A device for hydroponic stress of fir seedlings

Abstract

The invention discloses a hydroponic stress device for germinated fir seedlings, which comprises a hydroponic cylinder, the inner side wall of the upper end of the hydroponic cylinder is provided with an annular slot, and the annular slot is embedded with the bottom surface of the upper end of the seedling cultivation tube in the seedling raising device. The evenly distributed threaded holes on the ring plate at the upper end of the seedling raising tube in the seedling raising device are threadedly connected with the threaded holes on the ring plate at the bottom end of the annular cavity tube in the temperature control device through bolts. Simple, convenient installation and separation, convenient adjustment, which brings great convenience to users, and can monitor the temperature of seed growth, oxygen concentration and pH value information of the growth solution in real time according to the growth needs, so as to facilitate the control of the growth environment , providing a suitable growth stress space for the fir seeds, reducing the workload of personnel, ensuring the seedling quality of the fir seeds, and improving the use efficiency of the hydroponic stress device.

Description

technical field [0001] The invention relates to the technical field of hydroponic stress equipment, in particular to a hydroponic stress device for germinated fir seedlings. Background technique [0002] Chinese fir is an important timber tree species in southern my country. In recent years, with the development of science and technology, related research on Chinese fir has gradually begun at home and abroad. However, due to the relatively long growth cycle of Chinese fir, most of the current basic research is carried out at the seedling stage. , and carrying out relevant hydroponic research on fir seedlings of different sizes requires different hydroponic stress devices, but the traditional hydroponic stress devices have active problems, inconvenient operation, and inconvenient installation and separation, which brings great inconvenience to users. It is a big trouble, and it is impossible to monitor the temperature, oxygen concentration and pH value information of the growth...

[0002] Chinese fir is an important timber tree species in southern my country. In recent years, with the development of science and technology, related research on Chinese fir has gradually begun at home and abroad. However, due to the relatively long growth cycle of Chinese fir, most of the current basic research is carried out at the seedling stage. , and carrying out relevant hydroponic research on fir seedlings of different sizes requires different hydroponic stress devices, but the traditional hydroponic stress devices have active problems, inconvenient operation, and inconvenient installation and separation, which brings great inconvenience to users. It is a big trouble, and it is impossible to monitor the temperature, oxygen concentration and pH value information of the growth liquid in the seed production environment in real time according to the production needs. It is inconvenient to control the growth environment, and it is impossible to provide a suitable growth stress space for the fir seeds, which virtually increases the number of personnel. The work burden cannot guarantee the seedling quality of fir seeds, resulting in low efficiency of the use of hydroponic stress devices. Therefore, the realization of a device for hydroponic stress of fir seed germination seedlings that can solve such problems is imperative
