Seedling identification system and method of soil-hardening salination soil seed bank

Abstract

The invention discloses a seedling identification system and method of a soil-hardening salination soil seed bank, and belongs to the technical field of identification of the soil seed bank. The identification system comprises a time control module, a temperature control module, a central control module, an immersion module, a rinsing module, a seedling culturing module and a species quantity identification module. The problem that severe soil hardening influences germination of seedlings in the prior art is solved via the immersion module, the rinsing module and the seedling culturing module,and a more accurate identification method is provided for research on the soil-hardening salination soil seed bank; the species quantity identification module plants screened seeds in the appropriatesoil environment directly; and the types and quantity of species separated by the method are both exceed those of a traditional manual sorting method respectively, and it is shown that the precisionand efficiency are both higher than those of the traditional method respectively.

Description

technical field [0001] The invention belongs to the technical field of soil seed bank identification, and in particular relates to an identification system and identification method for hardened and salinized soil seed bank seedlings. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Soil seed bank refers to the sum of all active seeds existing in soil surface litter and soil. Viable seeds in the soil are part of the plant community and are the source of new plants. Soil seed banks can be divided into transient soil seed banks and persistent soil seed banks. With the development of community ecology, the study of soil seed bank has become an important part of plant ecology. The research contents mainly include: the composition and distribution of soil seed bank; the dynamics of soil seed bank; the relationship between aboveground vegetation and soil seed bank; The role of disturbance on soil seed ba...

AI Technical Summary

Problems solved by technology

[0007] The high salinity of the existing soil causes the high osmotic potential of the soil solution, which leads to the problem that the seeds cannot germinate, and thus cannot be accurately identified;

[0008] At the same time, directly identify the species and quantity of the heavily salinized soil seeds, and separate the species through the traditional hand-picking method, and the identification data is inaccurate

[0009] In the temperature control in the prior art, there is no PID adaptive temperature control method based on the particle swarm optimization strategy, and there is no real-time temperature control method suitable for nonlinear inertial system applications.

Moreover, in the prior art, because the PID control method is prone to overshoot, and does not have the ability to adjust parameters online, the self-adaptive ability is poor

[0010] In the operation control of existing equipment, the digital PID control technology is relatively mature, the structure is relatively flexible, and the control effect is relatively ideal, but it needs to control the three parameters (K p , K d , K i ) for pre-setting, considering that the regulation itself changes very slowly, which is not conducive to the adjustment of operating parameters and system debugging
