Description

A kind of spraying agent of rice ear sprouting period

Technical field

The present invention relates to a kind of spraying agent of rice ear sprouting period, belongs to agricultural technology field.

Background technology

Heading, refers to period or state that the full grown young fringe of cereal crop stretched out from sword-like leave intrathecal.Record often with As heading standard when exposing sword-like leave sheath in the middle part of young fringe.Full field has 10% plant that beginning ear period is designated as when earing, when 50% plant ears For heading stage, it is full heading time when 80% plant ears.Heading is that cereal crop (paddy rice, wheat, corn etc.) is full grown Fringe, stretches out the phenomenon of top leaf with the elongation of stalk.It is to determine crop Cone crop how many critical period, bar to external world Part reaction is sensitive.Song puts down in hole secondary《Wind and rain has autumn scenery hastily into verselet》：" bamboo shoots unpack heap room angle, and knotweed flower is eared and wall end.” Liu Qing《History of starting an undertaking》First the 19th chapter：" Ching Ming Festival mistake, rice field highland barley and dry land wheat, all jointing.Highland barley is even Ear soon." early rice heading stage is in the first tenday period of a month in early June to July, and be now semilate rice tillering stage, late rice nursery period.In Rice heading stage, late rice was in or so mid-October in or so early September.

The characteristics of rice ear sprouting period：（1）Growth characteristic this period leaf growth stops, and grain husk is spent each portion to develop and completed, stem Stalk extends, and organic centre switchs to grain of rice growth by the Spike development of the last period.Physiological metabolism is with carbon Metabolism is dominant, and the accumulation dry of seed 2/3 is the photosynthate from Post flowering greenery.This period be determine bear fruit grains and The critical period of grain weight.The main direction of field management is to protect fringe, attacks grain, is increased weight.（2）The growing way appearance index high-yield rice later stage Appearance is to maintain a suitable leaf area index and corresponding list stem plant greenery number.Require plant greenery number in Post flowering 20 days, often Individual effective tiller remains to 3～4 greenery of holding, leaf area index 4～5.Full ripe stage, it is desirable to which Jing rice is kept for 2, long-grained nonglutinous rice requires 1～2 Complete yellow, the leaf area index 2 or so, until maturation of piece or sword-like leave and two leaves.

People to be held the time at heading stage of paddy rice, and which is reasonably managed, and is the guarantee of rice yield and quality. Paddy rice enters heading flowering period, and leaf growth stops, and clever flower development is completed, and stalk elongation is culminated, and organic centre is by previous The Spike development of section switchs to the growth of fringe grain, is the critical period for determining that bear fruit grains are how many.The emphasis measure of management is to maintain enough water Layer, prevention and elimination of disease and pests, add foliage fertilizer.

1st, enough water layers：Heading flowering period is moisture more sensitive period, grows normal field and should keep enough water layers. If leaf color has the high field of remaining green when it is due to become yellow and ripe excessive growth phenomenon or level of ground water deeply, can intermittent irrigation, take moisture management, be conducive to strengthen soil Earth permeability, improves improving activity of root system.Never cut off the water supply dry field, in order to avoid reduce setting percentage.

2nd, the preventing and treating of pest and disease damage：It is keypoint control planthopper, rice leaf roller, snout moth's larva, banded sclerotial blight, rice blast, false smut, white Leaf blight etc..It is comprehensive using agricultural and bionomic control technology, baiting technique, biological prevention and application it is selective, efficiently, Environmental protection type agricultural chemical, carries out preventing and treating up to standard.Grasp proper control time, pharmacy application amount, application process.From Buprofezin, pymetrozine Deng chemical control planthopper.Rice leaf roller is prevented and treated from Profenofos, Rynaxypyr etc..From Prochloraz, tricyclazole etc. Agent for preventing and controlling rice blast.From the chemical control snout moth's larva such as dimehypo, Cupric sulfate.In rice blast and false smut Chang Faqu and susceptible product Growing area is planted, from bacillus subtilis formulation, kasugarnycin prevention rice blast, Jing Gang-wax bud preparation, jinggangmeisu prevention rice Bent disease and banded sclerotial blight.In bacterial leaf-blight susceptible disease area, prevented and treated from 20% YE KU NING.

3rd, foliage fertilizer is added：After Rice Heading flowering, improving activity of root system declines, and functional leaf is gradually withered and yellow, easily de- fertilizer and Blade is caused to turn to be yellow too early withered, photosynthetic capacity weakens.Foliage fertilizer is suitably added in heading flowering period can prevent functional leaf Early ageing, raising setting percentage, increase mass of 1000 kernel, obtain high yield and high quality.

The content of the invention

The above-mentioned introduction to rice ear sprouting period very in detail, but deficiency, rice ear sprouting period is from fringe line from first Grain spike of rice is out bloomed to spike of rice end and goes out folder completely and successful flowering and grouting is referred to as rice ear sprouting period into paddy, may during this The experience time of 7 ~ 10 days.During Rice Heading, Rice Panicle will resist the bars such as windburn, insect pest, disease, fertility, moisture content offer Part is limited, if this period, people's management was not enough, will make the paddy rice underproduction significantly.For this purpose, a kind of Rice Heading of my invention The spraying agent of phase, can be such that paddy rice successfully tides over heading stage, and the grain of whole fringe strain can successfully be in the milk into paddy.

A kind of spraying agent solve problem of rice ear sprouting period is adopted the technical scheme that by following each material deal ratio Mix：8 parts of tricyclazole, 10 parts of triazolone missible oil, adjoin in 12 parts of worm quinoline, 15 parts of potassium dihydrogen phosphate, 12 parts of urea, brassin 3 parts of ester, 5 parts of zinc sulfate, 40 parts of water.

Tricyclazole is to prevent and treat rice blast bactericide specially, and bactericidal action mechanism mainly suppresses the melanic shape of attachment spore Into so as to suppress spore germination and attachment spore to be formed, prevention germ is invaded people and reduces the generation of magnaporthe grisea spore.Toxicity belongs to In moderate toxicity bactericide.Former powder rat acute LD50 is 305 mgs/kg, 2000 milliliters of acute percutaneous LD50 ＞/public affairs Jin, Acute inhalation LC50 0.25 milligram/m3 of ＞.There is slight stimulation to act on lagophthalmos and skin, without chronic poison under test dose Property.It is watered raw bio-safety.20%, 40%, 75% tricyclazole wettable powder of formulation, 30% suspending agent, 1%, 4% pulvis, 20% is molten Jelly.Feature has the protective fungicide of stronger absorbability.Can rapidly by each site absorption of paddy rice, the lasting period is long, drug effect Stable, consumption is low and anti-rain drop erosion.The scope of application is mainly used in the preventing and treating of rice blast.
