The calcium cyanamide oil suspension can greatly improve the wetting and spreading performance on fruit branches and permeating performance on branches of calcium cyanamide, improves rainfall erosion resistance, overcomes the shortcomings of fertilizer damage caused by nonuniform coating, low use work efficiency and the like of the original method, prolongs the retention time of the effective ingredients on the branches, reduces the consumption of calcium cyanamide, reduces dust pollution, greatly improves use effect of calcium cyanamide and is convenient for transportation and application. The calcium cyanamide oil suspension can be applied to a dormancy breaking agent of grape, apple, pear, peach cherry and other fruit trees.
Description
Technical field
The invention belongs to the agricultural chemicals field, is a kind of calcium cyanamide oil suspension specifically, and it is used for the chemicals for breaking dormancy of the gardening plant such as grape.
Background technology
The calcium cyanamide chemical name is nitrolim, molecular formula CaCN
2, molecular weight 80.09 at high temperature makes with the nitrogen treatment calcium carbide powder.Industrial mainly for the production of two cyanogen ammoniums, potassium ferrocyanide, guanidine and thiocarbamide; Except using as nitrogenous fertilizer, also having the effects such as the soil acidity of improvement on agricultural, is a kind of important Organic Chemicals.
In Grape Dormancy, growth inhibitory substance is abscisic acid (ABA), the abscisic acid (ABA) of degrading of low temperature below 7.2 ℃, and grape reaches required low temperature amount, and the winter buds dormancy problem just can solve.With the female branch of calcium cyanamide result, the effect of promotion abscisic acid (ABA) degraded is arranged, can replace to a certain extent the biological effect of low temperature, therefore calcium cyanamide is called chemicals for breaking dormancy.
Calcium cyanamide operation technique concentration: calcium cyanamide 15%～20%, namely to 5～7 times, water, the weak kind concentration of growing way should be hanged down, and surpasses 20% and easily causes fertilizer damage, sprouting inhibitor on the contrary.Cyanogen ammonia is calculated as 1.5% by active ingredient.
Operating period: the south operating period should rest in rudiment front 20～35 days.The north operating period should rest in rudiment front 10～20 days.Should not use too early, otherwise too early rudiment, as cold late spring, increase frost damage prevention in early spring, damage to plants caused by sudden drop in temperature difficulty, also should not cross slow use.
Calcium cyanamide also is used for the chemicals for breaking dormancy of the fruit trees such as apple, pear tree, peach.
At present method commonly used is: calcium cyanamide is slowly poured into more than 70 ℃ in hot water, stirs immediately, and container is added a cover, and soaks and can use after naturally cooling more than 2 hours, should not use cold water soak.Be coated with a position: bearing basal shoot 1～2, top bud can not be coated with (apical dominance), and all the other buds connect branch and are coated with together.Note old climing should not being coated with, the first year, bearing-age tree did not utilize this part of hibernaculum of fruit bearing shoot not to be coated with.Be coated with a method: with little brush, liquid is coated on twig, stirs water liquid while being coated with, black precipitate is coated on bearing basal shoot together, be coated with black can the identification of branches and tendrils, avoid recoat or holiday.With joining with being coated with, soaked with liquid can be coated with after 2 hours, or immersion second day overnight is coated with.
The method of using at present is very backward, because calcium cyanamide is slightly soluble in water, the calcium cyanamide solution allocation time is long, the calcium cyanamide particle is large, suspensibility is low in water, moistening spread poor performance, consumption are greatly on fruit branch, resistance of rainwater washing against, crawling easily do not produce fertilizer damage, use the shortcomings such as work efficiency is low.
Summary of the invention
The objective of the invention is provides a kind of calcium cyanamide oil suspension for overcoming above-mentioned the deficiencies in the prior art.
For achieving the above object, the present invention adopts following technical proposals:
A kind of calcium cyanamide oil suspension, its formula comprises the material of following mass percent: calcium cyanamide 5%-30%, Ricinate 1%-5%, structure regulator 1%-2.5%, stabilizing agent 0.5%-2%, vegetable oil or mineral oil are supplemented to 100%.
Described Ricinate is the formaldehyde condensation products MF of addition product, lignosulfonates polymer NNO, benzyl naphthalene sulfonic formaldehyde condensation compound CNF, the methyl naphthalene sulfonic acid sodium of castor oil polyoxyethylene ether BY series, fatty acid oxirane, one or more the mixture in polycarboxylate polymer styrene acrylic copolymer MOTAS.
Described castor oil polyoxyethylene ether BY series is EL-10, EL-20, EL-30, EL-40, EL-60, EL-80, EL-90, BY-110, BY-120, BY-130, BY-140 or BY-201 for model.
The addition product of described fatty acid oxirane is one or more mixtures in polyoxyethylene oleic acid ester, polyoxyethylene stearic acid ester, rosin acid polyoxyethylene ester, alkylphenol polyoxyethylene phosphate.
Described structure regulator is one or more the mixture in organobentonite, xanthans, carboxymethyl cellulose, marine alga saccharic acid, carragheen, pectin, guar gum.
Described stabilizing agent is one or more the combination in 2,6-di-tert-butyl-4-methy phenol, epoxidized soybean oil, epoxy linseed oil, pentaerythrite etc.
Described vegetable oil or mineral oil are one or more the mixture in methyl oleate, peanut oil, soybean oil, palm oil, cottonseed oil, agricultural diesel oil.
The calcium cyanamide oil suspension comprises and adds on this basis second active ingredient, as macroelement fertilizer, secondary nutrients, trace element fertilizer etc.Second active ingredient can adopt commercially available composite fertilizer, and prepares as required, and consumption is 0-50%.
The present invention is with calcium cyanamide, Ricinate, structure regulator, stabilizing agent, after vegetable oil or mineral oil proportionally mix, becomes the calcium cyanamide oil suspension by the grinding of the equipment such as agitator, homogenizer, sand mill, homogenizing.
This calcium cyanamide oil suspension using method: the south operating period should rest in rudiment front 20～35 days.The north operating period should rest in rudiment front 10～20 days, diluted as required 2-50 doubly, and branches of fruit trees spraying or brushing are used.
The invention has the beneficial effects as follows increase substantially calcium cyanamide in moistening spread performance and the permeance property on branch on fruit branch, improve the resistance of rainwater washing against ability, overcome original method crawling and easily produce fertilizer damage, use the shortcomings such as work efficiency is low, extend the retention time of active ingredient on branch, reduce the consumption of calcium cyanamide, reduce dust pollution, be convenient to transportation and use, significantly improve the result of use of calcium cyanamide, can be applicable to the chemicals for breaking dormancy of the fruit trees such as grape, apple, pears, peach, cherry.
