Description

One implantation methods grown cotton
Technical field
The present invention relates to proportion of crop planting technical field, and in particular to the implantation methods grown cotton.
Background technology
The major product of cotton is gined cotton, is textile industry and light industry, chemical industry, medicine and the important source material of national defense industry. Major and minor product volume of the cotton per 100kg biological yields be:Cotton dry stalk 64kg, unginned cotton 36kg;Its unginned cotton can produce gined cotton 11-14kg, Cottonseed 21-24kg;Its cottonseed can produce short flannel 2-3kg, cotton benevolence 12-17kg, cotton seed hulls 4-5kg;Its cotton benevolence can Lipid-producing 3-4kg, Protein 3.5-5kg.These accessory substances are respectively provided with important comprehensive exploitation value.Wherein cottonseed oil contains a variety of unsaturated fats Acid, its aliphatic acid composition and content are close with soybean oil, and its linoleic acid content accounts for 52.2%, in addition to as edible oil, or apply The fine chemical industries such as material, detergent, plasticizer, adhesive, agrochemicals agent, fabric softening, synthetic lubricant fluid it is important Raw material.Using seedbed come nursery more than during current plant cotton, seedling grows 3-5 piece leaves and is just transplanted in arable land after nursery, So cause cotton seedling survival rate low, grain weight wastes more, and output of cotton is low, it is difficult to meet the demand of people.
The content of the invention
In order to solve the above problems, the invention provides the implantation methods that one grows cotton, concrete technical scheme is as follows:
One implantation methods grown cotton comprise the following steps:
(1)Site preparation:To arable land deep ploughing 20-30cm, and every mu is applied to become thoroughly decomposed and spreads farm manure 3000-3500kg, nitrogenous fertilizer 20-25kg, phosphorus Fertile 15-20kg;Fertilizer is sufficiently mixed with soil with rake and arable land is raked;And irrigate moistening arable land;
(2)Dig plantation hook:Treat that antecedent soil moisture can dig plantation hook, plant a width of 10-20cm of ditch, the spacing planted between planting ditch is 60-80cm;
(3)Seed selection:Select the cotton seeds of appearance full grains;
(4)Vernalization:Cotton seeds are soaked 5-6 hours with 50-60 DEG C of warm water, goes after water to use wet cloth boring cover 4-5 hours, puts Cultivated at a temperature of being kept for 30-35 DEG C under ventilated environment, wait can germinate for 1-3 days;
(5)Plantation:The cotton seeds germinateed are placed into kind of planting ditch, bud upward, and on the cotton seeds of germination Earthing 3-5cm;2-5 cotton seeds of every plant of placement, holding spacing in the rows is 60-70cm, and irrigates moistening arable land;Continuously filled after plantation Irrigate wetting arable land 7-10 days;Every mu of sowing quantity is 7.5-10kg;
(6)Select seedling:Until Cotton Seed grows to 3-4 piece leaves, often select good strains in the field for seed and take most strong seedling strain, remove remaining seedling Strain;Apply composite fertilizer's liquid manure, every mu of application 20-25kg in kind of planting ditch soil surface afterwards, and sprinkling is encouraged on cotton seedling 4-8kg/ mus of agent;
(7)Growing season management:Irrigated 1 time per 7-15 day, every 2 fertigation 1 time, fertilising is by 10-15kg urea, 10- every time 25kg composite fertilizers apply;Fertilising intertillage 1 time, loosens the soil 2-3 times between strain every time, and in the ranks pine soil depth is 8-12cm, and loosen the soil 3- between strain 7cm, every time intertillage coordinates weeding, and during which spraying insecticide prevents the generation of pest and disease damage;See that spindling branch is broken early during flower bud phase, to superfluous Bud will be with going out with smearing;Flowering and boll-setting period will pinch point, remove the growing point of stem;Each fruit branch stays 2-3 fruit section when beating group's point;The beginning of autumn Front and rear every mu can apply urea 5-8kg and make caping fertilizer, and the flower bell later stage sprays 1%-2% urea, 0.2%-0.5% potassium dihydrogen phosphates, according to Cotton plant growing way is sprayed 1-3 times, each every mu of sprayable aqueous solutions 50-75kg;In being sprayed on afternoon with fine day, the upper blade back side;Just wad a quilt with cotton Phase root outer spraying 1%-2% urea, 1%-2% calcium superphosphate liquid or 1%-2% phosphorus diamines or 0.2%-0.5% potassium dihydrogen phosphates;
(8)Harvest:Artificial harvesting in time is organized after cotton boll is ripe.
Further, in step(3)Dressed seed before vernalization with the consumption of carbendazim active ingredient 0.5%, more than airtight storage first quarter moon Vernalization again;Or 50kg cotton seeds, airtight storage vernalization again in 10-15 days are mixed using the clear 25% wettable powder 250g of rice pin.
Further, in step(5)Before cotton seedling breaks ground after plantation herbicide described in herbicide spraying be Acetochlor, it is happy Peace, 48% drag-line, 48% trefanocide, 50% prometryn, 25% nitrofen, apply Tian Puzhong a kind.
Further, the step(7)Middle cotton carries out chemical regulation 2-3 times in Sheng flower bud initial bloom stage to the growing way of cotton seedling, 1st time in squaring period, stem 8-10 piece leaves, every mu of use places mepiquat chloride per 1kg water or helps strong element 30-50mg progress to spray leaf Face, the 2nd stem leaf 15-20 piece or so before and after initial bloom stage, every mu of use places mepiquat chloride per 1kg water or helps strong element 50- 100mg carries out spraying blade face, and the 3rd time every mu of use is per 1kg water placement mepiquat chloride after pinching or helps strong element 100-150mg to carry out Spray blade face, spouting liquid is complete wet but do not drip and be defined to be sprayed onto whole strain blade blade face.
Further, the step(8)In remaining green when it is due to become yellow and ripe late-maturing cotton field is sprayed 40% ethephon (CEPHA),2-(chloroethyl) phosphonic acid 100-150g, add water 50- 60kg, concentration be 800-1000mg/kg liquid so that the bell phase shorten 8-15 days, ahead of time maturation blow-of-cottons;While ethephon (CEPHA),2-(chloroethyl) phosphonic acid is sprayed, plus 0.1%-0.2% thiocarbamides together spray to improve effect of accelerating the ripening.
The invention provides the implantation methods that one grows cotton, the present invention is adopted in cotton in seedling stage, flower bud phase, flowering and boll-setting period, the term of opening bolls With the way to manage of science, and using direct plantation rather than first using being transplanted again after the nursery of seedbed by the way of, improve seedling Survival rate, reduce the consumption of seed, effectively facilitated the sturdy growth of cotton plants rhizome, improve flower-setting rate and sit flower product Matter, effectively increases the yield and quality of cotton.
