Abstract
The nitrogen fertilizer synergist consists of humic acid 25-45 wt%, zeolite powder 8-50 wt% and cyanoguanidine 2-30 wt%. The present invention also provides one method of increasing the effect of nitrogen fertilizer, that is, to mix the said nitrogen fertilizer syngergist with nitrogen fertilizer in the weight ratio between the synergist and the pure nitrogen amount in the nitrogen fertilizer of 1 to 5-35. The present invention can increase the utilization of nitrogen fertilizer by 10-20%.
Description
The present invention relates to a kind ofly prevent the nitrogen fertilizer potentiating agent of ammonia volatilization and nitrogenous fertilizer is carried out the synergic method.
Existing nitrogen fertilizer potentiating agent comprises two big classes, and a class is to add some particular matters to change chemistry, the physical property of nitrogenous fertilizer when nitrogen fertilizer production, nitrogenous fertilizer is manured into soil afterwards slowly discharges; Another kind of is to add some materials when nitrogen application, and the form transformation of nitrogen and absorption were to reach the slowly purpose of release of control nitrogen after control nitrogenous fertilizer was manured into soil.
The research of nitrogen fertilizer potentiating agent has tangible economic benefit, ecological benefits and social benefit.For a long time, add one or more materials in proportion and mix with nitrogenous fertilizer in nitrogenous fertilizer, the control nitrogen discharges and transforms or the absorption nitrogen is kept away and suffered too fast leaching loss or volatilization, is the technology of a kind of both economical and prolongation fertilizer effectiveness phase of being easy to accept.The core substance that is added is called nitrogen fertilizer potentiating agent, and mainly based on the artificial compound.At present domestic representational product is that nitrogen fertilizer potentiating agent (as two cyanogen ammoniums) is joined (as weathered coal) among the carrier, and the user in use is mixed in proportion their mixture and reaches the purpose of prolongation fertilizer effectiveness phase with nitrogenous fertilizer (as urea).
Have on the market that a kind of to be that the nitrogenous fertilizer of main carrier components is slow with weathered coal execute agent, but, be black, be easy to be adsorbed in body surface because the proportion of weathered coal is less.The in use usually easy and nitrogenous fertilizer layering of this type of synergistic agent causes and uses inequality, runs into the wind sky and is difficult to apply specified location, increases labour intensity; If the user directly uses the hand applying fertilizer, very easily be adsorbed on as the weathered coal of carrier and make article on hand dirty or to pollute human organ.The inconvenience of such synergistic agent on using will limit it and popularize; Nitrogen fertilizer potentiating agent cost based on the artificial compound is higher.
An object of the present invention is to provide a kind of nitrogen fertilizer potentiating agent that prevents ammonia volatilization.Thereby a kind of simple and practical, with low cost, pollution-free and avirulent liquid nitrogen fertilizer synergistic agent is provided, is suitable for composite fertilizer factory and produces durable composite fertilizer and use as extraordinary cash crop nitrogen fertilizer potentiating agent.
Another object of the present invention provides a kind ofly carries out the synergic method to nitrogenous fertilizer.
Zeolite is can the adsorption of nitrogen fertilizer additive as the cardinal principle of natural nitrogen fertilizer potentiating agent carrier, nitrogen fertilizer additive is mixed, and mix with nitrogenous fertilizer easily; Action principle as nitrogen fertilizer potentiating agent is to adsorb ammonium ion (NH
4 +-N) make it exempt from too fast nitrification, leaching loss and volatilization.Zeolite is a natural mineral, contains various nutrient elements, forms zeolite powder after being milled down to more than 100 orders, and zeolite powder has porousness, and inside and outside specific surface area is bigger, has the intensive adsorption function.Proportion is big than weathered coal, is easy to mix with fertilizer, and is convenient when using, and pollutes few.FA is the humic acids that weathered coal utilizes acid extraction, except that other characteristics, has the function that nitrogenous fertilizer is slowly discharged.FA has the effect that strengthens microorganism active and plant-growth regulator is provided.Two cyanogen ammoniums are a kind of nitrogen fertilizer potentiating agents commonly used.To this, we have carried out screening to these crude substance as the nitrogen fertilizer potentiating agent carrier and have prevented the experimental study of ammonia volatilization.
The invention provides a kind of nitrogen fertilizer potentiating agent that prevents ammonia volatilization, contain humic acids, zeolite powder, two cyanogen ammoniums, its part by weight are humic acids: zeolite powder: two cyanogen ammoniums=0.25～0.45: 0.08～0.5: 0.02～0.3.In nitrogen fertilizer potentiating agent of the present invention, the granularity of zeolite powder is preferably 80～100 orders.
The present invention also provides a kind of nitrogenous fertilizer has been carried out the synergic method, is included in nitrogen fertilizer potentiating agent of the present invention and nitrogenous fertilizer to be carried out the blended step before the nitrogen application, and wherein, the weight percent of pure nitrogen level is 1: 5～35 in nitrogen fertilizer potentiating agent and the nitrogenous fertilizer.
Nitrogenous fertilizer described in the method for the present invention can be any nitrogenous fertilizer well known in the prior art, also can be the composite fertilizer of containing other fertilizer such as phosphate fertilizer.Wherein, humic acids (representing with FA in this specification sheets) is the humic acids that adopts conventional nitric acid extraction method to extract, and humic acids is to utilize soda acid lixiviate weathered coal or peat and the extract that obtains.
Liquid synergistic agent of the present invention can be produced by the following method:
The extraction of (1.FA humic acids) stoste: adopt weathered coal to add method of nitric acid and extract.
2. zeolite powder production method: adopt mechanical means to be milled down to more than 80 orders.
3. when using, at first will an amount of two cyanogen ammoniums with after an amount of zeolite powder mixes, mix with an amount of FA stoste again, after thorough mixing is even an amount of water of adding the liquid nitrogen fertilizer synergistic agent.
Synergistic agent of the present invention can improve utilization rate of nitrogen fertilizer 10～20% in agriculture production.
