Abstract
The invention relates to a loss-control controlled-release fertilizer which is composed of urea, monoammonium phosphate, ammonium chloride, potassium chloride and ammonium bicarbonate. When the fertilizer is in use, an auxiliary material attapulgite is needed. The ratio of the attapulgite, urea, monoammonium phosphate, ammonium chloride, potassium chloride and ammonium bicarbonate is 6:34.15:31.71:19.51:4.88:9.76. The fertilizer is reasonable in preparation, can supply sufficient nutritive elements to soil in time, enhances the utilization ratio of the fertilizer on crops, reduces the fertilizer loss in the use process, and has higher actions on social permanent and steady development in the aspects of environment protection and energy saving.
Description
Technical field
The present invention relates to a kind of chemical fertilizer, especially a kind of control mistake, Controlled Release Fertilizer.
Background technology
Nutritive element in soil can because a variety of causes loss, and unfavorable to plant-growth, how supplementing the nutrient in soil in time and effectively to keep content, to become current research direction, therefore a kind of control mistake of development, Controlled Release Fertilizer, have good meaning.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of control mistake, Controlled Release Fertilizer, improving the utilization ratio of fertilizer on crop to reach, decrease the object of the loss of fertilizer in the process used.
One control of the present invention is lost, Controlled Release Fertilizer, and it is made up of urea, monoammonium phosphate, ammonium chloride, Repone K and bicarbonate of ammonia, and the ratio of this urea, monoammonium phosphate, ammonium chloride, Repone K and bicarbonate of ammonia is 34.15:31.71:19.51:4.88:9.76.
The invention still further relates to above-mentioned a kind of using method controlling mistake, Controlled Release Fertilizer, this using method comprises the following steps: add auxiliary material, this auxiliary material is made up of attapulgite, and the ratio of this attapulgite and this urea, this monoammonium phosphate, this ammonium chloride, this Repone K and this bicarbonate of ammonia is 6:34.15:31.71:19.51:4.88:9.76.
Urea is a kind of high density nitrogenous fertilizer, belongs to neutral readily avaiable fertilizer, not residual any objectionable impurities in soil, long-term application does not have detrimentally affect, and urea is organic nitrogenous fertilizer, the urase effect in soil, after being hydrolyzed into volatile salt or bicarbonate of ammonia, can effective utilization absorbed by crops.
It is optimum that monoammonium phosphate is used during plant growth as fertilizer, and monoammonium phosphate is in acid in soil, and in acid soil, it is better than general calcium, ammonium sulfate, also superior than other fertilizer in alkaline soils.
Ammonium chloride is a kind of quick-acting nitrogen chemical fertilizer, and nitrogen content is 24% ~ 25%, and soluble in water, water absorbability is larger than ammonium sulfate, and easy deliquescence is physiological acidic fertilizer, is applicable to the crops such as corn, wheat, paddy rice, Chinese sorghum, vegetables, crudefiber crop.The fibre crops such as flax, hemp are used the better effects if of ammonium chloride, especially has fortifying fibre toughness and pulling force to cotton crudefiber crop and improve effect of quality, because chlorine has the effect of fortifying fibre toughness and pulling force.
Repone K is being agriculturally a kind of potash fertilizer, and its fertilizer efficiency is fast, is directly applied to farmland, and Neng Shi soil lower floor moisture rises, and has the effect of drought resisting.
Bicarbonate of ammonia, also known as carbon ammonium, be a kind of carbonate, nitrogenous about 17.7%, can be used as nitrogenous fertilizer, disappear because it can be analyzed to NH3, CO2 and H2O tri-kinds of gases, thus fertile also known as gas, and bicarbonate of ammonia is without (sulphur) acid group nitrogenous fertilizer, its three components are all the nutrients of crop, not containing harmful intermediate product and final degradation production, long-term application does not affect soil property, is one of safest nitrogen fertilizers.
The invention has the beneficial effects as follows: a kind of control is lost, Controlled Release Fertilizer; preparation rationally; can be the sufficient nutritive element of the timely supply of soil; improve the utilization ratio of fertilizer on crop; decrease the loss of fertilizer in the process used; pollute for protection of the environment, save energy, has the effect of the lasting stable development of higher society.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment 1
One control of the present invention is lost, Controlled Release Fertilizer is applicable to general soil, it is made up of urea, monoammonium phosphate, ammonium chloride, Repone K and bicarbonate of ammonia, and the ratio of this urea, monoammonium phosphate, ammonium chloride, Repone K and bicarbonate of ammonia is 34.15:31.71:19.51:4.88:9.76.
Control is lost: the loss controlling fertilizer.Mainly utilize the effect of the wrap film outside fertilizer, be configured can form wrap film in the outside of fertilizer according to above-mentioned formula.
Controlled release: the release controlling fertilizer.No matter that cash crop or farm crop are in different periods, there is certain difference in the demand for NPK fertilizers, and different cash crop and farm crop are for period of the demand of fertilizer being not quite similar (mainly three phases: young stage (base fertilizer), animated period (the most important link of growth, fertilizer requirement are maximum), bear fruit productive phase (maintenance fertilizer)).Mainly utilize the wrap film outside fertilizer and the release mediator agent in production process.
In use, need to add auxiliary material, this auxiliary material is made up of attapulgite, and the ratio of this attapulgite and this urea, this monoammonium phosphate, this ammonium chloride, this Repone K and this bicarbonate of ammonia is 6:34.15:31.71:19.51:4.88:9.76 for this control mistake, Controlled Release Fertilizer.
Embodiment 2
Carry out to paddy rice on 10 mu of ground the effect control experiment of product Common compound fertilizer Yukon of the present invention fertilising, comparing result is as shown in table 1 below.
