Problems solved by technology

However, due to the drought in the northern Bupleurum chinensis production area, especially in spring and summer, the emergence rate is often too low, or even no seedlings, resulting in serious waste of seeds

Embodiment Construction

[0009] The method for sowing Bupleurum seedlings of the present invention will be described in detail through specific examples below.

[0010] In March 2010, a comparison test of Bupleurum seedlings was carried out in Xibaozi Village, Gongchang Town, Longxi County. The soil of the test site is irrigated soil, the previous stubble is potato, and the altitude is 1786m. The field test is divided into two comparative treatment schemes A and B, and the area of ​​the plot is 15m 2 . A: Straw mulching, B: Direct sowing without mulching, which is the control treatment. Both are planted in small areas in local areas by traditional methods.

[0011] A treatment operation method: On April 28, 2010, Bupleurum seeds were soaked in 1.0% potassium permanganate aqueous solution for 6 minutes, the seeds were removed and drained, and covered with gauze to accelerate germination for 20 hours. Then use 70% thiophanate-methyl wettable powder mixed with moist fine sand to dress the seeds, the ...

Abstract

The invention discloses a method for seedling protection and sowing of radix bupleuri in a dry farming area. The method comprises that radix bupleuri seeds are immersed in a potassium permanganate aqueous solution, fished out to be drained and covered by gauze for germination accelerating, and then seeds are dressed with thiophanate methyl wettable powder and wet fine sandy soil; seeds are sowed when soil is wet in spring; crop straw is used for covering immediately after sowing; thinning and final singling of seedlings are conducted when radix bupleuri seedlings grow to 4-6cm; and crop straw covering layers are covered by fine soil of 1-2cm in mid November, so that radix bupleuri seedlings can live through the winter in fields. According to the method, the measure of covering with the crop straw is adopted, so that the soil surface moisture content is kept stable effectively, the soil surface moisture condition is improved, the radix bupleuri emergence rate and the seed survival rate are greatly improved, the yield of the radix bupleuri is improved, and the supply of radix bupleuri medicinal herb resources is guaranteed; and simultaneously, seed resources are saved, and production costs are reduced. Tests prove that by the aid of the method for seedling protection and sowing, the average emergence rate of the radix bupleuri is improved by 18.0%, and the average yield of the radix bupleuri is improved by 20.8%.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese herbal medicines, and relates to a method for sowing Bupleurum bupleuri, in particular to a method for sowing Bupleurum bupleurum seedlings in dry farming areas. Background technique [0002] Bupleurum is the dried root or whole plant of Bupleurum or Bupleurum angustifolia. According to different characters, the former is commonly called "Northern Bupleurum", and the latter is called "South Bupleurum". Bupleurum bupleurum is a traditional Chinese medicinal material commonly used in my country. It has been used for more than 2,000 years.
