Abstract
The invention provides a preparation method of a fertilizer special for wheat.The fertilizer is dark brown liquid and can be applied in a sprayed or fushing mode.The fertilizer has the advantages that amino acid and microelements are subjected to a sufficient chelation reaction through a chelation catalyst, the defect that waste is caused due to the fact that microelements are in a free state so as to be prone to leaching loss in a traditional compound method is overcome, and the utilization rate of the microelements in the fertilizer is improved through chelation of amino acid and metal ions; a method integrating three-step warming, medium trace element synchronous chelation and standing reaction is adopted in the production process, so that energy consumption is saved, and the production cost is greatly reduced; sediment produced in the production process is removed through a centrifugal filter method, and layering and sedimentation phenomena caused by long-time storage of the product are avoided; experiments verify that the wheat plant height, grain number per spike and thousand seed weight are remarkably improved, the average yield is increased by 6%, and the yield increasing range is remarkable.
Description
Technical field
The preparation method that the present invention relates to a kind of fertilizer, the preparation method of especially a kind of Special fertilizer for wheat, belong to technical field of fertilizer production.
Background technology
Semen Tritici aestivi is one of three big corn, and Semen Tritici aestivi in 2010 is that total output occupies the cereal crops of second in the world, is only second to Semen Maydis.Semen Tritici aestivi, in China's plantation history of existing more than 5000 year, mainly originates in Henan, Shandong, Hebei, Anhui etc. and economizes.Wheat in China is based on winter wheat, from south to north, from Plain to mountain area, and nearly all agriculture district cultivated wheat invariably.The cultivated area of Wheat in China and total output are only second to Oryza sativa L., occupy China's cereal crops second.Semen Tritici aestivi is the staple food of the north of China people, nourishes the important foodstuffs of human body exactly from ancient times.
Fe, Mn, Cu zinc boron molybdenum is 6 kinds of trace element necessary to Growth of Wheat, although consumption is little, if but lack and settle the utilization rate that can directly limit Semen Tritici aestivi N P and K, cause " with fertile many, yield poorly ".Currently, being continuously increased with application quantity of nitrogen phosphorus potassium along with the yield of Semen Tritici aestivi improves constantly, the trace element element taken away from soil every year has substantially exceeded the supply of soil, and soil trace element lacks the limiting factor having become as improving yield of wheat.So, add in conjunction with the wheat growth stage prevention and control of plant diseases, pest control and join trace-element fertilizer, be that a kind of cost is low, instant effect, high efficiency, well stimulation easy to use.
Wheat growth particularly photosynthesis is had the facilitation of uniqueness by aminoacid, and it can increase wheat leaf blade chlorophyll content, improves the activity of enzyme, promotes photosynthesis, and to improving, wheat quality is significant.Semen Tritici aestivi uses amino acid fertilizer can increase the various nutrient elements needed for growth promoter, aggravate the accumulation of dry and from wheat root or leaf portion to the running speed at other positions and quantity, regulate ratio and the poised state of a great number of elements, trace element and various nutrition, thus playing the effect regulating Semen Tritici aestivi normal growth.Aminoacid may also operate as the effect of chelating agent, it is possible to medium trace element generation chelatropic reaction, element needed for Semen Tritici aestivi is produced protective effect, and generates dissolubility absorbed chelate good, easy, thus being conducive to the absorption of wheat plant.
Summary of the invention
The preparation method that the invention provides a kind of Special fertilizer for wheat, purpose is in that to utilize chelating catalyst to make aminoacid and medium trace element carry out abundant chelatropic reaction, and composite a great number of elements N P and K, prepare that a kind of nutrient is comprehensive, fertilizer efficiency persistently, the Special fertilizer for wheat of comprehensive nutrition, to be reached for wheat growth overall process and provide omnidistance nutrition, to ensure the purpose of Semen Tritici aestivi flour quality.
