Abstract
The invention relates to a growth regulator of a combination cotton of thidiazuron and ethephon, which is characterized by comprising the following components according to weight percentage: 45 to 90 percent of active ingredients of the thidiazuron and the ethephon and residual addition agent, wherein, the weight ratio of the thidiazuron and the ethephon is 1:2.5 to 5. The invention adopts osmotic agent of the addition agent, solid carrier, wetting agent and dispersant, etc. commonly used in the agricultural chemical field to be made into wetting powder formulation, the formulation can be used as plant growth regulator for the ripening and defoliation of cotton. The growth regulator of the invention has the advantages of good effects on the defoliation and ripening of cotton, improving the grade of cotton, increasing the output of cotton, especially the output before frost and improving the benefits of farmers.
Description
Technical field
The present invention relates to a kind of vegetable lamb growth regulator composition, it relates to the plant growth regulator that flower makes cotton defoliation and accelerates the ripening before gathering in the crops before the cotton frost.Belong to the plant growth regulator technical field.
Background technology
Cotton is the most widely used textile fiber, and it all has plantation in the most of area of China, as economic crops, has very important effect in national economy.Cotton has unlimited flowering habit, and tie bell from beginning to bloom long to the knot bell end required time of blooming, and needs about 50-70 days to the cotton boll blow-of-cottons from blooming, and therefore, the cotton boll bell phase on the same cotton plant differs greatly.Because reasons such as weather (particularly northern cotton region) or culture techniques, often there are some cotton bolls can not normal mature before falling frost, spend or do not open bell and become the frost back, thereby influence output and the grade of cotton.Under the normal condition, before withered frost season, because climatic variation, temperature reduces, the cotton knot bell that will stop substantially blooming, and this moment, the blow-of-cottons rate of cotton was approximately 80%, and the natural disleave rate of blade is approximately 50-70%.Gathering is important step in the Cotton Production, but remains in the blade on the cotton plant, the influence speed (especially mechanical harvesting) of gathering not only, but also influence the grade of cotton., for the output that improves flower before the frost and improve cotton grade, at the cotton late growth stage, cotton is accelerated the ripening and disleave is handled and is very important, also be one of important step of cotton management in good time for this reason.
The cotton ripener that generally uses is ethrel and ethrel paraquat aqua at present.Ethrel (ethephon), chemical name is: the acid (have another name called one examination spirit) of seeing of 2-chloroethyl, soluble in water, methyl alcohol, ethanol are insoluble in benzene and dichloroethylene.Ethrel is very stable in the highly acid medium, but decomposite ethene very soon in greater than 4 medium at pH value, the pH value of the general plant cell liquor of cause is greater than 4, so ethrel enters in the plant corpus through blade, (bark) epidermis, the fruits and seeds of plant, conduct to site of action then, just discharge ethene, play dematuration.Test shows, sprays ethrel in good time, in right amount and can make the cotton boll blow-of-cottons in advance and concentrate, and the flower ratio can reach about 90% before the frost.Administration time is generally grasped about the cotton boll blow-of-cottons 40%-50% of field, and daily maximum temperature is more than 20 ℃, and preceding 3 week-4 of local withered frost are about week.Sprayed behind the ethephon agent 5-7 days, the blow-of-cottons effect is still not obvious.After the medication 10 days, the blow-of-cottons cotton boll obviously increased, and during by 15 days, cotton boll blow-of-cottons rate can reach about 80%, and after the medication about 30 days (before the withered frost), the blow-of-cottons rate reaches about 90%.Ethrel paraquat aqua (CN1233397A) is better than the agent of ethrel list to the effect of accelerating the ripening of cotton, can improve the output of cotton simultaneously, but can not effectively carry out disleave to cotton.
The cotton defoliant that generally uses is based on Thidiazuron at present.Thidiazuron (thidiazuron) has another name called the treasured that comes off, chemical name: 1-phenyl-3 (1,2,3 ,-thiadiazoles-5-yl) urea, belong to the heteroaromatic ureas, be a kind of compound, on cotton, make defoliant and use, can be promoted to form absciss layer between petiole and the stem after the plant absorbing with the effect of special plant growth regulating, blade is come off ahead of time, gather efficient and improve cotton grade thereby improve.Cotton growth middle and later periods (generally reaching the medication of the 40%-50% left and right sides), cotton plant is sprayed in cotton boll blow-of-cottons rate.Behind the medicine 5 days, it is dim that the cotton leaf look shows slightly, and it is withered that blade edge begins chlorisis, but it is less to come off; 10 days disleave rates obviously increase behind the medicine; 20 days disleave rates reach about 85% behind the medicine; Behind the medicine 30 days the time disleave rate reach about 90%, different year, different cotton fields defoliation effect has certain difference.
There is not a plant growth regulators can well promote the cotton maturation can effectively promote cotton defoliation again at present, in production reality, people mainly use ethrel and ethrel paraquat aqua to carry out cotton and accelerate the ripening, use ethephon agent slower to the effect of accelerating the ripening of cotton, use ethrel paraquat aqua can improve the effect of accelerating the ripening, but two kinds of medicaments can not effectively carry out disleave to cotton, influence the speed of gathering, and cause the reduction of cotton grade; Use Thidiazuron to promote cotton defoliation, help improving the mechanization speed of gathering, but can not effectively improve the ratio of flower before the frost.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming,, obtain in the hope of a dispenser cotton is accelerated the ripening and the disleave double effects cotton defoliant Thidiazuron and the composite by a certain percentage Thidiazuron ethrel composition of making of ripener ethrel adding assistant.
Technical scheme of the present invention is achieved in that the composite cotton growth regulator of this Thidiazuron ethrel, it is characterized in that conditioning agent comprises following percentage by weight: 45-90% Thidiazuron and ethrel active ingredient and auxiliary agent surplus; Wherein Thidiazuron and the weight ratio of ethrel active ingredient in conditioning agent are 1: 2.5-5.
The composite cotton growth regulator of described Thidiazuron ethrel, Thidiazuron and the weight ratio of ethrel active ingredient in conditioning agent are 1: 4.
The composite cotton growth regulator of described Thidiazuron ethrel, its application form is a wetting powder, auxiliary agent comprises 1-2% wetting agent, 0.5-3% dispersant, 0.5-3% bleeding agent and solid carrier surplus.
