Abstract:
OBJECTIVETo confirm the amount of fertilizer and the ration of fertilizer.
METHODThrough the experiment of planting Salvia miltiorrhiza in pot and in field were carried out.
RESULTWhen N:P = 1:1, The production was 1.8 times more than the contrast group in plotting experiment, and in field the production of the highest fertilizer plot were 2.5 times more than the contrast and the higher and high fertilizer plot is 2.25 and 1.2 times respective were than those in the contrast group.
CONCLUSIONThe proper ration of nitrogenous fertilizer and phosphorous fertilizer is 1:1. Nitrogen shows negative effects to the accumulation of tanshinon IIA, the more the nitrogen ous fertilizer, The less the content of tanshinon IIA. In contrast, phosphor ous fertilizer shows good effects on the accumulation of tanshinon IIA. Phosphorous fertilizer could alleviate the decline of the content of tanshinon IIA by using nitrogenous fertilizer. The accumulation peak of the tanshinon IIA emerge in the period of 150 d.
