尿素為速效氮肥，施入土壤后很快溶解，其肥效短，利用率低。而本產品是以尿素為核心，以單質硫磺為包膜層。硫不僅是植物必須的中量元素，而且是很好的堿性土壤改良劑（北方許多高爾夫球場在建造種草前常用硫磺粉進行改良）。該產品不僅能使氮肥控制釋放，而且可提供植物必須的硫元素，同時還可降低土壤的PH值，解決了草成坪后使用硫磺粉的不便。北方或沿海偏堿性土壤使用效果更佳。

特點：氮肥緩效，補充硫肥，降低土壤PH值，無污染。

用量：均勻撒施，20-40g/m2。

規(guī)格：

Urea has the characters of fast release and low efficiency. The product is manufacture by coating urea with sulphur. Sulphur is important secondary element, and can regulate the alkaline soil. So the product can not only make urea slow release, but also make the soil pH lower. It is more effective to be used in alkaline soil especially short of sulphur.

Characters：slow release，contain sulphur，reduce pH，environment friendly.

Recommendation：spread and well distributed, 20-40g/m2.
