seed treatment
If Bupleurum seeds are not treated before sowing, the germination time will be longer and the emergence rate will be poor. Therefore, it needs to be treated before sowing. There are three main processing steps: first, scouring the seeds, soaking the Bupleurum seeds with water, and skimming off the mildew seeds and husks floating on the water surface; The potassium permanganate solution should not be too much. It is better to flood the seeds with the liquid surface to avoid waste and environmental pollution; then filter the potassium permanganate solution and mix it with plant ash and soil. The mixing ratio is 1 part of seeds: 1 Parts Plant Ash: 1 part Fine Soil. Germination treatment is generally not carried out in areas with poor irrigation conditions. In order to avoid water shortage after germination and death.
Thinning, replenishing seedlings
Seedlings usually emerge about 20 days after sowing. Before emergence, keep the soil moist, and cover with wheat straw, straw and other mulch 2cm thick. When the seedlings are basically all out, the cover is removed, and the seedlings are fully exposed to sunlight, and the seedlings are thinned and replenished when the seedlings are 15 cm high. The plant spacing is 5cm, and it should not be too densely planted, otherwise it will affect the yield of the product.
