1. Land selection and preparation

Radix Salviae Miltiorrhizae prefers warm and humid environment with sufficient light and is not tolerant to low temperature. at a low temperature of minus 5 degrees, the stems and leaves will suffer frost damage, but the roots can survive the winter and can not bear high temperature, and the seedlings will stop growing and die and avoid waterlogging at the seedling stage. When planting, it is necessary to select plots with high terrain, deep soil layer, loose and fertile land and good drainage, apply rotten farm manure as base fertilizer, shape and rake flat to make beds, waiting for sowing.

2. Seedling raising and transplanting

Ditch on the border surface according to the row spacing of 30 cm, the ditch depth is about 1 cm, stir the seeds and fine sand evenly and sprinkle them into the ditch, do not see the seeds in the soil, cover the ground after sowing, keep warm and moisturize, in order to facilitate seedling emergence. After emergence, it is necessary to punch the plastic film and release the seedlings. When the seedlings grow in 5-6 cm time, they can be transplanted in late May. Transplanting can be spring or autumn, spring planting in May, autumn planting in October, early transplanting and early rooting. When transplanting, dig holes according to the row spacing of 23 × 33 cm, apply base fertilizer at the bottom of the hole, and put 1-2 strong seedlings in each hole.

3. Field management

It is necessary to do a good job of weeding, watering and fertilization after transplanting, generally three times a year to promote its growth, pay attention to the depth when ploughing, so as not to damage the root system, pay attention to the concentration and amount of fertilizer when fertilizing, and pay attention to drainage measures in the rainy season to avoid stagnant water and rotten roots, and timely watering in times of drought. When Radix Salviae Miltiorrhizae shows buds, except for seeds, the rest should be cut off, concentrate nutrients and roots, and improve yield and quality.

4. Pest control

The main diseases of Radix Salviae Miltiorrhizae are leaf spot disease, root rot disease and root nematode disease. Leaf spot disease can be controlled by spraying 0.3% potassium dihydrogen phosphate or carbendazim and topiramine; root rot disease can be controlled by spraying carbendazim and methyl topiramine; root nematode disease can be rotated reasonably and treated with methyl isophos. The main pest is Spodoptera litura, which is harmed by larvae, and when it is serious, it will gnaw the leaves clean. after harvest, it is necessary to clean up the residual branches and diseased leaves, and spray fenvalerate, omethoate, trichlorfon and other insecticides.
