“…The continuous change of outdoor environment factors constantly affects the condition of environment in mushroom house. The uncertainty is an unavoidable problem in the control system [31][32][33] . Therefore, the control algorithm must adjust its parameters in real-time according to the situation of mushroom house.…”

“…According to the prior fuzzy decoupling rules, supplement values for the compost moisture control and environment humidity control are obtained by the fuzzy decoupler. Both supplement values were superimposed with output values of their original fuzzy controllers, and the final control quantities were obtained [33,36] . In the process of CO 2 concentration control, the sensor monitors the CO 2 content in mushroom room in real-time and compares it with the preset value.…”

Environment parameters are the main factors affecting the growth and development of Agaricus bisporus. Because of the requirements of environmental conditions for high-efficiency industrialized production of Agaricus bisporus, equipments for environment control were developed. Based on the variable operating equipment, a multi-factor fuzzy controller was designed to realize the comprehensive control of ambient temperature, humidity, CO 2 concentration, and the temperature and moisture of the compost. The test results showed that the temperature control error was less than ±0.5°C and the response speed was more than 0.5°C/h; The control error of ambient humidity was less than ±2% RH, and the response speed was more than 9% RH per hour; The moistures at different points in compost ranged from 50% to 70% with a standard deviation of 4.04. The control accuracy of environmental CO 2 concentration was within 200 µmol/mol. The overall performance of the control system was stable and reliable, which could meet the requirements of environment factors for the growth of Agaricus bisporus. The system can provide technical support and reference for the automatic and precise control of the environment during the industrialized production of Agaricus bisporus.

“…There are two main reasons for missed planting: 1) There are holes and lack of seedlings in the plug seedlings cultivated in the factory, and the subsequent mechanical transplanting process cannot identify and avoid the holes and missed plants [2] ; 2) Poor quality plug seedlings are produced due to diseases and transportation damage, and the occurrence of diseases and dead seedlings after transplantation causes missed planting [3] . At present, the problem of missing planting mainly relies on manual inspection and timely replenishment of seedlings, but this method is easy to damages the growth consistency of transplanted seedlings and causes subsequent mechanized production problems [4][5][6] . Limited by the cost of factory seedlings, the factory seedlings are directly transplanted by transplanter after leaving the factory, and the cavities and diseased seedlings cannot be removed by transplanter.…”

Healthy vegetable seedlings are surviving seedlings with good biological characteristics. Selective planting of healthy seedlings in the mechanized transplanting process can effectively avoid the reduction in yield caused by missed planting. Aiming at the current transplanting machinery that cannot achieve the selective planting of healthy seedlings, a healthy seedling intelligent sorting and transplanting system was proposed. The system consisted of a seedling delivery mechanism, sorting mechanism, photoelectric sensor, image sensor, PLC control system, and computer control system. It can realize automatic transmission of seedling trays, automatically identify the information of healthy seedlings in the trays and selectively transplant them. Also it can reduce the missed planting rate caused by the poor quality of plug seedlings after planting and the lack of seedlings in the hole. A sorting test of plug seedlings was carried out for the age-appropriate pepper plug seedlings cultivated in the factory. The results showed that the system had an average recognition accuracy rate of 89.14% and an average sorting success rate of 93.20% in the process of sorting suitable age pepper plug seedlings. The whole system can identify, sort and transplant the plug seedlings of appropriate age according to healthy information, and effectively avoid missing planting. This research can provide technical support for the intelligent upgrade of transplanting equipment.

“…According to the type of planter, it can be divided into clamp type, flexible disc type, hanging cup type, guide seed tube type, double conveyor belt type, slide branching wheel type and duckbill type. Therefore, it is necessary to optimize the design parameters and key components of vegetable transplanters on the basis of research on vegetable seedling conditions and transplanting effects [11][12][13][14][15] .…”

In order to improve the efficiency and quality of transplanting vegetables in dry land, based on the seedling technology, transplanting effect and analysis of the planting process, a potted vegetable seedlings transplanting machine was designed. It mainly comprised rotary disc type feeding mechanism, five-bar duckbill type planting mechanism (simulated duckbill mechanism, disc cam, connecting rod, crank, fork, cable) and power transmission system. Based on the physical parameters of the seedlings and design requirements, it was determined that the diameter of the duckbill was D=90 mm, the opening and closing angle was 25°, and the taper angle was 17°. A test bench with adjustable parameters was built by analyzing the structure of the planting mechanism and the motion of the working process. The digital speckle technique was used to optimize the parameters, so that the length of the crankshaft Ι was S 1 =100 mm, the length of the crankshaft ΙΙ was S 2 = 80 mm, the length of the connecting rod Ι was S 3 =140 mm, the length of the connecting rod ΙΙ was S 4 =260 mm, the length of rod to connecting the rack was S 6 =314 mm, and the height of planting track was H=450 mm. According to the above parameters and the control requirements of the duckbill mechanism, the cam stroke was determined to be S=15 mm. And the initial phase difference between the two cams was 180°. The experiment was carried out with pepper seedlings as transplanting objects. The results showed that when the planting frequency was 50-70 plants/min, the seedling upright rate was 93%-91.1%, the planting depth qualified rate was 96%-92%. The leakage rate was 0-0.26%, the variation coefficient of plant spacing was 0.37%-0.67%, the injury rate was 0%, and the mechanical damage degree of the mining surface was 2.43-3.77 mm/m 2. The machine can effectively improve the quality of transplanting, which can meet the production needs and design requirements of the mechanism.
