High-yield intercropping cultivation of Bupleurum

Bupleurum, alias, Bupleurum, Bupleurum, Solanum, etc., are perennial herbs with a height of 80-100 cm, compound inflorescence, yellow flowers, irregular branches of roots, irregular branches, different thickness, main roots often not obvious, black and white skins, early plant growth, mainly aboveground stems and leaves, later growing roots, seeds should not be planted every other year, and rhizomes are used as medicine. It has the effect of soothing the liver and relieving fever and relieving pain. it is mainly used to treat cold, fever, cold and heat, chronic hepatitis, rib pain or intercostal neuralgia, gynecological diseases and so on.

Bupleurum used to be mainly direct seeding in the field and seedling transplanting. In recent years, in the standardized planting and development of Bupleurum GAP in Fang County, Hubei Province, it is found that the technology of interplanting Bupleurum has many advantages over seedling transplanting and field direct seeding, which is worth popularizing. The main results are as follows: (1) saving man-hours and manpower; (2) solving the problem of shading and moisturizing in the period of Bupleurum, which is beneficial to the preservation of seedlings; (3) interplanting Bupleurum does not affect the yield of interplanting crops in the same year, which can ensure the income every year and make rational use of the land.

Land selection, land preparation and fertilization. Select the soil that is deep, fertile and sparse dare to carry sand, saline-alkali and poorly drained clay should not grow, combined with soil preparation, 3000 kg of farm manure and 20-30 kg of calcium superphosphate are used as base fertilizer.

Sow seeds. First of all, it is necessary to select improved varieties; grow separately, and the disease-free and harmless 2-3-year-old Bupleurum is used as the mother plant from September to November when the fruit changes slightly from cyan to brown, cut back the whole plant, put it in a ventilated and dry place and dry for several days. Then dry, thresh, clean, store and set aside. The seeds should not be left in the next year. Keep stirring the seeds in 55 ℃ water to room temperature, remove the blighted seeds, then wash the sunken full seeds for seed, or soak the seeds for 25 minutes with carbendazim, wash the seeds with clean water to eliminate the surface germs.

The sowing method is divided into sowing and sowing. During strip sowing, open a ditch 2-3 cm deep between the rows of the crop, spread the seeds evenly into the ditch, cover the soil 1-1.50 cm and suppress them slightly; do not rake the seeds temporarily during sowing, spread the seeds evenly to the field, and then rake the seeds 3-4 times to achieve the upper and lower fruit, so as to facilitate germination and emergence, using 2-3 kg of seeds per mu.

When the irrigation condition is convenient, you can wait for the crop to emerge, spread the seeds evenly into the seedling field when releasing the seedling water, and immediately release the water without covering the soil. Bupleurum seeds can only be shallow, not deep, cover the soil not more than 1.50 cm, otherwise it is not easy to emerge.
