The auxin of Jia Ruing also has α-Nai Yisuan, quinine except that 30 alkanols in the present invention.They constitute the carrying out that composite hormone can promote all processes of plant body, can also promote cell division, protein and nucleic acid are synthetic, and can quicken plant growth, shorten growth cycle, nutriment is carried well, nitrogen, phosphorus, potassium and other nutriment are rationally distributed in plant corpus turn to reproductive organs to promote to yield positive results from nutrition organs.The consumption of above-mentioned various hormones then is respectively: (is basic calculation with 100 parts of potassium dihydrogen phosphates (95%))
0.07～0.08 part of consumption of 30 alkanols (90%) (weight)
0.02～0.03 part of consumption of quinine (98%) (weight)
0.02～0.03 part of consumption of α-Nai Yisuan (98%) (weight)
At each different growing stage of plant can adjust add the hormone kind as wherein one or more.
Also add a kind of honeybee worm and lure and draw information agent such as royal jelly in raw material of the present invention, it can lure insects such as the honeybee raising fruit-setting rate of pollinating.Royal jelly itself also is a kind of hormone thereby also has the effect same with above-mentioned hormone.It is 0.05 part (weight) that this honeybee worm lures the usage amount of drawing information agent.
Need to add in the preparation process of product of the present invention that to expand agent be efficient surfactant, the molecular surface tension force that it can reduce this product solution is sprayed on the plant easily attached on the cured matter blade face, improves absorption ratio and brings into play fertilizer efficiency better.This expands agent and adopts nontoxic natural plants fatty alcohol derivative such as laruyl alcohol epoxy ether sodium sulphate, lauric alcohol epoxy ether sodium sulphate etc., 0.075 part of its usage amount.
Moisture prevents the hygroscopic agent that moisture exosmoses in the product as containing also to adopt the polyacrylamide water-absorbing resin in the preparation process of product of the present invention, makes product become dry pulvis, easy to use and storage, and its usage amount is 0.5 part.
Also adopt ASE as anticaking agent in the preparation process of product of the present invention, making its usage amount of the non-sclerous caking of this product long-term storage is 1.0 parts.
In the preparation process of product of the present invention, adopt the EDTA chelating agent, the salt solubility of chelating attitude is improved, the moisture content in the solution is reduced to bottom line, be beneficial to prepare solid powder, make it its water content and only account for 2% of total inventory, the usage amount of this chelating agent is 6～10 parts (weight).
Above-mentioned honeybee worm lure draw information agent, expand agent, the usage amount of water-absorbing resin, anticaking agent, chelating agent is basic calculation with 100 parts of potassium dihydrogen phosphates (95%) all.
The concise and to the point flow process of plant growth substances its preparation method of the present invention is as follows:
Its concrete preparation process is:
1. the sulphate (except the cerous sulfate) of all specified quantities in the raw material is added in 80 ℃ the low amounts of water, adds borax then, the water yield only accounts for 1/3 of inventory becomes pasty state.
2. the EDTA chelating agent that adds specified quantity, and PH is transferred to 6～7 stir and make it dissolving.About 2 hours of used time, the available hydrogen amine-oxides transfers to 6～7 with the pH value of liquid during if any insoluble matter, and the then all dissolvings of insoluble matter this moment maintain the temperature at 80～95 ℃, and solution is transparent blue black, and various elements are easily by the chelating attitude of crop absorption.
3. in chelating liquid, add the cerous sulfate of specified quantity and remaining non-sulfuric acid salt raw material and honeybee worm and lure the fine fodder that obtains that draws information agent, composite hormone and stirring.Added non-sulfuric acid salt raw material has the composite hormone of boric acid, strontium nitrate, ammonium molybdate, potassium bromide and dilution dissolving.30 alkanols, quinine, α-Nai Yisuan, also have the honeybee worm to lure to draw the information agent royal jelly, the product that obtains after fully stirring is fine fodder.
