Embodiment 1

[0026] Select plots with fertile soil, good drainage, convenient transportation and convenient management. It is strictly forbidden to select the land where sweet potatoes were planted in the previous year as seedling land to avoid mixing. Apply decomposed farmyard manure as base fertilizer, mix 600kg of farmyard manure per acre, then plow, crush the soil, and level the land, use a sweet potato ridger to start ridges, the distance between each ridge is 80cm, the height of the ridge is 30cm, and the width of the ridge top is 20cm. ~30cm,.

[0027] Cutting and pretreatment of sweet potato seedlings: select strong top seedlings with uniform and good growth as seedlings, cut 3-4 pieces from each plant, seedling diameter is 5-8cm, and seedling internode length is 3-5cm. The cut length of each sweet potato vine is 20-30 cm as a sweet potato seedling, so that the number of nodes of the obtained sweet potato seedling from the top is 7-8 as the criterion. Then add water to the zinc we...

Embodiment 2

[0032] Select plots with fertile soil, good drainage, convenient transportation and convenient management. It is strictly forbidden to select the land where sweet potatoes were planted in the previous year as seedling land to avoid mixing. Apply decomposed farmyard manure as base fertilizer, mix 700 kg of farmyard manure per mu, then plow, crush the soil, and level the land, use a sweet potato ridger to start ridges, the distance between each ridge is 100 cm, the height of the ridge is 30 cm, and the width of the top of the ridge is 20 cm. ~30cm,.

[0033] Cutting and pretreatment of sweet potato seedlings: select strong top seedlings with uniform and good growth as seedlings, cut 3-4 pieces from each plant, seedling diameter is 5-8cm, and seedling internode length is 3-5cm. The cut length of each sweet potato vine is 20-30 cm as a sweet potato seedling, so that the number of nodes of the obtained sweet potato seedling from the top is 7-8 as the criterion. Then add water to t...

Embodiment 3

[0037]Select plots with fertile soil, good drainage, convenient transportation and convenient management. It is strictly forbidden to select the land where sweet potatoes were planted in the previous year as seedling land to avoid mixing. Apply decomposed farmyard manure as base fertilizer, mix 650kg of farmyard manure per mu, then plow, crush the soil, and level the land, use a sweet potato ridger to start ridges, the distance between each ridge is 90cm, the height of the ridge is 30cm, and the width of the top of the ridge is 20cm. ~30cm,.

[0038] Cutting and pretreatment of sweet potato seedlings: select strong top seedlings with uniform and good growth as seedlings, cut 3-4 pieces from each plant, seedling diameter is 5-8cm, and seedling internode length is 3-5cm. The cut length of each sweet potato vine is 20-30 cm as a sweet potato seedling, so that the number of nodes of the obtained sweet potato seedling from the top is 7-8 as the criterion.

Abstract

The invention discloses a method for cultivating sweet potato seedlings, and the planting time is from the middle ten days of November every year to the June the next year. The method comprises the following steps that (1) a ploughed field is ridged; (2) preprocessing is carried out on shorn sweet potato seedlings, the sweet potato seedlings on every two adjacent ridges are planted oppositely, and then the sweet potato seedlings are watered; (3) when the outdoor temperature is lower than or equal to15 DEG C, a tunnel is built between every two adjacent ridges with bamboo sticks, the tunnels are covered with films, and the films are removed when the outdoor temperature keeps at 25 DEG C or above. Through the method for cultivating sweet potato seedlings, the planting time of spring sweet potatoes is advanced by 20-30 d compared with a potato block seedling cultivation method, the breeding frequency of sweet potato seedlings is increased, yield of the sweet potato seedlings is increased, cultivation of new species is further facilitated, a large number of seedlings can be cultivated within a short time through the method, and the application and popularization speed is improved. In addition, the method can improve the survival and growth capacity of sweet potatoes at low temperature and further improve the utilization rate of land.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for raising sweet potato seedlings. Background technique [0002] Sweet potato tubers are edible. It is native to tropical Central America. It grows vigorously, has high and stable yields, and is easy to breed and breed. It is widely planted in many areas of our country. Nowadays, the available arable land area in our country is gradually decreasing, the cultivation, breeding and physiological research of sweet potato are deepening, the agriculture and tourism industry are booming, and the health food of sweet potato is also emerging, so the attention of sweet potato is increasing in Chengdu. [0003] The cultivation of sweet potatoes is usually first to obtain potato seedlings by breeding tubers, stems, etc., and then plant the potato seedlings in the field. The top of the potato seedlings continues to elongate to form the main vines, and at the same time the axil...
