Embodiment 1

[0016] The method of raising sweet potato seedlings in autumn, winter multiplication and spring transplanting includes the following steps: choose a place that is leeward to the sun, convenient for irrigation and drainage, loose in soil quality and has not been planted with sweet potatoes in the past three years to build a greenhouse, apply compound fertilizer 10 days before the seedlings, and deeply plow the land in the greenhouse. Rotary tillage and leveling, make a 1.5-meter-wide furrow based on the greenhouse, form a 25cm soil ridge between the furrows, step on it, climb the loose soil in the middle of the furrow to the ridge, and apply potassium sulfate 10 days before seedling raising (15:15:15) compound fertilizer, deeply plow the land in the greenhouse, and level it with rotary tillage to make a 1.5-meter-wide furrow based on the greenhouse. A 25cm soil ridge is formed between the furrows. , Climb the loose soil in the middle of the furrow to the ridge. Before digging sw...

Abstract

The invention discloses a sweet potato autumn seedling winter propagation and spring cutting seedling raising method in the technical field of sweet potato planting. The sweet potato autumn seedling winter propagation and spring cutting seedling raising method comprises the steps that S1, a greenhouse is built; S2, soil preparation and ridging are conducted; S3, seedlings are prepared; S4, transplanting is performed; and S5, a seedbed is managed. According to the sweet potato autumn seedling winter propagation and spring cutting seedling raising method, before sweet potatoes are harvested, robust vine seedlings without insects and diseases are directly selected and reused as second-crop seedlings, a special greenhouse is adopted, heat can be collected or dissipated according to requirements, and the proper temperature is kept in the greenhouse; water or fertilizer mixed with water can be applied to leaf surfaces, underground irrigation is carried out, and illumination is supplemented; seedling growth can be accelerated through seedbed management, sweet potato seedling breeding can be greatly improved through film uncovering and seedling hardening, and a series of comprehensive methods can improve the seedling emergence number of the sweet potatoes, reduce the number of generations, reduce the diseases and pests and improve the quality of sweet potato seedlings and the survival rate of transplanting; the growth of vines is accelerated, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the technical field of sweet potato planting, in particular to a method for raising sweet potato seedlings in winter and spring. Background technique [0002] Sweet potato is also known as sweet potato, sweet potato, red potato, golden potato, fanru, red yam, jade pillow potato, sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, sweet potato, a goose, and cute sweet potato. Annual herbaceous plant, with round, oval or spindle-shaped root tubers in the underground part, flat or ascending stems, occasionally twisted, multi-branched, leaf shape and color vary with different varieties, usually broad ovate, petiole length Different, cymes axillary, capsule ovate or oblate, seeds 1-4, usually 2, glabrous, when the existing sweet potato seedlings are raised, due to plant diseases and insect pests and improper seedling raising methods, it is easy to cause sweet potato seedlings to grow. The quality and survival rate...
