Description
Technical field
The invention belongs to technical field of agricultural fertilizers, be specifically related to gynaminic acid whitewashing composite fertilizer and preparation method thereof.
Background technology
China is large agricultural country, and nearly 5,000 ten thousand tons of at present annual applying quantity of chemical fertilizer, account for the more than 1/4th of global chemical fertilizer usage quantity, rank first in the world.But, because people blindly use in a large number NPK fertilizers in conventional fertilizers, make the nutrient accumulation in soil, cause fertilizer waste, produce serious environmental problem.It is reported, the utilization ratio of China's nitrogenous fertilizer is for being less than 50%, phosphate fertilizer utilization efficiency is less than 20%, potassium utilization rate is less than 60%, this is mainly because crop is different to the demand of nutrient in the Different Nutrition stage, and the release of the nutrient of existing fertilizer is often asynchronous to the absorption of nutrient with crop, make superfluous nutrient by modes such as volatilizing, drench, enter water body and atmosphere in soil.
Along with a large amount of uses of chemical fertilizer, the continuous reduction of its utilization ratio has been well known fact.This explanation, it is limited only depending on a large amount of application fertilizers to improve crop yield, also has still more a series of problems such as contaminate environment.Various countries scientist is making great efforts explore to improve chemical fertilizer utilization ratio always and is reaching balance fertilizing, the rational application of fertilizer to overcome the approach of its drawback for this reason.Microbial fertilizer has original effect in solution this respect problem.So, according to China's crop species and edaphic condition, adopt suitable microbial fertilizer and chemical fertilizer compounding application, can guarantee volume increase, reduced again fertilizer application amount, reduce costs, can also improve soil and crop quality simultaneously, reduce and pollute.
Be rich in organic humic acids and be improved soil physical and chemical property, regulate soil acidity or alkalinity, promote the activity of microorganism in soil, increase the activity of soil enzyme, make loosing soil, constantly regulate the soil water, gas, fertile, the situations such as heat, promote plant root system development healthy growth, strengthen the not people conversion rate of organic and inorganic fertilizer in soil, increase plant chlorophyll, improve photosynthesis of plant, can effectively improve the cold-resistant of plant, drought resisting, the degeneration-resistant function such as disease and insect resistance, prevent the soil compaction that soil causes because using excessive inorganic fertilizer, Desertification and contaminate environment, effectively improve crop yield and improve the advantages such as product quality.
How to obtain that fertilizer efficiency is lasting, the composite fertilizer of fixed nitrogen water conservation is prior art technical problem urgently to be resolved hurrily.
Summary of the invention
The object of this invention is to provide a gynaminic acid whitewashing composite fertilizer, this propylhomoserin whitewashing composite fertilizer can improve the output of farm crop effectively, and fixed nitrogen water conservation effect is better.
The object of the invention is to be achieved through the following technical solutions: a gynaminic acid whitewashing composite fertilizer, it is prepared from accordance with the following steps:
(1) slip is produced: sal enixum is put into hopper, the water that interpolation accounts for sal enixum 1/3rd weight stirs, pump carries out neutralization reaction with liquefied ammonia to tubular reactor subsequently, then squeeze in geosyncline, in geosyncline, add urea, monoammonium phosphate, humic acids, magnesium powder and calcium powder to stir and obtain slurry, wherein the amount of substance ratio of sal enixum and liquefied ammonia is 1:1.1, and the mass ratio of sal enixum, urea, monoammonium phosphate, humic acids, magnesium powder and calcium powder is 10:3:2:2:1:1;
(2) configuration diluted acid: first 98% the vitriol oil is joined in dilution trap, slowly add water to obtain diluted acid in whipping process, wherein the mass ratio of 98% the vitriol oil and water is 2:1;
(3) propylhomoserin spray granulating: slurry prepared by (1) is driven in granulation cylinder by volume pump, sprays into diluted acid prepared by liquefied ammonia and step (2) simultaneously and carries out granulation and oven dry, then adds microbial inoculum, and stirrer stirs, and obtains; Wherein, the mass ratio of slurry, liquefied ammonia, diluted acid and microbial inoculum is 100:3:2:1.
Microbial inoculum of the present invention comprises the raw material of following weight parts: 3 parts of subtilises (Bacillus subtilis) CGMCC No:0954(CN1554744), 2 parts of bacillus megaterium (Bacillus megatherium) CGMCC No:2267 (CN101215532), 2 parts of azotobacter chroococcums (Azotobacter chroococcum) ATCC4412(Production of exocellular polysaccharide by Azotobacter chroococcum. Appl Biochem Biotechnol., 1991 Sep, 30 (3): 273-84.),
The cultivation of subtilis or bacillus megaterium: subtilis or bacillus megaterium are seeded in first respectively on beef-protein medium, 30 ℃, making primary inclined plane cultivates, then be inoculated into and in triangular flask, do vibration secondary liquid culture, then proceed to liquid fermentation tank and do three grades of liquid culture, finally be inoculated into and on solid medium, make level Four and cultivate, reach 1.0 * 10 to viable count in product
8individual/gram.
The cultivation of azotobacter chroococcum: azotobacter chroococcum is inoculated on agar slant culture-medium, 32 ℃ of next stage slant culture, then secondary seed cultivation, mixing fermentation culture to viable count reach 1.0 * 10
8individual/gram.

Mt．Mountain town Ipomoea batatas is planted and cultivates experiment field is to carry out in sandstone and earth yellow soil half-and-half, and twice repetition, 4 Processing Test communities are established in test.Group 1: Common compound fertilizer (16-22-7); Group 2: according to the embodiment of the present invention 1 preparation method, but do not add microbial inoculum, humic acids, calcium powder and magnesium powder; Group 3: according to the embodiment of the present invention 1 preparation method, but do not add microbial inoculum; Group 4: the composite fertilizer of the embodiment of the present invention 1 preparation.Each test processing community is mu fertilising 45Kg all, and each community area is 0.2 mu, and in community, rate of fertilizer application is 9Kg, and plantation on June 1st, 2011 was dug to obtain in then and gathered on November 5.In above-mentioned four experiment communities, its contrast output of Sweet Potato Crops is as follows:
The yield comparison of each treatment group of table 2 Ipomoea batatas growing area
| ? | Test site output (Kg) | Per mu yield (Kg) | Mu fertilising price (unit) | Mu income (unit) |
| 1 | 390 | 1950 | 135 | 1560 |
| 2 | 451 | 2255 | 144 | 1804 |
