论文部分内容阅读
1985年作者在英国诺丁汉大学农学院进修环境物理时参加了Monteith教授为首的热带半干旱地区作物小气候研究计划。试验是在发芽温床、人工气候箱(风洞)和控制环境温室内进行的。虽然这一年是以高粱为对象的基础性研究,但许多研究结果所揭示的原理对于其它作物也是适用的,现将我所参加承担的部分工作怍一初步总结汇报。一、热当量时间与高粱发芽速率的关系
In 1985, when studying environmental physics at Nottingham University Agronomy College, the author participated in a research program on crop microclimates in tropical and semi-arid areas led by Professor Monteith. The experiment was conducted in germination hotbed, artificial climate chamber (wind tunnel) and controlled environment greenhouse. Although this year is a basic research focusing on sorghum, the principles revealed by many research findings are also applicable to other crops. Some of the tasks that I have taken part in are initially summarized and reported. First, the heat equivalent time and sorghum germination rate
