The synergist can raise the utilization of phosphorus in ammonium phosphate by 5-10%, the utilization of nitrogen by 10-20%. The addition of zeolite can increase the yield of ammonium phosphate and production of chemical fertilizer and save power and material, the synergist can reduce the leaching and volatilization of chemical fertilizer and this is favourable to environment protection.
Description
The invention relates to a fertilizer synergist, in particular to a synergist using zeolite as ammonium phosphate.
At present, the utilization rate of chemical fertilizers in China is not high, and the total utilization rate of the chemical fertilizers is 25%. The ammonium phosphate comprises monoammonium phosphate and diammonium phosphate, and the molecular formulas of the ammonium phosphate and the diammonium phosphate are respectively NH4H2PO4And (NH)4)2HPO4Its active ingredient P2O5And NH4 +Are dissolved in water and are easy to leach away along with the water content of soil, NH4 +The ammonium phosphate is the most common N, P compound fertilizer at present, and the utilization rate is not high, thereby wasting fertilizer resources and increasing crop cost.
The invention aims to provide a zeolite ammonium phosphate synergist, which is applied by mixing the synergist with low cost and ammonium phosphate, can improve the fertilizer utilization rate of the ammonium phosphate, and further achieves the purposes of saving fertilizer resources, increasing the benefit of fertilizer production enterprises, reducing agricultural investment and realizing high yield and low consumption.
The technical scheme of the invention is as follows:
the zeolite synergist is prepared by air drying natural zeolite, pulverizing into powder, granulating to obtain granules of 60-100 meshes, granulating in a granulator to obtain round granules of 1-2mm in diameter, sieving, oven drying, metering, and packaging.
The synergist is used for being mixed with ammonium phosphate to form zeolite ammonium phosphate.
The zeolite ammonium phosphate synergist is mixed with ammonium phosphate, and the weight of the synergist accounts for 10-40% of that of the zeolite ammonium phosphate.
The synergistic action mechanism is as follows:
the natural Zeolite (Zeolite) is an alkali or alkaline earth metal aluminosilicate mineral, has huge surface area, pore channels accounting for 50% of the total volume, large electrostatic attraction and dispersion force due to the unique three-dimensional framework structure and crystallization chemical property of the Zeolite, has the characteristics of thermal stability and acid and alkali resistance, and has very outstanding exchange adsorption performance on anions, cations and molecules. The natural zeolite has rich resources and low cost.
1. The natural zeolite powder has strong adsorption capacity and desorption capacity to nitrogen and phosphorus in ammonium phosphate.
Measuring NH of 60-100 mesh mixed size fraction zeolite powder to diammonium phosphate by indoor measurement method4 +-N、HPO4 2-H2PO4 -Ion adsorption and desorption capacity, and treatment content: (1) (NH)4)2HPO41g + Zeolite powder 0g (containing Zeolite 0%) (2) (NH)4)2HPO41g + Zeolite powder 0.053g (containing Zeolite 5%) (3) (NH)4)2HPO41g + Zeolite powder 0.110g (containing Zeolite 10%) (4) (NH)4)2HPO41g + Zeolite powder 0.250g (containing Zeolite 20%) (5) (NH)4)2HPO41g + Zeolite powder 0.430g (containing Zeolite 30%) (6) (NH)4)2HPO41g + Zeolite powder 0.670g (containing Zeolite 40%) (7) (NH)4)2HPO4The results of measurement of 1g + 1.000g (containing 50% zeolite) of zeolite powder are shown in tables 1 and 2.
TABLE 1 measurement resultsShows that the natural zeolite powder is respectively mixed with diammonium phosphate in different contents of 5-50%, and the NH of the zeolite is added into the fertilizer4 +N has adsorption capacity, and the nitrogen absorption amount is 16-22.4mg/g zeolite, and the adsorbed nitrogen containsThe release rate is 72.3-97.3%.
