Abstract

The invention discloses a preparation method of a 1% lime equivalent type bordeaux mixture, which comprises 1 part of copper sulfate, 1 part of quicklime and 100 parts of water. The method is as below: using two wooden barrels or cylinders; adding 90 parts of water and 1 part of copper sulfate into one barrel or cylinder, and melting the copper sulfate with a small amount of hot water to obtain a copper sulfate solution; adding 1 part of quicklime into the other barrel or cylinder, melting the quicklime with a small amount of water and adding 10 parts of water to obtain lime milk; and cooling the lime milk lower to room temperature, slowly adding the copper sulfate solution into the lime milk while stirring to obtain blue bordeaux mixture.

Description

A kind of preparation method of 1% lime equivalent formula bordeaux mixture

Technical field

The present invention relates to agriculture medication field.

Background technology

Bordeaux mixture is the sky blue liquid that copper-bath and milk of lime mix, and is a kind of protectant, can prevent in germ invaded plants body.Can prevent and treat citrus scab, citrus ulcer, anthracnose of orange, the citrus damping-off of seedling etc.Its concentration has 0.3%, 0.5%, 1% etc., and this can regulate by the consumption of copper sulphate.According to the ratio of copper sulphate and quicklime, be divided into lime half amount formula, lime equivalent formula, that lime is doubly measured formula, the excessive formula of lime etc. is several.

Summary of the invention

The object of this invention is to provide a kind of method of simple preparation 1% lime equivalent formula bordeaux mixture.

Technical scheme of the present invention is: 1% lime equivalent formula bordeaux mixture, use 1 part, copper sulphate, 1 part of quicklime, 100 parts, water (being abbreviated as 1:1:100).When preparation, with two, wooden barrel or cylinder, one discharges water 90 parts, add 1 part, copper sulphate (copper sulphate first dissolves with a small amount of hot water) copper-bath; Another frees 1 part, lime (quicklime is first opened by a small amount of aquation), adds water 10 parts, quicklime breast.Drop to after room temperature until the temperature of milk of lime, by copper-bath, slowly in the milk of lime of falling people, limit bevelling stirs, sapphire bordeaux mixture.

Points for attention when preparation and use: should select the block quicklime of white, the copper sulphate of vivid blue crystallization.The white lime having absorbed water and impure many copper sulphate should not be used.When milk of lime and copper sulfate solution mix, temperature can not exceed room temperature, otherwise easily causes precipitation, affects quality.When preparation, can not use canister, the sprayer that sprayed bordeaux mixture will be cleaned in time, in order to avoid corrosion.Bordeaux mixture can not with soap, resin soap emulsifiable concentrate, the agricultural chemicals such as lime sulfur, oils emulsion and chlorophos mixes and uses.Bordeaux mixture has poisoning to citrus tender shoots, therefore, must before germination, use.Spray after bordeaux mixture, must the 20 days ability in interval use lime sulfur.To use again bordeaux mixture, also obtain 7～10 days, interval, otherwise can cause poisoning.Spray after bordeaux mixture, blister mite easily occurs, must strengthen inspection and the control to blister mite.
