Planting method and time of Salvia miltiorrhiza

The root propagation time of Salvia miltiorrhiza is from March to April in spring. The cutting breeding time of Salvia miltiorrhiza is from June to July in the north and from April to May in the south. The seed propagation time of Salvia miltiorrhiza was sown in March. Planting method of Salvia miltiorrhiza: suitable for planting in slightly acidic or slightly alkaline sandy soil, 5000-10000 kg fertilizer per mu, 2-3 Salvia miltiorrhiza seedlings per hole, and soaking the soil thoroughly after planting.

Planting time of Salvia miltiorrhiza

1. Root propagation time of Salvia miltiorrhiza

After harvesting Salvia miltiorrhiza in autumn, Radix Salviae Miltiorrhizae, which is 0.7-1cm in diameter, purplish red in color, free of diseases and insect pests, developed throughout the year, wet sand to spring, and then the cut root was placed vertically in the hole from March to April of the following spring.

2. Cutting breeding time of Salvia miltiorrhiza

The main results are as follows: (1) from June to July in the north and from April to May in the south, the healthy and pest-free Salvia miltiorrhiza was cut into 13-16cm long slices. The lower incision should be close to the stem and have the shape of horseshoe, and cut off the 10cm of the lower leaves of Salvia miltiorrhiza according to the row spacing 20cm.

(2) insert the cuttings obliquely into the nursery bed, go deep into the cuttings of 1-2-2-3, then compact the soil, leaving 1-2 leaves on the ground, insert and cut, which can not be placed for a long time, otherwise it is not conducive to the survival rate of cuttings.

3. Seed propagation time of Salvia miltiorrhiza

Generally, the seeds of Salvia miltiorrhiza are planted in the seedbed in March, which can not only be sowed online, but also sowed when sowing.

2. Planting method of Salvia miltiorrhiza

1. Land selection and land preparation

Planting Salvia miltiorrhiza should choose sandy soil with slightly acidic or slightly alkaline. 5000-10000 kg fertilizer can be applied per mu of soil, and deep ploughing soil to 30-40cm, cut and flatten to 90cm width, flat to 24cm width. If the soil is relatively dry during sowing, the soil can be watered through.

2. Breeding methods

The main results are as follows: (1) Salvia miltiorrhiza generally has several planting methods, such as seed, cuttage, ramet, root segment and so on. at present, the yield of root propagation is relatively high, mainly by seedling transplanting and branching.

(2) for those planted with seeds, the seeds can be harvested in batches after Salvia miltiorrhiza matures from July to August. On the whole raft, according to the row spacing of 12-15cm, dig a shallow trench with 1.5cm depth, and then spread the seeds evenly into the ditch to fill the soil flat. During the period, the soil should be kept moist and germinated 10 to 15 days after sowing.

(3) when Salvia miltiorrhiza seedlings grow to 9-12cm, it will be moved to the field, according to row spacing of 24-30cm, spacing of 9-12cm, hole depth of 9cm, 2-3 Salvia miltiorrhiza seedlings can be planted in each hole. After planting, the soil should be watered thoroughly and gently compacted to improve the survival rate of planting.
