Abstract
The invention relates to the technical field of oilseed rape planting, and provides an oilseed rape cultivation method.The method comprises the step of rotary tillage stubble cleaning performed in a non-tillage farmland, the step of fertilizer application and the step of seed sowing.In the step of rotary tillage stubble cleaning, the rotary tillage depth is 16-18 cm, the rotating speed of a rotary cultivator is smaller than or equal to 600 r/s, and the rotary tillage stubble cleaning step, the fertilizer application step and the seed sowing step are performed at the same time; due to the fact that the rotary tillage depth is 16-18 cm, the rotary tillage depth is just located above a traditional deep tillage layer, and oilseed rape seeds embedded underground in the last year or even multiple years before can be embedded underground for a long time; accordingly secondary faces caused by deep tillage are reduced.Due to the fact that the rotating speed of the rotary cultivator is smaller than or equal to 600 r/s, field straw and weed on the surface of the ground are broken, the seedling effect caused by straw or weed is reduced, meanwhile, the compost speed of straw and weed in the field is improved, and waste materials are recycled as soon as possible.
Description
Technical field
The present invention relates to rapeseed cultivation technical field, in particular to a kind of rape cultivation
Method.
Background technology
China's rapeseed cultivation area and total output all occupy first place in the world, and rapeseed oil accounts for China and eats
More than half of oil, it is seen that Rape-seed production occupies phase in China's oil seed production and people's lives
Work as consequence.And China's rape faces the problem of sternness, main table in evolution
Mechanization degree is low now, thus causes oil agriculture plantation enthusiasm to fall sharply, rapeseed cultivation area
It is degradation trend with yield.
In recent years, along with the tackling key problem of the country each expert of Rape industry system, China's rape is
Preliminarily form the integrated application at Yangtze river basin rape machinery technique for sowing and planting.And north spring rape
District moves northward battle position as China's rape, at present throughout the year plantation rapeseed area 8,000,000 mu with
On, wherein Gansu Province's spring rape and winter rape area more than 200 ten thousand mu, and spring rape mainly collects
In in Minyue County of our province Zhangye Prefecture, Shandan County and morningstar lily army horse-breeding farm, Tianzhu, Wuwei Prefecture,
Hezheng County, state, Linxia and long-pending tor, state, Gannan；Winter rape is concentrated mainly on Zhengning, Qingyang Prefecture
County and some areas, Tianshui, these rapeseed cultivation districts are all due to by its soil morphology, life
The restriction of the factors such as state weather, kind, existing Yangtze river basin rape machinery technique for sowing and planting is in north
Side's spring rape is directly applied and be there is the most serious problem.
Carrying out north spring rape mechanical planting technology is to solve China's edible oil quantity delivered and eat
The necessary ways of oil safety.China is third place in the world big oil seed production state, in recent years, because of oil
Material productivity effect on the low side, peasant planting enthusiasm decline, the whole nation oil plant cultivated area persistently under
Sliding, low yield not before, domestic edible vegetable oil production-demand gap constantly expands.To this end, state
Wu Yuan general office has put into effect in 2007 about the suggestion promoting oil seed production development.Suggestion from
Give full play to the enthusiasm for production of peasant, promote that the angle that oil seed production recovers rapidly development goes out
Send out, put into effect a series of policies and measures.
2007, the situation of domestic and international Vegetable oil market there occurs great variety.By world's energy
The impact that source price sharp rises, under the pulling that bioenergy demand quickly increases, balance
Relation changes.Meanwhile, the soybean main product state such as the U.S., China yield is less than normal level,
There are the market that rise suddenly and sharply in vegetable oil price both at home and abroad.Owing to the 60% of domestic vegetable oil demand depends on
Meeting by import, domestic Vegetable oil market the most merges with international market
Together.Because China cannot break away from the shade that soybean needs import to be brought.China is annual
45000000 tons of Soybean demands have 30,000,000 tons to depend on international market, occupy the whole world 6000
The 50% of ten thousand tons of soybean trade total amounts, the rise of ternational grain price is mainly by soybean shadow
Ring to domestic.
Due to developing rapidly of population growth, living standard raising and aquaculture, China plants
The consumption figure of the oily and feeding grouts of thing increases substantially.
In recent years, China's vegetable oil consumption figure increases by 600,000 tons every year on average, wherein rapeseed oil
Consumption figure account for 1/3rd of vegetable oil consumption figure, produce need particularly thorny, cause oil plant or
The rise of a large amount of import price of vegetable oil.Foreign capitals are just come with preparation, and press forward steadily, the first step
Having knocked soybean down, second step is intended to knock rape down.China's edible oil degree of self-sufficiency only 40% at present.
Fu Ting academician thinks, " degree of self-sufficiency is the safest more than 60% ".It addition, China's feed
Grouts breach is huge, up to 38,000,000 tons.Development oil seed production is imperative, develops rape
Produce one of optimal path being to increase vegetable oil and feed supply.
But China to be developed Rape-seed production potentiality, increase its yield, it is necessary for from source solving
The trend that certainly rapeseed cultivation area falls sharply, this just requires the tillage and cultivation that we face the most now
Technological improvement.Suitable one's respective area is all being studied in various degree by the outer rapeseed cultivation district of Current Domestic
The technology such as rape machine sowing, but rapeseed cultivation is affected by factors such as kind, soil, weathers,
Machine sowing, facility just there is different requirements.China's Yangtze river basin rape is before 2007
The mode having been used up manually transplanting is carried out, and it is greatest drawback that this transplanting is taken a lot of work, and also leads
Cause the principal element that Yangtze river basin rapeseed area falls sharply.In recent years, China's rape production mechanization
The expert of research direction, has succeeded in developing in the Yangtze river basin and has adapted to the facility that the Yangtze river basin is live.
And spring rape district, the north is as the battle position in country's rape future, the stay-at-home work in rural area
Power today less and less, it is badly in need of a kind of rape essence amount associating no-tillage and direct-seeding technology, to change
The enthusiasm of north spring rape growing area oil agriculture, thus reverse the rape kind drastically fallen sharply at present
Plant area, to ensure China's yield of rape.
Summary of the invention
It is an object of the invention to provide a kind of rape cultivation method, this rape cultivation method
There is the secondary seedling of minimizing occur, promote the advantages such as rape root prosperity.
In order to realize the above-mentioned purpose of the present invention, spy by the following technical solutions:
A kind of rape cultivation method, is included in rotary tillage stubble-cleaning step, the trench digging carried out no-tillagely

Fertile step and sowing step synchronize to carry out.
Compared with prior art, the invention have the benefit that the rotary tillage degree of depth is 16-18cm,
This degree of depth is located exactly at tradition deep plough level (20cm) above, and this is conducive to the year before last, buries many years ago
Rapeseed length in underground is embedded in underground, thus reduces the secondary dough caused because ploughing deeply.Secondary
The main producing cause of dough is: First Year normally produces and time dough is after falling to the ground,
After autumn or the beginning of spring, deep ploughing soil, causes its Second Year buried in underground, and buried first
While year seed, with being embedded in the rapeseed of underground before in the soil that deep ploughing is turned over, from
And cause secondary seedling vicious circle.On the one hand carry out rotary tillage stubble-cleaning prior to seeding is to dig to loosen the soil,
On the other hand it is stubble-cleaning, owing to rotary cultivator rotating speed is within 600 revolutions per seconds, the field on top layer, ground
Between stalk and weeds realize granulation, thus reduce the impact of emerging caused because of stalk or weeds,
