Background technology
China's facilities horticulture industry is quickly grown in recent years, and is progressively developed to scale, intensive direction, technical merit
Have increased significantly.According to statistics, China's facilities horticulture obtains nearly 20% plantation with the planting industry soil less than 3%
The industry output value, and this data is increasing year by year.
Facilities horticulture belongs to annual plantation, and the environment of high temperature, high humidity is chronically in facility plastic greenhouse, makes some germ worms
Ovum and pest are bred year after year, are largely accumulated in cultivation matrix or soil, and intractability is larger.In addition facilities horticulture
Crop cultivation speciality degree is higher, and the crop species of plantation are relatively fewer, so continuous cropping is prevailing, cause worm's ovum in soil, fungi and
The accumulation year after year of virus, some soil-borne disease insect pests take place frequently, and seriously constrain the development of facility cultivation, general underproduction when disease occurs
20%~40%, when serious the underproduction up to more than 60% even have no harvest.Therefore, it is to change to carry out disinfection to the soil in facilities horticulture
Crop ecological environment in kind garden, improves agriculture value, promotes the important measure of agro based economic development.
Facilities horticulture soil disinfection method is broadly divided into two major class of chemical disinfection and physical disinfection.Chemical disinfection because it is simple,
Quickly, efficiently, it is still main disinfection means, but produces food security and problem of environmental pollution, development to be subject to there are pesticide residue
