Abstract

The invention provides a high-efficiency defoliating and ripening agent used before picking cotton. The high-efficiency defoliating and ripening agent is prepared by the following steps of: fully stirring 250 to 850 kilograms of ethrel, 55 to 200 kilograms of thidiazuron, 0.50 to 1.90 kilograms of DT34 auxiliary agent and 0.15 to 0.60 kilograms of DM12 auxiliary agent in a reaction kettle in turn; fully dissolving 15 to 53 kilograms of water and 0.18 to 0.22 kilograms of silicone antifoaming agent in advance to obtain solution; adding the solution; and stirring for 25 to 30 minutes at normal temperature and normal pressure to obtain a finished product. The defoliating and ripening agent is sprayed in an application dosage of 80 to 120ml/mu when the cotton fiber grow rate is over 60 to 70 percent before picking the cotton. The defoliating and ripening agent is sprayed at 6 to 8 pm in September to October of the maturation period of the cotton; rainy days are avoided; and the defoliating and ripening agent can be re-sprayed if the defoliating and ripening agent is caught in the rain. The product combines the efficiencies of ripening and defoliating, saves labor, time and effort, greatly improves labor production efficiency and cotton quality rate, and lays a solid foundation for manual fast harvest and mechanical one-time harvest. Compared with a conventional single product, the picking period is 15 to 20 days earlier and the average defoliation rate is over 90 percent.

Description

A kind of efficient defoliation ripening agent that is used for before the cotton picking

Technical field

The present invention relates to the ripe of cotton and pluck, especially not only the disleave but also the technology of accelerating the ripening used this agent effectively to solve because disleave is not agile, influences the drawback of cotton picking quality, reaching the effect of the raising output that reduces cost.

Background technology

The research that discloses domestic relevant cotton defoliation ripening agent according to literature search has: 1. Hebei province's grain is made the Wang Gui of institute and the people such as is opened and invented the composite cotton growth regulator of a kind of Thidiazuron ethrel (number of patent application: 200810054702.2), comprise following components in weight percentage: 45%～90% Thidiazuron and ethrel (weight ratio is 1: 2.5～5) active ingredient, surplus is auxiliary agent (agricultural chemicals bleeding agent, solid carrier, wetting agent, a dispersant etc.), can be used for accelerating the ripening and disleave of cotton.2. cotton defoliant (number of patent application: 200810079653.8), ooze spreader-sticker etc. by 40% ethrel, oxine, chlorate and height and mix has been invented by Shanxi Zhenyuan Biological Technology Co., Ltd..3. Wang Xu the people such as levies and has invented cotton defoliation ripening multicomponent preparations and preparation method thereof (number of patent application: 200710115227), by defoliant: titanium preparation: weed killer herbicide: auxiliary agent=10～250: 20～600: 10～100: 5～50 raw materials in weight portion are made.Preparation method: earlier auxiliary agent is added in the defoliant, add the titanium preparation again, add weed killer herbicide then, stir while adding, pulverize by the cell grade atomizer at last, get the emulsion liquid product.4. Xinjiang Greenland Science and Technology Development Ltd has invented a kind of cotton defoliant (wetting powder, number of patent application: 0315277), it has consisted of (percetage by weight): paclobutrazol 52～54, grand 23～25,885 pesticide synergistic agents 23～25 of plug benzene.The disleave rate is more than 80% after 20 days when it is sprayed onto cotton plant, and cotton boll accelerates the ripening rate more than 30%.Paper publishing has: 5. Ma Yan of The Chinese Academy of Agriculture Science and Technologys Cotton Research Institute etc. deliver " effect of several defoliation ripening agent on the cotton paper of studying Chinese cotton has disclosed, reach at 25%～30% o'clock in cotton boll blow-of-cottons rate, spray to take off and tell grand, Thidiazuron, 3 kinds of defoliation ripening agent of ethrel, the result shows, take off to tell to swell and mix use with ethrel (36.5ghm^-2+600ghm^-2), have higher defoliation effect and dematuration preferably, 10～20d drug effect reaches 86.95%～95.03% behind the medicine, and the blow-of-cottons drug effect reaches 7.08%～11.24%; Use the defoliation effect of Thidiazuron 225ghm^-2 more obvious, 10～20d drug effect reaches 88.09%～97.73% behind the medicine, is significantly higher than ethrel 600ghm^-2 and 720ghm^-2 and handles, and effect is lower than ethrel but it accelerates the ripening.

Preparing and synthetic efficient defoliation ripening agent of the present invention's design by ethrel, Thidiazuron, DT34 auxiliary agent, DM12 auxiliary agent, silicone defoaming agent and water; the disleave effect of will accelerating the ripening unification; the technique effect that produces is very remarkable; will produce far-reaching influence to the plantation of scale cotton, great more practical value is arranged.

Summary of the invention

The objective of the invention is to: the efficient defoliation ripening agent that provides, the disleave effect of will accelerating the ripening unification is compared with the single product of routine, and the picking period shifts to an earlier date 15-20 days, can increase production more than 15%.

The object of the present invention is achieved like this: a kind of efficient defoliation ripening agent that is used for before the cotton picking, form by ethrel, Thidiazuron, DT34 auxiliary agent, DM12 auxiliary agent, silicone defoaming agent and water; Spray the effect that reaches volume increase through in good time, its step is as follows:

Preparation: ethrel 250-850 kilogram, Thidiazuron 55-200 kilogram, DT34 auxiliary agent 0.50-1.90 kilogram, DM12 auxiliary agent 0.15-0.60 kilogram place reactor fully to stir successively; With the fully dissolving in advance of water 15-53 kilogram, silicone defoaming agent 0.18-0.22 kilogram, add, normal temperature and pressure stirred 25-30 minute down, promptly got this finished product again;

Spray: before cotton picking, go out the wadding rate more than 60-70%, formulation rate is a 80-120ml/ mu.

Described defoliation ripening agent, medicament spray 9-10 into the maturing stage of cotton between the month, and evening on the same day is during 6-8; Take shelter from rain, chance rain is resprayed to execute and is got final product.

Described defoliation ripening agent, medicament spray adopts mechanically actuated or manual operations, can make the picking period shift to an earlier date 15-20 days, and average disleave rate is more than 90%.

Described defoliation ripening agent is prepared selected reagent and is the commercially available prod.

The present invention design is from production practices, and the scientific research personnel is according to growth rhythm and the characteristics of cotton, the defoliation ripening of development volume increase agent, unfavorable factor such as that the cotton of can effectively avoid low because of temperature, adverse weather causing is remaining green when it is due to become yellow and ripe is late-maturing, blow-of-cottons slow, the blow-of-cottons rate is low; Because product has stronger interior suction conduction; conducted to cotton plant and each position rapidly by cotton leaf absorption; abscisic acid and ethene is synthetic in the inductor; promote that fast accelerating the ripening between the petiole comes off; do not press from both sides shell, do not hang wadding, not fallen flowers, promote ripe; can increase fiber, improve ginning outturn, adapt to mechanical picking especially, very suitable to the cotton producing region of scale.

This product sprayed 5-7 days, and blade comes off with petiole integral body under dark green state, peaked in 7-15 days, and average disleave rate is more than 90%; Can effectively reduce cotton, the shoddy cotton in frost back, effect of increasing production is very remarkable.

To the accelerate the ripening disleave effect unification of this product is compared with the single product of routine, the saving of labor, save time, laborsaving, improved the labor productivity and the cotton factor of merit greatly, for manually gathering fast and disposable the gathering of machinery taken a firm foundation, show technological progress.
