中国科学院从“八五”期间科技成果中筛选出10项农业新技术向全国推广。这10项适用技术是: 一、长效碳酸氢铵长效碳酸氢铵是中科院沈阳应用生态所研制的一种良性新氮肥,与普通碳铵相比,其氮素利用率提高10%,肥效期由35天延长到110天,可增产13%左右。二、涂层尿素涂层尿素是一种新型尿素氮肥,与普通尿素相比,氮素利用率提高6～8%,可增产10～13%。
Chinese Academy of Sciences screened 10 new agricultural technologies for nationwide promotion from scientific and technological achievements during the “1985” period. The 10 applicable technologies are: First, the long-acting ammonium bicarbonate Long-acting ammonium bicarbonate is a kind of benign new nitrogen fertilizer developed by Shenyang Institute of Applied Ecology, Chinese Academy of Sciences. Compared with common ammonium bicarbonate, its nitrogen utilization rate is increased by 10% The period from 35 days to 110 days, can increase about 13%. Second, coated urea coating urea is a new type of urea nitrogen fertilizer, compared with ordinary urea, nitrogen utilization increased 6 ~ 8%, 10 ~ 13% increase.
