密植作物的丰产栽培实践表明,为夺取每亩千斤左右的高产,其主要矛盾是发展群体结构引起田间通风透光不良,造成抽穗后的倒伏问题。因此,研究密植作物群体内的光分布规律和确定农田光条件的适宜指标,对创造合理的群体结构,以充分地利用光照条件有重要意义,同时也给农田小气候观测和服务方法
The practice of intensive cultivation of densely-cropped crops shows that in order to seize the high output of about one kilogram per mu, the main contradiction is that the development of population structure causes poor ventilation and light in the field and causes the problem of lodging after heading. Therefore, it is of great significance to study the law of light distribution in densely populated crop populations and to determine the appropriate index of light conditions in farmland to make reasonable use of the light conditions, and also to provide microclimate observation and service methods
