Method for preserving sweet potato seedlings after long-distance transportation

Abstract

The invention discloses a method for preserving sweet potato seedlings after long-distance transportation, which comprises the steps of (1) cutting high-cut seedlings with the length of 25-35 cm fromdisease-free sweet potato seedlings in a sweet potato seedling breeding base to obtain sweet potato seedlings, each sweet potato seedling comprising top buds and side buds, and the cutting position being 25-35 cm away from the top buds; (2) removing old leaves of the sweet potato seedlings, making a bundle with each 100 seedlings, and spreading and placing the sweet potato seedlings in a temporarystorage place for waiting for transportation if the sweet potato seedlings are not transported immediately, the temporary storage place being a cool, ventilated, dried and light-proof place. According to the method, the steps of sweet potato seedling collection, seedling transportation, preservation after seedling transportation and the like are researched, the method for preserving the sweet potato seedlings after long-distance transportation helps greatly increase the survival rate of the sweet potato after long-distance transportation, sufficient preparation time is provided for next planting, and the practical problems are effectively avoided that, for instance, the sweet potato loses water and wilts after long-distance transportation, cannot easily survive, and cannot be preserved.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to sweet potato seedlings, in particular to a method for preserving sweet potato seedlings after long-distance transportation. Background technique [0002] Sweet potato is an important food, feed, industrial raw material and energy crop, which has the characteristics of super high yield, resistance to barrenness, wide adaptability and easy recovery growth. In recent years, with the continuous improvement of living standards, people's diversified demand for sweet potatoes is also increasing, and the market potential of special-purpose sweet potato varieties is increasingly huge, and sweet potatoes are foods recommended by the World Health Organization, with rich processed products and more suitable Industrialization development and utilization. [0003] With the breeding of fine sweet potato varieties and the popularization and application of detoxification technology in many area...

AI Technical Summary

Problems solved by technology

The growth vigor of sweet potato seedlings is reduced after long-distance transportation. If they are directly planted, it will inevitably affect the survival rate and planting effect of sweet potato seedlings.

At the same time, in production practice, due to many objective reasons, the planting plan is often changed, and the potato seedlings cannot be planted in time, and the planting is temporarily stranded.
