通过定点、定时观测,对线辣椒、小麦共生期间线辣椒冠层所接受的直射光时间、直射光和散射光强度进行了观测,同时对间套和单作下线辣椒病毒病感病株率进行了调查。结果表明:东西走向带型线辣椒所接受的直射光时间几乎为南北走向带型线辣椒接受直射光时间的2倍;在陕西省关中地区,共生期间的线辣椒接受的散射光强度虽然明显低于直射光强度,但在晴天或多云情况下,散射光的强度基本可以满足线辣椒光合需要;线辣椒、小麦间套可以明显降低线辣椒病毒病感病株率。
The direct light time, direct light and scattered light intensity received by peppers and canopy during the symbiosis of peppers and wheat were observed by fixed point and timed observation. At the same time, We conducted a survey. The results showed that the direct light received by the east-west strip-type peppers almost twice as long as the direct-light from the north-south strip-shaped peppers. In the Guanzhong area of Shaanxi Province, the intensity of the scattered light received by the peppers was significantly lower However, in sunny or cloudy conditions, the intensity of scattered light can basically meet the photosynthesis needs of peppers. The peppers and wheat intercrops can significantly reduce the susceptible strain of peppers.
