植物生理学作为现代科学的一个领域,在我国已有五十多年的研究历史,它在促进与指导农业生产中正日益显示出越来越重要的作用。国内外农业生产实践充分证明植物生理学同农业关系非常密切。植物生理学和农业是基础理论同应用技术的关系。一、植物生理学可以引起农业的巨大变革十九世纪中期,李比西从植物生理角度创立学说,提出以矿质肥料施入土壤中来代替植物每年从土壤里摄取并消耗掉的营养元素,拟定“归还定律”,提出“最低限度定律”。植物矿质营养学说导致了化肥工业的建立,化肥的广泛应用大大提高了单位面积作物产量。据联合国粮农组织统计,近二十年世 As a field of modern science, plant physiology has more than 50 years of research history in our country. It is playing an increasingly important role in promoting and guiding agricultural production. The practice of agricultural production both at home and abroad fully proves that plant physiology has a very close relationship with agriculture. Plant physiology and agriculture are the basic theory and application of technology. First, the great changes in plant physiology can cause agriculture The mid-nineteenth century, Li Bixi from the point of view of plant physiology to create a doctrine proposed mineral fertilizer applied to the soil instead of plants each year from the soil uptake and consumption of nutrients, the development of “ Return law ”, put forward the“ minimum law. ” The theory of plant mineral nutrition has led to the establishment of the fertilizer industry. The widespread application of fertilizers has greatly increased crop yields per unit area. According to the UN Food and Agriculture Organization statistics, nearly 20 years
