Abstract

The invention relates to the formulation of seed pelletization and dressing agent containing rare earth elements and the preparing process, wherein the agent is prepared from Attapulgite (Mg5Si8O20(HO)2(OH2)*4H2O as the main constituent), talcum powder, mixed nitric rare earth, potassium nitrate, monobasic potassium phosphate, boracic acid, zinc sulfate, copper sulfate and 50% carbendazol.

Description

A kind of prescription and preparation method that contains the rare earth seed-pelleting dressing agent

One, technical field:

The present invention relates to a kind of prescription and preparation method that contains the rare earth seed-pelleting dressing agent, belong to agriculture field.

Two, background technology:

The open field live broadcast of seed exists many difficulties, and small-sized seed has only the sowing smoothly of the volume of increase.The plant seeds by airplane planting grasses and trees also has only the increase volume, gains in weight and could evenly broadcast underground layer, and bury.Because damage by disease and insect and animal have only sowing that seed is handled just and can prevent above-mentioned harm the harm of seed.Therefore, the preliminary treatment of seed is very necessary.

Three, summary of the invention:

The technical problem that the present invention solves: stimulate seed sprouting to take root; tachyauxesis; improve seed viability; and can prevent the harm of damage by disease and insect and animal to seed; simultaneously because the seed weight increase; volume increases, and has avoided seed with wind drift, the difficult problem of burying, and is suitable for a kind of prescription and manufacture craft that contains the rare earth seed-pelleting dressing agent of plant seeds by airplane planting grasses and trees especially.

Technical solution:

Prescription of the present invention (by weight percentage): attapulgite is that 13-50%, talcum powder are that 45-85%, mixeding acid rare-earth are that 0.8-5%, potassium nitrate are that 0.2-0.5%, potassium dihydrogen phosphate are that 0.2-0.5%, boric acid are that 0.2-0.5%, zinc sulphate are that 0.2-0.5%, copper sulphate are that 0.2-0.5%, 50% carbendazim are that 0.2-0.5% forms.

The attapulgite main component is Mg ₅Si ₈O ₂₀(HO) ₂(OH ₂) 4H ₂O.

Compounding method technical process of the present invention:

(1) mixeding acid rare-earth and attapulgite are put together is crushed to 260 orders and gets mixture No. 1.

(2) talcum powder be crushed to add behind 260 orders in No. 1, the mixture, mix No. 2, mixture.

(3) potassium nitrate, potassium dihydrogen phosphate, boric acid, zinc sulphate, copper sulphate be crushed to add behind 260 orders in No. 2, the mixture, mix No. 3, mixture.

(4) 50% carbendazim is crushed to adds behind 260 orders in No. 3, the mixture, mix the back packing and get final product.

The present invention determines after through up to a hundred formula tests and technology adjustment, and has reached Expected Results in actual applications.Through the seed of said preparation pill pelletizing coating, emerge fast, seedling neat, the survival rate comparison is according to being improved largely.Drawn in kind of the tree in large tracts of land plant seeds by airplane kind and obtained immense success, obtained gratifying result.

Process chart of the present invention.

Five, embodiment:

Embodiment 1:

(main component is Mg by attapulgite in the present invention ₅Si ₈O ₂₀(HO) ₂(OH ₂) 4H ₂O) be 27.2%, talcum powder is 70%, mixeding acid rare-earth is 1%, potassium nitrate is 0.3%, potassium dihydrogen phosphate is 0.3%, boric acid is 0.3%, zinc sulphate is 0.3%, copper sulphate is that 0.3%, 50% carbendazim is 0.3% to form.

Its technical process is as follows:

(1) be that 1% mixeding acid rare-earth and component are that 27.2% attapulgite is put together and is crushed to 260 orders and gets mixture No. 1 with component.

(2) be that 70% talcum powder is crushed to and adds behind 260 orders in No. 1, the mixture with component, mix No. 2, mixture.

(3) be that 0.3% potassium nitrate, 0.3% potassium dihydrogen phosphate, 0.3% boric acid, 0.3% zinc sulphate, 0.3% copper sulphate are crushed to and add behind 260 orders in No. 2, the mixture with component, mix No. 3, mixture.

(4) be that 0.3% 50% carbendazim is crushed to and adds behind 260 orders in No. 3, the mixture with component, mix the back packing and get final product.

Embodiment 2:

(main component is Mg by attapulgite in the present invention ₅Si ₈O ₂₀(HO) ₂(OH ₂) 4H ₂O) be 40%, talcum powder is 55.6%, mixeding acid rare-earth is 2%, potassium nitrate is 0.4%, potassium dihydrogen phosphate is 0.4%, boric acid is 0.4%, zinc sulphate is 0.4%, copper sulphate is that 0.4%, 50% carbendazim is 0.4% to form.

Its technical process is as follows:

(1) be that 2% mixeding acid rare-earth and component are that 40% attapulgite is put together and is crushed to 260 orders and gets mixture No. 1 with component.

(2) be that 55.6% talcum powder is crushed to and adds behind 260 orders in No. 1, the mixture with component, mix No. 2, mixture.

(3) be that 0.4% potassium nitrate, 0.4% potassium dihydrogen phosphate, 0.4% boric acid, 0.4% zinc sulphate, 0.4% copper sulphate are crushed to and add behind 260 orders in No. 2, the mixture with component, mix No. 3, mixture.

(4) be that 0.4% 50% carbendazim is crushed to and adds behind 260 orders in No. 3, the mixture with component, mix the back packing and get final product.

Use preparation of the present invention, method is simple, and expense is cheap, and is free from environmental pollution.Seed can prevent to be destroyed by damage by disease and insect and animal after treatment, and seed is not with wind drift during plant seeds by airplane, and it is dark to go into the soil, and emergence rate and survival rate increase substantially.
