Description

The cultural method that Cotton Gossypii is no-tillage summer is live

Technical field

The invention belongs to technical field of cotton culture, it is more particularly to a kind of method being suitable to In Middle And Lower Reaches of Changjiang River Cotton Gossypii low input high-yield culturing in short season, the method is a kind of based on existing cotton variety, based on the no-tillage summer is live, shorten the Cotton Production cycle, realize reducing work and material input, reduce labor intensity, reduce Cotton Production cost, improve cotton planting benefit, eco-friendly cultural method.

Background technology

Cotton Gossypii is to concern the most important fibre crops of people's daily life, thus is also one of worldwide most important industrial crops. Cotton Production occupies very important status in China's national economy, and Cotton cultivated area accounts for the 3% of the whole nation proportion of crop planting gross area, but its output value accounts for the 10% of the crops gross output value. Export goods and earn foreign currency annual 100000000000 dollars with the textile and clothing that cotton fiber is primary raw material, account for that the annual commodity export in the whole nation is earned foreign exchange 1/5. Therefore, Cotton Production is directly connected to the development of China's export-oriented economy, is directly connected to the income of vast cotton growers. Visible, Cotton Production is developing china agricultural production, abundant Chinese people's material life, improve Cotton plantation household economy income, increase China's Foreign Exchange Reserve, expand China's Foreign Trade scale is all made that significant contribution. But, the sustainable development of Cotton Production faces many new challenges.

One is that Cotton Production cycle length, complex management, labour force put into many

Cotton Gossypii has indeterminate growth habit, so the Cotton Production cycle is long.This is one of Cotton Gossypii own growth development characteristics, is also one of major reason of various contradictions generation in Cotton Production. In cotton region, Yangtze River in China basin, Cotton Production is still based on culturing and transplanting seedlings production model, and the general production cycle is 8 months (11 months April), and some areas or peasant household were even up to 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 Gossypii management operation is maximum, management technique is the most complicated. Wherein management operation includes: makes preparation for ploughing and sowing March, do nutritive cube, April seeding and seedling raising, seedbed management, May wholely, fertilising, trench digging, transplant, 5 JIUYUE intertillages, weeding, stubble-cleaning, fertilising, change tune, training, ridging, row's stain, drought resisting, diseases prevention and control (many of which operation also need to repeatedly carry out) such as worms, repeatedly gather, dry in the sun, classification, preserve, tens procedures such as pay 8 November.

Just because of managing, operation is many, management technique is complicated, and therefore labour force puts into many. Cotton Production recruitment 25 30 every mu, is approximately 4 times of Wheat Production recruitment, 3 times of Semen Maydis, 2.5 times of Oryza sativa L., and the Cotton Fields with High Yield recruitment of intensive cultivation is more. Visible Cotton Gossypii is also that in all field crops, the amount of labour used is maximum.

Two is Cotton Production cost increase: labour force's labor cost goes up, and material puts into (pesticide, chemical fertilizer, agricultural film, seed etc.) to be increased, and causes that Cotton Production cost constantly rises, will under cotton planting benefit.

Along with rural laborer shifts to city, rural laborer's labor cost rises steadily. According to investigations, labour force's labor cost of general farming activities in 2013 more than 120 yuan/people/sky, some cotton regions even up to 150 yuan/people/sky or more than; The labor cost of Cotton Gossypii of gathering reaches per kilogram unginned cotton 2.5-3.0 unit.

Cotton Gossypii is also need goods and materials to put into more crop. For 2011, every mu need to put into the materials such as seed, fertilizer, pesticide, regulator, herbicide, agricultural film and add up to 500 600 yuan, and wherein the input of fertilizer accounts for more than 50%. In all fertilizer, amount of application of nitrogen fertilizer is maximum, effect is easiest to be accepted by peasant, cotton grower is also ready most applied nitrogen, but simultaneously in nitrogen application process Problems existing also at most, the most prominent. Therefore, material in Cotton Production puts into, and it is the main aspect of principal contradiction that nitrogenous fertilizer (is used).

Three is that Cotton Production restraining factors are many, and the fluctuation of yield, benefit is bigger

Cotton Gossypii commodity rate, up to 95%, is the field crop that Market Orientation is the highest. Cotton Production is affected by factors: one is that the Cotton Production cycle is long, is affected by disasters such as natural climate, disease pest cause harm, and between the time, output of cotton difference is big; Two is that between plantation peasant household, volume variance is bigger by water and fertilizer condition, management level, input ability restriction; Three be Cotton Production wish by ratio of grain and cotton price and last year price of the cotton affect greatly, cultivated area, plantation wish easily occurred increasing pretty, stagnant subtract, and brings Cotton Production scale to rise and fall indefinite, thus causing yield, price and planting the peak valley of cotton benefit alternately; Four is that cotton price is subject to the impact of the factors of raw cotton import volume and International Petroleum Price and wollen fabrics international trade and impacts bigger.

Additionally, the Chinese countryside quantity of labour force still continues to be deteriorated in constantly minimizing, the structure of labour force single, labor quality further; Meanwhile, agricultural arable area reduces, and prices of the means of agricultural production goes up, labor cost rises, and causes that Cotton Production (comparison) economic benefit glides. On the other hand, the improper input (quantity, method, period) of big quantity of material in Cotton Production, cause that physical waste is general, environmental pressure increases, and widespread pollution from the overuse of fertilizers and pesticides in rural area increases the weight of. Therefore, actively inquire into and save management recruitment, reduce labor intensity, reduce material and puts into, raise labour efficiency, stably increase farmland output, the high-yield high-efficiency cultivation technology that operation is simple, be the effective way of solution the problems referred to above.

Research shows, cotton development stage has plasticity, and it raises with temperature and shortens;Cotton Gossypii biomass accumulation is the basis of yield composition, and its accelerated accumulation phase originates in initial bloom stage; Cotton Gossypii Nutrient uptake is the basis that biomass are formed, and its accelerated accumulation phase originates in initial bloom stage, is slightly before biomass accumulation process; When dose is certain, Cotton Gossypii early stage biological quality and yield negative correlation; When existing kind and cultivation technique, output of cotton depends primarily on unit are and becomes bell number, and unrelated with single-strain bell-forming number; May no-tillage and direct-seeding, as long as the cultivation management measures such as planting density appropriately can obtain cotton yield.

Summary of the invention

It is an object of the invention to overcome the defect of prior art, it is provided that a kind of cultural method being suitable for the no-tillage summer direct-seeding high-yield of Cotton Gossypii, easy to implement the method, easy and simple to handle, reach reduction Cotton Production cost, stable or raising output of cotton, increase and plant cotton benefit, alleviate the effect of environmental pressure.
