Abstract
The invention discloses selenium-rich slow release coated urea, which belongs to the field of fertilizers and solves the technical problem of low utilization rate of urea nitrogen in the conventional fertilizer. The selenium-rich slow release coated urea is a particulate matter formed by wrapping fertilizer core in bentonite serving as a covering material by taking cold-soluble polyving akohol as an adhesive, wherein the mass of the bentonite is 2-5 percent of that of the fertilizer core; and the fertilizer core consists of the following components in parts by weight: 15-35 parts of urea, 5-10 parts of antibacterial peptide and 10-20 parts of selenium chelate. According to the selenium-rich slow release coated urea, the absorption and utilization effect of the crops on nitrogen can be obviously improved, the adsorption of plants to the nitrogen and other nutrient elements is enhanced, the utilization rate of the fertilizer is obviously improved and is improved to 30-40 percent, and the amount of the used fertilizer is reduced by 20-33 percent. By using the selenium-rich slow release coated urea, the yield of grain can be increased by 15-30 percent, the yield of vegetables is increased by 20-50 percent, and the yield of economic crops is increased by over 20 percent under the condition of an equal amount of fertilizer.
Description
Technical field
The invention belongs to fertilizer field, be specifically related to a kind of rich selenium release-controlled coated urea.
Background technology
Urea efficiency is high, and longer duration supplies steadily fertilely, does not destroy soil again, is ideal kind comparatively in the present chemical nitrogen fertilizer.The common urea that present industrial agricultural is used is instant fertilizer, and fertilizer efficiency period is short, and the fertilizer nitrogen utilization efficiency is low, and the overall utilization of blood urea nitrogen has only 30%～35%.
Summary of the invention
The present invention will solve the low technical problem of utilization ratio of the blood urea nitrogen in the existing fertilizer; And a kind of rich selenium release-controlled coated urea is provided.
A kind of rich selenium release-controlled coated urea is to be sticker, to be that coating material is with the PM for particulate matter that forms among the fertile core parcel with the wilkinite with cold cut property polyethylene alcohol among the present invention; Said wilkinite is 2%～5% of a fertile core quality, and fertile core comprises 15～35 parts of urea, 5～10 parts of antibacterial peptides and 10～20 parts of chelating selenium by ratio of weight and the number of copies and forms.
Said fertile core also comprises 25～40 parts of diammonium phosphate, 3～10 parts of ferric sulfate and 15～30 parts of calcium sulfate by ratio of weight and the number of copies.
Fertilizer of the present invention utilizes granulating disc to process.Urea, antibacterial peptide and chelating selenium etc. are processed particle, place granulating disc with wilkinite then, spray cold cut property polyethylene alcohol, oven dry obtains rich selenium release-controlled coated urea after the granulation.
Fertilizer according to the invention can effectively prolong the fertilizer efficiency usage period, and the total validity period of fertilizer arrives 180～260 days.Fertilizer of the present invention has extremely strong chelating function to plant desired nutritional composition, and effectively nitrogen, phosphorus, calcium, potassium and trace element supply the plant absorbing utilization in the enrichment soil.
Fertilizer of the present invention can significantly improve crop absorption of nitrogen is utilized effect, and enhancement of plant significantly improves fertilizer utilization ratio to the absorbed dose of nitrogen and other nutritive element, and utilization rate of fertilizer brings up to 30%～40%, reduces fertilizer amount 20%～33%.
Fertilizer of the present invention has the growth that promotes root system, and healthy and strong plant significantly strengthens disease-resistant, drought resisting, the multiple function of precocious resistant to lodging and short.
Use the present invention under the fertilizer condition of equivalent, can make increases in grain production 15%～30%, vegetables raising the output 20%～50%, cash crop increase more than 20%.
