Method for storing ginger without using pesticide

Abstract

The invention discloses a method for storing ginger without using pesticide. The method comprises the following steps of: removing sludge from the gingers and broken gingers; placing the gingers under the blazing sun for quite a long time until ginger epidermis is chapped and dried; cleaning a cellar neatly; performing sterilization and relative humidity control; placing the gingers into the cellar to pile up in a layered way, so that certain gaps are reserved among ginger blocks and the occupied area of the gingers is 3 / 4 to 5 / 6 of the cellar area; sterilizing yellow earth or fine sand; covering the yellow earth or the fine sand on the upper part of the whole ginger pile, wherein the periphery of the ginger pile is exposed; placing dried Chinese mugwort leaves and dried chillies on the open space of the cellar and burning the dried Chinese mugwort leaves and the dried chillies; and when the burned smoke ascends to the cellar opening, sealing the cellar opening, wherein the smoke generated by combustion of the dried Chinese mugwort leaves and the dried chillies has strong pungent smell and can poison ginger maggots in the gingers or the cellar, and the effective rate can reach over 97.5 percent, so that the gingers are prevented from being bitten by the ginger maggots, no decay spots or bugbite spots can be seen from the gingers, and quality of the gingers is guaranteed.

Description

technical field [0001] The invention relates to a drug-free storage method for ginger. Background technique [0002] Over the years, in order to store ginger well and sell it at a good price in the coming year, ginger farmers usually store the ginger in winter in the current year, which not only adjusts the market in low and peak seasons, but also sells them according to market conditions, and avoids market risks. [0003] Ginger has the characteristics of warm and cold, wet and dry. The suitable storage temperature is 10-15°C. Ginger below 10°C is prone to freezing damage, and ginger damaged by freezing is easy to rot after heating up. If the temperature is too high, diseases such as ginger rot will spread and the rot will be serious. The suitable relative humidity for storage is 90% to 95%. If the storage humidity is too high, it is conducive to the reproduction of germs and leads to corruption, but if the humidity is too low, it will cause ginger to lose water, shrink w...

Problems solved by technology

[0007] 666 powder is a highly toxic pesticide, which was banned by the state in the 1960s. Even so, this pesticide is still used by ginger farmers in large quantities in order to prevent ginger maggots from being bitten by ginger maggots during storage. The 666 powder is sprinkled between each layer of ginger. Due to the long-term attachment to the surface of the ginger, it will cause serious pesticide residues in the ginger and cause serious pollution to groundwater and the environment.
