溶液培养实施过程中,由于植物的蒸腾作用,培养罐内营养液不断减少,通常需要培养者每天或定期用营养液或水补回至原有体积,费时费工。这里介绍一种结构简单、操作方便、造价低廉的液培自动补液装置。小规模液培中使用此装置,可在数天内自动保持培养罐内溶液体积恒定。该装置称“Mariotte’s
During the process of solution culture, due to the transpiration of plants, the nutrient solution in the culture tank is constantly decreasing, and it is usually time-consuming and labor-intensive to replenish the original volume with nutrient solution or water daily or regularly. Here introduced a simple structure, easy operation, low cost liquid culture automatic rehydration device. This device is used in small-scale hydroponics to keep the volume of the solution in the culture tank constant for several days. The device is called "Mariotte’s
