example 1

[0018] Example 1: In June 2010, 5.2 mu of well-drained red loam soil was planted in the experimental base of Qianshan Company, Jinma Town, Luxi County, and the base fertilizer was 2900kg / mu of decomposed farmyard manure + 40kg / mu of superphosphate, with 0.8g Seed per square meter, cover with straw after sowing, build a small shed after sowing, insert bamboo slices into the soil at the edge of the moisture surface at a distance of 60cm, form an arch with a height of 40cm, and then use 0.02cm thick agricultural The film is covered on the small arch, and after the seedlings are fully emerged, one-third of the straw is peeled off. When the seedlings grow to 2-3cm, one-third of the straw is peeled off. When the seedlings grow to 4cm, they are all uncovered. At the 6-leaf stage, the first topdressing, the topdressing amount is 2kg urea + 5kg superphosphate + 2kg calcium potassium sulfate per mu. After the second topdressing, after an interval of 10 days, use 3kg+superphosphate 8kg+p...

example 2

[0019] Example 2: Example 1: In November 2010, 5 mu of well-drained yellow loam soil was planted in the Qianshan company's breviscapine planting experimental base in Zhongshu Town, Luxi County, and the base fertilizer was 1500kg / mu of decomposed farmyard manure+40kg / mu of superphosphate. Sow at a seeding rate of 1.0 grams per square meter, cover with pine hair after sowing, and then cover it with agricultural film until mid-December, build a small arch shed, and insert bamboo slices into the soil at the edge of the moisture surface at a distance of 80 cm to form an arch Build an arch with a height of 30 cm, and cover the original plastic film on the arch. After the seedlings emerge, remove one-third of the loose hairs. When the seedlings grow to 2-3 cm, remove one-third of the loose hairs. When the seedlings grow to 4cm, they are all uncovered. At the 5-6 leaf stage of the seedlings, 2kg of urea + 5kg of superphosphate + 2kg of potassium sulfate are used for the first time and ...

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...
