Description

A kind of method, defoliant and its application of hemp disleave
Technical field
The present invention relates to defoliant field, in particular to a kind of method, defoliant and its application of hemp disleave.
Background technology
Hemp, Classification system are Cannaabis Salival, and popular name is Chinese fiber crops, cold fiber crops, hemp, the male plant of hemp etc., and English is entitled Hemp, true hemp or common hemp, belong to Cannabaceae Cannabis annual herb crop.Big straw is high 1~5 meter, its Stem heart wood, one layer of bast is around wrapped in, contains many fibers, leaf palmation, by 5~11 decomposite leaf groups in it Into zigzag decomposite leaf about 50mm~150mm is long, 10mm~20mm is wide.Hemp can be used as weave linen, make fishing net, Rope, linen thread, seat through etc., and manufacture Modern cigarette industry the paper even preferred raw materials of money etc..
Since modern age, due to containing THC (THC) in hemp, it has been largely used to manufacture excitant and drugs, it is more Number western countries prohibite plantation hemp, and the yield of hemp declines year by year, and the application study of hemp also tends to standstill state.But The emergence again of natural fiber since with last century the nineties, hemp have the advantages of many notable, including：Hemp grows Adaptability is extremely strong, no disease and pests harm, and hemp is resistance to macerate sun-proof, Anti-moth-eating, and absorption gas permeability is strong, antistatic, antiultraviolet and suppression The performance of bacterium is strong, meanwhile, low THC Hemp Varieties seed selection success, therefore, plantation ban of the various countries to hemp releases one after another therewith, China is the production country of maximum fiber hemp at present.With the increasingly increase of hemp demand, the plantation to hemp adds The improvement of work method has important economic results in society.
And a great problem of the hemp in process is planted is, due to remaining green when it is due to become yellow and ripe, when hemp reaches the harvest season, leaf Piece is still less to come off.On the one hand, the presence of blade causes the difficulty of mechanical harvest, and on the other hand, blade can also extend waste of flax Shine dry spell, the dip time of stalk, can also make raw jute quality decline.Therefore, big anesthesia stem is before impregnation, it is necessary to artificial Or mechanical disleave, waste time and energy, or, chloric acid magnesium solution is sprayed before hemp harvests, realizes the Chemical defoliation of hemp.And chloric acid The dosage of magnesium big (per hectare needs to use 60% 28 kilograms of magron), toxicity are also larger, and use is not convenient enough.
Modern society is to the economy and environmental requirement more and more higher of defoliant, especially in the side such as effect, residual, toxicity Face.Therefore, this area need badly exploitation defoliation effect it is good, it is less toxic, to hemp quality damage small and economical and practical hemp take off Leaf agent and corresponding hemp disleave method.
In view of this, it is special to propose the present invention.
The content of the invention
The first object of the present invention is to provide a kind of method of hemp disleave, methods described using the chloro- 4- ethylamino-s of 2-- 6- isopropylamine bases -1,3,5-triazines to maturity period hemp carry out disleave, have efficiently, low toxicity, do not damage hemp quality and The advantages of dosage is few economical and practical.
The second object of the present invention is to provide a kind of method of hemp disleave, methods described using the chloro- 4- ethylamino-s of 2-- The composition of 6- isopropylamine bases -1,3,5-triazines and other defoliants carries out disleave to maturity period hemp, has and imitates, be less toxic, no The advantages of damaging hemp quality and few economical and practical dosage.
The third object of the present invention is to provide a kind of defoliant, the defoliant have efficiently, low toxicity, do not damage hemp The advantages of fiber quality and few economical and practical dosage.
For the fourth object of the present invention in providing application of the above-mentioned defoliant in hemp disleave, the application has disleave Efficiency high, low toxicity, the advantages of hemp quality and dosage are few economical and practical is not damaged.
In order to realize the above-mentioned purpose of the present invention, spy uses following technical scheme：
A kind of method of hemp disleave, before methods described is included in hemp harvest, using the chloro- 4- ethylamino-s -6- isopropyls of 2- Amido -1,3,5-triazines, the amount of application of the chloro- 4- ethylamino-s -6- isopropylamine bases -1,3,5-triazines of 2- is 20~450g activity Material/mu, it is preferable that 90g active materials/mu.
A kind of method of hemp disleave, before methods described is included in hemp harvest, using the chloro- 4- ethylamino-s -6- isopropyls of 2- Amido -1,3,5-triazines and other defoliants, the amount of application of the chloro- 4- ethylamino-s -6- isopropylamine bases -1,3,5-triazines of 2- are 20~450g active materials/mu, the amount of application of other defoliants is 3~80g active materials/mu.
A kind of defoliant, the defoliant includes the chloro- 4- ethylamino-s -6- isopropylamine bases -1,3,5-triazines of 2- and other are de- Leaf agent, wherein, the mass ratioes of the chloro- 4- ethylamino-s -6- isopropylamine bases -1,3,5-triazines of 2- and other defoliants for 20~ 450:3~80.

The disleave rate of the hemp after embodiment 1~8 and the processing of the methods described of comparative example 1~6 and dead numb rate are detected, specifically Testing result is referring to table 1.It can be seen from result shown in table 1, using the chloro- 4- ethylamino-s -6- isopropylamine bases -1,3,5-triazines of 2- and The combination of itself and other defoliants can effectively make hemp disleave, while not influence the fiber quality of big anesthesia stem.It is and independent The effective disleave of hemp can not then be made using other defoliants, although or can make hemp disleave, dead numb rate is high, has a strong impact on The quality of hemp.
The disleave rate of the hemp of table 1 and dead numb rate
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent The present invention is described in detail with reference to foregoing embodiments for pipe, but it will be understood by those within the art that：Its The technical scheme described in foregoing embodiments can still be modified, either to which part or all technical characteristic Carry out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention skill The scope of art scheme.
