Breeding method of sweet potato seedlings

Abstract

The invention relates to the technical field of sweet potato seedling plantation, and especially relates to a breeding method of sweet potato seedlings. An incubator is cooperatively used for breeding the sweet potato seedlings, the carbon dioxide output of a carbon dioxide generator can be automatically adjusted according to the carbon dioxide concentration in a culture area by the incubator, and the enough carbon dioxide concentration can be ensured in the culture area. The optimum related indexes such as temperature, humidity, illumination intensity, the carbon dioxide concentration and oxygen concentration are provided for the culture area of the incubator by a single chip microcomputer cooperated with sensing devices such as a temperature sensor, a humidity sensor, a photosensitive sensor and an oxygen detector, automatic control is achieved, and the germination rate of sweet potato seedling seeds is satisfied to the maximum. In the culture area, a plurality of culture ports are also arranged, one seed is planted in one culture port, mutual interference of the seedlings during growth and transplantation processes can be prevented by adoption of the hill-drop-like planting mode, and germination of all of the sweet potato seedling seeds is ensured to the maximum.

Description

【Technical field】 [0001] The invention relates to the technical field of sweet potato seedling planting, in particular to a breeding method for sweet potato seedlings. 【Background technique】 [0002] Sweet potato (scientific name: Ipomoea batatas (L.) Lam.): Also known as sweet potato, sweet potato is the third largest food crop in Guangxi, with an annual cultivation area of ​​about 233,300 hectares. It is not only an excellent food and feed, but also has great prospects for development. Renewable energy crops. At present, in terms of sweet potato breeding and cultivating seedlings, the conventional method is to carry out outdoor, that is, use planting plots or nutrient cups to spread the seedlings of sweetpotato, and obtain seedlings after germination, and then transplant them. , Due to the inconsistent outdoor cultivation conditions, the seed seeds that are sown will germinate first, and some will germinate later, due to the different maturity. Yes, after being shaded, t...

Problems solved by technology

At present, in terms of sweet potato breeding and cultivating seedlings, the conventional method is to carry out outdoors, that is, to use planting plots or nutrient cups to sow sweet potato seedlings, obtain seedlings after germination, and then transplant them. , due to the inconsistency of various outdoor cultivation conditions, it will cause the sown seeds to germinate due to different degrees of maturity, some will germinate first, and some will germinate later. Yes, after being shaded, those that germinate last will grow very weakly, and may eventually die by themselves. There are also some that have not germinated, and basically cannot grow outdoors. According to statistics, if 1,000 seedlings are sown every year, only 150 seedlings can be obtained at most. - About 200 seedlings; therefore, it is necessary to provide a seedling cultivation method that can give all seedlings the best growth environment and ensure the germination rate of seedlings to the greatest extent
