Description

Rice field Propineb combination herbicide is mixed to apply plant protection method

Technical field

The present invention relates to agricultural plantation technology fields, apply more specifically, it relates to which rice field Propineb combination herbicide is mixed Plant protection method.

Background technique

Since the eighties, paddy field weeding mentions seedling and tillering fertilizer application continues up the traditional habit of " two steps are walked ", i.e., and first Step: weeding, step 2: fertilising.This weeding, fertilising " two steps are walked " though method is used till today always, and limitation is inevitable, Increasingly show.

First is that being easy to produce phytotoxicity.Herbicides for use in paddy is very high using technical requirements, careless slightly in use process, easily produces Raw herbicide damage, not only herbicidal effect cannot be guaranteed, and can also hurt innocent persons rice shoot, cause Huang Miao, distortion, root decline, runt seedling, Dead seedling, or even full field plant are withered and dead.

Second is that eliminating phytotoxicity wants secondary investment.It eliminates or delays as early as possible it is necessary to take feasible measures in time once phytotoxicity generates Solve the sprawling of phytotoxicity.Various plants growth regulator or the multiple method of foliar fertilizer alternating spray are generallyd use, is subtracted with alleviating as early as possible Light rice shoot phytotoxicity, makes it be gradually recovered growth.

Third is that safety interlocking hidden danger.To the phytotoxicity that herbicide generates, if remedying not in time or improper measures, phytotoxicity will no To timely alleviation and eliminate, it is serious to there is also crushing injury.So, mending cultivation (seedling) or reseeding (reseeding) is exactly only One outlet.Since Miao Yuan cannot be ensured in time, mending to plant can face available without of the right age seedling, and reseeding the seeding stage will significantly postpone, Cause breeding time inconsistent, cannot the same period it is mature, directly affect the full Ji Shengchang of rice.

Fourth is that delay mentions seedling.The process for mentioning seedling is exactly to promote rice shoot thribble, slow seedling, strong sprout, prevent runt seedling, takes root more, grows Bai Gen promotes early stage low section tiller.Traditional measure, which generally uses, spreads fertilizer over the fields the method that urea mentions seedling, 7-10 days after shoot transplanting equipment Spread fertilizer over the fields tillering fertilizer.

Fifth is that time-consuming expensive.Traditional farming operations of weeding, fertilising " two steps are walked " are not only postponed 10 days or so and being mentioned The seedling time, it is also necessary to which investment is artificial twice (first weeding, rear to apply fertilizer).It manually goes to eliminate if generate phytotoxicity and also to put into third time Phytotoxicity.Prime time breeding time and multi-pass operation time are not only wasted, multiple input cost is also increased.

Summary of the invention

It is gloomy in view of the deficiencies of the prior art, the present invention intends to provide a kind of rice field third to solve the above problems Zinc combination herbicide is mixed to apply plant protection method, and once-through operation reaches the unification of " weeding, pest controlling mention seedling, diseases prevention " quadruple effect, breaks repeatedly The traditional mode of production mode of operation, in advance tiller of turning green in 10 days or so ensure full stand strong sprout after rice transplanting, and the same period is mature, high yield Good harvest.

To achieve the above object, the present invention provides the following technical scheme that

Rice field Propineb combination herbicide is mixed to apply plant protection method, presses 80-100 grams of Propineb dosage mixed herbicide routine agent per acre The disposable operation of amount applies in rice field.

70% Wettable propineb powder is a kind of wide spectrum fast-acting type protectiveness low toxicity fungicide, and functional period is long, it is necessary in disease Before evil occurs or phase spray is originated, to crop safety under recommended dose.Physicochemical property: density 0.28, pH5.2, it is suspending stabilized Property be greater than 75%, MEBO ribbon gauze was less than 120 seconds, and water content is less than 2.5%, storage at normal temperature stability 2 years or more.It can not be with copper agent It is mixed with basic agent.

Propineb sterilizing mechanisms: the oxidation of pyruvic acid mainly in inhibition pathogenic bacteria inhibits infecting and sprouting for spore, It can inhibit mycelial growth simultaneously, lead to its deformation, death.

The mixed feasibility for applying Propineb of herbicide:

Herbicides for use in paddy, 70% Wettable propineb powder belong to faintly acid, and the two can be used in mixed way completely, will not generate Acid-base neutralization reaction will not generate the antagonism for the respective effect that influences each other, the performance for the respective drug effect that is independent of each other.

