How do you manage Salvia miltiorrhiza well during cultivation? Please provide guidance.
Salvia miltiorrhiza cultivation management is as follows:
1. Intertillage and weeding. Generally carried out 3 times, the first in May, when the seedlings are about 15 cm tall; the second in June; the third in August.
2. Timely topdressing. Topdressing is carried out together with intertillage and weeding. Per mu, apply 2000 kg of fully decomposed manure water, 15 kg of superphosphate, or 50 kg of cake fertilizer. In particular, the third topdressing should be applied heavily, because during this period topdressing increasingly promotes root growth and achieves high yield.
3. Timely drainage and irrigation. Salvia miltiorrhiza is a fleshy-root plant and is afraid of waterlogging. Therefore, drainage ditches should be cleared regularly to remove accumulated water and prevent waterlogging. The emergence stage and seedling stage have a relatively large water requirement, and in dry weather it should be watered in time.
4. Flower removal. Except for seed-production plots, flower stems must be cut off in batches to inhibit reproductive growth and promote root vegetative growth. This is another important measure for increasing Salvia miltiorrhiza yield.
