Some column problems.
The invention will be described in further detail below:
One, the winter wheat sowing time suitably postpones
Proper seeding is that winter wheat emergence rate is promoted to improve, and forms the key technology of strong sprout before the winter, and then is the time of infertility
Growth and development and high yield good harvest lay a solid foundation, with the variation of global climate, autumn and winter climate warming oneself at the fact, date of seeding, is partially early
Cause the development of winter wheat each breeding time have it is different degrees of the growth and development of wheat can be adversely affected in advance, it is small
Wheat growth is too fast to cause cold performance to reduce, and is subject to freeze injury and cuts waste soil fertility.Early sowing also will affect the root growth of wheat, out
Existing underground is long, ground prosperous growth " false prosperous seedling " phenomenon, easily the later period is caused to lodge.Winter wheat sowing requires daily mean temperature to stablize
Dropping to 18--16 DEG C, 2010 2009 Huang-Huai-Hais are with Henan Xinxiang, for Shandong Feicheng, Hebei Yongnian, the 1st week October
Temperature on average is respectively that 22.4 DEG C, 21.8 DEG C, 21.5 DEG C, 2013 and 2014 Jinan, Shandong Province temperature on average in first week October are
22.1 DEG C, it is above the suitable temperature of wheat cultivation requirement, if the winter is sowed before and after 1 day October also routinely in Huang-Huai-Hai
Wheat, then date of seeding, is partially early；Late October, above-mentioned four ground temperature on average in the 1st week October is respectively 15.6 DEG C, 16.2 DEG C, 14.9 DEG C,
16.4 DEG C, be suitable for sowing wheat.
Two, dynamic occurs for the field of big fringe amur foxtail
Investigation examination is carried out in Jinan City, Shandong Province suburbs (36 ° of 72 ' N, 117 ° of 07 ' E) winter wheat field in 2013-2015
It tests, it is summer corn-winter wheat rotation plough land that the big fringe amur foxtail in experimental plot, which occurs seriously, and tillage method is the shallow rotary tillage of straw-returning.Two
Year test respectively on October 3rd, 2013, on October 8th, 2014 artificial seeding's wheat, kind is Jimai 22, and application rate is
202.5 kg·hm-2, harvest time is respectively on June 2nd, 2014, on June 15th, 2015.Weeding is not used during test
Other weeds are manually pulled out in agent.
For experimental investigation the result shows that before first crop crop harvest, the big fringe amur foxtail of September early and middle ten days has a small amount of emergence in field,
But as the big fringe amur foxtail that soil cultivating is largely emerged before wheat cultivation is dead or is buried, after farming operation, that is, have
Big fringe amur foxtail emergence.As shown in Figure 1, all temperature on average between 22.1-14.6 DEG C, see by big fringe in early October to the last ten-days period
Wheat ma's number of emerging is higher, adds up 748 plants of m of emergence-2, account for the 61.0% of entire Growing season output of seedling；To mid-November, Zhou Pingjun
Temperature is down between 10.9 DEG C, 1116 plants of m of the accumulative emergence of big fringe amur foxtail-2, account for the 91.0% of entire Growing season output of seedling.From
Early October to mid-November after soil cultivation is the big fringe amur foxtail emergence peak phase.Most one weeks wherein emerge in October
The last ten-days period, all temperature on average are 14.6 DEG C, 262 plants of m of emerging altogether-2, account for the 21.4% of entire Growing season output of seedling.Then with gas
Temperature reduces rapidly, and big fringe amur foxtail emergence is also reduced rapidly.To mid-December, all temperature on average is down to 3.3 DEG C hereinafter, big fringe
Emergence terminates before the amur foxtail winter.Next year 1-2 months, all temperature on average was between 2.7-4.2 DEG C, no big fringe amur foxtail emergence.March
Part, with the raising of temperature, all temperature on average starts above 4.7 DEG C, and big fringe amur foxtail has fragmentary emergence；Into after April, greatly
The emergence of fringe amur foxtail Growing season terminates.From emergence sum it is found that output of seedling accounts for entire Growing season emergence always before the big fringe amur foxtail winter
The 98.6% of amount, spring emergence only account for the 1.4% of entire Growing season emergence total amount.
Three, flame weed eradication and wheat increase yield effect
Big fringe, which is carried out, in Jinan City, Shandong Province suburbs (36 ° of 72 ' N, 117 ° of 07 ' E) winter wheat field in 2014-2015 sees wheat
Ma's prevention and control test, is divided to two processing, application rate is respectively 202.5 kghm-2, 4 repetitions of each processing, each replicated plot
Area is 100m2(10m × 10m), processing 1 are traditional October 3 sowing time, and the entire big fringe of wheat growing season not prevention and control sees wheat
Ma manually pulls out other weeds.Processing 2, agricultural land soil water-holding capacity is 72% before farming, is conducive to the emergence of big fringe amur foxtail, is tried
After testing farming operation, big fringe amur foxtail starts to sprout emergence, weed eradication is carried out using flame weed eradication method after 20 days, with October 23
Sowing.Herbicide is not applied in experimental plot, manually pulls out other weeds, other field management normal managements.It investigates and sends out to harvest time
The density for now handling the big fringe amur foxtail in 1 field is 181 stem m-2, 2 Field densities of processing are 26.8 stem m-2, handle 1 and processing
2 wheat average products are 4700.4 kghm-2, 6531.5 kghm-2.The patent the method sees wheat to big fringe
The anti-efficiency of ma reaches 85.2%, makes wheat increase yield 28.0%.
