Abstract
A long-acting synergist for nitrogen fertilizer is characterized in that the synergist comprises the following components (by weight): 65-95% of lignite; 4-34% of dicyandiamide; 1-31% of sodium tetraborate and zinc sulfate. The synergist is added into urea or ammonium bicarbonate according to the proportion of 0.5-15% by weight and is uniformly stirred, and the synergist can be applied according to the using method of common fertilizers. The long-acting fertilizer has the fertilizer effect period of 90-120 days, and can improve the nitrogen utilization rate of the fertilizer, promote the growth of crops and improve the yield of the crops.
Description
The present invention relates to a kind of synergistic agent that prolongs the fertilizer effectiveness phase.Specifically provide a kind of fertilizer efficiency period that can prolong chemical fertilizer bicarbonate of ammonia and urea, improve the fertilizer nitrogen utilization ratio, and it is degeneration-resistant to have a crop of enhancing, promotes plant growth, improves the nitrogenous fertilizer long-acting synergist of crop yield.
Chemical nitrogen fertilizer is a topmost chemical fertilizer in China's agriculture production as urea and bicarbonate of ammonia.But after being manured into soil, because the effect of soil urease, nitrobacteria makes it rapid decomposition, be about 35 days as the fertilizer efficiency period of bicarbonate of ammonia, the fertilizer efficiency period of urea is 50 days, and plant has little time to absorb, and the part chemical fertilizer just is lost.In recent years, both at home and abroad to improving nitrogen utilization efficiency, the research that prolongs fertilizer efficiency period has obtained considerable progress with application, as delays ureaclastic urease inhibitor, as aldehydes matters such as Resorcinol, can improve the utilization ratio of blood urea nitrogen effectively, prolongs fertilizer efficiency period.But this class phenols is slower in degraded in soil, and life-time service has to have no adverse effects to soil and crop and environment thereof becomes the problem that people pay close attention to.Can adopt Dyhard RU 100 to make additive to bicarbonate of ammonia, because Dyhard RU 100 is a latent curing agent, be again a kind of nitrate reductase inhibitor simultaneously, mix with bicarbonate of ammonia or eutectic is put and is manured into soil, can increase the absorption solidification effect of soil, reduce volatilization loss ammonium ion.Simultaneously can slow down or interrupt the reaction that ammonia-state nitrogen is converted into nitric nitrogen again, promptly reduce the loss of nitrogen in the leaching of nitric nitrogen and the soil that denitrification causes.But the addition of Dyhard RU 100 must suitably be difficult for support during actual the use and hold, simultaneously, this single bicarbonate of ammonia chemical fertilizer that contains Dyhard RU 100 of soil long-term application, required other trace element of plant can't be replenished, and the structure of soil will be degenerated, and the fertility of soil descends.
The purpose of this invention is to provide and a kind ofly all can play the synergistic agent that prolongs its fertilizer efficiency effect, this synergistic agent is added in urea or the volatile salt, not only can prolong the fertilizer efficiency period of chemical fertilizer, and can improve the nitrogen utilization efficiency of chemical fertilizer fertilizer urea and bicarbonate of ammonia.Simultaneously, this chemical fertilizer of soil application can promote plant growth, improves crop yield, and can improve Soil structure, increases soil fertility.
Nitrogenous fertilizer long-acting synergist of the present invention, on the basis of prior art, improve, it is with the nitrification inhibitor of Dyhard RU 100 as main nitrogenous fertilizer (urea and ammonium bicarbonate), it is characterized in that having increased crude substance again for the unfavorable factor that overcomes this single nitrification inhibitor, as one or more mixtures in brown coal, weathered coal or the peat as the auxiliary agent of Dyhard RU 100.On the one hand, the active group of crude substance brown coal, weathered coal or peat can improve fertilizer efficiency, and urease activity is had certain restraining effect, and the fertilizer efficiency period of nitrogenous fertilizer (urea and bicarbonate of ammonia) is prolonged, and improves certain nitrogen utilization efficiency.On the other hand, the humic acids functional group of these crude substance itself can provide crop alimentary, promotes the sorption and the hormonal action that promote growth of crop to nitrogen, is again good soil improvement agent, can improve the crumb structure of soil, increases the fertility of soil.In addition, for replenishing the trace element that crop generates required necessity,, add an amount of salt that contains above-mentioned element in the synergistic agent of the present invention, as sodium tetraborate, zinc sulfate, Sodium orthomolybdate, manganous sulfate etc. as boron, zinc, molybdenum, manganese element etc.The weight percent content of various components is in synergistic agent:
Crude substance: 65～95%
Dyhard RU 100: 4～34%
Boracic, zinc, molybdenum, manganese element salt: 1～31%
As the preferable synergistic agent of the present invention, the weight percent of each component is:
Crude substance: 79～91%
Dyhard RU 100: 8～20%
Boracic, zinc, molybdenum, manganese element salt: 1～13%
The preparation process of synergistic agent of the present invention is very simple, with crude substance pulverize, dry back and Dyhard RU 100 and salt be by weight mixing and stirring, also can pulverize mixture again, increase its homogeneity and can make synergistic agent.
Synergistic agent using method of the present invention is also very convenient, accounts for the ratio of chemical fertilizer weight 0.5～15% in synergistic agent, after synergistic agent and urea or bicarbonate of ammonia mixing and stirring, can use by the using method of common chemical fertilizer.Also can synergistic agent of the present invention be added in the production process of producing urea or ammonium hydrogen carbonate by above-mentioned weight percent, preparation long-acting carbamide or long-acting ammonium bicarbonate chemical fertilizer adopt this method, and synergistic agent can be brought into play its effect more fully.
The preparation of example 1 nitrogenous fertilizer long-acting synergist
Press brown coal 85%, Dyhard RU 100 14%, sodium tetraborate and zinc sulfate, stir in the input mixing tank for coating colors than with material after above-mentioned three kinds of pulverizing by the weight of 1: 1 mixture 1%, can obtain synergistic agent of the present invention.
The application test of example 2 synergistic agent of the present invention
Example 1 is made the synergistic agent of each, ratio in chemical fertilizer weight 8% is added to the system long-acting fertilizer that stirs in urea and the bicarbonate of ammonia respectively, makes the same simultaneous test of rice terrace with urea that does not add synergistic agent and bicarbonate of ammonia, and total rate of fertilizer application is identical, controlled release chemical fertilizer is only made base manure one time, once topdresses.Administering long-lasting urea increasing production of rice 10～20%; Administering long-lasting bicarbonate of ammonia volume increase 9～19%.As saving chemical fertilizer 20～25% by calculating with output.The fertilizer efficiency period of controlled release chemical fertilizer can reach 90～120 days.Use this long-acting fertilizer can alleviate the operations labor intensity of applying fertilizer between farming effectively.
