Abstract
The present invention belongs to the field of chemical composite fertilizer technology. The controlled-releasing composite fertilizer specially for tea tree consists of coated urea and composite phosphate-potash fertilizer. The coated urea consists of urea, urease inhibitor, nitration inhibitor and organic coating material, and features the urease inhibitor selected from hydroquinone and tea polyphenol, the nitration inhibitor dicyandiamide and/or thiourea, and the organic coating material polyacrylic resin or polyurethane resin. The chemical composite fertilizer has the N to P2O5 to K2O ratio of 1 to 0.2-0.5 to 0.2-0.5, and has the nutrients essential for tea tree to grow.
Description
[technical field]
The invention belongs to chemically composited fertilizer technology field, be specifically related to a kind of tea tree control release composite fertilizer special.
[background technology]
Controlled-release compound fertilizer is long with its fertilizer efficiency, plant recovery of nutrient is high and use advantages such as safe ready, more and more receives insider's concern.Also be in the experimental study stage substantially in China, at most just small serial production, production cost is higher, and range of application is narrow.As application number be: 96114666.4,96115067.X, 96119508.8,96119494.4 patent application or patent, what describe is the different technical scheme of controlled release nitrogenous fertilizer, promptly adds control-released agent in the production technique of urea or other nitrogenous fertilizer, with release rate and the nitrated conversion that slows down nitrogen.It uses and also only to have satisfied the needs of crop to nitrogen nutrient, has just reduced the release rate of nitrogen with the difference of common nitrogenous fertilizer, has improved the utilization ratio of nitrogen.Application number is: 01107636.4 patent application, a kind of manufacturing and using method of controlled release fertilizer for leaf vegetable and its are disclosed, the content proportioning of the fertile nitrogen of this controlled release, phosphorus, potash fertilizer is specifically disclosed, and the compound method of control-released agent, this controlled release fertilizer is relatively good to the result of use of leafy vegetable, but inapplicable other crop.The overall two aspect shortcomings that exist of existing controlled-release compound fertilizer: (1) production cost height, be the several times of general chemical fertilizer commonly used, very difficult big area is promoted the use of.(2) nutrient release rate is difficult to control to the requirement that meets the Different Crop growth rhythm, and its widespread popularity is restricted.Find at present to be used for the patent application or the disclosed technology report of the controlled-release compound fertilizer of tea tree crop as yet.
[technology contents]
According to the problem of prior art situation and existence, the objective of the invention is to be to provide a kind of plant recovery of nutrient height, fertilizer efficiency long, use safe ready, relative cost is lower; And can obviously improve tea leaf quality, promote the technical scheme of a kind of control release composite fertilizer special of tea growth.
Described tea tree control release composite fertilizer special, form by coated carbamide and phosphorus potassium complex fertilizer, coated carbamide is by urea, urease inhibitors, nitrification inhibitor and organic coated material are formed, it is characterized in that described urease inhibitors is at least quinhydrones, a kind of in the tea-polyphenol, addition is the 0.5-2.5% of coated carbamide, described nitrification inhibitor is at least Dyhard RU 100, a kind of in the thiocarbamide, addition is the 0.5-2.0% of coated carbamide, described coated fertilizer is polypropylene acid or urethane resin, addition is the 2-5% of coated carbamide, nitrogen in the above-mentioned composite fertilizer, phosphorus, the ratio of potash fertilizer is: N: P

2O is 1: 0.2-0.5: 0.2-0.5.
Described tea tree control release composite fertilizer special is characterized in that described urease inhibitors addition is the 1.5-2.0% of coated carbamide.
Described tea tree control release composite fertilizer special is characterized in that described nitrification inhibitor addition is the 1.0-1.5% of coated carbamide.
Described tea tree control release composite fertilizer special is characterized in that described coated fertilizer addition is the 3-4% of coated carbamide.
Described tea tree control release composite fertilizer special is characterized in that described phosphate fertilizer is at least a kind of in phosphamidon, the calcium superphosphate, and described potash fertilizer is at least Repone K, a kind of in the vitriolate of tartar.
Described tea tree control release composite fertilizer special is characterized in that the ratio of described nitrogen, phosphorus, potash fertilizer: N: P
2O
5: K
2O is 1: 0.2-0.3: 0.2-0.3.
Percentage composition that patent application of the present invention is related and ratio are weight percentage and weight ratio.
Tea tree control release composite fertilizer special provided by the invention, proportioning is scientific and reasonable, this fertile rate of release is coordinated mutually with the growth of tea plant demand substantially, and comprised the required basic nutrient of growth of tea plant.Through test, nitrogen utilization efficiency can improve more than 20%, and fertilizer amount can reduce 30%.Simultaneously, controlled the conversion of the hydrolysis of urea and ammonium nitrogen effectively, satisfied tea tree happiness ammonium nitrogen and detested the nutrient demand characteristics of nitric nitrogen, and reduced environmental pollution to nitric nitrogen.Cost only is the 20-50% of external similar fertilizer.And because fertilizer efficiency is long, can reduce fertilizer application frequency, save man-hour, and be beneficial to mechanized.
[embodiment]
Below the invention will be further described by three embodiment.
Prescription 1:
Big grain urea (N46%): 32%; Calcium superphosphate (P
