Problems solved by technology

[0008] The above three comparative documents provide three different sweet potato cultivation techniques. The sweet potato cultivation techniques provided by Comparative Document 1 and Comparative Document 2 all involve seedling cultivation. Seedling cultivation is easily affected by the weather environment. If seedling cultivation is not good, it is easy to cause insufficient seedlings. It is also difficult to control the time of planting. The control of planting density and time will affect the growth rate of sweet potatoes, thereby affecting the quality and yield of sweet potatoes. Sweet potatoes are uneven in size

Embodiment 1

[0047] Step (1): Select 5 catties of high-quality potato seeds (about 15 sweet potatoes). In order to ensure the germination rate of potato seeds and increase the seedling rate, it is advisable to choose sweet potatoes with a moderate size, neat and uniform, no pests, no wounds, and no chilling damage. as potato seed;

[0048] Lay the potato seeds flat, each potato seed connected at the first place to form a row, the distance between each row is controlled at 10-15 cm, 6-8 potato seeds form a ridge, and the ridge is arched with bamboo chips or steel frames and covered with film to keep warm. Then sprinkle with fertilizer and cover with a layer of soil;

[0049] The fertilizer specifically includes: 5 parts of plant ash; 4 parts of chicken and duck manure; 15 parts of potassium oxide; 5 parts of phosphorus pentoxide; 10 parts of urea.

[0050] Sweet potato is a potassium-loving crop. The main component of plant ash is potassium. It is an organic fertilizer rich in potassium, ca...

Embodiment 2

[0057] The difference with embodiment 1 is:

[0058] The fertilizer comprises: 8 parts of plant ash; 5 parts of chicken and duck manure; 25 parts of potassium oxide; 8 parts of phosphorus pentoxide; and 16 parts of urea.

[0059] Treat the potato seeds in the step (1) to germinate, the potato sprouts grow for 25 days, and prepare for transplanting when the potato sprouts grow to 10 cm potato seedlings.

Embodiment 3

[0061] The difference with embodiment 1 is:

[0062] The fertilizer comprises: 10 parts of plant ash; 6 parts of chicken and duck manure; 30 parts of potassium oxide; 10 parts of phosphorus pentoxide; 20 parts of urea.

[0063] Treat the potato seeds in the step (1) to germinate, the potato sprouts grow for 35 days, and prepare for transplanting when the potato sprouts grow to 15 cm potato seedlings.

Abstract

The invention discloses an efficient and high-yield sweet potato cultivation method. The method comprises the steps that potato seeds are subjected to flatwise seedling growing, and when potato seedlings with potato buds of the length of 10-15 cm grow from the potato seeds, transplanting is performed. The method comprises the steps that 1, high-quality potato seeds are selected, the potato seeds are flatwise placed, the heads and tails of the potato seeds are connected into a row, each row interval is not larger than 15 cm, and then, fertilizer is scattered and covered with a layer of soil; 2, after the potato seeds in the first step germinate, the potato buds grow for 25-35 d, and transplanting is prepared when the potato buds of the potato seedlings grow to 10-15 cm. The survival rate during sweet potato transplanting can be increased, the potato seed input amount per mu is decreased, the seedling growing time is shortened, the sweet potato growth period is prolonged, the yield and taste of sweet potatoes are improved, and the efficient and high-yield sweet potato cultivation method can reduce manual input during transplanting.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a high-efficiency and high-yield cultivation method of sweet potatoes, belonging to the technical field of plant cultivation. Background technique [0002] Sweet potato, formerly known as sweet potato, also known as sweet potato and sweet potato, belongs to the order Tubular Flowers and is an annual herb of Convolvulaceae. The leaves are usually wide ovate, 4-13 cm long, 3-13 cm wide, and the corolla is pink, white, lavender or Purple, bell-shaped or funnel-shaped, 3-4 cm long, capsule ovate or oblate, with false septum, divided into 4 chambers. Sweet potatoes are rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals, and contain 1.5%-5% sugar. They have anti-cancer, heart protection, emphysema prevention, diabetes, weight loss, and beauty effects. Known as "longevity food", it is a pollution-free green healthy food with both medicine and food. [0003] S...
