Embodiment 1

[0017] A method for raising seedlings of sweet potatoes with high yield, characterized in that said method for raising seedlings comprises the following steps:

[0018] (1) Cultivation soil pretreatment: select nutrient-rich soil, use carbendazim wettable powder and pentachloronitrobenzene as a 3:1 disinfectant, spray it on the soil at an amount of 100g / cubic soil, and Watering, keeping the moisture content at 65%, stuffy for 4 days;

[0019] (2) Nutrient fertilizer: take the wheat bran passed through a 20-mesh sieve, pass through a 3cm sieve, mulch leaf soil and decomposed manure according to the composition of 3:2:2, stir evenly, and sprinkle it into the cultivation soil layer;

[0020] (3) Seed pretreatment: Soak the seeds in clean water, take the plump seeds that sink to the bottom of the water and put them in 45% phoxim granule 800 times solution and soak for 12 minutes;

[0021] (4) Sowing: Keep the water content of the culture soil at 65%, sow at a density of 1600 grai...

Abstract

The invention discloses a high-yield seedling cultivation method of sweet potatoes. The method is characterized by comprising the following steps: 1, cultivation soil pretreatment; 2, nutrition fertilizer manufacturing; 3, seed pretreatment; 4, seeding. According to the method, by replenishing the nutrition required by the growth of the sweet potatoes and pretreating seeds, the environmental conditions for the growth of the sweet potatoes are further guaranteed, the emergence rate and survival rate are high, seedling bodies are strong, the yield is high, the control over various conditions of the method is easy to achieve, the operation is simple, the method is applicable to the areas which are cold in winter, and the market application prospect is broad.

Description

technical field [0001] The invention belongs to the technical field of seedling raising, and in particular relates to a method for raising sweet potato seedlings with high yield. Background technique [0002] The sweet potato root is fleshy, hypertrophic, conical or spindle-shaped, up to 10 cm in diameter, with light yellow skin, rich in fibrous, easy to peel off, white flesh, sweet and juicy. The stem is twisted, 3-8 meters long. Compound leaves, alternate; leaflets 3, top leaflet diamond-shaped, 3.5-16 cm long, 5.5-18 cm wide, leaflets on both sides, ovate or diamond-shaped, 3.5-14 cm long, 3-13.5 cm wide, with teeth on the edge, Or palmately split, rarely entire. [0003] Sweet potato is a high-yield and stable crop. It has the characteristics of wide adaptability, strong stress resistance, drought and barren resistance, and less pests and diseases. It is planted in places with good water and fertilizer conditions. Generally, the yield per mu of spring potato can reach ...
