Embodiment 1

[0032] The present embodiment provides a kind of preferred selenium-enriched Sichuan ginseng cultivation method, which specifically includes the following steps:

[0033] (1) Site selection and preparation

[0034] It is advisable to choose a plot with a slope of ≤30°, a soil layer thickness of more than 30cm, rich in organic matter, loose and fertile, and well-drained brown loam or yellow-brown loam. In the winter or early spring of the following year, the land should be prepared and plowed, and the plowing depth should be 25cm to 30cm. Use 200~500kg / 667m 2 Commercial organic fertilizer (N+P 2 o 5 +K 2 O≥4.5%) and 25~50kg / 667m 2 Commodity compound fertilizer (N+P 2 o 5 +K 2 O≥45.0%) as base fertilizer. The method of using fertilizer shall be carried out according to NY / T 496. Rake flat slopes to make furrows. The width of the furrow is 80-120 cm, the width of the ditch is 20-30 cm, and the depth is 10-20 cm, which is convenient for operation and drainage.

Embodiment 2

[0050] 1. Materials and methods

[0051] It is advisable to choose a plot with a slope of ≤30°, a soil layer thickness of more than 30cm, rich in organic matter, loose and fertile, and well-drained brown loam or yellow-brown loam. In winter, the soil should be prepared and plowed to a depth of 25cm to 30cm. Rake the smooth slope to make the furrow, the furrow width is 80cm, the furrow width is 20cm, and the depth is 10cm. Use 500kg / 667m 2 Commercial organic fertilizer (N+P 2 o 5 +K 2 O≥4.5%) and 25kg / 667m 2 Commodity compound fertilizer (N+P 2 o 5 +K 2 O≥45.0%) as base fertilizer. Seedlings are transplanted with fresh roots of 1-year-old healthy seedlings, the row-to-plant spacing is 15cm×10cm, and the cultivation density is 35,000 plants / 667m 2 . After the first weeding (in the middle and late April), topdressing urea 5kg / 667m 2 ;For the second time, 15-20 days after topdressing urea, topdress 40kg / 667m 2 Commodity compound fertilizer; the third time in mid-Novem...

Embodiment 3

[0057] 1. Materials and methods

[0058] Select the plots whose conditions are consistent with those of the experimental field in Example 2. In winter, the soil should be prepared and plowed to a depth of 25cm to 30cm. Rake flat slopes to make furrows with a width of 120 cm, a furrow width of 30 cm, and a depth of 20 cm. Use 350kg / 667m 2 Commercial organic fertilizer (N+P 2 o 5 +K 2 O≥4.5%) and 35kg / 667m 2 Commodity compound fertilizer (N+P 2 o 5 +K 2 O≥45.0%) as base fertilizer. Seedlings are transplanted with fresh roots of 1-year-old healthy seedlings, the row-to-plant spacing is 15cm×7cm, and the cultivation density is 45,000 plants / 667m 2 . After the first weeding (mid to late April), topdressing urea 10kg / 667m 2 ;For the second time, 15-20 days after topdressing urea, topdress 30kg / 667m 2 Commercial compound fertilizer; for the third time in mid-November, 200kg / 667m commercial organic fertilizer was applied 2 . The frame is specifically the second year of ...

Abstract

The invention discloses a cultivation method of selenium-enriched codonopsis tangshen Oliv.. On the basis of a conventional cultivation technique, the step of exogenous selenium fertilizer spraying isintegrated; according to exogenous selenium fertilizer spraying, exogenous selenium fertilizer is sprayed to plants of codonopsis tangshen Oliv., and the application amount of selenium of the exogenous selenium fertilizer is 5-40 mg/m<2>. The step of exogenous selenium fertilizer spraying is usually carried out in the third year of the cultivation of codonopsis tangshen Oliv., the exogenous selenium fertilizer is sprayed 1-3 times in the vigorous growth period and flowering period of the plants of codonopsis tangshen Oliv., and every spraying interval is 20 days or longer. Foliar spraying isadopted, the method is convenient to operate and high in efficiency, the total selenium content of the medicinal material of codonopsis tangshen Oliv. reaches 0.27-1.00 mg/kg, and organic selenium accounts for 79.1-84.0%. The method can guide the production of stable and high-quality selenium-enriched codonopsis tangshen Oliv., solves the problems that current cultivation methods of odonopsis tangshen Oliv. are not standardized or uniform and selenium-enriched cultivation techniques are immature, and has high application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and relates to a method for cultivating medicinal and edible homologous plants, in particular to a method for cultivating selenium-enriched Sichuan Codonopsis pilosula. Background technique [0002] Selenium is one of the essential trace elements for humans and animals, and has many beneficial biological functions (Schwarz and Foltz, 1957). It has been found that more than 40 human diseases are related to selenium deficiency or low selenium, such as Keshan disease, Kaschin-Beck disease and cardiovascular diseases. Broadley et al. (2006) believed that artificial selenium supplementation is one of the main ways to prevent and treat various selenium deficiency diseases. Among them, the development and utilization of selenium-enriched products is an important means of artificial selenium supplementation in selenium-deficient areas in my country and the world (Ramos et al., 2010). A...
