Embodiment 1

[0027] (1) planting:

[0028] Seed collection: Collect mature seeds in early September, and the mature seeds are dark red; after collecting the seeds, soak them in water for 6 days, crush the arils, wash and dry them, and store them in a cool and dry place indoors;

[0029] Select a nursery site: choose a light-transmitting broad-leaved forest or vegetation area, and choose a soil with a deep soil layer, loose structure, rich humus, and good drainage;

[0030] Planting: plant yew seeds that have undergone germination treatment in the selected seedlings, and sow in December 2007, planting 10,300 southern yew seeds per mu of land; when sowing, the wound surface needs to be leveled, and the bed water should be irrigated; the seeds need to be suppressed, Contact with the soil, and then cover with river sand, the thickness of which is 3 times that of the seed grains; after sowing, weeds in the woodland should be completely cut off, litter and leaves should be cleaned, and the clean...

Embodiment 2

[0037] The southern yew planting and harvesting method and the 10-DABIII measuring method are the same as in Example 1.

[0038] Planting in November 2007, 9,800 saplings of southern yew were planted per mu of land. On February 18, 2010, 10 acres of 3-year-old southern yew were topped off for the first time, and on September 19, 2011, the top was cut for the second time. The top was harvested on March 21, 2011, and the harvested amount was 2.58 tons of branches and leaves, and the 10-DAB content in the branches and leaves was 1.08g / kg.

Embodiment 3

[0040] The southern yew planting and harvesting method and the 10-DABIII measuring method are the same as in Example 1.

[0041] Sowing in December 2007, 8,900 yew saplings were planted per mu of land. On September 15, 2010, 10 mu of 3-year-old southern yew land was topped off for the first time, and on March 16, 2011, for the second time. In 2011 On September 16, 2009, the top was harvested, and the harvested amount was 2.50 tons of branches and leaves, and the 10-DAB content in the branches and leaves was 1.05g / kg.

Abstract

The invention provides a planting and harvesting method for improving the 10-DABIII content of artificially planted laxus malrel, relates to a method of obtaining the artificially planted laxus malrels through planting, top cutting and harvesting on laxus malrel and extracting 10-DABIII in the artificially planted laxus malrel, and belongs to the technical field of laxus malrel culture. According to the method, the seeding is carried out in February to June or September to December in the first year, 5000 to 10000 laxus malrel is planted in each acre of land, twice top cutting is respectively carried out in February to June or September to December in the third year and September to December in the third year or February to June in the fourth year when the tree age is 3 or 4 and the tree height is 50 to 70cm, and the top cutting and harvesting are carried out on new branches grown after the twice top cutting. The method provided by the invention has the advantages that the problem of 10-DABIII medicine source lack is effectively solved, in addition, the efficiency of industrially extracting the 10-DABIII can also be improved, the production cost of medicines such as paclitaxel and the like is reduced, the medicine cost load of patients is reduced, and huge economic benefits and social benefits are generated.

Description

technical field [0001] The invention relates to a planting and harvesting method for increasing the 10-DABIII content of artificially planted southern yew, and relates to a method for obtaining artificially cultivated yew through planting, truncating and harvesting and extracting 10-DABIII from the southern yew The invention belongs to the technical field of yew cultivation. Background technique [0002] Southern yew (scientific name Taxus chinensis var.mairei Cheng et L.K), also known as beautiful yew, is a national Class I protected plant. It is mainly produced in the south of the Yangtze River Basin in my country. It often grows in mountain forests below an altitude of 1000-1200m and is scattered. Guiyang City is mainly distributed in Huaxi, Wudang, Kaiyang and Xifeng. Anhui Province is mainly distributed in Shimen Township, Shexian County, Huangshan City and Huangshan District. It is also widely distributed in Baishanzu National Reserve in Zhejiang Province, among which...
