Abstract
The invention relates to the field of chemical fertilizers, in particular to a compound controlled-release fertilizer special for spring corns and a production method of the compound controlled-release fertilizer. The compound controlled-release fertilizer special for spring corns is composed of the following components in parts by weight: 300-500 parts of nitrogenous fertilizer, 100-170 parts of phosphate fertilizer, 120-235 parts of potassic fertilizer, and 3-15 parts of a slow controlled release long-acting agent. The nutrient supply, the efficiency and the time of the compound controlled-release fertilizer special for spring corns are synchronized with the crop growth requirements, the special proportion of nitrogen, phosphorus and potassium of the special fertilizer in the soil for crops can be enhanced and the formula balanced fertilizing is achieved.
Description
Technical field
The present invention relates to chemical fertilizer field, specifically a kind of compound controlled release spring maize special fertilizer and production method thereof.
Background technology
Release/controlled release dedicated fertilizer is to be granular urea by adopt nitrogen in common special fertilizer, peptide urea, a kind of fertilizer that can slow down or control nitrogen nutrient releasing speed in soil that sulfur-coated urea and controlled release long-acting agent compound technology are produced, its advantage is that the utilization ratio of nutrient is high, compared with common fertilizer, compare effect of increasing production obvious, the amount of application of fertilizer is few, extensively promoted the use of, but, in prior art, seldom have according to the compound controlled release special fertilizer to many technical combinations of nutritional needs in crop growth period, only monotechnics release/controlled release are fertile, because price height is also only for ornamental plants such as flower plants and nursery stocks, still not for common field crop, especially in corn growing season, nutritional needs feature being carried out the control release composite fertilizer special of nutrient release.
Summary of the invention
The object of the invention is to provide a kind of compound controlled release spring maize special fertilizer and production method thereof.
For achieving the above object, the technical solution used in the present invention is:
A kind of compound controlled release spring maize special fertilizer, compound controlled release spring maize special fertilizer is comprised of nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and controlled release long-acting agent, count by weight 300-500 part nitrogenous fertilizer, 100-170 part phosphate fertilizer, 120-235 part potash fertilizer and the agent of 3-15 umber controlled release long-acting.
Described meter by weight, nitrogenous fertilizer is peptide urea, 100-150 umber sulfur-coated urea and the 100-300 umber granular urea of 100-240 umber; Described phosphate fertilizer is diammonium phosphate; Described potash fertilizer is Repone K.
The preparation method of compound controlled release spring maize special fertilizer, counts by weight, and 300-500 part nitrogenous fertilizer, 100-170 part phosphate fertilizer, 120-235 part potash fertilizer and the agent of 3-15 umber controlled release long-acting mix, and obtain compound controlled release spring maize special fertilizer after mixing.
Described meter by weight, nitrogenous fertilizer is peptide urea, 100-150 umber sulfur-coated urea and the 100-300 umber granular urea of 100-240 umber; Described phosphate fertilizer is diammonium phosphate; Described potash fertilizer is Repone K.Described compound controlled release spring maize special fertilizer is executed once and is applied as base, and sowing amount is 30-50 kg/acre.
The present invention has advantages of: the effect of the nutrient supply amount of special fertilizer of the present invention, intensity, time and plant growth demand synchronised, stable private fertilizer is in the special-purpose ratio of Nitrogen In Soils phosphorus potassium three elements crop, and multiple controlled-release technology has been realized special fertilizer balance fertilizing.Simultaneously, owing to having adopted the relatively low raw material of price, by specific proportioning, make corn special controlled-release composite fertilizer, ensure in corn growing season the demand intensity of nitrogen and supply, guarantee that nitrogen nutrition release and phosphorus potassium supply ratio are relatively stable, reaching corn growth does not take off in earlier stage few, mid-term, ripening stage process is moderate, reach straw staygreen, improved utilization rate of fertilizer, adopt the Controlled Release Fertilizer of other release/controlled release technology significantly to reduce production cost, promoted further applying of this technology; In the present invention, due to adopted compound control nitrogen rate of decomposition technology effective the release of controlled release nitrogen in early stage, Spring-maize Growth corn seeding to jointing stage nitrogen requirement is mainly derived from nutrition in seed, during this, nitrogen requirement only accounts for total nitrogen requirement 3-5%, now the soil moisture is relatively low, and nitrogen transformation is substantially in lower level.When corn growth enters typhon mouth phase to the filling stage, there are two peak periods in corn growth demand nutrient, and this phase demand nutrient is that maximum phase nitrogen requirement accounts for the 75-84% of whole breeding time, at this moment supplies the output that nutrient levels determines corn.Compound controlled release special fertilizer of the present invention can offer the required enough amount of nutrients of corn and intensity in the bimodal peak period of nutrition when Spring-maize Growth, be in compound controlled release special fertilizer, to regulate and control that nitrogen function realizes fertilizer releasing period and the Spring-maize Growth bimodal phase of specific nutrition in period is overlapping, and then make spring maize better absorb nutrient, extending fertilizer efficiency exempts to topdress: extend fertilizer efficiency period 110 days～120 days, exempt to topdress the time of infertility with a fertile bottom application.Fertilizer synergistic joint is fertile: improve utilization rate of nitrogen fertilizer 11%～19%, improve composite fertilizer's nutrient comprehensive utilization ratio 17%～25%, save fertilizer amount 10%～20%.Improve plant growth characteristic: extend the chlorophyll life-span, strengthen photosynthesis, promote root growth, strengthen the anti-environment capacity of coercing.
