What kind of fertilizer is good for salvia miltiorrhiza base fertilizer (base fertilizer application method)

Effect of Salvia miltiorrhiza base fertilizer

Salvia miltiorrhiza is a deep-rooted crop that can absorb water and nutrients from deep in the soil. Therefore, it does not have strict requirements on water and fertilizer during the maintenance period. As long as the soil is moist, you can water it less. As long as you choose fertile farmland and apply enough base fertilizer when renovating the soil, there is no need to apply fertilizer during the subsequent growth period.

Organic fertilizer can be chosen as the base fertilizer for Salvia miltiorrhiza, and it must be fully decomposed. Do not use raw fertilizer directly, as it will cause great damage to the roots.

How to apply salvia miltiorrhiza base fertilizer

Salvia miltiorrhiza base fertilizer can be mixed with potassium sulfate ternary compound fertilizer, biological organic fertilizer, decomposed soil fertilizer, and seaweed essence powder. Topdressing starts from flowering and fruiting, once every 10 to 15 days. It is recommended to use equal amounts of ternary water-soluble fertilizer and biological bacterial fertilizer for flushing. Amino acid foliar fertilizer plus potassium dihydrogen phosphate can also be sprayed on the leaves, once every 10 to 15 days.

How to apply fertilizer to Salvia miltiorrhiza

Salvia miltiorrhiza is topdressed twice. The first topdressing is during the flowering period, with 60% nitrogen fertilizer and 10% potassium fertilizer, to facilitate the reproductive growth of Salvia miltiorrhiza. The second topdressing is in the middle and late growth period of Salvia miltiorrhiza (mid-August to early September), with the remaining potassium fertilizer applied to promote root growth and development.

In order to meet the trace element needs of Salvia miltiorrhiza throughout the growth period, a certain amount of micro-fertilizer can also be applied at the base, including 30 kg/mu of zinc sulfate, 15 kg/mu of ferrous sulfate, 4 kg/mu of manganese sulfate, 1 kg/mu of boric acid, and 2 kg/mu of copper sulfate.