The mixed necessity for applying Propineb of herbicide:

(1) root system all especially can be non-nursery by a degree of injury during rice shoot is from seedbed lifting to field-transplanting The dry rice seedling of disk nursery or the rice shoot in watery ricenursery seedbed.A large amount of root systems fracture a large amount of wounds that will cause for pathogen infection, It needs to heal in time, because there are ten hundreds of pathogen to infect rice shoot root system wound at any time in field soil, if root system is hurt Mouth heal not in time to after transplanting rice shoot thribble, turn green, long new root will exert a decisive influence, what is generally occurred is exactly to transplant Rice shoot root decline, Huang Miao, dead seedling afterwards, for a long time not root of hair (runt seedling is not sent out).70% Propineb, which can play, inhibits Mycophyta pathogen The sterilization mechanism of mycelial growth ensures that injured root system wound is not healed in time by the infringement from various pathogen, And as early as possible thribble, tiller, turn green, tiller.Give full play to the effect of its protective fungicide.

(2) status of zinc during rice growth: zinc participates in the intracorporal oxidation-reduction process of plant, can promote Yin The synthesis of indolylbutyric acid, that is, auxin；The activity of the carbonic anhydrase of activated plant body, the carbonic acid facilitated in chloroplaset accelerate conversion, Accelerate photosynthesis；The molecule for reinforcing messenger ribonucleic acid is stablized, to influence protein synthesis.Yangtze river basin rice producing region The harm of rice zinc-deficiency is gradually aggravating.Rice belongs to the field crop sensitive to zinc-deficiency.Symptoms are auxin reduction, are caused Little leaf and foliage disease, Chlorophyll synthesis are obstructed, and lead to yellow leaf.Symptom caused by rice zinc-deficiency claims " red seedling diseases ", " burns Seedling ".There is chlorosis striped along master pulse in plant lower blade, atrophy not tiller brown rust shape spot occurs on blade, rounded Or oval, when serious, leaf middle arteries bleach color.The blade base chlorosis newly extracted out is faded, then whole chlorosis.Rice strain top Suppressed, there is brown spot in middle part blade, gradually forms brown striped, and the downward browning of blade tip is shrivelled, so that in agricultural production Rice zinc supplementation is very urgent.Zn-ef ficiency in Propineb, can effectively meet this season rice zinc-deficiency demand, eliminate zinc-deficiency to rice not With the adverse effect of breeding time；Promote rice plant healthy growth simultaneously, prevention early ageing improves yield, promotes photosynthesis, promotees It is formed into callus, drought resisting, disease resistance is improved, so that the effect of Propineb protective fungicide greatly improves.

(3) rice yield is improved, not only to be worked hard on " promoting tiller ", is critical to promoting rice " early tiller " function up and down Husband.So tillering fertilizer suitably must be chased after early, it is ensured that early hair is fast long.Dressing time should be grown in rice shoot root regeneration, plant turns green (after transplanting 7--10 days) carry out afterwards, and only early apply just is conducive to the tiller of rice morning, more tillers in due course, tillering node are reduced, to strive fringe It is long, strive grain and create conditions again.Fetilizer for tillering is subdivided into dressing of turnning green stage and tillering fertilizer, the mostly common urea of tillering fertilizer.But urea is as tillering fertilizer Using there is obvious shortcoming, after the rigid rice transplanting of rice, root system is not flourishing enough, and base manure can't play a role very well, and urea, which is used as, to be divided Fetilizer for tillering is affected by fertilizer nature and temperature, can just be had an effect within 7 days or so, due to giving birth to temperature early period, water temperature, soil Temperature is all lower, and nutrients release is slow, and Propineb quickly zinc supplementation can promote the early tiller of tiller rush.It is applied not with Propineb and herbicide are mixed at this time It is only capable of filling up the notch that shoot transplanting equipment initial stage base manure cannot play a role in time, moreover it is possible to overcome urea because temperature early period is low, nutrient The slow deficiency of release action, zinc supplementation synergy can also suitably reduce the amount of imposing of urea.In addition, timely weeding energy after rice transplanting It effectively prevent weeds in field and rice shoot to fight for nutrient, it is particularly significant to promotion tiller rice early period.

(4) herbicide damage takes place frequently phenomenon suddenly such as tiger, and herbicides for use in paddy market confusion, kind is many and diverse, uses technical requirements Height, phytotoxicity phenomenon generally occur.The organic Zn content of 70% Propineb is 15.8%, 8 times higher than Mancozeb class fungicide zinc content, Its organic zinc provided is easily absorbed and is utilized by rice leaf, and Zn-ef ficiency penetrates into the efficiency of plant than inorganic zinc (such as sulfuric acid Zinc etc.) 10 times high, efficient zinc supplementation, promoting root growth strong sprout, well developed root system, tiller is fast, blade is thick green, effectively the gentle solution herbicide medicine of control The harm of harmful and poor environment factor bring.

