Embodiment 1

[0023] Selected Seeds:

[0024] In August, select plants that are robust and free from diseases and insect pests as seeds. During the blooming period of stevia in September, use long bamboo branches (strips) to shake the plants for artificial pollination. Harvest the seeds on the second day, put them in clean woven bags, and store the harvested stevia seeds in a plastic film bag after drying and removing impurities. The seeds must be selected from the same year;

[0025] Seedbed selection:

[0026] Choose sandy loam or loamy soil that is leeward and sunny, convenient for drainage and irrigation, loose and fertile, good in structure, strong in water and fertilizer retention, and used as rice seedbed before;

[0027] To make a furrow:

[0028] The area of ​​the seedbed is determined according to the ratio of 25:1 between the field and the seedbed. After harvesting in the second night, plow and blanching in time. Before preparing the field for furrows, spread 48% Lesiben granul...

Abstract

The invention relates to the planting technology of stevia rebaudiana, which comprises the following steps of: selecting and retaining seeds, selecting a seedbed, preparing soil and furrowing, processing the seeds, sowing and managing in a seedling stage. By the technology, high-quality stevia rebaudiana seedlings can be cultivated, the yield of the stevia rebaudiana can be improved, and the problem of short supply of the stevia rebaudiana on the market can be solved, so the technology is favorable for popularizing the planting of the stevia rebaudiana in large area, and increasing national revenue.

Description

technical field [0001] The invention relates to a stevia seedling raising technology. Background technique [0002] Stevia is also known as stevia. The whole plant contains glycosides, and the leaves have the highest sweetness and can be used as sweeteners. Native to Paraguay, South America. China successfully introduced and cultivated it in the south of the Yangtze River in the 1970s, with a plant height of 90-100 cm. The stem is about 1 cm thick, strongly branched, and the old stem is semi-lignified. Leaves obovate or broadly lanceolate. The middle and upper leaves have coarse teeth, bright green and rough surface. There are short hairs. The flower heads are arranged in corymbs. Seeds fusiform. Stevia is a short-day crop that requires an average annual temperature of 21-22°C and is suitable for planting in fertile soil with good water retention. Seeds need light to germinate, so it is not advisable to sow deeply when propagating with seeds. Generally, cuttings, l...
