Granulated fertilizer (A) 444.0g that will the be covered swivelling chute of packing into forms rolling condition, is heated to about 70 ℃ by the hot blast granulated fertilizer (A) that will be covered.Then, add in advance and in 100 ℃ of following fused hardened castor oils [she makes by rattan system oil (strain), trade(brand)name: castor-oil plant winterized stearin, fusing point: about 85 ℃] 12.0g, dissolved 2,3,3-triiodo vinyl carbinol [three like oil (strain) system antiseptic-germicide, trade(brand)name: SK-TIAA] 0.20g's contains 2,3, the hardened castor oil of 3-triiodo vinyl carbinol was kept rolling condition at 5 minutes under the heating condition.Then, near the cool to room temperature, obtained with 2,3, the lining granulated fertilizer of the mixture of 3-triiodo vinyl carbinol and hardened castor oil lining (below be designated as lining granulated fertilizer (1).)。
Test example 1 (dissolution test in the water)
In sample bottle, pack into for the lining granulated fertilizer 2.5g (60～80) of examination, add entry 100ml, under 25 ℃, leave standstill to it.Through after the specified time, the water 0.6ml in the sample thief bottle measures urea concentration.Calculate the solubility rate of the urea of the lining granulated fertilizer of confessing examination according to the urea concentration of being measured.
Test example 2 (dissolution test in the soil)
The soil 333.0g of Bingku county is packed in the cup, pack into, mix lightly so that after the fertilizer that be covered do not assemble, cultivate down at 25 ℃ with spatula for the lining granulated fertilizer 2.5g that tries in this.After 14 days, in cup, put into the water of 203ml, under 25 ℃, leave standstill, will all reclaim for the lining granulated fertilizer of examination after the specified time, measure the remaining quantity of urea in the lining granulated fertilizer that reclaims.According to the remaining quantity of the urea of measuring, calculate the solubility rate of the urea of the lining granulated fertilizer of confessing examination.Have, data will be will drop into day in the soil for the lining granulated fertilizer of examination as the 0th day again.
With the differential of the solubility rate of dissolution test in the solubility rate of dissolution test in the soil after the specified time and the water in table 1.

[utilizability on the industry]
Coating granular fertilizer of the present invention also can suppress the decomposition of the coating that edaphon etc. causes when trying in soil, suppress with water in the difference of stripping pattern. Therefore, coating granular fertilizer of the present invention has the excellent properties of the generation that the stripping pattern that suppresses to be caused by the difference of using scene changes.
