Technical field
The present invention relates to the inoculation method that a kind of inoculation method of upland cotton, particularly a kind of upland cotton efficiently increase production, category
In agricultural plant Cultivating techniques field.
Background technology
Upland cotton (scientific name:Gossypium hirsutum Linn.) Malvaceae annual herb plant, 0.6-1.5 high
Rice, sprig is dredged and is become mildewed.Ye Kuo is avette, and base portion is heart-shaped or heart shaped butt shape, and sliver triangular shape wide is avette, above it is near without hair, under
Dredge villosity in face;Petiole is dredged by pubescence;Stipule ovate crescent, it is caducous.Hua Dan is born in axil, and bennet is generally slightly short compared with petiole;
Squamella separates, and base portion is heart-shaped;Calyx cup-shaped, sliver triangle has echinid;Floral white is faint yellow, and pale red or purple are become afterwards
Color;1.2 centimetres of stamen column length.Capsule oval, has beak, 3-4 rooms;Seed is separated, oval, has white cotton wool long and canescence
The short cotton wool being not easily stripped.
There are 7 Semi-wild species (race), i.e. Ma Lijialangte cottons (Marie-Galante), Bao Moer in the cotton seed of land
Family name cotton (Paimerii), not Li Ershi cottons (Morrilli), sharp class cotton (punctatum), Yucatan cotton (Yucatanense),
Li Qimengdeshi cottons (Richmondii) and broad-leaved cotton (latifolium).Cultivar is typical annual undershrub,
Plant is tall and big, healthy and strong (plant height 100cm or so), and blade is roomy, 120-220 days breeding time.
One of tetraploid Shoot apex, scientific name GossypiumhirsutumL..Chromosome number 2n=4x=52.Originate in
The highland in Central America Mexico south and Caribbean Zhu Dao, also known as Upland cotton.It is suitable in vast subtropical zone, Temperate Region in China kind
Plant, be to be distributed widest cotton seed in the world.
First, the upland cotton of Tetraploid 1.:Leaf is larger, and 3-5 splits, and splits scale length not as good as the 1/2 of length of blade, there is the outer honey of bract
Gland, corolla is larger, milky, and generally without red heart, bell is big, and oval, bell face body of gland is few, more smooth, seed median size, typically
It is hair seed, fibre length 21-33mm, fibre fineness is 4500-7000m/g, fibre diameter is 13.5-19 μm, monofilament strength
It is 3.5-4.5g.
2. sea island cotton:Ye great, 3-5 split, and split scale length more than length really 1/2, there is the outer nectary of bract, and corolla is big, deep yellow
Color, there is red heart, and bell is medium, oval long, and bell face body of gland is more, and coarse, seed is larger, mostly light seed or end hair seed, fibre length
33-45mm, fibre fineness is 6500-9000m/g, and fibre diameter is 12-14.5 μm, and monofilament strength is 4.5-6.0g.
Upland cotton can often run into during cultivation, the problems such as temperature, soil moisture content, pest and disease damage, accordingly, it would be desirable to right
Each process of production properly protects, and its yield and quality is obtained lifting, and existing upland cotton is cultivated does not have systematic side
Method, it is therefore necessary to a set of rational upland cotton is provided and cultivates solution.
The content of the invention
It is an object of the invention to provide the inoculation method that a kind of upland cotton is efficiently increased production.
Disclosure sets forth the inoculation method that a kind of upland cotton is efficiently increased production, comprise the following steps successively:
(1) choose seeds:The tetraploid parent species with resistance are chosen as original seed, its mature sporophore is taken, it is floating by salt solution
The method of choosing is chosen seeds, and after seed selection, is dried more than 35 days in the sun;
(2) soil pretreatment:Prepartion of land, washes flat method and is processed using laser, is then plowed and is raked the soil level,
For the first time plow, the autumn turns over, and ploughs deeply below 30cm, builds low ridges between paddy fields and discharges water, and discharges water and is deep to 20-25cm, make soil salt alkali content reach 2% with
Under, saline and alkaline to penetrate into below 30cm, plow 25-26cm for the second time, upper fertilizer before plowing, nitrogen-phosphorus-potassium compound fertilizer 40kg/ mus, urine
Plain 3kg/ mus, native 60kg/ mus of phosphate fertilizer, uniform cloth is spilt in soil everywhere, if described soil sand ground is harrowed three times, if blue clay ground
Rake more than four times, makes soil block fragmentary;
(3) Seeds preprocess:50% 150 grams of carbendazol wettable powder, 20% 250 grams of methylarsonic acid zinc wettable powder
It is well mixed with 5 grams of fine earths or plant ash, is then mixed thoroughly with 50 grams of cotton seeds, is sowed within three hours after agitation;
(4) sowing and management:Using the mulch film of 1.25m, line-spacing is that 51.5cm+51.5cm+50cm × 3 are a width film, strain
Away from 11 centimeters, mu 11862 plants of strain number of theory, or using the film of 2m, line-spacing is 59.3cm+59.3cm+50cm, spacing in the rows is 11 public
Point, mu 10580 plants of strain number of theory is filled the gaps with seedlings in 18~24 days after sowing, and sowing time is 30 days, in described sowing
In phase, the humidity of soil at the 10cm of underground need to be ensured more than 78%, meanwhile, set gutter, prevent ponding reach ground with
Lower 15cm, cotton plant is highly controlled between 80cm~1m, and fruit tongue averagely reaches 11 tongues and starts to pinch;
(5) expelling parasite scheme:Cotton age reach 50 days, 120 days, 200 days when, carry out expelling parasite treatment, matched using unified
Pest repellant carry out expelling parasite;
(6) harvest:Harvested using workalike cotton collecting cart, be placed in after harvesting under sunlight and be exposed to the sun 7-10 days,
And carry out turn-over treatment;
(7) finished product storage:The cotton that will be handled well is put into warehouse, and the air humidity in warehouse is controlled below 65%, and
Daily 5~12 times of air exchange amount is carried out using blower fan.
Further, the weight saline ratio that described brine floatage is used is for 1.85~3 portions of salt:100 parts of water, it is described
Saline to being completely dissolved.
Further, the pest repellant of described unified proportioning, its proportioning is:5% 75-112.5 grams of 5 percent of hexaflumuron emulsifiable concentrate/public affairs
Hectare;Pungent 180-240 grams/ha of the missible oil of 20% fluorine bell;20% goes out 100-150 grams/ha of pungent missible oil;25% decamethrin
100-150 grams/ha.
The positive effect of the present invention is:
1st, by the integrated optimization to cotton culture technology scheme, cotton planting is made with more systematicness, while can carry
The yield and quality of the cotton that height is planted.
2nd, it is that cotton planting sets good cultivation basis, by salt solution by selection and the pretreating scheme of supplying mother seed
Seed selection and Seeds preprocess, can improve the survival rate of seed, reduce the possibility occurrence of disease, increase economic efficiency.
3rd, carry out rational proportion by pest repellant, make its scope of application wider, can full protection insect, reach raising produce
The effect of amount.
