Results and analysis
The impact of different cropping patterns on wheat, corn yield:
2008-2013 just starts to explore the cropping pattern research that is applicable to 1 year two work of do mechanization operation wheat and corn, adopt 4 kinds of cropping patterns: wait 6: 2 strip type interplantings of 3: 1 strip type interplantings of line-spacing sowing wheat interplanting corn, wheat and corn, wheat and corn, 7: 2 strip type interplantings of wheat and corn, 2012 basic determines optimal mode, and result of the test is as table 1:
Table 1: the impact of different cropping patterns on wheat and corn output
As seen from table: the gross yield maximum of the wheat and corn of 7: 2 strip type interplantings of wheat and corn, than ck volume increase 33.2%, wherein the output of corn is than ck volume increase 56.9%; Next is wheat and corn wide-and narrow-row interplanting in 6: 2, and wherein corn yield increasing effect is not as 7: 2 strip type interplantings of wheat and corn; 3: although 1 wide-narrow row planting wheat and corn gross yield higher than ck, wheat yield is than the ck underproduction 7.4%,, this pattern is unfavorable for improving the output of wheat, finally the most desirable with 7: 2 strip type interplanting effects of wheat and corn.Research shows: wheat adopts wide cut narrow row strip cropping, and a width is sowed 7 row wheats, wheat line-spacing 13cm, bandwidth 78cm, band spacing 50cm, mu sowing 20-22.5kg.At wheat belt interplant 2 row corns, Row spacing of maize 30cm, spacing in the rows 16.7-20cm, mu stays seedling 5000--6000 strain.As Fig. 4: Middle Shanxi wheat and corn is made mechanization interplanting ideograph for 1 year two.
Wheat breed is screening test result relatively:
We test 2008-2010 respectively Changzhi5608, long by 4738, long wheat 6135, comprehensively analyze, and long wheat 6135 is relatively applicable to pattern plantation, and output reaches 520kg/ mu, and tillering ability is strong, the percentage of earbearing tiller is high, resistance to late sowing, precocity, anti-fall.Under pattern, the supporting kind of wheat should possess following characteristics: high yield, high-quality, precocity, resistant to lodging, tiller not necessarily many but stem with tiller and will advance side by side, spend more how in fact, thousand kernel weight is high, grouting is fast.
The comparison of different interplanting corn variety yield result:
2010 we carried out corn variety screening test, that is: long single by 525, first beautiful 335, No. 1, Jin Yang, Zheng Dan 958, Gu Feng 902, kxw116.The results are shown in Table 2.
The different interplanting corn variety yields of table 2
As shown in Table 2: Zheng early 958, longly early 525 show no increases in output than the wide 563.6Kg volume increase 13.8%, 9.8% of the average mu in No. 1, contrast Jin Yang, Gu Feng 902 respectively, first beautiful 335, bis-kind underproduction of KXW116.Comprehensive analysis: the corn variety that is applicable to pattern plantation should possess following characteristics: high yield, stable yields, special precocious, resistance to close, later stage filling intensity large, dehydration fast, resistant to lodging.Zheng Dan 958 stable high yield, but the margin of safety is low, is applicable to the good plot of fertile soil irrigation conditions; No. 1, Jin Yang is high yield but also performance stable yields not only, and the margin of safety is high, is applicable to more large group and selects.
The impact of different planting densities on corn yield:
We adopt Jin Yang No. 1 2010-2013, divide six processing to interplant density test, density processing in 2010: 3000,3500,4000,4500,5000,5500 plants/acre, density processing in 2011: 4500,5000,5500,6000,6500,7000 plants/acre.
As shown in Figure 5, result shows: within 2010, increase gradually trend along with the increase output of density is, 5500 plants/acre of processing output are the highest, per mu yield 667kg, this test fails to find Up limit, and 6000 plants/acre of processing output in 2011 and 5500 plants/acre of processing remain basically stable, be respectively 745kg and 740kg, process the remarkable underproduction for 6500 plants/acre, therefore, ideal density should be that 5000-6000 strain is advisable.
The impact of different sowing dates on corn yield:
We have carried out two kind three dates of seeding split block experiments 2010-2013, are intended to determine when which type of kind sows output higher.Kind is Zheng Dan 958 (mid-early maturity), long single 525 (precocities), point three phase 25/5,5/6,15/6 sowings.Adopt split plot design.
As shown in Figure 6; Result shows: mid-early maturity kind Zheng Dan 958 date of seeding I full maturity and output are the highest, per mu yield 770kg, and date of seeding II is mature on the whole, and date of seeding III can not normal mature.Long single 525 3 dates of seeding of early-maturing variety, all can normal mature, but the highest with date of seeding II output, and date of seeding I, date of seeding II yield variation are not remarkable, per mu yield between 640-670kg, date of seeding III per mu yield is not enough 550kg.
The impact of chemical regulation on Yield Traits of Wheat:
Within 2011, we select two kinds of growth regulators to test respectively, (1) the foliage-spray aqua of " making every effort to overcome short large fringe " before wheat jointing, can increase the grain number per spike of wheat and improve output, with 40ml/ mu spraying effect the best, can improve grain number per spike 1.9g, improve output 96kg, rate of growth is 27.4%.(table 3) (2) wheat late growth stage foliage-spray wheat grain filling treasured, can increase the thousand kernel weight of wheat and improve output, to spray twice best results of 50ml/ mu, can improve thousand kernel weight 6.4g, improves output 162kg, and rate of growth is 46.2%.The thousand kernel weight of the wheat of the processing of (table 4) concentration 65ml/ mu and output rate of growth reduce, and illustrates that to spray wheat grain filling treasured drug concentration too large, are unfavorable for improving the output of wheat.If wheat grain filling is precious and insecticide is used in conjunction with, can realize insect protected and weightening finish double effects.
