Abstract

The invention discloses an apricot orchard stem and leaf complex herbicide preparation method. The product belongs to the field of herbicide production. The product is prepared through a series of blending processes with the raw materials of 14-16% of glufosinate-ammonium, 2% of sodium dodecylbenzene sulfonate, 52% of water, 10-12% of nitrofen and 20% of ethanol. The production method has the advantages of simple process, low environmental pollution, short reaction time, and mild reaction conditions. The glufosinate-ammonium and nitrofen complex has a synergistic effect. The complex product has good dispersion in water and high activity. The herbicide provides a strong killing effect against growth-stage weeds in apricot orchards.

Description

A kind of preparation method of plantation of almond trees cauline leaf complex weedicide

Technical field:

The invention belongs to weed killer herbicide field, orchard, particularly relate to a kind of preparation method of plantation of almond trees cauline leaf complex weedicide.

Background technology:

Apricot is a kind of excellent fruit tree of China, belongs to rose deciduous tree, general 5 to 7 meters of the apricot height of tree, tree crown is many in the happy type that faces south, and branch is closeer, and blade becomes avette, wealthy avette, blade edge has carefully blunt sawtooth, slightly hair or without hair on blade back, and apricot fruit is circularly claim apricot, apricot strong adaptability, adult apricot bark is thicker, thus can the severe cold of resistance to subzero twenty or thirty degree, the Root System of Apricot is flourishing, bury very dark, approximately suitable with the height of tree, this is its reason resisted cold just also.The seeding row spacing of apricot treelet is about 2-3 rice, the seeding row spacing of Cheng Shu is about 4-5 rice, because the large ventilation and penetrating light of arboretum is good, relatively be applicable to the growth of all kinds of weeds, the weeds of apricot arboretum are of a great variety, existing annual, biennial weeds, also have perennial weed, and principal item has lady's-grass gramineous, green foxtail, eleusine indica, india lovegrass, cogongrass, annual bluegrass, non-irrigated barnyard grass, wild oat, amur foxtail, reed; The argy wormwood, field thistle etc. of composite family, weeds generating capacity is large, fast growth, causes very large threat to apricot growth.The harm of weeds to apricot is mainly manifested in: 1. weeds and apricot fight for water, fertilizer; 2. weeds be spread disease, the medium of insect pest or host; 3. some weeds to people and livestock poisonous.Use the method for weed killer herbicide to have two kinds, one is weeding before bud, and another kind is cauline leaf spraying in vegetative period.The present invention is the composite weed sprays agent of cauline leaf that a kind of weeds being in vegetative period to plantation of almond trees use, and this product is made by a series of blending technique for raw material with careless ammonium phosphine, nitrofen, organic solvent, surfactant, water.Grass ammonium phosphine, as a kind of novel contact killing type steriland herbicide, compared with traditional steriland herbicide glyphosate, has the following advantages: (1) herbicide speed is fast; (2) good to crop safety; (3) can the orchard that exposes of or root system shallow for crop root safely; (4) for killing the axillalry bud and side shoot that remove and fruit tree bottom bark from old tress of growing up grows, to dry branch safety; (5) effectively can kill glyphosate and be difficult to kill the drug resistance and Herbicide-resistant weeds (as eleusine indica, kitchen garden, Horseweed Herb) removed; Nitrofen can wipe out and treat insect pests and plant diseases annual weed, inhibitory action is played to perennial weed, all there is good killing effect to the seed plumule of annual weed, young shoot, seedling, barnyard grass, kitchen garden, lady's-grass grass, convexutricle sedge herb, grey dish, wild amaranth, knotweed, alkali grass, fescue, Monochoria vaginalis, Drilgrass, green foxtail etc. can be prevented and kill off.Grass ammonium phosphine, nitrofen is composite synergistic effect, and compound product is good dispersion in water, active high, powerful to the weeds killing action being in vegetative period in apricot field.

Summary of the invention

The problem that the present invention mainly solves is to provide a kind of preparation method of plantation of almond trees cauline leaf complex weedicide, and the raw material weight proportioning of producing the use of this product is: careless ammonium phosphine 14-16%, neopelex 2%, water 52%, nitrofen 10-12%, ethanol 20%.

The present invention can be achieved through the following technical solutions:

A preparation method for plantation of almond trees cauline leaf complex weedicide, is characterized in that being made up of following steps:

(1) first added by the water of formula ratio in the first agitator tank, start under normal temperature to stir, the rotating speed of agitator is 25-30 rev/min, adds careless ammonium phosphine, the neopelex of formula ratio while stirring successively, stirs 0.3-0.5 little of whole dissolving.

(2) first added by the ethanol of formula ratio in the second agitator tank, start under normal temperature to stir, the rotating speed of agitator is 20-25 rev/min, adds the nitrofen of formula ratio while stirring, is stirred to nitrofen and all dissolves.

(3) aqueous solution of careless ammonium phosphine, neopelex is sent into high-speed shearing machine, the rotating speed that normal temperature lowers high-speed shearing machine is 210-220 rev/min, slowly the mixture of nitrofen and ethanol is sent into high-speed shearing machine, after cleavage reaction 0.2-0.3 hour, obtain finished product.

Further technical scheme of the present invention is:

The purity of the careless ammonium phosphine described in step (1) is 95%.

The purity of the nitrofen described in step (2) is 90%.

The stirring reaction time described in step (1) is 0.35 hour;

The high speed shear reaction time described in step (3) is 0.25 hour.

Step (1), step (2), normal temperature described in step (3) are 5-35 DEG C.

The invention has the beneficial effects as follows: the preparation method providing a kind of plantation of almond trees cauline leaf complex weedicide, the method tool has the following advantages: technique is simple, environmental pollution is little, reaction time is short, reaction condition is gentle, and careless ammonium phosphine, nitrofen is composite synergistic effect, and compound product is good dispersion in water, active high, powerful to the weeds killing action being in vegetative period in apricot field.
