Embodiment 1

[0019] A cultivation method for vegetable sweet potato leaves, the specific steps comprising:

[0020] (1) Seedling treatment: In mid-October, select sweet potato stalks, place them in a low temperature environment of 4-6°C for 24 hours, and then transfer them to potassium permanganate solution for 10-20 minutes for disinfection;

[0021] (2) Seedling cultivation: the sweet potato stalk cuttage after processing in step (1) is placed in the socket tray of band substrate, is sterilized with carbendazim earlier, then covers a layer of film on the surface of the socket disk, after 5-7 days, in Build small arch supports on both sides of the hole plate, and cover the small arches with a layer of film and a layer of sunshade net in turn. After 5-7 days, the sunshade net will be opened and covered regularly every day for 4 days, and then regularly every day for 3 days. lift and cover the membrane on the small arches;

[0022] (3) Colonization: In mid-November, first use quicklime to ...

Embodiment 2

[0027] A cultivation method for vegetable sweet potato leaves, the specific steps comprising:

[0028] (1) Seedling treatment: In mid-October, select sweet potato stalks, place them in a low temperature environment at 5°C for 24 hours, and then transfer them to potassium permanganate solution for 15 minutes for disinfection;

[0029] (2) Seedling cultivation: Cutting the sweet potato stalks treated in step (1) in the plug tray with substrate, sterilized with carbendazim first, then covered the surface of the plug tray with a layer of film, and after 6 days, put it on the plug tray Build small arch supports on both sides, and cover the small arches with a layer of film and a layer of sunshade net in turn. After 6 days, the sunshade net will be opened and covered regularly every day for 4 days, and then opened and covered regularly every day for 3 days. film on the small arches;

[0030] (3) Planting: In mid-November, first use quicklime to disinfect the soil in the greenhouse,...

Abstract

The invention discloses a cultivating method of sweet potato leaves for a vegetable purpose. The method comprises the specific steps of seedling treatment (low-temperature treatment firstly and then immersion disinfection), seedling culturing (adding a small arch device to adjust the temperature), planting, transplanting, insulation treatment (adopting a technology of sleeving an inner greenhouse with an intermediate greenhouse and sleeving the intermediate greenhouse with an outer greenhouse) and harvesting. According to the cultivating method of the sweet potato leaves for the vegetable purpose, earlier stage processing of seedlings can ensure the quality of sweet potato stalks, and facilitates the subsequent development of the sweet potato stalks; the small arch design is added in the seedling culturing step, which facilitates the control over the temperature change in a hole disk and shortens the seedling culturing time; during the insulation treatment, the technology of sleeving the inner greenhouse with the intermediate greenhouse and sleeving the intermediate greenhouse with the outer greenhouse, which effectively improves the temperature in the greenhouses and can stably keep warm, and improves the growth and quality of the sweet potato stalks; meanwhile seedling culturing can be started from October, thus anti-season cultivating is achieved, 7-9 continuous batches can be harvested, and the economic benefit is greatly improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for cultivating vegetable sweet potato leaves. Background technique [0002] Sweet potato, also known as sweet potato, sweet potato, sweet potato, etc., belongs to the sweet potato species of the family Convolvulaceae and is an annual herb. Its sweet potato leaves have been widely loved by people as a vegetable, and sweet potatoes like high temperature and strong sunshine. Therefore, traditional sweet potato planting generally starts seedling cultivation in April, planting in May, and harvesting sweet potato leaves in late June for sale. Three crops can be harvested during this period, that is to say, only three crops can be harvested in a year. The growth period is long and the output is limited. At the same time, the cultivation area of ​​protected vegetables continues to expand, the investment in facilities continues to increase, and the cost of labor continues...
