Description
Technical field
The present invention relates to agricultural water conservation technical field of cultivation, especially a kind of salt-avoiding species for emergence of corn water are planted dedicated
Equipment and its type of seeding for keeping away salt corn specifically keep away salt seeder for a kind of corn and its keep away the type of seeding of salt corn.
Background technique
In Bohai Rim winter wheat and summer corn two crops a year planting area, the lower need of During Growing Period of Winter Wheat rainfall
It irrigates and is just able to achieve high yield and stable yields, since the area lacks fresh water, usually irrigated, great Liang Yan using brackish water (being less than 5g/L)
Study carefully and shows that brackish water irrigation wheat has certain production-increasing function compared with dry farming.But salinity is in soil after brackish water irrigation
Middle accumulation, under the influence of stubble corn emergence.It in addition corn seeding phase soil moisture content is often very low, cannot emerge, need in time
It irrigates.
Studies have shown that summer corn after planting needs the fresh water irrigation ability with 70mm or more when winter wheat brackish water irrigation
Influence of the salinity of Soil accumulation to emergence of corn and seedling growth can be alleviated.One time irrigation water capacity is big.Cause irrigation water
Waste, simultaneously because unit area irrigation volume is big, causes the watering period long, postpones Corn Irrigation and emergence, influences yield.
So being badly in need of one kind at present is able to solve the above problem, the use of irrigation water is reduced, guarantees that corn is normally emerged and grows sturdily
The corn of strong growth keeps away salt type of seeding and device to solve problem above.
Summary of the invention
In view of this, the present invention provides one kind to be able to solve the above problem, the use of irrigation water is reduced, is guaranteeing corn just
The corn grown up strong and sturdy of often emerging keeps away salt seeder.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of corn keeps away salt seeder, including drawing head and corn keep away salt seeder, and the drawing head is detachably connected liquid
Undercarriage is pressed, the hydraulic lift frame is kept away salt seeder with corn and is fixedly connected, and it includes device master that the corn, which keeps away salt seeder,
Body, Seeder, seed opener sow irrigator, land wheel, coverer, seed pressing wheel and film-covering mechanism；
The seed opener is fixed on the front end of described device main body, and the Seeder is fixed on described device master
The middle part of body, between the fixed seed opener of the sowing irrigator and the Seeder, the land wheel is fixed
In described device main body two sides, the coverer, seed pressing wheel and film-covering mechanism are sequentially arranged in the rear end of the Seeder.
The present invention directly can will carry out fresh water to the region of sowing seed in corn seeding and pour using sowing irrigator
It fills, reduces the waste of irrigation water, also effectively can supply fresh water to kind of plant hole, guarantee that the moisture in kind of plant hole region is sufficient,
The salinity of planting area is reduced, can guarantee the germination and the growth demand at initial stage of corn；The present invention can be realized trench digging, fill
It irrigates, earthing, manpower and the configuration of the present invention is simple are saved in smooth integration operation, and practicability is high.The present invention can in high salt
Realize the target that corn planting is water-saving and increases production in area.
Further, the seed opener is multiple, horizontal Tile arrangement, ditching depth 4-8cm, width 5-
7cm。
The present invention can be realized multiple row planting, ditching depth 4-8cm, width be 5-7cm be conducive to corn germination and
Early growth, this depth and width are also beneficial to the pouring of sowing irrigator, and the amount of being filled with water of the depth and width of trench digging just can
Reduction salinity is enough played, meets the needs of Maize in Earlier Stage growth is to moisture, decreases the waste of iirigation water source.
The sowing irrigator includes water tank, low pressure water supply line, watering pipe, time switch valve；
The low pressure water supply line uses trickle irrigation or irrigation pipe, the low pressure water supply line and the storage tank inlet end
Connection, the watering pipe is correspondingly arranged to be multiple with the seed opener, and one end is connect with the water tank outlet end,
The time switch valve is arranged in the water tank and the watering pipe junction.
The present invention utilizes existing trickle irrigation or irrigation pipe, and trickle irrigation or irrigation pipe pressure are adjusted to low pressure, are connected to
Storage tank inlet end, trickle irrigation or irrigation pipe are moved with seeder at seeding time, are able to continuously offer water source of fresh water.It can also
To expand water tank, limnimeter is set in water tank, user is reminded after water level decreasing, user utilizes trickle irrigation or spray
Fill pipeline water filling.
Further, the Seeder includes seed-box, seed idler wheel and delivery pipe, the seed idler wheel rotation
Be connected to the lower part of the seed-box, and be connected to the seed-box, the delivery pipe be set to the seed idler wheel lower section and
It is connected to the seed idler wheel, the quantity of the delivery pipe and position and the seed opener correspond.
Seed idler wheel is circle in the present invention, and surface is provided with seed trough, and when seed idler wheel rolls, seed is followed down
It falls, is capable of forming stable plant spacing, the quantity of delivery pipe and position and the seed opener correspond can be with
Guarantee that corn seed is directly fallen in the ditch that seed opener opens up, time switch valve matches with seed idler wheel, periodically opens
The switch time of closing valve is corresponding with the rotation of seed idler wheel, and fresh water can be injected in ditch, then can be corn seed
It is wrapped in fresh water, guarantees the normal sprouting of corn seed.
It further, further include spray equipment, the water tank is provided with Bypass hose, and the spray equipment is fixed on institute
It states the side of Bypass hose and is symmetrical arranged.

A kind of type of seeding keeping away salt corn keeps away salt seeder using a kind of above-mentioned corn and carries out sowing plantation, including such as
Lower step,
1) choose seeds: selection full grains, no disease and pests harm mature corn seed, screen out spare after impurity
2) seed treatment: the corn seed that step 1) is chosen is put into the seed treatment liquid prepared in advance, then
Be put in temperature-changing chamber, control the indoor temperature of alternating temperature be 10~35 DEG C, with the rate of 5 DEG C/0.5h by lowest temperature to the highest temperature into
The continuous alternating temperature of row operates, and takes out seed after processing 2.5h spare；
3) it sows: salt seeder being kept away using above-mentioned corn and carries out sowing plantation, after planting covers mulch；
In the present embodiment, material composition that the seed treatment liquid in step 2) is by following weight percent: glutamine
0.5~1%, carbendazim 0.1~0.3%, sldium lauryl sulfate 0.1~0.4%, manganese sulfate 0.2~0.5%, magnesium sulfate 0.2~
0.5%, chitosan oligosaccharide 1~1.5%, surplus are water.
The present embodiment improves maize seed by the collective effect of unique seed treatment liquid prepared and alternating temperature stress very well
The characteristic of son, improves its vigor, solves the problems, such as that its storage easily causes germination percentage low, while enhancing the salt tolerant of seed again
Performance improves the quality of seedling；Special processing is carried out to the seedling of incubation, the environment that can enhance seedling well adapts to energy
Power promotes its moisture absorption and nutrient absorption ability, ensure that its survival rate in harsh environment.
In order to compare effect of the present invention, select the corn seed of same kind as plantation object, then in soil total salt
It is planted on the plot that content is 0.50wt%, following table is corresponding correlation data:
In the following table as can be seen that the present embodiment can keep corn seed more preferable after carrying out corn seed processing
Adaptation hypersaline environment, shorten germinating time, increase germination percentage.
Experimental data:
