Soil water is an important link in the transformation of the “five waters”, which determines the growth and production of crops. Mastering the scientific infiltration law is a key link to promote agricultural development. Based on the existing research results, this paper systematically summarizes the basic theories, test methods, influencing factors, simulation equations, prediction models and other results of soil water infiltration research at home and abroad so far, and discusses the future research development direction.
Although traditional industries are commonly dominated by numerous SMEs focused on their respective domestic markets, the Japanese tea industry experienced the emergence and rapid growth of large enterprises in the 1990s. This article analyzes the strategy that enabled such a change, focusing on the most important Japanese tea producer, ITO EN, which developed bottled green tea in 1985. Based on an approach of business history and industry studies, the article argues that the shift in the 1990s was made possible by the transformation of the true nature of the tea industry in going from a commodity business to a branded consumer-goods business.
