Description

Compound phosphoric acid potassium dihydrogen solution and production method thereof

Technical field

The present invention relates to a kind of agricultural fertilizer and production method thereof, especially compound phosphoric acid potassium dihydrogen solution and production method thereof.

Background technology

Agricultural fertilizer for spraying on leaf surface mostly is the solid phosphoric acid potassium dihydrogen at present, also there are some to utilize the meal of metathesis principle preparation, utilize the multi-component potassium dihydrogen phosphate liquid of p-nitrophenol sodium in addition, but because the poorly soluble and not congruent factor of fertilizer efficiency causes its poor effect as permeate agent.

Summary of the invention

It is fast that one of purpose of the present invention provides a kind of crop absorption, avoids a word used in person's names anti-, improves the compound phosphoric acid potassium dihydrogen solution of fertilizer efficiency;

Two of purpose of the present invention provides a kind of production method of above-mentioned fertilizer.

Technical scheme of the present invention is as follows:

A kind of compound phosphoric acid potassium dihydrogen solution, it basic composition is, and contains the EDTA of 0.02-0.03%, the FeSO of 0.12-0.16% ₄, 0.07-0.08% ZnSO ₄, 0.03-0.04% MgSO ₄, 0.02-0.03% CuSO ₄, 0.005-0.007% CaSO ₄, 0.005-0.007% MnSO ₄, the ammonium molybdate of 0.001-0.002%, the plant-growth regulator of 0.1-0.2%, the azone of 0.5-1%, all the other are potassium primary phosphate;

Plant-growth regulator wherein can be α-Nai Yisuan, Plant hormones regulators,gibberellins or ethrel;

The production method of compound phosphoric acid potassium dihydrogen solution comprises the following steps:

A, in industrial water purification, add the EDTA of 0.02-0.03%, the FeSO of 0.12-0.16% successively ₄, 0.07-0.08% ZnSO ₄, 0.03-0.04% MgSO ₄, 0.02-0.03% CuSO ₄, 0.005-0.007% CaSO ₄, 0.005-0.007% MnSO ₄, 0.001-0.002% ammonium molybdate, prepare artificial mineralized water;

B, in the artificial mineralized water for preparing, add the solid phosphoric acid potassium dihydrogen of 16%-18%;

C, adding the plant-growth regulator of 0.1-0.2% again, specifically can be α-Nai Yisuan, Plant hormones regulators,gibberellins or ethrel;

D, the azone that adds 0.5-1% at last get final product.

The present invention is to contain the mineralized water of trace element, be equipped with plant absorbing activator naphthylacetic acid, with the azone is that permeate agent prepares compound phosphoric acid potassium dihydrogen solution, can accelerate the absorption of farm crop, a word used in person's names that reduces Different Nutrient Elements is anti-, increases the difficult trace element of carrying of cane comprehensively, improved fertilizer efficiency greatly, can make farm crop increase output 5-30% through experiment, and nontoxic noresidue, be beneficial to mechanical work.