The results of the measurement in Table 2 show that the natural zeolite powder is respectively mixed with diammonium phosphate in different content of 5-50%, the zeolite can absorb phosphate radicals of the fertilizer, the absorbed phosphorus is 18.9-45.5mg/g of zeolite, and 48-99.4% of the adsorbed phosphorus is easy to release.
The released nitrogen and phosphorus can be absorbed and utilized by crops, and the adsorption ⇌ release is a dynamic process and is a fertilizer retention mechanism for reducing fixation of the fertilizer by soil and leaching loss of the fertilizer by underground water by zeolite.
2. The zeolite can activate the residual ineffective nitrogen and phosphorus elements in the soil, increase the absorption of 24-35% of phosphorus from the soil by crops, increase the absorption of 10.3-16.9% of nitrogen, and is beneficial to the growth and development of the crops. For example: the zeolite and ammonium phosphate are mixed and applied into soil, and Cp (zeolite) and fertilizer nitrogen are combined into Cp-NH4Ammonium type zeolite reacts with ineffective calcium phosphate in soil to generate soluble calcium ammonium phosphate or ammonium phosphate which can be absorbed and utilized by crops. The function is especially significant in neutral and calcareous soil.
3. The zeolite has normal and negative charges, the negative charge of the zeolite is 79.13 milliequivalents/100 g and the positive charge of the zeolite is 3.66 milliequivalents/100 g measured by an ammonium chloride method, the zeolite not only adsorbs cations in soil, but also adsorbs various anions which are not easily adsorbed by soil colloid, and the zeolite has a function which is not possessed by common soil and is beneficial to improving the fertilizer efficiency of the fertilizer.
4. The zeolite is mixed with chemical fertilizer for application, so that the volatilization loss of nitrogen can be reduced. The ammonium phosphate and the urea both generate volatile ammonium ions when applied to the soil, indoor simulation tests prove that the zeolite can reduce the volatilization loss of nitrogen in the urea by 3.4-16.8%, and the nitrogen volatilization mechanism of the zeolite and the ammonium phosphate is reduced by applying the zeolite and the ammonium phosphate in a mixing way, which is the same as that of the urea.
The invention has the advantages that: 1. by using32P tracing technology and field test prove that the zeolite synergist can improve the utilization rate of ammonium phosphate and phosphorus by 5-10 percent and improve the utilization rate of nitrogen by 10-20 percent, and the zeolite synergist reaches the advanced level of the utilization rate of domestic and foreign fertilizers. 2. The addition of zeolite can increase the production of domestic monoammonium phosphate by 10-15%, improve the domestic market occupancy of domestic ammonium phosphate, and change the concept of relying on American diammonium phosphate. 3. The zeolite synergist added fertilizer plant can increase the yield of the fertilizer by 10 percent, save a large amount of energy and materials, and save 500 yuan for farmers when buying one ton of synergistic monoammonium phosphate compared with buying the imported diammonium phosphate. 4. The synergist reduces the leaching and volatilization of the fertilizer, reduces the pollution of the fertilizer to soil, underground water, rivers and atmosphere, and is beneficial to environmental protection.
The present invention is further illustrated by the following examples.
1. Zeolite field test for improving utilization rate of monoammonium phosphate phosphorus
The test results are shown in Table 3. In the table monoammonium phosphate is abbreviated monoammonium and zeolitic monoammonium phosphate is abbreviated zeolitic monoammonium, and the same is abbreviated in the following table.
Through field tests, the research result of a difference method shows that the phosphorus utilization rate of the fertilizer for the whole corn plant containing 10%, 20% and 30% of zeolite monoammonium phosphate applied to corn is 12.4%, 13.6% and 12.8%, is respectively 1.6%, 2.8% and 2.0% higher than that of the fertilizer for the whole corn plant containing the same amount of pure monoammonium phosphate, is increased by 14.8-25.9%, and is respectively 3.9%, 5.1% and 4.3% higher than that of the fertilizer for the whole corn plant containing the same amount of pure monoammonium phosphate (the amount of the zeolite ammonium phosphate is the same as that of the pure monoammonium phosphate), and is increased by 45.9-60%.