(5) Propineb wide sterilization spectrum, a medicine are anti-mostly sick.70% Propineb is to rice sheath blight disease, rice blast, false smut, Hu A variety of fungus diseases such as numb pinta have a good preventive effect, the ultra micro fineness of wettable powder, make it is wet rapidly, Suspensibility is high, adherence is strong, resistance of rainwater washing against.It is lasting medicine, stabilization, safe and harmless.

The present invention is further improved technical solution, is suitable for the artificial transplant field application of seedlings or machine transplanting of rice rice seedling bed, rice transplanting Field application.

The further improved technology scheme of the present invention is that " secondary to close down " technology is taken in machine transplanting of rice rice seedling bed, seedling throwing field application, or " eliminating for zero day " technology, or " even envelope band kills " technology.

The further improved technology scheme of the present invention is the artificial transplant field application of seedlings, the work in 5-7 days after rice transplanting Afterwards, it by herbicide routine dose is combined with 80-100 grams of 70% Wettable propineb powder per acre, mixes damp fine earth and spreads fertilizer over the fields, after application Field is retained 5-7 days.

The further improved technology scheme of the present invention is that " secondary to close down " technology is taken in machine transplanting of rice rice seedling bed, seedling throwing field application, I.e. for the first time when taking advantage of muddy water muddiness after Shang Shui rakes field, is combined remove with 80-100 grams of 70% Wettable propineb powder per acre Careless agent routine dose, which is sprayed or got rid of, to be applied, and field will have 3-5 centimetres of water layer when application, is transplanted after soil sinks reality after application； For the second time after shoot transplanting equipment work in 5-7 days, the agent of herbicide routine is combined with 80-100 grams of 70% Wettable propineb powder per acre Amount, mixes fine earth or fertilizer is uniformly spread fertilizer over the fields, and field will have water layer when application, and is kept for shoaling layer 5 days or more, never the water logging rice shoot heart Leaf.

The present invention is further improved technical solution, and the application of machine transplanting of rice rice seedling bed takes " eliminating for zero day " technology, i.e., in rice machine When inserting, be administered in the machine transplanting of rice using dedicated Agent spraying machine, combined remove with 80-100 grams of 70% Wettable propineb powder per acre Careless agent routine dose, drips in rice mechanical transplanting and applies, and to keep after application shoaling layer 7 days or so, only fills and does not arrange, but to avoid water layer Flood rice seedling lobus cardiacus.

It is machine transplanting of rice rice seedling bed, seedling throwing field application that the present invention, which is further improved technical solution, takes " even envelope band kills " technology, i.e., Transplanting, rice transplanting crop field fail to carry out closing weeding in time when planting, wettable with 70% Propineb per acre 5-7 days after throwing cultivation Property 80-100 grams of pulvis combine the mixing of herbicide routine dose to spray, when application, drains water in field, rehydration after application 24 hours.

It is to look into control benefit and control in time that the present invention, which is further improved technical solution: still higher to grass amount after medication twice individually Field, to take the method for controlling of choosing in time, cauline leaf spray, which is mended, to be removed, and serious location occurs to semen euphorbiae, uses cyanogen after being allowed to dry water in field Fluorine grass Recipe prevents and kill off grass by spraying；Serious location is occurred to barnyard grass, uses penoxsuam or oxazole acyl grass after being allowed to dry water in field 80-100 grams of+70% Wettable propineb powder of amine formula prevents and kill off grass by spraying；It is miscellaneous to broad-leaveds such as extremely individual wild water chestnuts, wild arrowheads Serious location occurs for grass, is allowed to dry 80-100 grams of 70% Wettable propineb powder 48% bentazone aqua of combination of mu after water in field 150 milliliters or 46% 150 milliliters of diformazan Bentazon soluble concentrate are watered 30 kilograms and prevent and kill off to grass progress even spraying.

The invention has the advantages that:

(1) Propineb+herbicide is mixed imposes on rice field, ensures herbicidal effect simultaneously, Propineb can effectively prevent herbicide damage It generates.

(2) shift to an earlier date promoting root growth, promote evil, strong sprout, prevention and treatment runt seedling is not sent out, and slow seedling, promoting root growth, strong sprout progress shift to an earlier date 10 days or so, greatly It is big to increase early stage low section available tillering and the later period percentage of earbearing tiller, improve yield and quality.

(3) change the 2-3 application fertilising multi-pass operation of traditional approach, Propineb+herbicide of the present invention is mixed to apply primary behaviour Make, it can be achieved that the unification of " weeding, pest controlling mention seedling, diseases prevention " quadruple effect, saving of work and time abridged edition.
