Embodiment 1

[0018] A method for raising sweet potato seedlings with high survival rate, the steps are as follows:

[0019] 1) Choose disease-free and harmless autumn-harvested potato roots as seed potatoes, place the seed potatoes in rice bran and bury them until 1 day before seeding. After taking them out, soak them in hot water at 50±2°C for 5 minutes, and then place them in hot water. Add brassinolide into the water, continue to soak for 3-5 minutes, take it out, put it into the compound plant ash powder and roll it directly, so that the surface of the seed potato is covered with a thin layer of compound plant ash powder;

[0020] 2) Choose a leeward sunny, flat, well-drained plot to build a seedbed, the seedbed includes a top-down surface layer, a composite soil layer, a nutrient soil layer, a loose heating layer, and an isolated bottom layer. The total thickness of the seedbed is 30-40cm;

[0021] 3) Transplant the seed potatoes on the seedbed, and arrange the seeds on an incline to...

Abstract

The invention provides a high-survival-rate sweet potato seedling breeding method. The method includes the steps of selecting and storing potato seeds, taking out the potato seeds one day before row planting to be placed in hot water at 50+ / -2 DEG C to be soaked for 5 min, adding brassinolide to the hot water, continuing to soak the potato seeds for 3-5 min, and taking out the potato seeds to be directly placed in composite plant ash to be rolled so that the surface of each potato seed can be covered with a thin layer of composite plant ash; selecting a land to construct a seedling bed, wherein the seedling bed comprises a surface layer, a composite soil layer, a nutrient soil layer, a loose heating layer and an isolation bottom layer from top to bottom, and the total thickness of the seedling bed is 30-40 cm; transplanting the potato seeds on the seedling bed to plant the potato seeds in rows obliquely with a sunny exposure, covering and sealing the potato seeds with a film tightly, keeping the temperature in the film at 33-34 DEG C, lowering the temperature to 25-27 DEG C after germination, and moving seedlings to a large field to be planted and inserted when the seedlings grow to be 15-20 cm long, wherein the potato seed spacing is 3-4 cm, the row planting amount of 10-12 kg / m<2>, and the weight of each potato seed is 500+ / -50 g. Through the reasonable potato seed processingand seedling bed arranging, the germination rate and neat rate of sweet potatoes are effectively increased, the seedlings are healthy and robust, and the after-transplanting survival rate is larger than 99.5%.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to a method for raising sweet potato seedlings with high survival rate. Background technique [0002] Sweet potato, scientific name sweet potato, also known as sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, thread sweet potato, white potato, golden potato, sweet potato, red potato, pillow potato, sweet potato, white taro, fennel sweet potato, Red-skinned sweet potatoes, yams, sweet potatoes, etc. Sweet potatoes are rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals. They have the reputation of "longevity food". Their sugar content reaches 15%-20%. Emphysema, diabetes, weight loss, etc., especially for senile constipation. In Ming Dynasty Li Shizhen's "Compendium of Materia Medica" recorded "sweet potato tonic, invigorating spleen and appetizing, strengthening kidney yin", and said tha...
