Embodiment 1

[0020] A method for raising seedlings of soybeans sown in autumn, comprising the following steps:

[0021] (1) In autumn, take out the stored high-quality soybean seeds, lay them flat in the sun with a shading degree of 30%, dry them in the sun for 4 hours, then wrap them with double-layer wet gauze at a temperature of 30°C, and keep them warm under dark conditions 10 hours, during which the prepared solution was sprayed once every 2 hours. The dosage was based on the wetness of the surface. The prepared solution was prepared from Chinese herbal medicine boiled liquid, plant growth hormone, trace elements, surfactants, and water;

[0022] (2) After the seeds are treated, mix them with dry nutrient soil. The weight ratio of the seeds to the nutrient soil is 1:0.5. Sow in the seedling field after fertilization and intensive cultivation. The seeding density is based on the seed spacing of 2.5-3.0 cm After sowing, sprinkle fluffy mixed soil on the surface of the nursery ground, co...

Embodiment 2

[0031] A method for raising seedlings of soybeans sown in autumn, comprising the following steps:

[0032] (1) In autumn, take out the stored high-quality soybean seeds, lay them flat in the sun with a shading degree of 35%, dry them in the sun for 5 hours, then wrap them with double-layer wet gauze at a temperature of 33°C, and keep them warm under dark conditions 11 hours, during which the prepared solution was sprayed every 2 hours, and the dosage was based on the wetness of the surface. The prepared solution was prepared from Chinese herbal medicine boiled liquid, plant growth hormone, trace elements, surfactants, and water;

[0033] (2) After the seeds are treated, mix them with dry nutrient soil. The weight ratio of seeds to nutrient soil is 1:0.55. Sow in the seedling field after fertilization and intensive cultivation. The seeding density should be within the range of 2.5-3.0 cm. After sowing, sprinkle fluffy mixed soil on the surface of the nursery ground, cover with ...

Embodiment 3

[0042] A method for raising seedlings of soybeans sown in autumn, comprising the following steps:

[0043] (1) In autumn, take out the stored high-quality soybean seeds, lay them flat in the sun with a shading degree of 40%, dry them in the sun for 6 hours, then wrap them with double-layer wet gauze at a temperature of 35°C, and keep them warm under dark conditions 12 hours, during which the prepared solution was sprayed once every 2 hours. The dosage was based on the wetness of the surface. The prepared solution was prepared from Chinese herbal medicine boiled liquid, plant growth hormone, trace elements, surfactants, and water;

[0044] (2) After the seeds are treated, mix them with dry nutrient soil. The weight ratio of seeds to nutrient soil is 1:0.6. Sow in the seedling field after fertilization and intensive cultivation. After sowing, sprinkle fluffy mixed soil on the surface of the nursery ground, cover with a thickness of 0.6 mm, carry out fine tillage, sprinkle irriga...

Abstract

The invention relates to the technical field of agricultural planting and discloses a seedling culture method for autumn-sowing soybeans. The method has the advantages that the drought and cold resistance of processed seeds can be increased, the root system of soybean seedlings can be optimized, the proportion of fibrous roots and lateral roots in total root length is increased, absorption of moisture and nutrition in soil is benefited, net photosynthetic rate is increased, and a sowing management method can guarantee high germination rate and neat seedling emergence; after the autumn and winter, the cultured soybean seedlings are simple in seedling management, robust seedlings can be cultured favorably, seed use amount can be reduced by 15-20%, yield can be increased by 18-25%, and accordingly labor productivity and economic benefits can be increased greatly.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for raising seedlings of soybeans sown in autumn. Background technique [0002] Soybeans, commonly known as soybeans. Fabaceae soybean is an annual herb, 30-90 cm high. The stem is stout, erect, densely covered with brown long bristles. The leaves usually have 3 leaflets, the stipules have veins, are yellow pilose, the petiole is 2-20 cm long, the leaflets are broadly ovate, papery, the racemes are short and less flowered, and the long ones are many flowers, the total pedicel usually has 5 -8 sessile, tightly packed flowers, bracts lanceolate, strigillose, bracteoles lanceolate, appressed setae, calyx lanceolate, flowers purple, lavender or white, petaled at base Stem, petals castrate. The pods are hypertrophic, slightly curved, drooping, yellow-green, densely covered with brown-yellow long hairs; 2-5 seeds, oval, nearly spherical, with smoo...
