Description

A kind of cultural method of cotton

Technical field

The present invention relates to field of agricultural cultivation, and in particular to a kind of cultural method of cotton.

Background technology

Cotton, as one of Important Economic crop, in China, planting range is very wide, the production of cotton and people's daily life It is closely bound up.Therefore, output of cotton is improved, improves cotton quality, to development light and textile industries of China and is uplifted the people's living standard It is significant；The height of output of cotton, the quality of quality, with cotton variety, soil, weather, moisture, fertilising, pest and disease damage The composite factors such as preventing and treating have close relationship, and in the prior art, traditional cultivation is caused using fertilizer phosphorus and potassium element deficiency The relatively low situation of output of cotton.Simultaneously many cotton growers due to picking method it is improper, the cotton quality of harvesting is poor, impurity is more, sells It is low to sell hardly possible, price, has had a strong impact on the due economic well-being of workers and staff of cotton grower.

The content of the invention

In summary, it is overcome the deficiencies in the prior art, the technical problems to be solved by the invention are to provide a kind of cotton Cultural method.

The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of cultural method of cotton, including following step Suddenly：

Step S1, site preparation and fertilization：Select that arable layer is deep, soil property is fertile, light is good, the convenient loam of irrigation and drainage or viscous earth Soil；Soil is deep ploughed 20-30 centimetres before sowing, base manure is used sufficient, can sow in 2-6 months；

Step S2, seeding and seedling raising：Based on live, 20-25 DEG C of use water seed soaking 12 hours, is then dried before sowing, in It vernalization 48 hours under the conditions of 25-30 DEG C, can be sowed when half seed shows money or valuables one carries unintentionally, caves are dug by 80 centimetres of line-spacing, 50 centimetres of spacing in the rows, Per bunch planting kind 2-3 grains, earthing, can transplant within 20 days；

Step S3, field management：First time thinning is carried out when rough leaf is deployed, removes invalid weak seedling, when 2-3 pieces are true Final singling when leaf deploys, one plant of strong sprout is stayed per cave, tillage and weeding is carried out after final singling, answers frequent tillage and weeding later, and earthed up, Vertical pillar, prevents plant from lodging；Every mu imposes 15 kilograms of urea or night soil 500- in final singling, result and the best fruiting period in three times 600 kilograms, to promote to get bumper crops；

Step S4, the prevention and control of plant diseases, pest control：Spraying preventing and treating bollworm is carried out with 1500-2000 times of liquid of 50% phoxim emulsifiable concentrate；With 10% 1000 times of imidacloprid liquid carries out that spraying is anti-to eliminate aphis and thrips；

Step S5, harvesting：Harvest the cotton fruit of maturation in time in mid-September then to November.

The beneficial effects of the invention are as follows：The quality of cotton is not only improved, and during the entire process of cultivation, keeps cotton Colored high yield, high-quality, improve economic benefit, possess good practicality.

On the basis of above-mentioned technical proposal, the present invention can also do following improvement：

Further, mu applies 3000 kilograms of decomposed manure in step S1, burns native 1000-1500 kilograms or potassium sulfate 15 Kilogram.

Further, every mu of 2000 caves of cultivation in step S2.

Embodiment

The principle and feature of the present invention are described below in conjunction with concrete example, the given examples are served only to explain the present invention, It is not intended to limit the scope of the present invention.

A kind of cultural method of cotton, including the steps：

Step S1, site preparation and fertilization：Cotton root system is flourishing, depth of burying, and should select that arable layer is deep, soil property is fertile, light is good Good, the convenient loam of irrigation and drainage or clay loam.Soil is deep ploughed 20-30 centimetres before sowing, uses sufficient base manure, mu applies decomposed manure 3000 kilograms or so, native 1000-1500 kilograms or 15 kilograms of potassium sulfate are burnt, ground is made in the plot of the easy ponding in area of heavy rainfull 1.2 meters of wide high ridges, begin to rehearse between furrow 20-30 centimetres of ditch, hillside fields and the easy plot of draining are using the two kinds of cultivations of flat furrow or high ridge Training form, 2-6 months can be sowed.

Because cotton early growth is slow, to improve the utilization rate in soil, vegetables that can be short with other breeding times and farming Make between thing.Such as preceding Mining potatos or snow bean furrow interplanting, calculating good potato or snow bean will harvest first 20 days and sow, cotton Mining crops before just being harvested during flower emergence.

Step S2, seeding and seedling raising：Based on live, 20-25 DEG C of use water seed soaking 12 hours, is then dried before sowing, in It vernalization 48 hours under the conditions of 25-30 DEG C, can be sowed when half seed shows money or valuables one carries unintentionally, caves are dug by 80 centimetres of line-spacing, 50 centimetres of spacing in the rows, Per bunch planting kind 2-3 grains, earthing.Every mu is planted 2000 caves or so, 0.5 kilogram or so of sowing quantity.Also can nursery field planting.Such as use nutrition Cup nursery capping film, can be transplanted for 20 days or so.It should be noted that prevention cutworm is caused harm after sowing or transplanting.

Step S3, field management：First time thinning is carried out when rough leaf is deployed, removes invalid weak seedling, when 2-3 pieces are true Final singling when leaf deploys, one plant of strong sprout is stayed per cave, tillage and weeding should be carried out after final singling in time, frequent tillage and weeding is answered later, go forward side by side Row ridging, founds pillar, prevents plant from lodging.

Cotton is moisture-proof plant, and plant is tall and big, needs water more, in case of arid climate should respectively pour one after emergence and final singling Secondary water, the phase of bearing fruit of blooming will keep ground moistening, and every mu imposes 15 kilograms of urea or people in final singling, result and the best fruiting period in three times 500-600 kilograms of fecaluria, to promote to get bumper crops.

Step S4, the prevention and control of plant diseases, pest control：The pest and disease damage of cotton is fewer, mainly there is virosis, and insect pest mainly has bollworm, aphid Worm, thrips etc., virosis should put prevention first, bollworm main harm fruit, can use 1500-2000 times of liquid of 50% phoxim emulsifiable concentrate Sprayed, aphid and thrips main harm Fruit pod, can be sprayed with 10% imidacloprid, 1000 times of liquid.

The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
