Description
Technical field:
The present invention relates to a kind of synergistic agent, particularly relate to a kind of fertilizer synergistic agent, reach preparation method and application.
Background technology:
At present, the mankind are being faced with the population growth, the serious challenge such as minimizing, environmental pollution of ploughing, and in order to satisfy the demand of the growing grain of people and other agricultural-food, must increase output, and apply the main means that chemical fertilizer is an agricultural produce.
Though traditional fertilizer such as diammonium phosphate, bicarbonate of ammonia, ammonium sulfate etc. can be directly by plant absorbing, disadvantage is that volatilization is fast, utilization ratio is low, plant absorbing is few, influence environment.Urea belongs to amides nitrogenous fertilizer, because it is in soil in the decomposition course, needed for three steps transformed: the first step, earlier discharge the urine enzyme by bacterium, fungi, actinomycetes, form volatile salt and bicarbonate of ammonia behind the urine enzyme decomposing urea, and they very easily are decomposed into ammonia, carbonic acid gas, water, a large amount of easily volatilizations, cause direct economic loss, the urea utilization ratio reduces thus; In second step, volatile salt and bicarbonate of ammonia are decomposed into nitrite nitrogen by nitrite bacteria, and nitrite nitrogen is owing to be negatively charged ion, are not easy by negatively charged ion-soil colloid particle adsorbedly, cause loss; In the 3rd step, the nitrite nitrogen element is decomposed by nitrobacteria, become the negatively charged ion nitric nitrogen, and the as easy as rolling off a log loss of nitric nitrogen causes the loss for the third time of urea.Lose very seriously, the utilization ratio of common urea has only about 30%.And life-time service easily causes soil compaction, lacks micro-, soil fertility decline.
Summary of the invention:
The objective of the invention is to, solve the deficiencies in the prior art, a kind of enhancing fertilizer efficiency is provided, overcome soil fertility and descend, replenish the fertilizer synergistic agent of soil trace element.
Another object of the present invention provides the preparation method of above-mentioned fertilizer synergistic agent.
The invention still further relates to the application of above-mentioned fertilizer synergistic agent when combining with chemical fertilizer.
Above-mentioned purpose of the present invention can realize by following technical scheme:
Fertilizer synergistic agent of the present invention is made up of following raw materials by weight:
Humic acids 50%-70%
Microelement composition 30%-50%.
Wherein said microelement composition is made up of the following raw materials according that accounts for the microelement composition total weight percent: calcium sulfate 35%-70%, sal epsom 10%-20%, borax 0.5%-1%, ferrous sulfate 2.75%-5.5%, manganous sulfate 0.5%-1%, zinc sulfate 0.5%-1%, copper sulfate 0.5%-1%, ammonium molybdate 0.25%-0.5%.
The preparation method of fertilizer synergistic agent of the present invention comprises by following steps and forming:
(1) is mixed with microelement composition by the following raw materials according that accounts for the microelement composition total weight percent: calcium sulfate 35%-70%, sal epsom 10%-20%, borax 0.5%-1%, ferrous sulfate 2.75%-5.5%, manganous sulfate 0.5%-1%, zinc sulfate 0.5%-1%, copper sulfate 0.5%-1%, ammonium molybdate 0.2 5%-0.5%;
(2) get the humic acids that accounts for described fertilizer synergistic agent total weight percent 50%-70%, add the microelement composition that accounts for described fertilizer synergistic agent total weight percent 30%-50%;
(3) carry out granulation by prilling granulator, again by the heating unit heating, drying;
(4) after the oven dry, filter out the single-size of humic acids trace element, obtain the fertilizer synergistic agent finished product with roller grizzly.
As preferably, the prilling granulator described in the step (3) can be that diameter is the pelletizing disks of 1-2 rice.Heating unit can be a process furnace, and heating 18-25 rice cylinder continues 10-30 minute to 600-800 ℃.
The application of fertilizer synergistic agent of the present invention when combining with chemical fertilizer comprises the following step, and it is standby by the pack of 35-45 kilogram amount to get chemical fertilizer respectively; It is standby by the pack of 5-15 kilogram amount to get humic acids trace element particle; Can mix to spare and use again: chemical fertilizer 70%-90% with above-mentioned raw materials by following weight ratio during fertilising; Humic acids trace element particle 10%-30%.
The present invention has following advantage:
(1) can activating soil, overcome and harden.Use common chemical fertilizer can make soil compaction, secondary salinization, life-time service, soil fertility descends, and structure deteriorate causes the underproduction even total crop failure.Humic acids can chessom, overcomes and hardens, and recovers soil fertility, improves output, and very magical effect is arranged.
(2) utilization ratio of raising urea, the saving fund reduces and drops into, and increases the benefit.Because the loss of fertilizer, utilization ratio has only about 30%, wastes very serious, and because adsorption, the complexing action of humic acids, can effectively improving the soil effect, the loss of minimizing urea, increase operation rate, reduce input-output ratio, increase the benefit, not only get bumper crops but also have a good harvest.
(3) fertilizer synergistic agent is used in combination with chemical fertilizer, and competent nitrogen element not only can be provided, and for soil provides the trace element of capacity, can improve crop yield rapidly, replenishes soil fertility.
