Abstract
The invention relates to spring maize cultivation, in particular to a dedicated fertilizer for producing green corn and a preparation and an application method thereof.The fertilizer is composed of urine-based nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, medium elements and trace elements; in the preparation method, the solid raw materials with a grain size of 1.5-4.5mm are selected; then the medium elements are added to humic acid or humic acid salt accounting for 60-100% of the mass percent of the medium elements to be mixed; afterwards, trace elements are added and mixed with the mixture, cementing agent is used for pelleting and producing solid raw materials with a grain size of 1.5-4.5mm for standby use; finally, the medium elements and trace elements mixed for pelleting are uniformly mixed with the urine-based nitrogenous fertilizer, phosphate fertilizer and potash fertilizer.The dedicated corn fertilizer is applied to the corn spring sowing as base fertilizer at one time and no after manuring is not needed.The use level of the urea-based nitrogenous fertilizer in the fertilizer of the invention proportion of the urea-based nitrogenous fertilizer in different release periods are set with proportion of the urea-based nitrogenous fertilizer in different release periods according to fertilizer-demanding characteristics on the nitrogenous fertilizer by the corn in different growth periods to form 4-level supply speed of the fertilizer nitrogen, thus remarkably controlling loss of nitrogenous fertilizer.
Description
Technical field
The present invention relates to be used for the spring maize cultivation and production, specifically a kind of dedicated fertilizer for producing green corn and preparation and application process.
Background technology
The common fertilizer fertilizer efficiency period is short, the nutrient proportioning is unreasonable, and nutrient supply is science not, and is more unbalanced, and particularly nitrogenous fertilizer contradiction is more outstanding.The overall utilization ratio of nitrogen has only 30～35% at present, loss such as the leaching loss of nitrogen, volatilization, rainwash is more, the economic benefit that fertilizer applies is lower, cause the huge waste of resource and the increase of agriculture production cost, produce the pollution in underground water and soil face source simultaneously, cause the eutrophication of greenhouse gases effect and water body, make the deterioration of the ecological environment.Fertilizer use in a large number and low utilization ratio descends quality of agricultural product.Concerning spring maize production cultivation, the common fertilizer fertilizer efficiency period is short, nutrient in the fertilizer, particularly nitrogen nutrient discharges with the corn different growth stage inconsistent to nutrient demand, because the concentrated release of nutrient or the release ratio of nutrient are inharmonious, cause utilization rate of fertilizer low, the corn growth environment is produced the nutrient stress effect, do not need to discharge under a large amount of nutrient situations a large amount of nutrients in soil at corn, and when needing nutrient in a large number, corn do not have enough nutrient supplies, therefore corn growth is produced the nutrient stress effect, thereby have a strong impact on the corn kernel quality and pollute agroecological environment.Along with people increase the attention degree of food safety, the demand of green agricultural product is constantly increased, the importance of dedicated fertilizer for producing green corn development that therefore meets the green food requirement is particularly outstanding, and the present invention develops under this background just.Significantly improve particularly utilization rate of nitrogen fertilizer of utilization rate of fertilizer.The invention of this kind dedicated fertilizer filled up spring maize producing region for a long time particularly the Saut band do not produce the dedicated fertilizer of green corn, will greatly promote the green corn production of spring maize district, produce the corn product that meets the green food requirement.
Summary of the invention
The object of the present invention is to provide a kind of Maize Production dedicated fertilizer and the preparation and application process that can effectively improve corn yield and quality.
For achieving the above object, the technical solution adopted in the present invention is as follows:
Dedicated fertilizer for producing green corn, mainly form by N, P, K, fertilizer is made up of the basic nitrogenous fertilizer of urine, phosphate fertilizer, potash fertilizer, moderate-element and trace element, wherein urinate basic nitrogenous fertilizer in the urea pure nitrogen level, by the urea of the common granular urea that accounts for urea pure nitrogen level 2-5%, the slow-release carbamide or the peptide urea that account for urea pure nitrogen level 8-15%, the high molecular polymer (resin) of 45-75 days release periods that accounts for urea pure nitrogen level 30-50% or sulphur dressing (film) with account for the polymkeric substance of 75-110 days release periods of urea pure nitrogen level 40-50% or the urea of sulphur dressing (film) is formed; Phosphate fertilizer is the 40-75% of pure nitrogen level in the basic nitrogenous fertilizer of urine; Potash fertilizer is the 45-100% of pure nitrogen level in the basic nitrogenous fertilizer of urine; Moderate-element is to account for the calcium of pure nitrogen level 15-35% in the basic nitrogenous fertilizer of urine and the magnesium of 10-30%; Trace element is the iron that accounts for pure nitrogen level 2-6% in the basic nitrogenous fertilizer of urine, the copper of 1-4%, the manganese of 1-4%, the zinc of 1-3%, the boron of 0.5-1%, the molybdenum of 0.05-1%.
