Description
Technical field
The invention belongs to technical field of pesticide, and in particular to a kind of cotton defoliant.
Background technology
Cotton was once the important strategic materials in China, was held the balance in agricultural economy general layout.Cotton in China production occupies generation
Boundary forefront, it is weave big country and maximum cotton country of consumption, there are 23 provinces, municipalities and autonomous regions production cottons in the whole nation, and Cotton Industry exists
Occupy critical role in national economy.
Because of the indeterminate growth habit of cotton and the limitation of weather conditions, in particular with the development of Summer cotton, in China
Most of cotton region, when withered frost arrives, always there are many cotton bolls to have little time blow-of-cottons, a part of late autumn peach therein at all can not be into
It is ripe, other can ripe cotton boll reluctantly, also turn into flower after frost.Flower quality is very poor after frost, and use value is very low.Many
Area, the evening of cotton receive the sowing, seedling growth and the yield that directly affect rear stubble wheat again.Harvesting is the important ring in Cotton Production
Section, but the blade remained on cotton plant, not only influence harvesting speed（Especially mechanical harvesting）, and have an effect on the product of cotton
Level.Therefore, cotton is accelerated the ripening in good time and disleave, high yield high-quality to cotton and reaped a bumper harvest of grain and cotton all significant.
The cotton ripener being commonly used is ethephon (CEPHA),2-(chloroethyl) phosphonic acid.Ethephon (CEPHA),2-(chloroethyl) phosphonic acid is a kind of ethylene evolution agent, can be divided in vivo
Solution, discharges ethene.Ethene promotes fruit maturation, also effective to cotton.Cotton bell is typical climacteric type fruit, positive reason
Cotton boll produces ethene always under condition, before being ftractureed to the stage of ripeness, ethylene evolution peak occurs, promotes with cracking blow-of-cottons to have in cotton boll
The a series of complex physiological reaction of pass.Because temperature limits, the Boll Development of late origin is slow or stagnates, and oneself can not discharge
Enough ethene reaches physiological maturity.Ethephon (CEPHA),2-(chloroethyl) phosphonic acid manually is used, the deficiency of ethene in cotton boll can be supplemented, promotes ripe and tells
Wadding.The mechanism of action that ethephon (CEPHA),2-(chloroethyl) phosphonic acid accelerates the ripening is the content for improving ethene in cotton boll, accelerates the development of cotton boll, necessarily goes out before making cracking
Existing ethylene evolution peak, which advances to, to be come, so as to improve cracking blow-of-cottons.Experiment shows, can be shifted to an earlier date using ethephon (CEPHA),2-(chloroethyl) phosphonic acid in good time, in right amount
Cotton boll blowing peak, frost before flower yield increase 25-50%, fiber quality improve, and can early suddenly with multiple cropping vernal crop diversity.Second
Alkene profit has good effect of accelerating the ripening to cotton, but defoliation effect is not as good as effect of accelerating the ripening.
The cotton defoliant being commonly used is mainly Thidiazuron.Thidiazuron is a kind of the new of tool cytokine activity
Type efficient plant growth regulator, crop photosynthesis can be promoted, improve crop yield, improve fruit quality, enhancing fruit is resistance to
Storage property.Make defoliant use on cotton planting, after being absorbed by plant, the chorista natural shape between petiole and stem can be promoted
Into and come off.Thidiazuron does not injure blade directly, promotes the generation of ethene, suppresses the transport of auxin, reduces auxin and second
The ratio of alkene.24h after Thidiazuron processing, the ethene of blade release reach peak value, are maintained at certain level until blade
Come off.
When cotton boll cracking 70% or so, every mu of Thidiazuron wettable powder 100g of use 50%, complete stool spraying is watered, is opened within 10 days
Begin fallen leaves, blow-of-cottons increase, peaks within 15 days, has declined within 20 days.Cotton leaf tear-away 90% or so, to plant fanout free region, blow-of-cottons
Normally.But it is there is also shortcoming, such as：Thidiazuron work it is slow, it is especially true at low temperature, thus day samming when being less than 21 DEG C not
It is recommended that use.In all harvest adjuvants, the time without rain is most long after Thidiazuron requires spray（24h）, illustrate its absorb compared with
Slowly.
The content of the invention
For insufficient existing for above-mentioned technology, the present invention provides a kind of cotton defoliant, before disleave is good, maturity is good
Put, can not only greatly improve the efficiency of machine pick cotton, meanwhile, content is considered to be worth doing to the leaf for reducing machine pick cotton flower, improves the product of cotton
Matter, reduce link of clearing up and processing etc. and play vital effect.
To achieve these goals, the present invention provides following technical scheme：
A kind of cotton defoliant, it is characterised in that：Including tebuthiuron, magron；The quality of the tebuthiuron and the magron
