Description
Technical field
The invention belongs to agricultural technology field, relate to a kind of Semen Tritici aestivi hot-dry wind tolerance spraying resistant to lodging liquor and preparation thereof and use
Method.
Background technology
Hot dry wind also known as " dry wind ", " hot run test ", custom is referred to as " fire south wind " or " windburn ", after being Growth of Wheat
A kind of high temperature, low humidity the comprehensive agricultural meteorological disaster with certain wind-force that phase occurs, is northern China Winter Wheat Area Semen Tritici aestivi
One of meteorological disaster main in production.Hot dry wind is also the environmental stress factor of Semen Tritici aestivi, and Semen Tritici aestivi is during hot dry wind, rising
Intensity increases, and moisture supply-demand imbalance, normal physiological activity is suppressed or destroys, and promotes Wheat in Grain Filling Stage to shorten, mass of 1000 kernel
Decline, can make time serious Semen Tritici aestivi blue or green dry force ripe.General time hot dry wind can make wheat yield 10%～20%, the serious time underproduction
More than 30%.
After Semen Tritici aestivi is endangered by hot dry wind, showing as grain husk shell greyish white unglazed in formalness, awns point is withered to bleach, and the awn of wheat is opened
The angle opened is ascending, and boot leaf moves back Lu, wilting, and cane green grass or young crops is withered, and severe one Jiao's head explodes awns, and stem and leaf is gloomy unglazed.Hot dry wind disaster
Mainly having a three types: 1, the low wet type of high temperature: be characterized in high temperature, arid, have certain wind-force, wind exacerbates dry, hot shadow
Ringing, this weather makes that the dry point of Semen Tritici aestivi, plant be withered and yellow, wheat grain is done not plump and affected yield.It is the main class of wheat district, north hot dry wind
Type.2, dead ripeness type after rain: being characterized in after rain high temperature and the finest, Exposure to Sunlight is strong, and hot blast blows hard, and causes the blue or green withered and dead ripeness of Semen Tritici aestivi.
3, drought wind type: feature is that humidity is low, wind speed big, but daily maximum temperature is not necessarily higher than 30 degree.
Wheat lodging disaster refers to, gives birth to middle and late stage at Semen Tritici aestivi, because climate factor or cultivation step are improper, causes little
Wheat large area is toppled over, and has a strong impact on Semen Tritici aestivi ripe, reduces mass of 1000 kernel, causes a kind of phenomenon of the underproduction.Lodging is that Semen Tritici aestivi is close
Plant high-yield culturing and the serious significant obstacle factor reducing marketing quality.Data shows according to the study: Semen Tritici aestivi is in lodging meeting in boot stage
The underproduction 31%, the pustulation period lodging meeting underproduction 25%, kernel maturity stage lodging the underproduction 12%, even straw bending also can cause and subtract
Produce.
Wheat lodging is mainly affected by the factor of kind lodging resistance, cultivation step and natural disaster.Can be divided into root lodging with
Stem lodges.Root lodging is bad mainly due to root system development, takes root not deep, and secondary root is few and thin and delicate, aerial parts of giving away
Weight and occur.It is the most shallow that generation is primarily due to arable layer, wholely, seeding quality poor etc., cause root system development
Bad, bury shallower, or because early stage is not watered, later stage irrigation amount is excessive, soil layer is wet soft, then meets wind and rain and the lodging that causes.Stem
Lodging is owing to the mechanical tissue of basal part of stem is undeveloped, and first and second internode is long to be caused.Usual reason is because of application rate mistake
Greatly, rich water is sufficient, and particularly nitrogen application is too much, miscarriage, and causes tiller too much, and colony is excessive, and polarization is slow, field
Between strongly fragrant cover, illumination is the most not enough, and basal internode is long, and stalk wall is thin and unreal, and dry-matter accumulation is few, meets wind and rain invasion and attack, the lower portion of the stem
Bend or fracture and cause.
Plant growth regulator, is the class pesticide grown for coordinate plant growth, has sky including synthetic
The so compound of phytohormone similar action and natural phytohormone of extracting from biology.For target plant, plant is raw
Long regulator is the non-nutritive chemical substance of external source, generally can conduct in plant to site of action, with the lowest concentration
Just can promote or suppress some link of its life process, be allowed to the needs to meeting the mankind and develop.
According to the difference of water consumption, pesticide spray can be divided into again Large Copacity spraying (every mu of use water 50～100kg), middle appearance
(every mu of use water is few for amount spraying (every mu of use water 10～30kg), low-gallonage spraying (every mu of use water 1～10kg) and ultra-low volume spray
In 1kg).Conventional dispenser typically uses medium volume spraying.
Along with the development of unmanned air vehicle technique, the unmanned plane during flying dispenser risen in plant protection field, to the use of pesticide
Bring new revolution.Unmanned plane dispenser has the advantages that effect is high, expenses for prevention and control is low, dosage is few, especially executes in paddy field
Medicine, extreme terrain dispenser, concentration Unifying control dispenser field, compared with traditional insecticide-applying way, have obvious advantage.But nothing
Another feature of man-machine dispenser is that water consumption is few, when conventional pesticide is used for unmanned plane dispenser, and low-gallonage spraying to be used, this
Time drug effect be difficult to ensure.Droplet drift, droplet when frequently resulting in the drug effect reduction of medicament, dispenser volatilize, rotation oar gas
The problems such as stream impact.
Existing plant growth regulator formulations mainly includes powder, water preparation etc., and plant growth regulator is ultralow
Volume sprays liquor has no report both at home and abroad.
Typically by screening, volatility is low, lightning is high, molten to crop safety good to former medicine dissolubility for ultra low volume liquids
Agent, is not watered during dispenser, but straight with ultra low volume sprayer tool, low-gallonage spraying apparatus or ultra-low volume electrostatic spray apparatus
Connect and use.Ultra-low volume spray is owing to spraying from leaving aerosol apparatus without high volatile ingredient, its size of medicinal liquid and quality in droplet
Head does not has significant change during arriving target, decreases volatilization and the drift of medicament.Droplet is tiny and uniform, it is possible to notable
Improve the deposition of medicinal liquid.Owing to using without being watered, ultra-low volume spray liquor is suitable for water resource shortage, pest and disease damage collection
Middle fulminant large area occurs and dispenser on a large scale in needing the short time, and specialized Unifying control dispenser, the most ultralow
Volume sprays significantly reduces the labor intensity of operator.
The conventional spraying methods spraying commonly used regular dosage form of current domestic plant growth regulator, is that plant is raw
Long regulator preparation carries out medicament sprinkling after diluting with a large amount of water, and this prevention and controls exists various problems:
1. conventional spraying work efficiency is low, and work efficiency is only 2～5 mus/day the most per capita, it is difficult to meet the needs of implantation in large scale,
Along with domestic land transformation policy is to implement, soil presents the trend of intensive management, occurs that increasing agricultural planting is big
Family, crop contiguous plant area increases；And along with China's aged tendency of population and the appearance of recruitment famine, labour force is increasingly becoming dilute
Lacking resource, human cost improves constantly, and agriculture production cost continues to increase, and adds the seasonal obvious of agricultural production, medicament
Sprinkling generally requires uses substantial amounts of manpower at short notice.
2. conventional spraying needs substantial amounts of water, and usual water consumption reaches 10～30kg, and is much lacking away from water source and arid
The area of water, reduces water consumption spraying and can not reach preferable pharmacy effect effect.
3. conventional nebulization uses medicament lightning, volatility do not meet low-gallonage spraying dispenser requirement.
