Description
Technical field
The invention belongs to vinegrowing technical field, and in particular to a kind of grape frost prevention method.
Background technology
" frost " is a kind of diastrous weather phenomenon, is referred in the season of growth, night soil surface temperature or plant hat
0 DEG C or less than 0 DEG C is dropped in the temperature short time near layer, the rapid drop in temperature of plant surface causes the tender portion of grape children
Divide and sustain an injury, plant internal water is freezed, and metabolic process wrecks, cell is extruded and caused harm by ice cube.Hair
During raw frost, it, because low temperature is compromised, is not only because frost causes harm to plant that plant, which is,.Late frost is by cold season
Save the frost occurred to warm transition period in season.It can be drawn from the analysis of Late frost example, Late frost is once obvious precipitation day
Gas process terminates, a kind of short time Low temperature disaster of the sunny appearance of night weather.Due to the invasion of cold air, rainy weather is held
Continuous, the heat energy on ground is relative to be reduced, and precipitation weather stops, and night weather is sunny, and long _ wave radiation makes surface air layer
Turbidity rapid drawdown (radiation cooling), so as to form Late frost synoptic process.Land occupation condition is relevant with the degree of Spring frost, close to big
The vineyard of water body is aggrieved lighter；Throughput is larger, gas exchanges are frequently at mountain top and air port and high-land, it is aggrieved compared with
Weight；It is aggrieved it is most heavy be flat mooring basin, dry riverbed, low-lying land, its reason is that cold air condenses upon hypsography low-lying area；Inversion
Endure cold again, field is endured cold gently；In addition, sandy beach vineyard is aggrieved heavier, and clayed ground orchard is aggrieved relatively light.
More than existing 30 ten thousand mu of Hexi Region of Gansu Province wine-growing, but carry out late frost low temperature freezing-disaster this year and frequently occur, it is right
Grape production causes high risks.The Qilian Wine Company vinifera base of this area in 2004 by decades one meet-
8.3 DEG C of late frost low temperature freezing-disasters, cause then vintage almost have no harvest；On May 12nd, 2012 is again by low temperature Late frost
Evil, yield is greatly affected.Slight late frost has different degrees of generation every year.
It is most of at present to use the methods such as fumigation, irrigation, covering in the prevention of Spring frost.Comparatively, smoke
It is more that cigarette method is applied in frost prevention, but there is also certain limitation, such as fumigation method is in the range of relative closing, in advance
Anti- effect will get well, and in the prevention in large area vineyard, have little effect, meanwhile, fumigation method is affected by wind larger, slightly dries
May result in smog can not be completely covered on crop overhead, and fumigation can only improve surface temperature 1-2 degree, to strong low-temperature frozen
Evil does not have good prevention effect.Irrigation can increase the thermal energy and thermal conductivity of soil；Increase air humidity simultaneously, reduce
Radiation cooling, but be only capable of making ground temperature improve 1 degree or so, and water resource is limited, it is impossible to irrigated in the same time.With grass
Curtain, film etc. are covered, and pre- frost protection effect preferably, but because material and cost of labor are larger, may be only available for compared with small area.
The content of the invention
The invention aims to solve technical problem of the prior art there is provided one kind based on a naked light heating,
The heating of supporting fumigation, and take in the different temperatures stage different measure can effectively improve vineyard temperature, frost preventive effect
Good grape frost prevention method.
In order to achieve the above object, the present invention uses following technical scheme：A kind of grape frost prevention method, this method bag
Include following steps：
A, preparation frost prevention material：The culled wood for a naked light and the fumigation material for fumigation are received in advance
Collection storage, unified management.
B, making smoke agent：Sawdust is shone into dry doubling sieving, sawdust, ammonium nitrate phosphorus, Cosan, waste diesel are then mixed equal
It is even, wherein weight percent content shared by each raw material is sawdust 55-65%, ammonium nitrate phosphorus 15-25%, Cosan 5-15%, waste diesel 5-
15%, dispense storage after being well mixed.
C, temperature detection：The prediction for strengthening frost with local meteorological department works, while with temperature monitor pair
The temperature in vineyard is detected on the spot, and temperature drop situation is grasped in time.
D, frost prevention arrangement：Frost arrive before according to wind direction, the physical features in vineyard and area by fumigation material, smog
Agent and culled wood for a naked light are arranged, and fumigation material is in heaps to be placed on around vineyard, and fumigation material is per heap 20-
30kg, heap is away from 10-15m；Smoke agent is placed in vineyard；Culled wood for a naked light is in heaps to be placed on around vineyard,
Culled wood is per heap 180-220kg, and vertically and horizontally heap is away from 55-65m.
E, frost prevention：Fumigation material and smoke agent igniting are subjected to fumigation when ground temperature temperature is down to 2 DEG C；When ground temperature temperature
When degree is down to -3 DEG C, culled wood, naked light heating are lighted.
Further, fumigation material is the mixture of stalk, hay, sheep manure and fallen leaves in the step A.
Further, weight percent content shared by each raw material is sawdust 60%, nitre when smoke agent is made in the step B
Ammonium phosphorus 20%, Cosan 10%, waste diesel 10%.
Further, a smoke agent is placed on every two mu of ground in vineyard in the step D, and the specification of smoke agent is
25cmX15cmX30cm, each smoke agent can produce 10-15 minutes dense smoke.
Further, culled wood flame height is 14-16m in the step E, and ignition time is 25-35 minutes.
The present invention has the advantages that compared with the prior art：It is of the invention main based on a naked light heating, it is supporting smoked
Cigarette lifts the temperature in vineyard, and in different temperature stages, takes different temperature measures for improvement, the heating of point naked light and fumigation
Heating cooperates, and overcomes the restriction that frost is brought to grape industry development, compensate for taking single measure in the prior art
Deficiency, the present invention effectively prevents the invasion and attack of frost, particularly evident particularly with low temperature Spring frost preventive effect, it is ensured that
The yield of grape.The present invention is easily obtained with material, cost is relatively low, with good application prospect and use value.
Embodiment
With reference to specific embodiment, the invention will be further described.
