Problems solved by technology

[0003] Because sweet potatoes have strict requirements on temperature and humidity during storage, mildew is prone to occur if they are not careful, causing economic losses to growers. The existing technology mostly uses the lime powder method for storage in the cellar. However, lime powder heats up after absorbing water, which is easy to cause environmental pollution Temperature fluctuations are not conducive to the storage of sweet potatoes, causing mildew and rot during storage

Embodiment Construction

[0011] 1. the overwintering storage method of sweet potato is characterized in that comprising the following steps:

[0012] (1) Preparation before storage: build a storage room, use the cellar storage method, and use 50% carbendazim wettable powder 1500 times liquid to fully disinfect the cellar before storage, and prepare coarse river sand, plant ash, and rice straw. After sterilizing the rough river sand and rice straw with 50% carbendazim wettable powder 1500 times liquid, expose to the sun for 7-10 days, prepare temperature measuring equipment and humidity measuring equipment, and remove mildew and rot in sweet potatoes that need to be stored individual, put it in a ventilated place to dry for 5-8 days;

[0013] (2) Storage: When storing, lay coarse river sand on the bottom of the cellar with a thickness of 10-15cm, rice straw on the coarse river sand with a thickness of 5-6cm, plant ash on the rice straw with a thickness of 2-3cm, and place sweet potatoes On the plant a...

Abstract

The invention discloses an overwintering storage method for sweet potatoes. As sweet potatoes have strict requirements on temperature and humidity in a storage process, and are easily mildewed to cause economic loss to a grower in case of any carelessness, in the prior art, a method of storage with lime powder in a cellar is most frequently adopted, but lime powder produces heat to easily cause environmental temperature fluctuation after absorbing water, which is bad for the storage of sweet potatoes and easily causes mildewing and rotting in the storage process.

Description

technical field [0001] The invention relates to the field of agricultural product storage, in particular to a winter storage method for sweet potatoes. Background technique [0002] Sweet potato is the main food crop in my country. It has high calorie content and is rich in vitamins, minerals and cellulose. Now sweet potato is widely recognized as a good health product. In recent years, the planting area of ​​sweet potato in my country has risen steadily. Among them, safe storage is an important link to ensure production. [0003] Because sweet potatoes have strict requirements on temperature and humidity during storage, mildew is prone to occur if they are not careful, causing economic losses to growers. The existing technology mostly uses the lime powder method for storage in the cellar. However, lime powder heats up after absorbing water, which is easy to cause environmental pollution Temperature fluctuations are not conducive to the storage of sweet potatoes, causing mil...
