Embodiment 1

[0032] Choose 1 mu of sandy loam on the newly opened up wasteland in the east-west direction, turn the ground, prepare the ground, and rake the ground in the first winter, build a 2m high greenhouse, open the compartment at 1.5m, and apply 50kg of compound fertilizer as the base fertilizer when the compartment surface is flat, and the compartment surface is fine, 2 Planted on the 25th. Wash the seeds with newly drawn well water to remove the deflated seeds. Before sowing, the seeds of Araceae were soaked in 100ppm gibberellin + 500 times carbendazim + 1000 times thiophanate-methyl solution at constant temperature for 1 night (12h). The temperature of the solution was kept at 28°C. Double the amount of river sand for seeds, mix the river sand and seeds evenly, and then put them into the mixer for grinding for 50 minutes.

[0033] Spread 5cm thick new mix soil on the surface of the box (the mixing ratio of newly opened wasteland soil and sieved river sand is 1:1), level it, sow...

Wash the seeds with newly drawn well water to remove the deflated seeds. Before planting, soak Aracea seeds in 100ppm gibberellin + 500 times carbendazim + 1000 times thiophanate-methyl solution at constant temperature for 1 night, keep the temperature of the solution at 25°C, remove the next day, drain the water, and mix in 10 times the amount of seeds The plant ash, river sand and seeds are mixed evenly and then put into the mixer to grind for 45min.

[0037] Spread 5cm thick river sand with a thickness of 10-20 mesh on the car surface, level it, sow 3kg evenly, cover the river sand with 2cm,...

Abstract

The invention provides a large-scale seedling cultivation method using Arisaema heterophyllum seeds. The technical scheme includes: determining a nursery garden land selection demand for direct seeding of the Arisaema heterophyllum seeds; determining the sowing time; processing the seeds; establishing a shed and beds; sowing the seeds; performing management before seedling emergence; performing early stage management after seedling emergence; performing middle-later stage management after seedling emergence; and performing transplanting. The acquired seedlings are strong and healthy; leaves ofthe seedlings are deep green; root systems of the seedlings are many, thick, and white; rootstocks are thick and strong, and the diameter of the rootstocks is above 0.4 cm; and the seedlings grow vigorously. The density of the seedlings is large, the yield of the seedlings is high in unit area, and the benefits are significant. Two scientific nutriment formulations are used, a reasonable nutriment proportion is provided for various growth stages of the seedlings, and various nutriment elements required by seedling growth can be ensured.

Description

technical field [0001] The invention relates to a large-scale seedling raising method using araceae seeds, and belongs to the technical field of modern Chinese herbal medicine cultivation. Background technique [0002] Tiannanxing is also known as Nanxing, Bainanxing and so on. Tubers oblate, 2-4 cm in diameter, flattened at the top, rooting around, often with some lateral bud eyes. Scale buds 4-5, membranous. The leaves are often single, the petiole is cylindrical, pink-green, and the lower 3 / 4 sheath is cylindrical; the leaves are divided like avian feet, with 13-19 lobes, sometimes less or more, oblanceolate. The inflorescence peduncle is 30-55 cm long, drawn out from the petiole sheath tube. Spatha tube cylindrical; eaves ovate or ovate-lanceolate. Spadix bisexual and male inflorescence unisexual. Bisexual inflorescences. Unisexual male inflorescences 3-5 cm long and 3-5 mm thick. Female flowers spherical, style conspicuous, stigma small. Male flowers stalked, an...
