Embodiment Construction

[0013] A method for raising seedlings of sweet potatoes, comprising the following steps:

[0014] (1) Select sweet potatoes with smooth surface, no tumors, complete skin, and a size of 0.5-1kg. Wash the surface of the sweet potatoes and treat them with Bordeaux mixture and 2.5% gibberellin for 10 minutes respectively. The Bordeaux mixture is copper sulfate, quicklime, water According to the weight ratio of 1.5:1:200, it can effectively prevent insects and promote the germination and rooting of sweet potatoes;

[0015] (2) Clean up the soil, apply 500kg of farmyard manure, 0.5-0.8kg of ammonium molybdate, 0.2-0.5kg of borax, and 200-250kg of river mud per mu to make ridges with a width of 25-40cm and a distance of 15-20cm. Ridge height 15-20cm;

[0016] (3) After the soil in step (2) has been treated for one month, bury the sweet potatoes in the prepared soil and plant them in ridges with a depth of 10-15cm, and the distance between adjacent sweet potatoes is 20-30cm. The sur...

Abstract

The invention relates to a sweet potato seedling-raising method comprising the following steps: (1) sweet potatoes with smooth surfaces, no nodule, complete surface skins, and sizes of 0.5-1kg are selected; the surfaces of the sweet potatoes are washed, and the sweet potatoes are respectively treated for 10min by using a Bordeaux mixture and 2.5% gibberellin; (2) soil is prepared; (3) after 1 month of soil preparation in the step (2), the sweet potatoes are buried in the prepared soil, and are planted according to ridges; and (4) after the sweet potatoes are germinated, holes for the sprouts to stretch are tore on mulches at places corresponding to the sprouts; and when sweet potato sprouts grow to a length of 40-60cm, transplanting is carried out. The sweet potato seedling-raising method provided by the invention is simple. Sweet potatoes are used for raising seedlings, such that the method is simple, and raw material source is rich. Sweet potato germination rate is high, and sweet potato growth is fast after germination. After planting, sweet potato seedlings have high survival rate and fast growth speed.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a method for raising seedlings of sweet potatoes. Background technique [0002] Sweet potato, also known as sweet potato, sweet potato, sweet potato, etc., is rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals. It has the reputation of "longevity food". Therefore, the price of this humble food is steep. The increase is impressive. Sweet potato is an annual plant of Convolvulaceae, a trailing herb, more than 2 meters long, lying flat on the ground and slanting upwards, with underground tubers, spindle-shaped tubers, and khaki or purple-red outer skin. Sweet potatoes are rich in starch, vitamins, cellulose and other essential nutrients for the human body, as well as mineral elements such as magnesium, phosphorus, calcium, and linoleic acid. These substances can maintain the elasticity of blood vessels and are very effective in preventing and...
