随着科技研究的深入与科研领域的拓宽,无土栽培技术的推广和利用,无疑给21世纪的种植业开辟了一条新途径,引入一场新的绿色革命。食物是人类生存的必备条件,“二战”以来,各国人口迅猛增长了50%。据有关专家估算,这段时期全球每年产量平均增长1倍才能满足需求,其中,种植业发挥了巨大作用,直接关系到人类的温饱问题。农业科学课题也不断在开发,比如“科学种田”、“改革食物结构”、“新品种的培育”、“宇宙外空”等,但都有各自不同
With the deepening of scientific and technological research and the expansion of scientific research, the popularization and utilization of soilless cultivation technology undoubtedly opened up a new way for the planting industry in the 21st century and introduced a new green revolution. Food is a necessary condition for the survival of mankind. Since the “World War II”, the population of all countries has risen sharply by 50%. According to the estimation of relevant experts, the average annual growth of output in the world during this period can twice meet the demand. Among them, the planting industry has played a great role and has a direct bearing on the issue of food and clothing for humanity. The topics of agricultural science are also constantly under development, such as “scientific farming”, “reform of food structure”, “cultivation of new varieties”, “outer space of the universe”, etc., but each has its own difference
