Embodiment 1

[0053] Stevia Seedlings:

[0054] Mix stevia seeds and soil according to the ratio of 1:5 and sow them in drills, cover the soil with a depth of 1cm, and suppress them immediately after sowing; land preparation and furrow: when preparing the land, apply 2500kg of decomposed manure, manure or compost, 50kg of lime, and ternary compound fertilizer per mu 30kg is used as base fertilizer. After one plow and one rake, a standard furrow with a width of 90cm and a furrow width of 30cm is made. The standard furrow requires that the soil block be fine and the furrow surface level. Mainly, supplemented by phosphorus and potassium fertilizers, followed by spraying, spraying 50% phoxim 1000 times solution on the border surface, covering with black plastic film and spraying pre-emergent herbicides, after preparing the plot, use 96% Jindu per acre Mix 45ml of emulsifiable oil with 45kg of water to spray on the border surface, then cover with black plastic film, and press the film edge with ...

Embodiment 2

[0084] Stevia Seedlings:

[0085] Mix stevia seeds and soil according to the ratio of 1:7 and sow them in drills, cover the soil to a depth of 1.5cm, and suppress them immediately after sowing; land preparation and furrow: when preparing the land, apply 2800kg of decomposed manure, manure or compost, 70kg of lime, and three-component compound per mu. 40kg of fertilizer is used as the base fertilizer. After one plow and one harrow, a standard furrow with a width of 100cm and a furrow width of 40cm is made. The standard furrow requires the soil block to be fine and the furrow surface to be leveled. Special attention should be paid to applying enough base fertilizer when preparing the land. The base fertilizer is organic fertilizer Mainly, supplemented by phosphorus and potassium fertilizers, followed by spraying, using 40ml of 20% quick-killing EC and 50kg of water to spray on the border surface, covering with black plastic film and spraying pre-emergent herbicides, after prepari...

Abstract

The invention relates to a stevia cultivating technology which comprises the following steps: growing stevia seedlings; transplanting; performing complementary planting of seedling; performing cultivation and earthing up; performing cultivation and weeding; performing irrigation; performing top dressing; performing pest control; dealing with disease; harvesting; and storing dry leaves. According to the invention, high-quality stevia can be cultivated, the stevia yield is increased, the phenomenon that the demand for stevia exceeds supply is solved, large-area popularization of stevia cultivating is facilitated, and national income is increased.

Description

technical field [0001] The invention relates to a stevia planting 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, layering,...
