At present, the harvest of fresh ginger has a large number of listed, but now the price has dropped to three or four yuan per kilogram, many farmers are not willing to sell, to choose the storage of ginger. However, there are many diseases and insect pests of ginger during storage, and if they are not prevented and controlled in time, it will cause no small loss.
There are two ways to store ginger in storage and storage in cold storage. Many farmers have their own ginger cellar, the main form of soil cave, wells, crypt, brick cellar. In order to prevent infection, ginger should be selected strictly. Any ginger used for storage should be made of strong ginger with regular size, good quality and no disease. It should be rid of cold, injured, dry, sick and rained ginger. At the initial stage of storage, the respiration of the ginger is strong and the temperature in the cellar is high. Do not close the cellar immediately and keep the ventilation in one stage. Early storage of ginger crisp, easy peeling, required temperature is maintained at 20 DEG C, Jiaokou placed shade to prevent sunlight.
Ginger plague is an important disease in the storage process of ginger. It is a contagious storage disease, and once the condition is suitable, it begins to spread. The sick ginger is dark and shiny and has a dark heart. The deeper the color is, the heavier the disease is. Prevention and control method: after harvest, if the weather is good, it should be put in the sun for 1-2 days, killing germs and drying the skin. Let the ginger evaporate a little more water, in order to prevent heat and decay after excessive water entry into the cellar. During the period of storage, it should be checked at any time to find that the pathogenic ginger is cleaned in time so as not to be contagious.
Mycosis causes a layer of black patches or rotten skin on the surface of ginger, which is especially easy to occur when the tuber is injured and the environment is suitable. With the development of the disease, mildew and melanospora gradually infiltrated into the tuber. Control method: Advance in disinfection storage pits, disinfection methods are commonly used in pits and smoked a certain amount of lime applied two methods, simple and easy, the effect is very good.
In addition, cold injury should be prevented during the storage of ginger. During the storage, the cold and hot air is uneven, the ventilation is improper, the cold air suddenly enters the storage room, and it is easy to freeze the ginger. After the cold damage, ginger is easy to go out of water and quickly rotted and rotted. Prevention and control methods: pay attention to the change of the weather and strengthen the measures of freezing and keeping warm. The minimum temperature dropped to 8 degrees Celsius, the ginger pit covered with grass thatch insulation, began to cover 5-7 cm thick, with the temperature decreased gradually thickened, finally covered with mud, ensure ginger winter safely.
The main insect pest of ginger is mycosis mycosis. The survey found that because the farmers were in a hurry to harvest ginger, some of the soil left on the surface of ginger blocks may carry the heterotypic mushroom. In addition, the way of ginger entering the pit is backward. The storage way of ginger is simple, which makes the occurrence of heterotypa mosquitoes in well cellar. In the pit, the perennial temperature is at 15 -20 C, which is suitable for the occurrence of mycosis mycosis. The larvae bite the ginger, resulting in the decay of the affected part and the loss of commodity value.
In order to prevent and control the heterotypic mushroom, we must first find and destroy the plants that are damaged by the mushrooms in the field, and avoid bringing them into the well cellar when harvesting. Two, we should do well the cleaning and spraying disinfection of well cellars ahead of time. The use of 1.8% abamectin emulsion for 15 kg of water, evenly sprinkled in the pit of the sand and wall, wet. In addition, we should also pay attention to the arrangement of the cellar in the ginger, which is suitable for a layer of fine sand with a layer of ginger. Three, after the pits are finished, we should cover the insect proof net or seal the dead cellar to prevent the adult from flying into the spawn.