Table 1: control effect of the flame weed eradication to weeds
Four, big fringe amur foxtail constitutes wheat yield and influences
Investigation examination is carried out in Jinan City, Shandong Province suburbs (36 ° of 72 ' N, 117 ° of 07 ' E) winter wheat field in 2013-2015
It tests, is summer corn-winter wheat rotation plough land, tillage method is the shallow rotary tillage of straw-returning.Test was respectively at October 3 in 2013 within 2 years
Day, on October 8th, 2014 artificial seeding's wheat, kind is Jimai 22, and application rate is 202.5 kghm-2, harvest time point
Not Wei on June 2nd, 2014, on June 15th, 2015.In conjunction with the method for artificial infection, the big fringe amur foxtail density in field is finally arranged
Density is 0,10,20,40,60,120,210,240,330 and 420 plant of m-2Different disposal, 4 repetitions of each processing.Cell with
Machine arrangement, 1 m of plot area2(m of 1 m × 1).Before big fringe amur foxtail divides the winter in experimental plot, 3 early spring, period of seedling establishment final singlings,
According to the slightly above setting preliminary final singling of density before winter, the early spring, period of seedling establishment determine the practical strain density of big fringe amur foxtail.Before harvesting wheat
10 d, big fringe amur foxtail no longer change Wheat Yield Influence substantially, extract each cell weeds, the final stem number of investigation weeds and fresh
Weight.When harvesting wheat, the indexs such as investigation wheat number of productive ear, grain number per spike, mass of 1000 kernel, cell production, comparative analysis difference weeds
Wheat yield between density processing analyzes big fringe amur foxtail and endangers the influence constituted to wheat yield.
As shown in table 2, the changing rule of wheat yield and big fringe amur foxtail generation density are negatively correlated, when big fringe amur foxtail
Density is 10 plants of m-2When, wheat yield with check plot occurs without big fringe amur foxtail compare and significantly reduce, output per hectare is
57373.7 kg, loss late 4.6%；When big fringe amur foxtail density is 240 plants of m-2When, the output per hectare of wheat is
3689.0kg loss late 52.3%；When big fringe amur foxtail density reaches test 420 plants of m of maximal density-2When, wheat it is every
To 2641.0kg, loss late is up to 65.8% for the hectare yield underproduction.
As shown in Table 2, as the increase of density occurs for weeds, wheat spike density is reduced obviously, when weeds strain density is from 0 liter
To 240 plants of m-2When, wheat spike density is reduced to 426.8 ten thousand fringes from 669.3 ten thousand fringe of per hectare, reduces 36.2%.When weeds strain
Density reaches 420 plants of m-2Shi little Mai spike density is 299.6 ten thousand fringe of per hectare, reduces 55.2%.Different densities weeds and wheatear
The linear fit equation of density relationship.Equation and R2Respectivelyy = -0.0117x + 5.286, R2 = 0.9572.Wheatear is close
Degree reduces with the increase of weed density.Influence in conjunction with big fringe amur foxtail to wheat yield rate, it can be seen that big fringe sees wheat
Ma reduces the main path that wheat spike density is yield effect in the influence to wheat yield.
Big fringe amur foxtail density increases to 420 plants of m from 0-2, wheat grains per spike reduces to 20.9 from 28.4, reduces
26.1%.The linear fit equation of different densities weeds and wheat grains per spike relationship.Equation and R2Respectivelyy = -0.0197x+
28.556 R2 =0.877, it can be seen that reducing wheat grains per spike is important channel of the big fringe amur foxtail to Wheat Yield Influence.
Thousand grain weight of wheat changing rule is unobvious between different densities processing, and difference is not significant, mass of 1000 kernel 39.7 ~
45.4 between g.The influence that how many pairs of thousand grain weight of wheats occur for big fringe amur foxtail is slight, and the influence to wheat yield is mainly logical
Crossing influences what wheat spike density and grain number per spike were realized.
Table 2: the big fringe amur foxtail of different densities is to wheat spike density, grain number per spike and the influence of mass of 1000 kernel
Five, big fringe amur foxtail constitutes wheat yield under wheat planting different densities and influences

Comparing with the check plot occurred without big fringe amur foxtail significantly reduces, and output per hectare is respectively 5646.0,6969.8 and
7373.7 kg, loss late is respectively up to 10.4%, 6.6% and 4.6%；When big fringe amur foxtail density is distinguished under 3 wheat densities
For 280,240,240 plants of m-2When, the output per hectare of wheat is respectively 2694.9,2816.5,3689.0kg, loss late difference
It is 57.3%, 62.3%, 52.3%；Wheat cultivation amount is 67.5 and 202.5kghm-2Under planting density, when big fringe amur foxtail density
Reach test maximal density 400 and 420 plant m-2When, the output per hectare of wheat is respectively 2139.0 and 2641.0kg, damage
Mistake rate is up to 66.1% and 65.8% respectively.
In 67.5,135.0,202.5 kghm of wheat-2In the case of 3 kinds of application rates, to big fringe amur foxtail occur density with
Wheat yield rate carries out linear fit, equation and R2Respectivelyy = 0.1349x + 15.027, R2= 0.9385；y =
0.2409x + 7.0166, R2= 0.9823；y = 0.1437x + 11.084, R2= 0.9499.As seen from Figure 1,3
Underproduction rate increases, 67.5 and 202.5 kghm with the increase of weed density under a wheat cultivation density-2Wheat cultivation
Big fringe amur foxtail is two parallel straight lines to the effect tendency line of underproduction rate under amount, and underproduction trend is consistent；When wheat cultivation amount
For 135.0 kghm-2When, with the increase of weed density, Trendline quickly raises up Trendline, wheat yield trend more another two
A planting density is more rapid, this illustrates influence of the adjustable big fringe amur foxtail of the planting density of wheat to wheat yield, closes
Reason dense planting is the important channel for mitigating harm.