2. In 1995, 33 small-area tests and positioning tests for improving the fertilizer efficiency of monoammonium phosphate and diammonium phosphate are carried out on crops such as wheat, millet, corn and the like on 12 soils with different fertility in the urban areas of Chifeng by 1991-:
(1) the results of the field plot experiment for increasing the fertilizer efficiency of monoammonium phosphate by zeolite are shown in tables 4-7.
The treatment content of table 4 is control without fertilization, and the applied pure monoammonium phosphate and monoammonium phosphate containing 10% -40% zeolite were 17.5 kg/acre. From tables 4 and 5, it can be seen that the use of four zeolite monoammonium phosphates containing 10% to 40% zeolite in wheat has the same yield increasing effect as the use of the same amount of pure monoammonium phosphate, and the yield difference between each treatment and the control reaches a very significant degree. The net income increase of four kinds of zeolite monoammonium phosphate is 22.82-33.9 yuan per mu, which is higher than the net income increase of 22.2 yuan per mu. The grain increasing value of the four zeolite monoammonium phosphate fertilizers is higher than that of pure monoammonium phosphate fertilizers.
From tables 6 and 7, it can be seen that the use of four zeolite monoammonium phosphates containing 10% to 40% zeolite in millet has the same yield increasing effect as the application of the same amount of pure monoammonium phosphate, and the yield difference between each treatment and the control reaches a significant degree. The acre net income of applying two kinds of zeolite monoammonium phosphate containing 10% and 20% of zeolite is higher than that of applying pure monoammonium phosphate. The grain increasing value of the three zeolite monoammonium phosphate fertilizers which are applied by 10 to 30 percent is higher than the grain increasing value of the pure monoammonium phosphate fertilizers.
(2) Zeolite fertilizer efficiency improvement field plot experiment of diammonium phosphate
The test results are shown in tables 8-13. In the table, diammonium phosphate is abbreviated as diammonium, zeolite diammonium phosphate is abbreviated as zeolite diammonium, and the abbreviations in the following tables are the same.
As can be seen from tables 8-13, the yield of the wheat with the four diammonium phosphates containing 10-40% of zeolite applied to the corn and the millet is consistent with the yield increasing effect of the wheat with the four diammonium phosphates containing 10-30% of zeolite applied to the wheat with the same amount of pure diammonium phosphate, and the yield is different from the control to a significant extent.
(3) Zeolite field positioning test for improving ammonium phosphate fertilizer efficiency
The test results are shown in tables 14 to 17. Three-year positioning tests show that the yield increasing effect of corn by applying monoammonium phosphate containing 10-30% of zeolite is consistent with that of corn by applying the same amount of pure monoammonium phosphate, the yield increasing rate of corn averagely reaches 32-35.8% in three years, and the yield and the contrast ratio reach a very significant degree. The yield increase of 25.8% was 6.2% -10% higher than that of 25.8% using a lower amount of pure monoammonium phosphate (treatment 3 with the same amount of pure monoammonium phosphate as that added with zeolite 10% -30%), with the difference also reaching a significant degree.
Three-year positioning tests show that the yield increasing effect of corn by using 20-30% of diammonium phosphate containing zeolite is similar to that of pure diammonium phosphate with the same quantity, the yield increasing rate of the corn is averagely 33-38% in three years, and the yield and the contrast ratio are very different. The yield increase rate is 10.5-14.9% higher than that of the pure diammonium phosphate with low dosage (the pure diammonium phosphate quantity of the treatment 3 is the same as that of the pure diammonium phosphate with 20-30% of zeolite).
The three-year experiments described above also demonstrate that the use of zeolite-containing ammonium phosphate results in sustained crop yield increases.
