Abstract
The invention relates to a corn special controlled-release fertilizer and a preparation method thereof. The controlled-release fertilizer comprises the components in parts by weight: 100-240 parts of polypeptide urea, 100-150 parts of sulfur coated urea, 100-300 parts of large granular urea, 100-170 parts of diammonium phosphate, 120-235 parts of potassium chloride, 8-10 parts of zinc sulfate, 80-100 parts of modified starch, 30-50 parts of linseed oil, 40-60 parts of rosin resin, and 110-150 parts of bentonite. The controlled-release fertilizer is reasonable in component collocation, all nitrogen fertilizers, phosphate fertilizers, potash fertilizers, trace elements and beneficial biological bacteria meeting the fertilizer requiring demand of all growing and development seasons of corn are combined together and are applied in soil before sowing, topdressing is no longer needed afterwards, the quality of fertilizer application can be guaranteed, the effect of fertilizer application is improved, inconvenience brought by midsummer high-temperature topdressing is excused, the labor intensity is reduced, and labor employment is saved; the controlled-release fertilizer can slow down the release rate of fertilizer nutrients, improves the nutrient utilization rate, reduces the loss of the fertilizer, relieves the environmental pressure brought by the fertilizer, and has good ecological environment benefits.
Description
Technical field
Agricultural fertilizer technical field of the present invention, is specifically related to a kind of corn-specific controlled-release fertilizer material and preparation method thereof.
Background technology
Fertilizer is the grain of crop, wants to obtain higher output, and sufficient fertilizer must be had to ensure, corn is no exception, and experiment shows, often produces the corn of double centner, needs absorption nitrogen 2-3 kilogram, Vanadium Pentoxide in FLAKES 1-2 kilogram, potassium oxide 1.5-3 kilogram.Corn is also different to the requirement ratio of nutrient in different periods of growing: tri-leaf period, this period, the demand to nutrient was less to the jointing stage, but obtains the basis of high yield; Jointing stage is to heading stage.This phase is the important period that corn ear is formed, and is also the period that nutrient demand amount is the highest, and the nitrogen that this period absorbs accounts for 1/3 of whole breeding time, and phosphorus accounts for 1/2, and potassium accounts for 2/3, and this nutrition supply sufficient phase, can make that milpa is tall and big, stem stalk is sturdy, big panicle many grains per panicle; Full heading time, this phase plant strain growth terminates substantially, and the consumption of nitrogen accounts for the nitrogen 1/5 of whole breeding time, phosphorus accounts for 1/5, potassium accounts for 1/3; Grouting is to the ripening stage, and now the fertilizer requirement of corn increases sharply again, and to form protein, starch and the fat in seed, the nitrogen that this period absorbs accounts for 1/2 of whole breeding time, and phosphorus accounts for 1/3.Zea high yield likes fertile crop, in normal growth growth course, enough organic matters, nitrogen, phosphorus, the large Meso-and micro-nutrients such as major element and calcium, magnesium, sulphur, manganese, zinc, iron of potassium three must be absorbed, especially calcium, magnesium, sulphur, the most manifest symptom of corn calcium deficiency is that the blade tip of blade is inter-adhesive, and leaf can not normal extension; During corn magnesium deficiency many on the Lao Ye of base portion first reveal any symptoms, there is faint yellow striped between vein, after become white, but vein is always in green; Classical symptom during corn a lack of sulfur is spire chlorosis.Therefore will make corn with high yield high-quality, must adopt Special basal fertilizer, product of the present invention is according to the N and P uptake character of corn, and in conjunction with Content of Soil Component, scientific formula forms, and fully can meet the demand of growing in corn each period.This product uses biodegradable Intelligent controlled release fertiliser granulates, the fertilizer efficiency time is long, organic and micronutrient levels enriches, be easy to corn root absorb, make after using that maize root system flourishing stalk is healthy and strong, flourishing, leaf look dark green, corn kernel is full, thousand seed weight increase, surface luster be good, corn yield and quality can be significantly improved, and disease-resistant, drought-resistant ability is strong.
Summary of the invention
The present invention is in order to solve the problem, and propose a kind of corn-specific controlled-release fertilizer material and preparation method thereof, the utilization rate of fertilizer obtained is high, and can meet the corn whole breeding season need fertile requirement.
The present invention in order to the taked technical scheme that solves the problem is: a kind of corn-specific controlled-release fertilizer material: comprise the peptide urea of 100-240 part, the sulfur-coated urea of 100-150 part, the granular urea of 100-300 part, the diammonium phosphate of 100-170 part, the Repone K of 120-235 part, the zinc sulfate of 8-10 part, the treated starch of 80-100 part, 30-50 part oleum lini, 40-60 part Gum Rosin and 110-150 part wilkinite by weight.
The preparation method of above-mentioned corn-specific controlled-release fertilizer material, be specially: the peptide urea getting 100-240 part by weight, the sulfur-coated urea of 100-150 part, the granular urea of 100-300 part, the diammonium phosphate of 100-170 part, the Repone K of 120-235 part, the zinc sulfate of 8-10 part, the treated starch of 80-100 part, 30-50 part oleum lini, 40-60 part Gum Rosin and 110-150 part wilkinite, first by peptide urea, sulfur-coated urea, granular urea, diammonium phosphate, Repone K and zinc sulfate mixing, powder is obtained after stirring, then water is added, powder part is dissolved, then treated starch is added, stir and be heated to boiling, add wilkinite again, continue to stir, finally add the Gum Rosin melted in advance, heat evaporate to dryness while stirring, be dried to fertilizer moisture below 10%, granulation obtains release and release control fertilizer.
beneficial effect
Release and release control fertilizer of the present invention, component collocation rationally, apply in soil by what meet that the corn whole breeding season needs fertile whole nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, trace element and the beneficial organism bacterium required to combine prior to seeding, no longer topdress later, fertilising quality can be ensured, improve fertilization effect, eliminate and to be topdressed the inconvenience brought by summer High Temperature, reduce labor intensity, save labor; And release and release control fertilizer of the present invention can slow down fertilizer nutrient release rate, improve plant recovery of nutrient, reduce fertilizer loss, alleviate the environmental stress applying fertilizer and bring, there is good ecological environment benefit.
