Wheat production reason
1, unfavorable meteorological factors
Since mid-april, mengcheng wheat enter full panicle to Yang flowering, from the perspective of the meteorological factors of meteorological department provides, mengcheng wet weather, the more the light is relatively insufficient, the overall low temperature, soil moisture on the high side, after the rainy day temperature higher, falling wheat root vigor, wheat plant appear different degrees of premature aging phenomenon, has seriously affected the normal of wheat grouting, causing the deterioration of wheat grains.
2, 3 factors
According to the county plant protection unit field investigation, mengcheng wheat 3 damage: yannong 19 wheat varieties BingLi rate is 1.9% on average, the highest BingLi rate 2.76%;Other varieties average BingLi rate 9.26%, the highest BingLi rate is 18.2%, the county weighted average BingLi rate was 3.01%.Affected by heavy wheat, wheat actual production will drop by about 3%.
3, lodging factors
Wheat in filling stage, mengcheng successively appeared six different rainfall weather, accumulative total rainfall of 95 mm or more, than perennial distinctness, accompanied by varying degrees of wind, every time after the rain in varying degrees of lodging phenomenon, ear of wheat grain Numbers per spike, due to the influence of different level.Rainy weather during wheat harvest, harvest and of wheat yield, quality were caused by the influence of different level.
Wheat production preventive measures
1, the main measures of drought resistance
In the long run, it is to do well the basic construction of farmland, water conservancy, 2 it is drilling Wells, part three is to sprinkler irrigation;Look from the front, one is to pay special attention to the large tractor shall autumn ploughing, 2 it is to choose the varieties with strong drought resistance, three is to use KangHanJi.We five dalian pool is ten years nine spring drought, drought, a serious threat to wheat production to high yield of wheat, is necessary to solve the problem of drought.
2, to set up the cooperative, implementation of scale operation
With a large tractor shall autumn ploughing, deepen the depth of the requirements and avoid the trenches, improve the quality of soil preparation and create good conditions for wheat growth and development.Is beneficial to uniform soil preparation at the same time, fertilization, planting, unified management, unified harvest.
3, should choose late prophase drought resistance, resistance to wet, strong gluten or super steel of high quality wheat
Dragon wheat 26, dragon wheat 30, no. 10, radial wheat 12, dragon radial m 18, in the promotion of these varieties at the same time, to improve the breed of purification and rejuvenation.
4, to promote "early in the morning, projects, two autumn cultivation mode
"Morning" is early sowing, must be timely early sowing."Projects" is high density, high fat, solve the density is to use birch heilongjiang province farming machinery co., LTD. Production of 2 BSW - 5.4 sowing wheat seeder, changing the single drilling over the past 15 cm to 10 ㎝ single seeding, ha density increased to 750-750, density than in the past, an increase of 2 million plants/ha.High fat: wheat because no farmyard manure can offer, plus by improving the sowing method, increasing the density, so we must improve fertilizer surueyed.In terms of general plot, mu fertilizer rate will reach 60.71 kg, or scalar N14P14K6.NPK ratio 1:1:0.4.Layered fertilization by installments."Two autumn" is the autumn ploughing, fall fertilization.The autumn soil preparation is the key to keep moisture, FuQiu soil preparation can do autumn rain in spring, spring drought fall prevention.Autumn is three-quarters of the fertilization fertilizer (diammonium 22.8 kg, urea, 19, 8.8 kg potassium sulphate) fall is almost 12 ㎝ deep freeze.Remaining 1/4 fertilizer consumption (diammonium 7.6 kg, 4.6 kg urea, potassium sulfate 2.9 kg) when the next spring sowing, fertilization seeding depth of 7 cm, crackdown after 5 cm.Conditional place on wheat jointing stage after urea best again, this is the high yield of wheat fertilization methods.
5, to do well the survey before sowing
Understand what's its use of herbicides, in order to avoid adverse effect on the crop of wheat.
6, good seed treatment
First the crushing grain with gravity type grader, immature grain and impurities to are selected, then grading seed selection, made of large, because of the large arch soil ability.Selection of seed with 0.3% 0.3% thiram and wheat xing, scattered smut, and prevent root rot.
7, machinery maintenance standards
To ensure the power is in good working order, planter in seed metering tank round cup inside the same length, distributing intact, delimit printing machine going to determine through meter standard installation, opener to install spacing is consistent, spring pressure to agree to sowing depth, transmission device, landing gear to be flexible, all the parts to smooth the operation.
