Embodiment Construction

[0010] 100 days before planting, choose 50 catties of potato pieces with a single potato weight of 200-300 grams, neat and uniform, no pests, and no wounds as seeds;

[0011] Seedlings are planted in a 1-meter-wide seedbed and covered with plastic film. When the length of the potato seedlings grown from the potato pieces reaches 25-30 cm, the seedlings are artificially planted and propagated, and when the number of nodes of the artificial seedlings reaches 6-10 nodes Carry out topping and topping to promote branching;

[0012] 5-8 days before planting, thinly apply quick-acting nitrogen fertilizer to cultivate tender and strong seedlings. When the length of potato seedlings reaches 25-30 cm, cut the first section of tender and strong seedlings as seedlings, and keep the head within 5 cm when cutting seedlings. Several branches of the tree, to promote new seedlings, so that the seedlings are cut circularly.

Abstract

The invention discloses a seedling culture technology of sweet potatoes. The seedling culture technology is characterized by comprising the following steps of: selecting potato blocks with proper size, order, infirmity, no diseases and pests and no wound as seeds about 100 days before interposing; seeding and culturing the seedlings on a seed bed; covering plastic films; carrying provisonal planting and seedling breeding when the length of potato seedlings of the potato blocks reaches 25-30 cm; pinching, topping and promoting branching when the section number of provisonal planting seedlings reaches 6-10 nodes; faintly fertilizing rapid-effect nitrogen fertilizer for culturing tender seedlings and strengthening the seedlings 5-8 days before planting; shearing and picking a first section of tender sound seedlings as planting seedlings when the length of the potato seedlings reaches 25-30 cm; leaving a plurality of branches within 5 cm during shearing the seedlings to promote the seedlings to spout again; and in this way, circularly shearing the seedlings. The invention solves the problems of low yield and poor quality of the traditional sweet potato seedling culture mode and is applicable for high-yield seedling culture of colorful sweet potatoes.

Description

technical field [0001] The invention relates to the field of crop-sweet potato seedling raising, in particular to a high-yield seedling raising technology of colorful sweet potato. Background technique [0002] At present, the method of accelerating germination and picking buds by covering potato pieces with sandy soil is generally used in the cultivation of colorful sweet potato seedlings, and the yield of seedlings is low and the quality is poor. Contents of the invention [0003] In order to solve the problems of low seedling yield and poor quality in the current way of raising seedlings of colorful sweet potatoes, the invention invents a high-yield seedling raising technology of colorful sweet potatoes. [0004] The present invention is for solving above-mentioned technical problem, and the adopted technical scheme is, a kind of colorful sweet potato seedling raising technology, and its special feature is: [0005] About 100 days before planting, choose potato cubes o...
