酸性土壤改良技术领域专利情报分析

Patent analysis of acid soil improvement technology

土壤过度酸化是导致全球土壤退化的主要因素之一,土壤酸化会降低土壤肥力,危害作物生长发育,加重土壤重金属污染等。中国农田土壤酸化问题严重,改良酸性土壤以实现农田可持续发展备受关注。基于incoPat专利数据库对2020年前酸性土壤改良技术领域的专利进行计量学统计,探讨该领域技术研发的现状、应用和趋势。结果表明,中国在该领域专利申请数量整体呈现快速增长的态势,国内申请占全球总申请量的85%。酸性土壤改良技术以综合型改良为主,在改良土壤酸度的同时更加关注土壤养分的缺乏;土壤酸化模拟预测方法、采用土壤酸化改良装置可以提高改良效果,更加高效、环保、多功能的改良技术不断涌现;当前,高校和科研机构的专利转化率较低,企业研发实力尚需加强。酸性土壤改良技术市场前景广阔,应加强新技术、新材料的研发,促进专利技术产业化发展。

Excessive soil acidification is one of the main factors leading to global soil degradation.Soil acidification will reduce soil fertility,harm the growth and development of crops,and increase soil pollution of heavy metals.China’s farmland soil acidification is a serious problem,and improving acidic soils to achieve sustainable farmland development has attracted much attention.Based on the incoPat patent database,conducted metrological statistics on the invention patents in the field of acid soil improvement technology applied before 2020,and discussed the current status of technology research and development,development trends and industrialization in this field.The results showed that the overall number of patent applications in this field in China showed a rapid growth trend,and domestic applications accounted for 85%of the total global applications.The improvement technology is based on comprehensive amendments,which pay more attention to the lack of soil nutrients while improving acidic soil;soil acidification simulation prediction methods and soil acidification improvement devices improve the efficiency of improvement,and more efficient,environmentally friendly,and multi-functional improvement technologies have been developed.The patent conversion rate of universities and scientific research institutions is low,and the R&D strength of enterprises is not high.The acid soil improvement technology has a broad market prospect,and the research and development of new technologies and new materials should be strengthened to promote the industrialization of patented technologies.
