Abstract
The present invention provides a kind of cotton and sprays the operational method for improving leaf landing rate after defoliation ripening medicament.Compared with prior art, the present invention selects electronic single rotor plant protection drone to promote to fall the equipment of operation as development cotton leaf wind-force after cotton defoliation ripening, with stable and powerful pushing wind field when its flight operation, " marcescence " and the cotton leaf of " falling and hanging branch " after defoliation ripening medicament can will be sprayed effectively to blow off plant, it effectively compensates for existing operational method and only focuses on defoliation ripening medicament and spray but to cotton leaf " marcescence " after spray, the deficiency of " falling and hanging branch " problem shortage reply means, it is organically combined to which defoliation ripening medicament " Chemical defoliation " and unmanned plane are pushed wind " physics blows leaf " two kinds of technological means, effectively increase the practical disleave rate of cotton and landing rate, and then reduce subsequent machine pick cotton percentage of impurity, with operating efficiency height, operation effectiveness is good and the advantages such as operating cost does not obviously increase , should be widely promoted.
Description
Technical field
The present invention relates to a kind of by two kinds of operation means phases of " defoliation ripening agent Chemical defoliation " and " push scenery reason and blow leaf "
In conjunction with to improve the operational method of cotton defoliation rate and landing rate.More particularly, refer to that a kind of cotton sprays defoliation ripening
The operational method of leaf landing rate is improved after medicament.
Background technique
Cotton is to Later growth, and leaf, which starts to dry up, to fall off, and cotton boll graduallys mature blow-of-cottons.Nowadays, it is adopted to be easy to use
Cotton machine carries out mechanization cotton picking and reduces percentage of impurity, needs to spray defoliation ripening agent to cotton before machine pick cotton.Defoliant is such as
Magron, the treasured that falls off etc. are sprayed onto penetrate into blade on cotton leaf after, absorb the moisture in blade so that leaves water loss, withered,
Petiole attachment region forms dialysis layer, and cotton leaf is made to fall off；Ripener such as ethephon (CEPHA),2-(chloroethyl) phosphonic acid etc. has reduction boll endoperoxides object enzymatic activity
Effect, spray to balance between the ethylene and auxin after ethephon (CEPHA),2-(chloroethyl) phosphonic acid in cotton boll and change, cotton boll is promoted to crack.Currently, spraying machine
Airplane spray can be used for tool and overhead spraying machine sprays.
Found during actual job, after spraying defoliation ripening agent to cotton, there is cotton leaf " it is withered without
Fall " and " falling and hanging branch " phenomenon." marcescence " refers to that leaf is withered after drug effect plays a role, but petiole not with plant reality
Now efficiently separate；" falling and hanging branch " refers to that the withered rear petiole of leaf is realized with plant and efficiently separates, but fallen leaves are then hung over
On cotton plant branch.Cotton leaf " marcescence " and " falling and hanging branch " phenomenon not only significantly reduce cotton defoliation ripening operation
Cotton-wool percentage of impurity is reduced during quality, more back machine pick cotton, raising machine pick cotton quality brings very big negative effect.Cause
This, needs to develop a kind of operational method that can be reduced leaf hanging branch after cotton sprays defoliation ripening, promote leaf landing.
Summary of the invention
The object of the present invention is to provide the operators that a kind of cotton sprays raising leaf landing rate after defoliation ripening medicament
Method, to solve the above technical problems.By defoliation ripening medicament " Chemical defoliation ", " physics is blown the operational method with unmanned plane pushing wind
Two kinds of operation means of leaf " organically combine, and can effectively improve cotton defoliation rate and landing rate, and then reduce machine pick cotton percentage of impurity.
