Carrots are common vegetables in our daily life. They are delicious, sweet and delicious, and are very popular among people. The storage period after the harvest of carrots is especially important. This article will introduce the winter storage precautions for carrots and hope to help everyone.
First, the ditch
The storage ditch used for carrots is generally 1-1.5 m wide. If it is too wide, it will increase the influence of temperature, reduce the heat preservation effect of the soil, and it is difficult to maintain a stable low temperature in the ditch; the depth of the ditch should be slightly higher than that of the local winter frozen soil layer. The depth is 0.6-0.8 meters, and the length depends on the storage capacity. During the storage process, the thickness of the soil is adjusted to change the temperature in the trench as the ambient temperature changes.
The storage ditch should be located at a higher terrain, with a lower water level and a stronger soil and water retention capacity, and the east and west are extended. Generally, the subsoil is relatively clean, and there are few bacteria, which are used for covering. The surface mound plays a shading role on the south side of the ditch, and the mound is shaded to increase its height as much as possible. No additional materials are needed, and the temperature can be lowered and the temperature can be kept constant in the middle and middle stages of storage.
Carrots can be scattered in the ditch, and the thickness is generally not more than 0.5 meters, so as to prevent the bottom product from being rotted by heat. *** It is good to be layered with wet sand, which helps to protect the moisture and increase the concentration of carbon dioxide around the straight root. When the squat is smeared, a thin layer of soil is applied to the surface of the product, and then added with the temperature drop, and after ***, it is flush with the ground. It is necessary to master the period and thickness of each covering soil in case the underlying temperature is too high and the product is frozen or the surface product is frozen. In order to grasp the appropriate temperature conditions, a bamboo tube or a wooden tube can be placed in the middle of the ditch, and a thermometer is placed inside, and the temperature in the ditch is periodically observed in the carrot to cover in time. Most of the buried root vegetables are once out of the ditch. When the weather turns warmer in the next year, the soil is removed, and the rotting straight roots are picked out. The top buds are cut off and placed in the ditch, and a thin layer of soil is covered for a period of time.
Second, the stacking method
Carrots can be piled up or piled up in the raft or in the ventilation warehouse. The pile should not be too high. The general stack height is 0.8-1 meters, otherwise the temperature inside the pile is high and perishable. In order to enhance the ventilation and heat dissipation effect, a ventilator can be set every 1.5-2 meters in the stack. Generally, the pile is not piled up during storage. The use of wet sand in the raft or warehouse is better than the loose pile, which is easy to moisturize and accumulate carbon dioxide. Pay attention to the temperature inside the 窖 or the library, and cover it with a straw curtain if necessary to prevent freezing. Regular inspections during storage revealed that the decayed products were promptly removed.
Third, plastic film semi-closed storage method
In the ventilation warehouse, the carrots are stacked into a rectangular plaque of a certain size. The storage is started or the temperature of the storage is raised. The blister is covered with a plastic film cover. The bottom of the sputum is not covered with a film. The semi-closed state can appropriately reduce the oxygen concentration and increase the carbon dioxide level. Maintain high humidity, prolong storage, and better preservation effect. During storage, the ventilation can be periodically ventilated and checked if necessary.
Fourth, plastic film bag storage method
The 0.07-0.08 mm thick film polyethylene plastic bag is used to seal the storage of carrots in the raft or in the ventilation warehouse, which can effectively inhibit dehydration and germination, and is stored at a low temperature of 1 ° C, and the effect is very good.
