Description

A kind of implantation methods of sweet potato

Technical field

The present invention relates to a kind of implantation methods of crop, specifically a kind of implantation methods of sweet potato belong to industrial crops kind Planting technology field.

Background technology

Sweet potato is a kind of complete and abundant natural nourishing food of nutrition, and edible sweet potato has long history in China, Investigated according to archaeologist, early in people before more than 4,000 years just using sweet potato as conventional food.It is special containing abundant in potato wedges Different vitamin C, vitamin E and potassium element etc., wherein Vc can significantly strengthen the resistances of human body viruses various to flu etc. Power；Dimension E can then promote sexual desire, the anti-aging of people, and potassium element can effectively prevent the hair of hypertension, apoplexy and cardiovascular disease Raw, sweet potato has medical value higher.

With the development in epoch, sweet potato is also being improved at leisure because of its ecosystem, the advantage of health, its economic worth, mesh The preceding implantation methods just to the sweet potato of various novel tastes are studied.

The content of the invention

It is an object of the invention to provide a kind of implantation methods of sweet potato.

The present invention is achieved by the following technical programs：A kind of implantation methods of sweet potato, comprise the following steps：

S1, seed selection：According to situations such as sweet potato plantation level and market sale, to select in good taste, be adapted to directly edible and cook, Yield sweet potato kind high；

S2, seedbed selection and arrangement：Seedbed selection is leeward on the sunny side, soil layer is deep, the soil is porous, fertile soil, plot is smooth, lean on The irrigation and drainage of nearly water source are convenient, the plot rich in organic matter, never cross plot from sweet potato continuous cropping, 1 month ahead of time preparing nursery bed ground, enter Row site preparation, shine ground, plough deeply, carefully harrow, leveling, seedbed bottom spread one layer of organic fertilizer, be then covered by fine earth, cover plastics after pouring water It is thin；

S3, nursery：Potato seed wants vivid smooth, the potato wedges straight uniform of selected color of the leather, no disease and pests harm, without disability, do not received damage to plants caused by sudden drop in temperature, Wet injury, the consistent potato wedges of kind, single potato weighs 100~200 grams, using flat planting or tiltedly broadcasts, and seeding row spacing 10cm × 25cm educates at the beginning of 4 months Seedling, when seedling grows to 25~30cm, carries out heeling in numerous seedling, and carries out pinching when seedling joint number is heeled in up to 6~10 section positions and pinch Promote branch, when potato seedling growth length is up to 25~30cm, cuts and adopt the tender strong sprout of first paragraph and make seedling, should be kept here during cutting seedlings whole in 5cm Branch；

S4, selects seedling：Selection strong sprout, reject weak seedling, it is desirable to blade plumpness, color depth, grow top it is thick, internode is short, stem is sturdy, nothing The root system that pest and disease damage symptom, basal part of stem send is thick, delicate, and potato seedling growth length is 20~30cm, and whole strain is not not tender and crisp also aging；

S5, seedbed management：28~30 DEG C of bed temperature is kept before emerging, 25 DEG C of bed temperature is controlled after emerging, potato seed is sprouted recession and removes mulch film Applied fertilizer, topdressed for the second time when 10~13 centimetres of height of seedling, poured with night soil or composite fertilizer and applied, potato seedling growth is long 20~25 lis Rice, when there are 6~8 intact leafs, crop field can be planted with cutting seedlings；

S6, crop field selection：The preferable plot of selection soil texture is planted, and the deep ploughing of soil, depth are carried out in fine day 30cm, does not exceed 40cm, coordinates when ploughing deeply and spreads fertilizer over the fields organic fertilizer, and ridging treatment is carried out after deep ploughing, and ridge spacing is uniform during ridging；

S7, field planting：Mid-May, when soil moisture is suitable can field planting, during field planting seeding row spacing 23~25cm or 25~28cm it Between, 2500~3000 plants every mu；

S8, the prevention and control of plant diseases, pest control：It was found that aphid is sprayed from 10% imidacloprid, 1500 times of liquid, find leaf folder, chafer with 48% pleasure This this EC, it is found that prodenia litura is sprayed with 0.5% emamectin benzoate, 1500~2000 times of liquid, or 1000 times of 47% Le Siben missible oil Liquid, or 20% meter of full suspending agent, 1000 times of liquid spraying preventing and treatings；

S9, harvests storage：Sweet potato 120~130 days after plant harvests, and results process will gently dig, with light packs, light fortune, gently unload, and prevents Potato skin and potato wedges are damaged, sweet potato Appropriate Storage 10~150C of temperature, relative humidity 85%~90%.

Compared to prior art, beneficial effects of the present invention：Sweet potato taste using present invention plantation is sweet, and nutrition is rich Richness, and the implantation methods are simple and easy to apply, it is easy to operate, efficient.
