由云南农业大学植物病理重点实验室完成的“植物抗霜剂研制及应用研究”课题,5月7日在昆明通过省科技厅组织的专家鉴定。霜冻害是该省突出的气象灾害。严重霜冻害平均每3年一次。重灾年份受害面积达100万亩,一般年份约有10万亩受冻,个别年份呈毁灭性灾害。由张世珧教授主持的该项研究摸清了该省冰核活性细菌种类及种群动态变化规律,丰富了霜冻害形成的机理,为研究和防御农作物霜冻害及冰核细菌的开发利用提出了全面、系统的科学依
By the Yunnan Agricultural University, Key Laboratory of Plant Pathology completed “plant anti-frost research and application of ” subject, on May 7 in Kunming by the Provincial Science and Technology Agency experts identified. Frost damage is a prominent meteorological disaster in the province. Serious frost damage every 3 years on average. Victims of the hardest year hit 1000000 mus, the general year about 100000 acres of frost, individual years was devastating disaster. The study, led by Professor Zhang Shifang, clarified the rules of species and population dynamics of active bacteria in ice nuclei of the province, enriched the mechanism of frost damage and provided a comprehensive and scientific basis for the research and defense of crop frost damage and the development and utilization of ice nucleating bacteria. The system of science by
