Abstract

The invention belongs to the field of plant cultivation and discloses an artificial cultivation method of dioscorea zingiberensis. The artificial cultivation method of the dioscorea zingiberensis comprises steps of seed selection, soil preparation, seed sowing, frame erecting, weeding, fertilizer applying, water drainage, pest control, ridging and harvest. Seed stem preprocessing is performed before seed sowing, and a seed stem preprocessing method is that 50% of carbendazol wettable powder is diluted into 1000 times to soak seed stems for 30 minutes or water is utilized to soak the seed stems for 30 minutes. The fertilizer applying comprises base fertilizer applying and additional fertilizer applying, wherein base fertilizers are compound fertilizers of potassium sulfate, and additional fertilizers are leaf fertilizers. The artificial cultivation method of the dioscorea zingiberensis overcomes the shortcoming that the existing artificial cultivation method of the dioscorea zingiberensis is non-standard in cultivation technology and low in harvest yield and saponin content and results in tuber rot due to blind fertilization, and is standard in cultivation technology, capable of avoiding tuber rot and high in harvest yield and saponin content.

Description

technical field

[0001] The invention belongs to the field of plant planting methods, and in particular relates to an artificial planting method of Dioscorea scutellariae. Background technique

[0002] Dioscorea shield leaf, also known as turmeric and fire head root, is a perennial twining herbaceous vine of the genus Dioscorea in the family Dioscoreaceae. Mainly distributed in the tropics, a few distributed in the subtropical and temperate regions, scattered in the continents of the old and new continents. Dioscorea saponin is contained in the rhizome of yam, and its crude drug can dispel wind and dampness, relax tendons and activate blood circulation, treat arthritis, coronary heart disease and kill snails; the saponin extracted from the rhizome is synthesized and has anti-inflammatory, analgesic and anesthetic properties. It is the main raw material of adrenal cortex hormone, sex hormone and anabolic hormone drugs with the functions of contraception and contraception, and...

Examples

Embodiment 1

[0019] The following table is the planting points of embodiment one, see Table 1:

[0020] Table 1 The amount of base fertilizer per mu

[0021]

[0022] One set of data in the above-mentioned embodiment is selected as an example:

[0023] 1. Soil preparation: Select areas with an altitude of 400-900m that are sunny, warm, relatively high in air humidity, convenient for drainage and irrigation, and free from air, soil, water quality, and industrial pollution. Choose loose, fertile, sandy loam or soil with a pH value of 5-7. For planting in oil sand soil, dig or plow the selected land, level it, remove weeds and stones, and wait for sowing.

[0024] 2. Seed selection: select the rhizomes with strong, uniform, strong vitality, bright and shiny skin color, no pests and diseases, at least two bud eyes at the front end and middle end of the rhizome, about 6cm long, and fresh stems weighing more than 20g. kind. Note: Storing wilted seeds has a certain impact on emergence and...
