example 1

[0021] Example 1: From June 2010 to March 2011, 2.6 mu of breviscapine planting experiment base was planted in the small village of Qianshan Company, Zhongshu Town, Luxi. The base fertilizer is 2500kg / mu of decomposed farmyard manure + 40kg / mu of superphosphate; sowing management is carried out according to the planting technology of Erigeron breviscapi. 2kg urea + 5kg superphosphate + 2kg calcium potassium sulfate; the second topdressing was carried out 12 days after the first topdressing, and the amount of topdressing was 3kg urea + 8kg superphosphate + 3kg potassium sulfate; the second topdressing was carried out 15 days after the second topdressing Three times of topdressing, the amount of topdressing is 3kg urea + 8kg superphosphate + 3kg potassium sulfate per mu; the fourth topdressing is carried out 23 days after the first cutting of Erigeron breviscapus, and the amount of topdressing per mu is 3kg of urea + 8kg of superphosphate + 3kg of potassium sulfate 25 days after...

example 2

[0022] Example 2: From November 2009 to December 2010, 8 mu were sown in the Jishuang Dengzhan planting experimental base of Qianshan Company, Zhongshu Town, Luxi County, and the base fertilizer was 3000kg / mu of decomposed farmyard manure + 40kg / mu superphosphate; The planting technology of Erigeron breviscapus is sowing management. When Erigeron breviscapus grows to 4-6 leaves, the first topdressing is carried out. The amount of topdressing is 2kg urea + 5kg superphosphoric acid + 2kg calcium potassium sulfate per mu; 12 days after the first topdressing Carry out the second topdressing, the amount of topdressing is 3kg urea + 8kg superphosphate + 3kg potassium sulfate; carry out the third topdressing 15 days after the second topdressing, the amount of topdressing is 3kg urea + 8kg superphosphate + 3kg potassium sulfate per mu ; 24 days after the first cut of Erigeron breviscapus, the fourth topdressing was carried out, and the dosage per mu was 3kg of urea + 8kg of superphosph...

Abstract

The invention relates to a fertilizing technique for improving yield of erigeron breviscapus and provides a fertilizing technique for artificially planting the erigeron breviscapus aiming at the defects that the existing artificial planting yield of the erigeron breviscapus is lower and planting cost is high. The fertilizing technique comprises the following steps: based on 1500-3000kg of cured farmyard manure and 40kg of superphosphate as base fertilizers per Mu, carrying out top application five times in different growth periods of erigeron breviscapus seedlings, with reasonable field management. By using the fertilizing technique in the invention, the farmyard manure for the planted erigeron breviscapus product can be saved by 1500kg per Mu, top application is carried out five times, 7kg of urea per Mu can be saved, 3kg of calcium superphosphate per Mu can be saved, and the use cost of the fertilizer is reduced, yield per Mu is increased by 50kg, the content of breviscapine is improved by 0.2%, and the content of impurities is reduced by 1%.

Description

1. Technical field [0001] The invention relates to a fertilization technology for artificial planting of scutellaria breviscapus. It belongs to the field of planting technology. 2. Background technology [0002] Erigeron breviscapus (Vant.) Hand-Mazz is a perennial herb of the genus Asteraceae and is the best natural medicine for treating cardiovascular and cerebrovascular diseases and sequelae of cerebral hemorrhage. Due to disorderly and excessive excavation, wild scutellaria resources have declined sharply. After 2000, wild scutellaria has been difficult to collect on a large scale. There are few studies on large-scale planting of scutellaria breviscapus. In 2004, the patent No. 200410040722.6 was invented by our company. For the first time, the fertilization technology in the technology of artificially planting scutellaria breviscapus is disclosed, and this fertilization technology can only be used in the transplanting and planting of scutellaria breviscapus. The amou...
