A technology of direct seeding planting of Erigeron breviscapus in a small shed

Abstract

The invention relates to plastic-tunnel erigeron breviscapus (vant.) low-tunnel direct seeding planting technology. The technology is characterized by changing transplanting to direct seeding and adopting such technical measures as arching, film mulching and the like. The technology has the following advantages: the moisture is controlled in rainy seasons and the temperature is raised in winter, thus providing better growth environment for erigeron breviscapus (vant.) low-tunnel; the yield and quality are improved; more than 340-360kg of dry products of erigeron breviscapus (vant.) low-tunnelcrude drugs are obtained per mu; the average scutellarin is 2.8%; the content of the impurities is below 2%; the pesticide residual quantity is low; various diseases caused by pathogen infection of roots are effectively controlled; and meanwhile, the cost input in the transplanting process can be saved by direct seeding, thus lowering the planting cost.

Description

technical field

[0001] The invention relates to a live planting technology of scutellaria breviscapus in a small arch shed. It belongs to the field of planting technology. Background technique

[0002] Erigeron breviscapus (Vant.) Hand-Mazz is a perennial herb of the genus Asteraceae. Erigeron breviscapus medicines are currently the best natural medicines for treating obliterative cerebrovascular diseases and sequelae of cerebral hemorrhage, with an effective rate of over 95% and few side effects, so they are very popular among patients. In 1995, the State Administration of Traditional Chinese Medicine designated it as an essential Chinese patent medicine in emergency departments (rooms) of Chinese hospitals across the country.

[0003] There are few related studies on the artificial planting of breviscapus. Known methods such as application tissue culture, hydroponics, branching, propagation and seed propagation propagate seedlings, wherein the harvesting and storage met...
