The experiment on the effect of various concentrations of nutrient solution on sand culture of Salvia miltiorrhiza was carried out. The results show that Salvia miltiorrhiza is a fertilizer tolerant plant. It can grow well and give high yield when the total concentration of nutrient reaches 0.37%.
The symptoms and influence of N, P and K deficiency on the dry matter accumulation and nutrient contents of Jobi were studied with sandy culture. The results have provided scientific basis for rational application of fertilizer.
The experiment revealed that the use of various kinds of fertilizers has apparent effect on the yield of Asparagus cochinchinensis during its growth period. Nitrogen fertilizer and compound fertilizer are suitable for the seeding period, while compound fertilizer, phosphorus and potassium fertilizers are suitable for the period of root forming. The quantity of fertilizer to be used depends on the growing and soil conditions.
