Abstract:
OBJECTIVETo study the effects of S-3307 spraying time and density on photosynthetic characteristic of Ligusticum chuanxiong.
METHODThe photosynthetic characteristic of L. chuanxiong under different S-3307 spraying time and density was studied by plot cultivation experiment.
RESULTThe content of chlorophyll a and chlorophyll b in leaf increased when the spraying density was 20, 40, 80 mg x L(-1), while the net photosynthetic rate was the maximum. When the spraying density was 160 mg x L(-1), the content of chlorophyll a and chlorophyll as well as net photosynthetic rate were not increased.
CONCLUSIONS-3307 spraying can raise the photosynthetic capacity of L. chuanxiong and promote the form of assimilation products.
