Preferably, the nitrification inhibitor is N-serve, guanyl thiourea, dicyandiamide, 2- sulfanilamide (SN) thiophenes
One or more in azoles.
Preferably, the urease inhibitor is 1,4-benzoquinone, quinhydrones, diaminobenzene phosphate, thiocarbamide and hexanoyl hydroxamic acid
In one or more.
Preferably, the rare earth element is the one or more in lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium.
Preferably, it is 1 that the thickener, which includes mass ratio,:1 methylcellulose and sodium carboxymethylcellulose.
The present invention proposes a kind of preparation method of slow release long-acting compound fertilizer, comprises the following steps：
(1) urea, ammonium sulfate, potassium sulfate, monoammonium phosphate are put into agitating device and are uniformly mixed, obtain the first mixing
Object；
(2) kapok is put into ammonia spirit to impregnate and for 24 hours, then takes out kapok and be warming up to the heating rate of 5 DEG C/min
120 DEG C, and constant temperature 1.5h oxidation kapoks；
(3) by step (2), treated that kapok is put into retort activates, and is passed through inert gas shielding, then with 8-
The heating rate of 11 DEG C/min is warming up to 700 DEG C, and activates 65-70min in constant temperature, finally stop heating and be continually fed into lazy
Property gas, is down to room temperature and obtains kapok based active carbon fiber；
(4) magnesium sulfate, boric acid, rare earth element, nitrification inhibitor, urease inhibitor, toluene sulfochloride are put into reaction
In kettle, and 20 DEG C of water is added in into reaction kettle, stirring 10min forms the first solution；
(5) kapok based active carbon fiber and thickener are added in into the first solution, is dried under reduced pressure and persistently stirs, until the
Moisture in one solution is evaporated, and obtains the second mixture；
(6) the second mixture is added in the agitating device equipped with the first mixture, is uniformly mixed and just obtains sustained release length
Imitate compound fertilizer.
By adopting the above-described technical solution, the beneficial effects of the invention are as follows：
The slow release long-acting compound fertilizer of the present invention is using kapok based active carbon fiber as carrier, kapok based active carbon fiber tool
There are porous structure, and large specific surface area, be conducive to magnesium sulfate, boric acid, rare earth element, nitrification inhibitor, urease inhibitor, toluene
The relatively low component of sulfonic acid chloride equal size deposits on it, at the same with a large amount of groups of urea, ammonium sulfate, potassium sulfate, monoammonium phosphate etc.
When point being mixed, a part for a large amount of components can be also adsorbed on kapok based active carbon fiber, when to applying fruit trees with fertilizer, largely
Another part of component is first absorbed by fruit tree, and the another part for a large amount of components being attached on kapok based active carbon fiber and is contained
It measures relatively low component slowly to discharge, plays the role of sustained release, while the component being attached on kapok based active carbon fiber will not；And
The caking for effectively preventing fertilizer each component of toluene sulfochloride in the relatively low component of content, convenient for the storage of fertilizer；And
The preparation method of slow release long-acting compound fertilizer it is simple for process, and prepare kapok based active carbon fiber preparation process compared with
Existing preparation process is simple, and the large specific surface area of the kapok based active carbon fiber prepared.

Now to conventional extended release long-acting complex fertilizer, first group of slow release long-acting compound fertilizer, second group of slow release long-acting compound fertilizer and
Three groups of slow release long-acting compound fertilizers respectively specifically test hardened time, leachability and influence to apple tree etc..
The hardened time：Four groups of fertilizer are taken into a certain amount, are packed respectively with slow release long-acting compound fertilizer pocket, then
Be placed under similary environment, observe four groups of fertilizer and the hardened times occur, as table one (four groups of slow release long-acting compound fertilizers it is hardened when
Between).
The hardened time of one or four groups of slow release long-acting compound fertilizers of table
Conventional extended release long-acting complex fertilizer occurred as soon as the phenomenon that hardened when 23 days, and the fertilizer of the present invention is in storage
Do not occur the phenomenon that hardened in 1 year, slow release long-acting compound fertilizer of the invention has the ability of very strong anti-caking, convenient for length
The storage of time.
Leachability：Nutrient namely in fertilizer is since rainfall is lost in rain water runoff and the volatilization of itself, together
In plot, the soil that 20 pieces of areas are 9 ㎡ is chosen, is divided into four groups, then every group of soil for including 5 piece of 9 ㎡ takes routine respectively
Slow release long-acting compound fertilizer 10kg, first group of slow release long-acting compound fertilizer 10kg, second group slow release long-acting compound fertilizer 10kg and the 3rd group
Slow release long-acting compound fertilizer 10kg is discharged on different groups of soil, and application has the fertilizer of 2kg on every block of soil, and then detection is every
Kind nutrient is preferably minimized the time of detection limit, and during experiment, simulation normal weather is in every seven days of experiment
Last day is rain making such as table two (the lasting timeliness of nutrient).
The lasting timeliness of two nutrient of table
From experiment it can be seen that common fertilizer fertilizer efficiency loss after rainfall is run into is very serious, and the slow release long-acting of the present invention
Even if a part of nutrient when rainfall is run into, still can be stored in the hole table of kapok based active carbon fiber by compound fertilizer
In face, the loss of fertilizer efficiency is effectively prevented.
40 flower ox apple trees in the same size and that yield is almost identical are chosen, are divided into 4 groups, every group 10 colored ox apples
Tree applies a kind of fertilizer to one group of flower ox apple tree, then every group of apple production and single apple weight is counted, such as table
Three (influences of four groups of slow release long-acting compound fertilizers to apple)
Influence of three or the four groups of slow release long-acting compound fertilizers of table to apple
From experimental data it can be seen that yield and single apple weight of the slow release long-acting compound fertilizer of the present invention to apple
Influence has larger improvement compared with conventional extended release long-acting complex fertilizer, and the slow release long-acting compound fertilizer of the mainly present invention can be grown
Shi Chixu is that apple tree provides nutrition composition, extends the time of fertilizer, and the loss of the nutrient of another aspect fertilizer subtracts
Small, the fertilizer efficiency of fertilizer is fully utilized.
Embodiments described above is part of the embodiment of the present invention, instead of all the embodiments.The reality of the present invention
The detailed description for applying example is not intended to limit the scope of claimed invention, but is merely representative of the selected implementation of the present invention
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without creative efforts
Every other embodiment, belongs to the scope of protection of the invention.
