1.肯尼亚的专家研究出一种细菌接种物.这种细菌接种物可促进豆科作物的固氮过程,提高作物产量.它价格低,效用高,可取代化肥.试验表明:用0.5公斤这种接种物,相当于用50公斤化肥所获得的增产效果,成本仅是化肥的5%.2.肯尼亚的研究者培育出一个改良的马铃薯品种,命名为“肯尼亚塔曼”.这是肯尼亚国家马铃薯研究中心从国际马铃薯中心提供的无性系培育出来的.“肯尼亚塔曼”白皮黄肉,抗晚 1. Kenyan experts have developed a bacterial inoculum that can promote the nitrogen fixation of leguminous crops and increase crop yield. It is low in price and high in utility and can replace fertilizers. The experiment shows that with 0.5 kg of this The inoculum is equivalent to the yield increase achieved with 50 kg of fertilizer at a cost of only 5% of the fertilizer.2 Researchers in Kenya have developed a modified potato variety named “Kenya Taman” which is Kenya The National Potato Center was developed from the clones provided by the International Potato Center. “Kenya Taman ” White-yellow meat, resistant to late
