Embodiment 1

[0024] A method for cultivating sweet potatoes, comprising the steps of:

[0025] 1) Select seed potatoes

[0026] 16 days before planting, select seed potatoes, choose seed potatoes with no wounds, fresh skin color, no cracks, no disease spots, and many bud eyes, and remove deformed, cracked, bud eye necrosis, and potato pieces with disease spots;

[0027] 2) Germination

[0028] Use loam to germinate indoors at a room temperature of 17°C, one layer of soil and one layer of seed block, and sprinkle water twice during the germination period to prevent it from drying out.

[0029] 3) cut into pieces

[0030] Cut into pieces when the buds are exposed about 0.5cm, and the pieces should be evenly cut to ensure that each piece has 2 strong buds, and the weight of each piece of seed potato is 35g; the cut surface of the pieces is evenly smeared with 1% potassium permanganate for disinfection .

[0031] 4) Chemical treatment

[0032] Put the cut potato pieces into 200 times 40% ...

Abstract

The invention discloses a method for cultivating sweet potatoes, which comprises the following steps: 1) selecting seed potatoes; 2) accelerating germination, using loam to accelerate germination in a house at a room temperature of 16-19°C, with one layer of soil and one layer of seed blocks; 3) cutting into pieces, when When the germination is about 0.5-1cm, cut into pieces, and the pieces should be evenly cut to ensure that each piece has 2-3 strong buds, and the weight of each piece of seed potato is 35-45g; 4) chemical treatment, the cut potato Put the block into 40% formalin 200 times solution, soak for 5-8 minutes, remove, drain and dry in the shade; 5) Sow seeds, in late April, when the temperature is stable at 6-8°C, the ground temperature at 6-10cm of soil is Sow seeds in time at 8-12°C; improve the survival rate of sweet potatoes, enhance the benefits of planting sweet potatoes, enhance the disease resistance and insect resistance of sweet potatoes, achieve high yield and high quality, and have great promotion value.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and more specifically, the invention relates to a method for cultivating sweet potatoes. Background technique [0002] Sweet potato belongs to Tubular Flowers, Convolvulaceae annual herbaceous plant, more than 2 meters long, lying flat on the ground and slanting upwards, the leaves are usually wide ovate, 4-13 cm long, 3-13 cm wide, corolla pink, white, pale Purple or purple, bell-shaped or funnel-shaped, 3-4 cm long, capsule ovate or oblate, with pseudo-septum, divided into 4 chambers, with underground tubers, tubers spindle-shaped, outer skin khaki or purple-red. Sweet potatoes are rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals, and are known as "longevity food". The sugar content reaches 15% to 20%. It has anti-cancer, heart protection, prevention of emphysema, diabetes, weight loss and other effects. Li Shizhen's "Compendium of Materia Medica" in...
