New planting method of salvia miltiorrhiza

Salvia miltiorrhiza is planted with seeds, and it is generally necessary to raise seedlings first to ensure the effect. Seedling raising is carried out at the end of June or the beginning of July after harvesting Salvia miltiorrhiza seeds. Apply 1 0,00000kg of fully decomposed manure or green manure and 10kg of diammonium phosphate every 667m, plough over 20cm, and level the border with a width of 1.2m and a width of 30. 2.5 ~ 3.5 kilograms of seeds for seedling cultivation every 667 meters. Mix the seeds with 2 ~ 3 times of fine soil evenly, spread them on the seedbed evenly, pat them gently with a broom or shovel to make them fully contact with the soil, cover them with wheat straw or wheat bran until the soil is not exposed, and then pour them thoroughly. Check the seedbed every day to observe the water content and germination of the seedbed. In case of drought, spray clear water on the mulch to keep the seedbed moist. Weeds should be pulled out by hand in time after emergence. If the seedlings are too dense, the spacing between seedlings should be about 5 cm. When transplanting and planting, apply1300 ~ 2,000 kg of fully decomposed manure or green manure and10 ~/7 kg of diammonium phosphate as base fertilizer every 667 meters, turn over the depth by 30 ~ 35 cm, trim and rake, and make ridges with a width of 80 cm and a height of 20 cm, leaving 25 cm between the ridges. From late October of 65438+1to early October of165438+1,plant at the row spacing of 20 ~ 25 cm× 20 ~ 25 cm, and make holes on the ridge surface, and the depth of holes shall be subject to the straightness of seedling roots. Stand the seedlings vertically in the hole, soil them and compact them until the buds are slightly exposed. After planting, irrigate the roots according to soil moisture to avoid flooding.

Besides seeds, Salvia miltiorrhiza can also plant reed heads and seed roots. Reed head planting: when digging Salvia miltiorrhiza, select plants with strong growth and no plant diseases and insect pests, cut off the main roots for medicine, plant fine roots with diameter less than 0.6 cm on the rhizome together with reed head, and dig pits or furrows at the row spacing of 25 cm× 20 cm from the end of 10 to110. Seed root planting: when harvesting Salvia miltiorrhiza in autumn, select red, non-decaying, well-developed root strips with a diameter of 0.7-65438±0.0cm cm as seed roots, store them in wet sand until the next spring, dig pits or furrows with a row spacing of 20cm× 25cm, and the pit or furrow depth is 7-9cm, and apply 0.25kg of manure or soil miscellaneous fertilizer to each pit.
