Embodiment 1

[0024] Embodiment 1 Embodiment of the present invention

[0025] Follow the steps below

[0026] 1. Site selection

[0027] In Lijiang City, Yunnan Province, the altitude is 2600m, the frost-free period is 150 days, and the soil is sandy loam;

[0028] 2. Land preparation

[0029] The previous crop of the field was white cloud beans, which were deeply plowed and exposed to the sun in autumn. After two plows and two harrows, fertilization was carried out in February of the following year. The box was 80 cm wide, 20 cm high, and 25 cm wide. The direction of the box was consistent with the slope of the plot. The length of the compartment is determined according to the specific terrain. The base fertilizer is composed of decomposed farmyard manure and N≥15% in mass fraction, P 2 o 5 ≥15% and K 2 O ≥ 15% compound fertilizer composition, base fertilizer applied to decomposed farmyard manure is 30000kg / hm 2 , applied with N≥15% calculated by mass fraction, P 2 o 5 ≥15% and K...

Embodiment 2

[0050] Embodiment 2 and embodiment 3 are also embodiments of the present invention, except that the technical measures listed in table 3 are different, all the other operating methods are the same as embodiment 1, and will not be repeated. See Table 3 for the differences.

[0051] Table 3 embodiment 1, embodiment 2 and embodiment 3 operation difference and its effect

[0052]

[0053] The urea applied in Table 3 is all urea containing N ≥ 45% calculated by mass fraction, and the compound fertilizers applied are all urea containing N ≥ 15% calculated by mass fraction, P 2 o 5 ≥15%, K 2 O≥15% compound fertilizer.

[0054] According to the above examples, after the harvest of the fine varieties of fenugreek, the average harvest seed per mu is 767kg / hm 2 , The average thousand-grain weight of the seeds is 24.9g, the average seed germination rate is 93.9%, and the average seed clarity is 98%.

Embodiment 4

[0055] Embodiment 4: (contrast) traditional way of saving seeds

[0056] Traditional way of saving seeds: Usually only before the seeds mature, select plants that grow vigorously and are free of diseases and insect pests in the field, do not remove flower buds, and reserve them for seed collection, or select robust and tidy plots, and carefully manage them as reserve fields. During the seed maturity period from July to August, I often go to the seed field to observe. When the flower stalks turn yellow, the flower buds turn yellowish brown, and the upper part of the flower buds has not yet spread out, harvest them in time. Remove the sundries, pack the pure seeds into bags, and store them in a ventilated and dry place for later use.

Abstract

The invention discloses a saussurea lappa fine variety breeding method, and belongs to the technical field of medicinal plant breeding. In the method, sand loam with the altitude between 2,600 and 2,900m and the frostless season more than 250 days is selected; 22,500 to 45,000kg/hm<2> of well-rotted farmyard manure and 225 to 450kg/hm<2> of compound fertilizer containing more than or equal to 15 percent of N, more than or equal to 15 percent of P2O5 and more than or equal to 15 percent of K2O are applied as base fertilizers; in the period of the first 1 to 2 years, urea containing more than or equal to 45 percent of N and/or the compound fertilizer are used as the additional fertilizer for three times; and the triangular hole sowing distance is 10-20cm*20-30cm, and the seeding quantity is 12-15kg/hm<2>. The method can make the seed yield reach 742 to 783kg/nm<2>, the thousand seed weight reach 24-25.6g, the seed sprouting percentage reach 93-95 percent, and the seed purity reach 97-99 percent, which are respectively improved by 90 to 100 percent, 19 to 25 percent, 31 to 33 percent and 22 to 24 percent compared with the contrasts.

Description

technical field [0001] The invention belongs to the technical field of medicinal plant breeding, and in particular relates to a method for breeding fine varieties of cedarwood. Background technique [0002] Aucklandia lappa Decne. is a plant of the genus Asteraceae. It has a long history of medicinal use and is one of the main raw materials of many Chinese patent medicine formulas. It has the effects of promoting qi and relieving pain, invigorating the stomach and eliminating food. It is used for distending pain in the chest and abdominal cavity, heavy diarrhea after diarrhea, persistent indigestion, lack of appetite, and abdominal pain due to diarrhea. Yunmuxiang is native to India. It was planted in Lijiang, Yunnan in 1935 and gradually spread to the whole province. It was exported for the first time in 1959 and was known as "Cloud Wood Fragrance". Now my country's Yunnan, Guangxi, Sichuan, Gansu, Shaanxi and other provinces have introduced and cultivated. At present, t...
