全球石灰氮总产量不足50万吨，可市场总需求量在60万吨以上，全球双氰胺年需求量为8－10万吨，预计到2010年将增加到12－14万吨，可世界双氰胺的产能不足8万吨。

The dormant bud of apple variety Gala was smeared with potassium nitrate at 1%, 3%, 5%, 7% and 9%, and the dormant bud of grape variety Jufeng was smeared with calcium cyanamide diluted at 2,5 and 8 times (weight ratio of calcium cyanamide to water was 1:2). The effects of potassium nitrate and calcium cyanamide with different concn. on breaking natural dormancy of fruit tree were studied.

方法用浓度为1%、3%、5%、7%和9%的硝酸钾涂抹苹果品种嘎拉的休眠芽，用浓度为2倍液（石灰氮与水的重量比为1：2，下同）5、倍液和8倍液的石灰氮涂抹葡萄品种巨峰的休眠芽，研究不同浓度的硝酸钾、石灰氮打破果树自然休眠的效果。

Both CaCN2 and urea inhibited the chlamydospore germination, mycelial growth and sporulation of the pathogen, but CaCN2 by using at the rates of 0.5 and 1.0%, had two inhibition zones for chlamydospore germination with time while urea had only one. Calcium cyanamide was also more effective on reducing mycelial growth and sporulation of the pathogen than urea did. Therefore, the suppression of pea wilt might be due to fungicidal effect of the intermediate products including hydrogen cyanamide and urea from calcium cyanamide.
