Problems solved by technology

In order to avoid the lower leaves from withering, in actual cultivation and production, it is usually harvested when the height is 1.5 m or even lower. At this time, the yield and the content of active ingredients such as volatile oil have not yet reached the optimal level.

Embodiment 1

[0021] Embodiment 1 Irrigation of seedling-promoting liquid improves the first crop emergence efficiency

[0022] According to the chemical reaction 5NaClO+4HCl=4ClO 2 +5NaCl+2H 2 O, the rapid preparation of chlorine dioxide is realized by the reaction of sodium chlorite and hydrochloric acid. Weigh 0.15 g of sodium chlorite into a brown bottle, add 5 mL of distilled water, and after it is completely dissolved, add 0.5 mL of food-grade hydrochloric acid, react for 10 min, add 495 mL of distilled water, and mix to obtain 100 mg / L Chlorine dioxide aqueous solution. The concentration required before use is sufficient.

[0023] In November of the previous year, dig out the roots of wormwood, pick out the young rhizomes, cut them into 4-5 cm long sections, open a ditch at 40-45 cm, and place the rhizomes in the ditch at a plant spacing of 15 cm. inside, and then cover with soil compaction.

[0024] From March 1 to March 10 of the following year, the rhizomes were fully watered...

Embodiment 2

[0025] Example 2 Irrigation of seedling-promoting liquid improves the re-emergence efficiency of residual stalks after harvesting wormwood

[0026] After the previous crop of wormwood was harvested, the residual stalks were fully watered once again with a 40 μg / L chlorine dioxide aqueous solution, and the same amount of water was sprayed as a control. After 7 days of watering, if image 3 As shown, the number of new rhizomes (indicated by arrows) in the treatment group was significantly higher than that in the control group. After 14 days of watering, if Figure 4 As shown in the figure, the number of new seedlings (indicated by arrows) in the treatment group was significantly higher than that in the control group.

Embodiment 3

[0027] Embodiment 3 Spray growth-promoting liquid to regulate the growth of wormwood seedlings

[0028] Two weeks after the emergence of wormwood, an aqueous solution containing 25 μg / L chlorine dioxide and 0.3‰ sodium alkylbenzene sulfonate was sprayed, and the same amount of water was sprayed as a control. It is advisable to spray until the surface of all leaves is wet, and spray continuously for 2 days. 7 days after spraying, such as Figure 5 As shown, it can be observed that the treatment group grows rapidly, and the plant height is significantly higher than that of the control group.

Abstract

The invention discloses a regulation and control method for improving the yield of multiple crops of wormwood in one year, which comprises the following steps: by taking rhizomes as a starting material, irrigating the rhizomes before seedling emergence of the first crop in spring or residual stalks after subsequent harvesting of wormwood once with a seedling promoting solution, respectively spraying a growth promoting solution on leaves in 2 weeks and 6 weeks of seedling emergence, and continuously spraying for 2 days respectively. According to the method, through simple agronomic measures, the chlorine dioxide solution with the specific concentration is used for irrigation to promote seedling emergence of the wormwood rhizomes, growth and elongation of the rhizomes are promoted, the seedling emergence time is shortened, and the seedling emergence quality is improved; a mixed solution of chlorine dioxide and sodium alkyl benzene sulfonate is sprayed in the seedling stage and the adult plant stage to regulate and control plant growth, plant growth is promoted, the leaf area is increased, the chlorophyll content is increased, the biomass is increased, the lower leaf litter condition is remarkably reduced, and the leaf harvesting yield is increased.

Description

technical field [0001] The invention relates to the field of plant production, more specifically to a method for regulating the yield of wormwood for more than one year. Background technique [0002] Wormwood ( Artemisia argyi Levl. et Van) is a perennial herb or sub-shrub of Asteraceae, rich in active substances such as volatile oils and flavonoids. and other effects. In addition to medicinal uses, recent studies have found that Artemisia argyi leaves and stems also have important application value in the fields of food, health care, cosmetics and animal husbandry. Such a wide range of uses has made the domestic demand for mugwort to reach 45,000 to 50,000 tons in 2017, and the demand in 2021 will exceed 80,000 tons. Although the wormwood industry has developed rapidly in the past 10 years, the current scattered farmers account for a large proportion. The standardized planting procedures for wormwood are not yet perfect, and farmers' enthusiasm for production is also se...
