Soil disinfestation with steam has potential to partially replace fumigants such as methyl bromide, chloropicrin, and 1,3-dichloropropene because it is effective, safer apply, less negative impact on the environment. Here, we compared efficacy of + mustard seed meal (MSM) chloropicrin soil disinfection, plant growth, fruit yield in a strawberry ( Fragaria × ananassa ) fruiting field. The MSM wa...

At present, the cascade PID control is widely used to control the superheating temperature (main steam temperature). As Main Steam Temperature has the characteristics of large inertia, large time-delay and time varying, etc., conventional PID control strategy cannot achieve good control performance. In order to overcome the bad performance and deficiencies of main steam temperature control syst...
