Abstract

The invention discloses a cold-resistant agent for rice. The cold-resistant agent is formed by mixing and uniformly stirring the following raw materials in parts by weight: 20-25 of allantoin, 10-20 of proline, 10-20 of glycine, 10-20 of potassium dihydrogen phosphate, 10-15 of boric acid, 10-15 of zinc sulfate and 5-10 of manganese sulfate. After the raw materials are scientifically combined, the effect is composited; and field trials prove that after the rice is sprayed by 1000 times of solution of the product, the bound water and the chlorophyll of plants can be improved, the permeability of cell membranes is reduced, the cold tolerance of rice seedlings and plants is obviously improved, the damage of cold dew wind is effectively avoided, the ripening rate and the thousand seed weight are improved, the ageing of functional leaves and branches of rice can be delayed, and the lodging-resistance effect is obvious.

Description

A kind of paddy rice cold-resistance agent

Technical field

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

Background technology

Paddy rice belongs to the good wet short day crop of happiness temperature, heat resources is general 〉=place of 2000～4500 ℃ of 10 ℃ of accumulated temperature be suitable for kind one season rice, 4500～7000 ℃ place is suitable for two season of kind rice, and 5300 ℃ is the safety limit of double cropping of rice, and the triple cropping of rice can be planted in the place more than 7000 ℃.The area of plantation double cropping of rice, early rice was in order to rob last 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 " during season in flowering, can cause the paddy rice underproduction or lose receipts.

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

Summary of the invention

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

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 mix, 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 the prescription: described wallantoin can improve plant colligation water-content, improves plant cold resistance power;

Proline(Pro) is one of component of plant protein, and can unbound state extensively be present in the plant materials.Under stress conditions such as arid, salt marsh, proline(Pro) accumulates in a large number in many plant materialss.The proline(Pro) of accumulation is except as the osmoregulation material in the plant cytoplasm, also at the stabilate macromolecular structure, reduce cell acidity, remove the ammonia poison and regulate aspect such as cellular oxidation reduction potential as energy sink and play an important role.Under adverse environmental factor (non-irrigated, saline and alkaline, hot, cold, freeze), the content of proline(Pro) significantly increases in the plant materials.Proline content has reflected the resistance of plant to a certain extent in the plant materials, and the kind that drought resistance is strong often accumulates more proline(Pro).Therefore measure the physical signs that proline content can be used as the drought resisting breeding.In addition, because the proline(Pro) wetting ability is extremely strong, can stablizes protoplasma colloid and in-house metabolic process, thereby can reduce zero pour, the effect that prevents cell dehydration is arranged.Under cold condition, proline(Pro) increases in the plant tissue, 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, but also synthesizing fungicide RP-26019 and weedicide solid glyphosate;

Potassium primary phosphate is novel high density phosphorus potassium two element compound manure, have 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 descends and the malnourished effect that causes;

Boric acid can be made sterilant and catalyzer usefulness, and boracic trace element fertilizer on the 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, also is a kind of fertilizer commonly used of additional 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 behind the science compatibility, the 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, effect resistant to lodging is obvious.

Embodiment

Embodiment:

Wallantoin 22

Proline(Pro) 15

Glycine 15

Potassium primary phosphate 15

Boric acid 12

Zinc sulfate 12

Manganous sulfate 8.

Soaked early rice seed 20-36 hour with 1000 times of solution of this cold-resistance agent, and each sprays once with 1000 times of solution of this product in rice shoot one heart stage of one leaf and one heart stage of two leaves, can significantly strengthen the cold tolerance of rice shoot, prevents that the effect of seedling rot is very obvious.Prove that through field test handle early rice seed and rice shoot with 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; Handling rice shoot hundred strain fresh weights increases by 79.4%, hundred strain dry weight increase by 53.5% than open country seedling blank, and the individual plant greenery increase by 18.5%, the base stem is wide to be increased slightly 7.8%, and the individual plant radical increases by 6.7%, and white root increases by 14%, handle rice shoot hundred strain fresh weights and increase by 42.1% than mulch film seedling, dry weight increases by 46.8%, and basic stem is wide to be increased slightly 0.32%, and the individual plant greenery increase by 6.9%, radical increases by 29.2%, white root increases by 33%, shows from above result, handles seedling quality and obviously is better than the mulch film seedling.
