大田作物群体的光合作用测定,目前国内采用的主要方法是气流法和CO_2补偿法。这两种方法都需要把CO_2分析仪、管道系统和电源等设备带入田间,并且为解决光合箱内升温问题,需配备制冷机、空调机等作为降温设备,结构较复杂,造价昂贵,普遍使用存在一定困难。为解决以上问题,我们参考日本和美国的密闭式测法,并加以修改,以
Photosynthesis of field crop populations determination, the current domestic use of the main methods are air flow method and CO 2 compensation method. Both of these methods require the CO 2 analyzer, piping and power supply to be brought into the field. In order to solve the problem of temperature increase in the photosynthetic apparatus, a refrigerator, an air conditioner and the like are required as a cooling device, and the structure is complicated, expensive, and common There are some difficulties in the use. To solve the above problems, we refer to the closed-end test in Japan and the United States, and modify it to
