Abstract

The invention provides a lithospermum erythrorhizon planting method. The lithospermum erythrorhizon planting method comprises the steps that loose fertile sandy soil with high terrain and excellent drainage is selected as cultivated land for cultivating; before farming, 75,000 kg of farmyard manure is applied per hectare planting land, deep ploughing for more than 30 cm is carried out, the soil is finely prepared and flattened by raking, and beds with the width of 100 cm is prepared to be ready for cultivating; seed treatment comprises the steps that seeds are evenly mixed with fine sand in the ratio of 1 to 3 in the late October to the early November, the seeds are stored in pits, the soil pits with the depth of 45 cm and the length and width both of 30 cm are digged at a sunny slope, asmall amount of branches are placed at the pit bottoms, a layer of leaves is paved on the branches, and the seeds are placed in the pits, and covered with soil for 10 cm; after before and after the tomb-sweeping day of the next year, cultivation is not carried out until the seeds are germinated; field management comprises the steps that during the period of seedlings, the wall surface is high in temperature and directly shot by sunlight, and watering, weeding and soil loosening are carried out; timely draining is carried out in the dry season; and when the seedling height is 20-25 cm, 20-25 catties of calcium superphosphate is applied per mu, and soil covering and watering are carried out after fertilizer is applied. According to the lithospermum erythrorhizon planting method, soil preparation and fertilizer feeding, seed treatment, field management and the other measures in the early stage of sowing are used, the yield of lithospermum erythrorhizon is improved, a finished product is white in color and fragrant in smell, and the requirements of the market are met.
