Embodiment 1

[0044] Experimental location: Shuitian Township, Mengzi City, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province.

[0045] (1) Site selection and preparation

[0046] In April 2017, in Shuitian Township, Mengzi City, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, the altitude ranges from 600 to 800 meters, the annual average temperature is 20°C to 28°C, the slope is 15° to 30°, and the soil organic matter content is greater than 15% / kg soil , The previous crop is corn, and the clay loam soil is convenient for drainage and irrigation. Clean up the weeds, dead branches and residual roots on the soil surface, plow the topsoil 20cm-30cm deep, and let it dry for 15 days. Then rake 3 to 5 times until the largest soil mass particle size is ≤ 2cm, sort out a tile-shaped seedbed with a width of 110 to 130cm and a height of 15 to 25cm, and the width of furrows between adjacent seedbeds is 27 to 33cm.

Abstract

The invention discloses a marsdenia tenacissima direct-seeding breeding method. According to requirements of the method, land selection, land preparation and seedbed construction are performed in a time period of March to April every year. By measures of pre-seeding seedbed treatment, direct-seeding medium preparation, pre-seeding seed treatment, after-emergence seedling maintenance, field topdressing and the like, harms caused by pest and disease damages of nematode, root rot, aphids and the like to seedlings can be effectively prevented and controlled, seedling breeding time is short, the seed emergence rate reaches 85% or above, the seedling survival rate reaches 78% or above, and sufficient seedlings can be provided for large-area planting of marsdenia tenacissima.

Description

technical field [0001] The invention relates to a direct-seeding breeding method of vine vine seeds, which belongs to the technical field of medicinal plant cultivation and seed seedling cultivation. Background technique [0002] Tongguan vine (Marsdenia tenocissima (Roxb) Wight et Arm) is a perennial deciduous climbing vine belonging to the family Ascariaceae. The Tongguan vine referred to in the Pharmacopoeia is the dry cane of the plant, which has the effects of relieving cough and relieving asthma, eliminating phlegm, clearing milk, clearing away heat and detoxification. For dyspnea and cough with excessive phlegm, postpartum milk barrier, rheumatic swelling and pain, sore and carbuncle. In recent years, studies have shown that the chemical components such as C21 steroids contained in Tongguanteng have anti-tumor pharmacological activities. [0003] Based on the in-depth research on the pharmacological active ingredients of Tengguan vine, the demand for the supply of m...