Table 3 variable concentrations make every effort to overcome the impact of short large fringe aqua on Yield Traits of Wheat
| Process (m1/ mu) | Grain number per spike | Wheat yield (kg/ mu) |
| 20 | 29.5 | 394 |
| 40 | 31.2 | 446 |
| 0(ck) | 28.3 | 350 |
The precious impact of processing Yield Traits of Wheat of grouting of table 4 variable concentrations
The comparison of interplanting corn mode:
Year in-2013 in 2010, we carried out respectively interplanting, seedling raising and transplanting, summer sowing test on seeding method, seedling raising and transplanting effect is pretty good, but labour intensity is large, is not suitable for spread, live substantially can not full maturity, comprehensive pros and cons are ideal with interplanting effect.
Entire mechanization operation:
Wheat cultivation is selected the supporting 18-30 horsepower of " agriculture heartily " board 2BXF-9 type disc type wheat seeder four-wheel tractor, effectively solve the seeding quality problem that stalk blocks up and the outstanding void of soil is brought, results are used general large-scale combine, interplanting corn and management adopt " Wutai Mountain " board 3WG45 Multi Role Aircraft, complete sowing, topdress, the operation such as intertill and clean tillage by exchanging different facility.Wheat stalk is pulverized to cover and is used IE40F-5A type harvester for wheat or gardens shoulder carrying mower, has realized pulverizing covering disposable operation, also can be used for the weeding of corn middle and later periods simultaneously.Harvest corn uses general maize reaping machine.Realize peasant's increasing both production and income under the prerequisite that does not increase labour intensity.
Wheat stays high stubble harvesting and stalk returning to subtract (exempting from) corn intertillage technology:
After wheat maturation, adopt general wheat harvester to stay in time high stubble harvesting, stubble height 25-30cm is advisable, and does not also hinder maize seedling and is as the criterion can receive clean wheat.When corn height of seedling and wheat stubble height is contour or during a little more than wheat stubble height, carry out wheat crushing covering, the standard of covering be crushed stalk in small, broken bits completely, cover evenly.Our past attempts adopts manpower deeply to intertill, the means such as mini-size tillage machine, and effort effect is also undesirable.Within 2011, we use IE40F-5A type harvester for wheat or mower, have realized pulverizing covering disposable operation, and effect is ideal.Be conducive to soil moisture conservation, increase soil nutrient, suppress weeds subtract (exempting from) corn intertill and clean tillage.
Conclusion:
Improve to a greater extent the output of unit are in Central Shanxi, Demonstration And Extension wheat and corn 1 year two do be the most simply, effectively, approach efficiently.The Optimum Planting Models that this area's wheat and corn is done for 1 year two is 7: 2 strip type interplanting patterns of wheat and corn.That is: wheat and corn adopts 7: 2 wide cut narrow row strip croppings, and a width is sowed 7 row wheats, line-spacing 13cm, and bandwidth 78cm, band spacing 50cm, selects long wheat 6135 new variety of wheat, sowing before October 15, mu sowing 20-22.5kg.20-30 day May in the coming year, corn variety was selected Jin Yang No. 1 at wheat belt interplant 2 row corns, corn line space 30cm, and spacing in the rows 16.7-20cm, mu stays seedling 5000--6000 strain.Become assembling at this pattern next part, being aided with wheat stalk pulverizes to cover and subtracts (exempting from) corn intertillage technology, time of infertility chemical regulation technique, entire mechanization operation technique, form this area's wheat and corn and within 1 year two, make complete culture technique system, realize wheat per mu yield 500kg, corn per mu yield 700kg, mu increases income 1000 yuan, and traditional cropping pattern wheat replay soybean is compared, do not increasing on the basis of peasant's amount of labour significantly increasing both production and income; In table 5.
Table 5 wheat and corn is done the interpretation of result of mechanization interplanting engineering test real estate amount for 1 year two
As seen from table: within 2012, experimental field wheat+corn adds up to per mu yield 1256.5kg, than contrast wheat+mu Yield of Soybean 540kg volume increase 716.5kg grain, mu increases income 1083 yuan.Experimental field wheat in 2013 and corn add up to per mu yield 1377.5kg, and than contrast wheat+mu Yield of Soybean 665kg volume increase 712.5kg grain, mu increases income 916 yuan.The result of the test of comprehensive 2 years show that wheat and corn makes mechanization interplanting technology for 1 year two and can increase significantly the output of grain, increases peasant's income.
Wheat and corn is made interplanting pattern for 1 year two, and all there is the research report of related fields on the ground such as China Shandong, Shaanxi, Henan, Xinjiang, because each department weather difference, interplanting pattern and culture technique that different regions adopt respectively have feature.The Middle Shanxi wheat and corn of our research makes to be applicable to the technology of mechanization interplanting for 1 year two, has breakthrough, and has formed the complete culture technique system in this area, but also need deeply careful research at the aspect such as cropping pattern and supporting technology.
Under filtering mode, the output of the desirable supporting kind of wheat and corn on unit are and marketing quality impact are significantly.
In this research we to select the best sowing time of interplanting corn be 20-30 day in May, do not affecting output and be conducive to gather in the crops under the prerequisite of wheat, sowing date for early sowing, can increase output by extending corn growth stage.
