Description
Technical field
The invention belongs to cotton culture technical field, more specifically relate to a kind of method that is suitable for In Middle And Lower Reaches of Changjiang River cotton low input high-yield culturing in short season, the method is a kind of based on existing cotton variety, live as basis taking the no-tillage summer, shorten the Cotton Production cycle, realize and reduce work and material input, reduce labor intensity, reduce Cotton Production cost, improve cotton planting benefit, eco-friendly cultivation method.
Background technology
Cotton is to concern the most important fiber crop of people's daily life, thereby is also one of worldwide most important economic crops.Cotton Production is occupied very important status in China's national economy, and Cotton cultivated area accounts for 3% of the national proportion of crop planting gross area, but its output value accounts for 10% of the crops gross output value.Textile and clothing taking cotton fiber as primary raw material is exported goods and earned foreign currency annual 1000 hundred million dollars, account for that national annual commodity export earns foreign exchange 1/5.Therefore, Cotton Production is directly connected to the development of Chinese export-oriented economy, is directly connected to the income of vast cotton growers.Visible, Cotton Production is developing china agricultural production, enrich Chinese people's material life, improve Cotton plantation household economy income, increase China's Foreign Exchange Reserve, expand China's Foreign Trade scale has all made significant contribution.But the sustainable development of Cotton Production faces many new challenges.
The one, Cotton Production cycle length, complex management, labour drop into many
Cotton has indeterminate growth habit, so the Cotton Production cycle is long.This is one of cotton self growth and development characteristics, is also one of major reason that in Cotton Production, various contradiction produces.In cotton region, Yangtze River in China basin, Cotton Production is still taking seedling raising and transplanting production model as main, and the general production cycle is 8 months (April – November), and some areas or peasant household even reach 9 – 10 months.
Just because of the Cotton Production cycle is long, so Cotton Production management operation is many, technical sophistication.In all field crops, cotton management operation is maximum, administrative skill is the most complicated.Wherein managing operation comprises: make preparation for ploughing and sowing, do nutritive cube March, April seeding and seedling raising, seedbed management, May whole ground, fertilising, trench digging, transplant, 5 – intertillages in September, weeding, stubble-cleaning, fertilising, change tune, training, ridging, row's stain, drought resisting, diseases prevention and control (wherein many operations also need repeatedly to carry out) such as worms, 8 – repeatedly gather November, airing, classification, tens procedures such as preserve, pay.
Just because of management operation is many, administrative skill is complicated, therefore labour drops into many.30 of every mu of 25 – of Cotton Production recruitment, are approximately 4 times of Wheat Production recruitment, 3 times of corn, 2.5 times of paddy rice, and the Cotton Fields with High Yield recruitment of intensive cultivation is more.Visible cotton is also that in all field crops, the amount of labour used is maximum.
The 2nd, Cotton Production cost rises: labour's labor cost goes up, and material drops into (agricultural chemicals, chemical fertilizer, plastic sheeting for farm use, seed etc.) to be increased, and causes Cotton Production cost constantly to rise, will under cotton planting benefit.
Along with rural laborer shifts to city, rural laborer's labor cost rises steadily.According to investigations, labour's labor cost of general farming activities in 2013 is 120 yuan/people/more than sky, some cotton regions even reach 150 yuan/people/sky or more than; The labor cost of cotton of gathering reaches per kilogram unginned cotton 2.5-3.0 unit.
Cotton is also to need goods and materials to drop into more crop.Taking 2011 as example, every mu needs the materials such as input seed, fertilizer, agricultural chemicals, conditioning agent, weed killer herbicide, plastic sheeting for farm use to add up to 600 yuan of 500 –, and wherein the input of fertilizer accounts for more than 50%.In all fertilizer, amount of application of nitrogen fertilizer maximum, effect the most easily by peasant accept, cotton grower is also ready most applied nitrogen, but the problem simultaneously existing in nitrogen application process also at most, the most outstanding.Therefore, the material in Cotton Production drops into, and nitrogenous fertilizer (using) is the main aspect of principal contradiction.
The 3rd, Cotton Production restraining factors are many, and output, benefit fluctuate larger
Cotton commodity rate, up to 95%, is the field crop that Market Orientation is the highest.Cotton Production is subject to many factors: the one, and the Cotton Production cycle is long, and disaster affects to be subject to that physioclimate, sick worm are caused harm etc., and between the time, output of cotton difference is large; The 2nd, be subject to water and fertilizer condition, managerial skills, input ability restriction, between plantation peasant household, volume variance is larger; The 3rd, Cotton Production wish be subject to ratio of grain and cotton price and last year price of the cotton affect greatly, easily there is increasing pretty in cultivated area, plantation wish, stagnant subtracting, and brings Cotton Production scale to rise and fall indefinite, thus the peak valley that causes output, price and plant cotton benefit alternately; The 4th, cotton price be subject to raw cotton import volume and International Petroleum Price and wollen fabrics international trade factors impact and impact larger.
In addition, the Chinese countryside quantity of labour force is still in further single, labor quality continuation variation of continuous minimizing, the structure of labour force; Meanwhile, agriculture arable area reduces, and prices of the means of agricultural production goes up, labor cost rises, and causes Cotton Production (comparison) economic benefit to glide.On the other hand, in Cotton Production, the improper input (quantity, method, period) of large quantity of material, causes physical waste general, and environmental pressure increases, and widespread pollution from the overuse of fertilizers and pesticides in rural area increases the weight of.Therefore, actively inquiring into and save management recruitment, reduce labour intensity, reduce that material drops into, raises labour efficiency, stable increase farmland output, the high-yield high-efficiency cultivation technology that operation is simple, is the effective way addressing the above problem.
Research shows, cotton development stage has plasticity, and it raises and shorten with temperature; The accumulation of cotton living beings is the basis that output forms, and its quick accumulated phase originates in initial bloom stage; Cotton Nutrient uptake is the basis that living beings form, and its quick accumulated phase originates in initial bloom stage, slightly early than living beings accumulation; In the situation that fertilizing amount is certain, cotton biological quality in early stage and output negative correlation; Under existing kind and culture technique condition, output of cotton depends primarily on unit are and becomes bell number, and irrelevant with single-strain bell-forming number; No-tillage and direct-seeding, needed only the cultivation management measures such as planting density and appropriately can obtain cotton yield May.
