage root system and decline and the malnourished effect that causes;
Boric acid can be used as sterilant and catalyzer, agriculturally boracic trace element fertilizer, has fertilizer efficiency to many crops, can promote crop quality and improve output;
Zinc sulfate can be used for the disease preventing fruit tree nursery, is also a kind of conventional fertilizer of supplementary crop zinc microelement fertilizer, can makees 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 increase yield of crop.
Above-mentioned each raw material is after scientific compatibility, effect superposes, show through field test, spray with this product 1000 times of solution, plant irreducible water, chlorophyll can be improved, reduce the permeability 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, paddy rice functional leaf and the aging of branch bar can also be delayed, successful resistant to lodging.
Embodiment
Embodiment:
A kind of Cold-resistant agent for rice, 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.
With this cold-resistance agent 1000 times of solution leaching early rice seed 20-36 hour, and respectively spray once with this product 1000 times of solution in rice shoot one leaf one heart stage and two leaf one heart stages, significantly can strengthen the cold tolerance of rice shoot, prevent the effect of seedling rot clearly.Prove through field test, with this product process early rice seed and rice shoot, adult seedling rate improves 8.5-10 percentage point than open country seedling blank, improves 5-10 percentage point than mulch film seedling blank; Process rice shoot hundred strain fresh weight increases by 79.4%, hundred strain dry weights than open country seedling blank increases by 53.5%, and individual plant greenery increase by 18.5%, the wide increasing of base stem thick 7.8%, individual plant radical increases by 6.7%, and white root increases by 14%, process rice shoot hundred strain fresh weight increases by 42.1% than mulch film seedling, dry weight increases by 46.8%, the wide increasing of base stem 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, and process seedling quality is obviously better than mulch film seedling.
In addition, applicant is through adopting multiple different substances, different concns, different blended mixture to test in early rice one leaf wholeheartedly with two leaf one heart stage in field, result shows: in single dose (wallantoin, glycine, proline(Pro), chitin) test, except wallantoin can significantly improve except 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 this product 1000 times of solution, 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 total to water-soluble, can not produce flocculent precipitate, better effects if as borax.
