Guizhou Province is located in the low latitude plateau mountainous area, and agricultural production plays a dominant role in the national economic construction. In the analysis of previous agricultural climate resources, the analysis of photosynthetically active radiation was less involved. Practical applications mostly accounted for 50% of the total radiation for rough planning. The estimation, but the analysis of the photosynthetically active radiation on the slope is almost blank. Therefore, it is necessary to comprehensively study the temporal and spatial distribution characteristics of photosynthetically active radiation resources in our province. Photosynthetic active radiometers have attempted to do some preliminary work in this respect, providing science for the province to fully and reasonably use agricultural climate resources in agricultural production. in accordance with.
The distribution of photosynthetically active radiation on hillside slopes is the first time in our province. It is feasible and effective to calculate the total radiation of slope and then recalculate the photosynthetically active radiation on the slope through photosynthetic active radiation meter, and it is of great significance to fully and reasonably use the climate resources in practical work.
In our province, many crops are planted on slopes in different orientations, and the photosynthetically active radiation on slopes and slopes varies greatly. Therefore, in practical applications, it is not possible to simply analyze the photosynthetically active radiation in the water level, and it is necessary to consider the effects of slope direction and slope.
Photosynthetically active radiometric measurements showed that the temporal and spatial changes of photosynthetically active radiation were significant, which also reflected the climate differences across the province. In general, the spatial distribution of photosynthetically active radiation is consistent with the total radiation distribution. The high value areas are located in the western part of the province, and the low value areas are located in the southeast and northwest parts of the province. The regional distribution of photosynthetically active radiation differs significantly in winter and summer. small.
