Salvia miltiorrhiza cultivation technique four steps

First, the election site preparation

(1) Geological topography: It is better to choose sandy soils with deep soil, loose fertility, high topography and good drainage. Flatland should be used as a drainage ditch; mountains and ridges should be selected for low slopes in Xiangyang, and the slope should not be too large, 10-30 degrees is better. Soil organic matter content should be greater than 8 or more. PH value between 6.5-7.5.

(2) Soil preparation and fertilization: Salvia miltiorrhiza is deeply rooted and is about 33 cm in diameter. Therefore, after the previous harvest, deep-slope the soil more than 35 centimeters, combined with site preparation, per acre applied into the decomposed manure or compost 2500-3000kg, plus superphosphate 50kg, turned into the soil as a base fertilizer. Before planting, plowing once again, the whole leveling is done, a 1.3-meter-wide sorghum is made, and a deep drainage ditch is opened around to facilitate drainage.

Second, the cultivation method

Seedling cultivation: The survival rate of Salvia miltiorrhiza is high, and it is easy to reach seedlings, seedlings, seedlings, and the yield is high and stable. Spring is planted in April-May and autumn is planted in late October. Should not be late as soon as possible, early transplanting, early rooting, early the next year back to green. When planting, dig a hole with a row spacing of 3,223 centimeters on the surface of the plant. The depth of the hole is determined by the length of the root. The appropriate amount of manure is used as the base fertilizer at the bottom of the hole. After mixing with the soil and the hole, 1-2 seedlings planted in the seeds per hole are planted. The planting depth is based on the original natural growth depth of the seedlings, and the buds can be exposed slightly, and the rooting water is poured after planting. Planted on a large area can also be used for half-agricultured operations, where it is used to open trenches, artificial scattered seedlings, landfill and repression.

Third, field management

(1) Loose soil weeding: Salvia miltiorrhiza grows slowly in the early stage, and weeding and weeding are carried out in time. Generally, we apply 1-2 times of topdressing before mulching, and timely weed removal after mulching.

(2) Timely top dressing: 50 kg of ammonium sulfate can be used in the middle of June. Shallow trenches are applied to the sides of the plants, then covered with soil.

(3) Pest control: The main diseases and pests of Salvia miltiorrhiza are root rot and ground tiger. After the onset of root rot, the roots are black and rot and the stems and leaves on the ground are withered. The disease is prone to occur in the hot and humid seasons from June to August. Control can be timely drainage, avoid continuous cropping, can be used 50% carbendazim 1000 times watering. The ground tiger harms the tender seedlings, can use 3% malathion powder 1:10 mixed soil, spread in the row to kill.

Fourth, harvest processing

(1) Harvest time: Spring planted in late autumn to pre-freeze in the same year, autumn planted in the first 10 years after planting in October-November, local stems and leaves withered when digging, harvesting, first dig the roots Surround the mud, then go straight and root the roots. Be careful not to keep the roots intact. Large-scale cultivation can be harvested by machine.

(2) Processing method: After excavating the root strip, do not wash it with water. After removing hairs, repairing Lucy, and trimming the fine tail, spread it in a dry and ventilated place and dry it until it reaches 5-60%. After ~3 days, it can be sold until it is fully dried.
