strawberries are easy to exceed the standard of pesticide residues? At this time of the year, there are more and more similar questions. In fact,
in fact, strawberry itself is a kind of plant with fast fruit bearing, short cycle and less diseases and insect pests. In addition, the strawberry seedlings after regeneration have strong adaptability and less insect pests, so they do not need to be treated with pesticides. In addition, the greenhouse cultivation environment is relatively clean, the general ground will spread a layer of plastic film, even if there are insects in the soil, also can not climb on the strawberry. Therefore, there is no need to worry about it.
strawberries are difficult to clean, because their appearance is rough, and the skin is very thin. They can be washed with tap water first, and then soaked in light salt water for 5 minutes, so that the strawberries are cleaner after washing. Do not remove the strawberries before washing, because if the strawberries are soaked in water, harmful substances will enter the fruit with water, causing more serious pollution. In addition, do not soak strawberries with detergent such as detergent. These substances are difficult to clean and easy to remain in the fruit, causing secondary pollution. The delicate strawberries of
are easy to rot and not easy to preserve when touching water. Strawberries are best washed before eating. If the strawberries are not eaten immediately, the correct storage method is to spread a layer of paper towel or toilet paper on the plate, put the strawberries, seal them with plastic film or sealed bag, and put them into the refrigerator (the best storage temperature of strawberries is 0 ℃ ~ 10 ℃). As long as it doesn’t touch water and sealed well, it can be put for 3 ~ 4 days. If the quality of strawberry is good, it can be put for about 5 days. If you want to keep it longer, it is recommended to put it into the refrigerator freezer and make it into frozen strawberries. The above content of
