Large-scale seedling culture method by spreading hedyotis herb seeds

Abstract

The invention provides a direct sowing and seedling culture method by spreading hedyotis herb seeds, and aims to solve the problems that a spreading hedyotis herb seedling culture method is high in young seedling disease affliction rate and cost and low in transplanting survival rate, seedlings are not strong or neat and the like. The spreading hedyotis herb seeds are subjected to the steps of nursery garden land selection, sowing time selection, low-temperature inducement treatment, shed setup and car opening, sowing density management, management before seedling emergence, early management after seedling emergence, mid-late management after seedling emergence, emerged seedling transplantation and the like. According to the method, spreading hedyotis herb seedling culture land selection requirements are standardized, land selection, land use and soil treatment are performed according to regulations, emergence rate is high, the young seedling disease affliction rate is very low, the seedling transplanting survival rate reaches 98% or more, seedling culture density is high, the seedling yield is high in unit area, and benefits are remarkable. Reasonable nutritive proportions are provided for various growth stages of young seedlings by two scientific nutrition formulas, various nutritional elements needed for growth of the young seedlings are ensured, the use efficiency of a greenhouse is improved, and production cost is reduced.

Description

technical field

[0001] The invention relates to a large-scale seedling raising method using Hedyotis diffusa seeds, and belongs to the technical field of modern Chinese herbal medicine cultivation. Background technique

[0002] Hedyotis diffusa is also called Hedyotis, Hedyotis, Snake Needle Grass, Snakehead, Erye Humulus, Daffodil Crossgrass, Sharp Sword Grass, Armor Grass, Agave Grass, Hedyotis, Hedyotis. It is an annual loose herb, 15-50cm high. Roots slender, branched, white flowers. Stem slightly square or oblate cylindrical, smooth and glabrous, much branched from base. Flowering in spring. Seeds brownish yellow, small, and 3 angular. Flowers are solitary or paired in leaf axils, often with short and slightly thick pedicel, sparsely sessile; calyx is simple spherical, 4-lobed, lobes oblong-lanceolate, 1.5-2mm long, with eyelashes on the edge; flowers 4, Single or twin in leaf axils; pedicel slightly stout, 2-5mm long, rarely sessile or occasionally 10mm long; coro...

Embodiment 1

[0032] Choose 0.5 mu of sandy loam on the newly opened up land from east to west, 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, 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. Treat at a low temperature of 3-8°C for 30 days, wash the seeds with freshly drawn well water, and remove the deflated seeds. Before planting, soak the Hedyotis diffusa seeds in a solution of 100ppm gibberellin + 500 times carbendazim + 1000 times thiophanate-methyl at 25°C for 1 night (12 hours), drain the water, mix in river sand with 10 times the amount of seeds, Mix the river sand and seeds evenly and then put them into the mixer for grinding for 40 minutes.

[0033] Spread 5cm thick new mix soil on the car surface (new land reclamation soil: 1:1 ratio of sieved river sand), level it, sow 5kg evenly, cover...

[0036] Choose 0.5 mu of sandy loam on the newly opened up land from east to west, 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, 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. Treat at a low temperature of 3 to 8°C for 35 days, wash the seeds with freshly drawn well water, and remove the deflated seeds. Before sowing, soak Hedyotis diffusa seeds in 100ppm gibberellin + 500 times carbendazim + 1000 times thiophanate-methyl solution at 25°C for 1 night (12h), drain the water, mix in plant ash with 10 times the amount of seeds, and The sand and seeds are mixed evenly and then put into the mixer for grinding for 40 minutes.
