description | The sampling equipment comprises a base, an incubator is arranged on the upper side wall of the base, supporting plates located on the outer side of the incubator are symmetrically and fixedly connected to the upper side wall of the base, and a mounting plate is jointly and fixedly connected to the top ends of the two supporting plates; a collecting box is fixedly mounted on the lower side wall of the mounting plate, a guide pipe is fixedly inserted into the left side wall of the collecting box, and an air bag is connected to the left end of the guide pipe. According to the tomato nutrient solution sampling device, the collection pipe moves downwards or upwards, so that adjustment of the collection pipe at different depths in the culture box is completed, tomato nutrient solutions at different depths are sampled, the data accuracy is further improved, a pressing plate moves in the opposite direction, the pressing plate extrudes an air bag, air in the collection box is exhausted, and the sampling efficiency is |
