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
The present invention relates to crops-pachyrhizus field of growing seedlings, specifically a kind of sweet potatoes seedling growing technology.
Background technology
At present, generally adopt sandy soil to cover the method for burying the vernalization of potato piece, adopting bud during sweet potatoes is grown seedlings, seedling yields poorly, and is of poor quality.
Summary of the invention
The present invention is for solving the seedling raising manners of present sweet potatoes, and seedling yields poorly, and ropy problem is invented a kind of sweet potatoes seedling growing technology.
The present invention is for solving the problems of the technologies described above, and the technical scheme that is adopted is, a kind of seedling culture technology of sweet potatoes, and its special character is:
In transplanting preceding about 100 days, select to be of moderate size (single potato weighs 200～300 grams), neatly the potato piece of even, anosis worm, no wound is planted;
Seedbed seeding at 1 meter wide is grown seedlings, and covers plastic film, when the potato seedling length that goes out when the potato block length reaches 25～30 centimetres, heels in numerous seedling, and carries out the pinching short branch of pinching when the seedling joint number reaches 6～10 joint positions heeling in;
5～8 days thin instant nitrogenousfertilizers of executing are cultivated tender seedling strong sprout before plantation, when potato seedling length reaches 25～30 centimetres, cut and adopt first period tender strong sprout and make seedling, several branches in 5 centimetres in the portion of letting the hair grow when cutting seedling, short its from the New Development seedling, so seedling is cut in circulation.
Technique effect
Because sweet potato is usually carried black spot, pine root fungus and nematodosis etc., the pathogen that carries in the potato piece can slowly move to potato bud top, the translational speed of pathogen is lower than the growth rate of potato bud, cut and adopt first section top seedling and can avoid the potato seedling to carry germ to a great extent, technique effect of the present invention is, adopt technique scheme, can realize a kind of sweet potatoes high-quality, seedling growing technology.
Specific embodiment
In transplanting preceding 100 days, select that single potato weighs 200～300 grams, neatly the potato piece of even, anosis worm, no wound is planted for 50 jin;
Seedbed seeding at 1 meter wide is grown seedlings, and covers plastic film, when the potato seedling length that goes out when the potato block length reaches 25～30 centimetres, heels in numerous seedling, and carries out the pinching short branch of pinching when the seedling joint number reaches 6～10 joint positions heeling in;
Before plantation 5～8 days, the thin instant nitrogenousfertilizer of executing was cultivated tender seedling strong sprout, when potato seedling length reaches 25～30 centimetres, cut and adopted first period tender strong sprout and make seedling, several branches in 5 centimetres in the portion of letting the hair grow when cutting seedling, short its from the New Development seedling, so seedling is cut in circulation.
Claims (1)
1. seedling culture technology of sweet potatoes, it is characterized in that: selected to be of moderate size in preceding about 100 days in transplanting, evenly neat, anosis worm, the potato piece of no wound is planted, seeding is grown seedlings in the seedbed, cover plastic film, when the potato seedling length that goes out when the potato block length reaches 25～30 centimetres, heel in numerous seedling, and reach 6～10 whens position joint and carry out the pinching short branch of pinching heeling in the seedling joint number, 5～8 days thin instant nitrogenousfertilizers of executing are cultivated tender seedling strong sprout before plantation, when potato seedling length reaches 25～30 centimetres, cut and adopt first period tender strong sprout and make seedling, several branches in 5 centimetres in the portion of letting the hair grow when cutting seedling, urge it from the New Development seedling, so seedling is cut in circulation.
