Problems solved by technology

As a new variety of purple yam, Xunong purple yam cannot be propagated and cultivated in the same way as ordinary white yam. It can be purified and rejuvenated by its own yam beans.
At present, purple yam is planted and propagated by cutting tubers, and its reproduction coefficient is only 10-15 times, which greatly limits the propagation and promotion of purple yam, and the survival rate and survival quality of purple yam seedlings after cultivation are poor

Embodiment 1

[0014] A purple yam seedling raising and cultivation method, comprising the following steps,

[0015] (a) Purple yam tuber planting: From April 6th to 10th, select the Xunong purple yam tuber with a weight of 60g / piece, soak it with root powder No. 5 medicinal solution with a concentration of 600ppm for 80s, and completely immerse the tuber 3cm below the liquid surface , take it out, dry the surface, and plant the purple yam tubers on the seedbed. The seedbed is composed of fine soil or nutrient soil added with farmyard manure. The overall humidity of the soil is suitable. The space is 20×20cm 2 After planting, the thickness of the covering soil is 3-5cm. When planting, evenly spray 200-300ml of water, and then spray 150-200ml of water on the seedbed every 7 days until the end of April;

[0016] (b) Preparation of purple yam seedlings: on May 10-25, spray paclobutrazol powder 6g / mu on the seedbed after planting, spray once every 5 days, and spray 3 times continuously, until t...

Abstract

The invention discloses a purple yam seedling raising and cultivating method and belongs to the technical field of Chinese yam cultivation. The method comprises the following steps: (a) purple yam stem tuber planting; (b) purple yam seedling preparation; (c) purple yam seedling cuttage; (d) purple yam seedling growth; (e) purple yam harvesting. During purple yam planting, seedling cuttage, thermal insulation, moisture preservation and pesticide spraying are adopted to promote rooting and germinating of seedlings, so that the seedling yield and seedling raising and cultivating quality of purple yams are effectively ensured; the cut purple yam seedlings are subjected to a sieving test, so that the later-stage growth quality of purple yam is ensured; By virtue of adjusting the temperature and humidity of soil in a cuttage shed, rapid germination and seedling raising for stem tuber are ensured; during the seedling growth stage, fertilizers are reasonably applied, so that the purple yam propagation coefficient is effectively improved; during yam seedling growth process, a proper amount of fertilizer is applied for multiple times, so that continuous and applicable fertilizer support is provided for seedling growth, the survival rate and survival quality of purple yam seedlings are ensured, and propagation and popularization of purple yam are really promoted.

Description

technical field [0001] The invention relates to a purple yam seedling raising and cultivation method, belonging to the technical field of yam cultivation. Background technique [0002] Purple yam, also known as "purple ginseng", is eaten with its plump tuberous root or cylindrical root. Purple yam is rich in anthocyanins and has a wide range of uses. , can lower blood pressure, blood sugar, anti-aging and prolong life, strengthen brain and invigorate intelligence, and enhance human immunity. As a new variety of purple yam, Xunong purple yam cannot be propagated and cultivated in the same way as ordinary white yam, which can purify and rejuvenate its excellent properties by forming yam beans itself. At present, purple yam is planted and propagated by cutting tubers, and its reproduction coefficient is only 10-15 times, which greatly limits the propagation and promotion of purple yam, and the survival rate and survival quality of purple yam seedlings after cultivation are rel...
