Embodiment 1

[0051] Embodiment 1: seefigure 1 , this high-temperature hot water soil sterilization method uses a hot water soil sterilization machine to heat the water to 90°C, distributes the hot water to the hot water branch pipe 3 through the hot water main pipe 2 and the distribution pipe 8, and then the hot water branch pipe 3 The spray hole 9 sprays out, and directly infiltrates the soil surface to the depth of 20Cm, and the temperature after the hot water is injected into the soil is 60°C, and the soil surface is covered with a plastic insulation film to keep it warm for 0.5 hours. The steps are:

[0052] (1), before the soil is disinfected, the soil is loosened, and the depth of the soil for planting leafy vegetables is 20cm;

[0053] (2) Lay hot water spraying pipes at intervals on the soil to be sterilized, and the hot water spraying pipes are densely covered with water spraying holes;

[0054] (3) Cover the soil and the hot water spray pipe with thermal insulation film;

[005...

Embodiment 2

[0058] This high-temperature hot water soil sterilization method uses a hot water soil sterilization machine to heat the water to 95°C, spray it through the water nozzle on the hot water spray pipe, and directly penetrate into the soil surface to a depth of 30cm. After the hot water is injected into the soil The temperature of the soil is 85°C, and the soil surface is covered with a plastic insulation film to keep it warm for 1.0 hour. It is characterized by the following steps:

[0059] (1) Before the soil is sterilized, the soil is loosened, and the depth of the soil for fruit and vegetable planting is 30cm;

[0060] (2) Lay hot water spraying pipes at intervals on the soil to be sterilized, and the hot water spraying pipes are densely covered with water spraying holes;

[0061] (3) Cover the soil and hot water spray pipe with plastic insulation film;

[0062] (4) Use a high-temperature hot water soil disinfection machine to heat the water to 95°C, open the hot water valve...

Abstract

The present invention is high temperature water soil sterilizing method and high temperature water soil sterilizing machine. After the soil to be sterilized is loosened, hot water spraying pipes with dense water spraying holes are spread, heat insulating film is covered onto the soil and the pipes, and hot water heated to 37-95 deg.c in the high temperature water soil sterilizing machine is sprayed to soil and maintained for 0.5-5.0 hr to sterilize soil. The said method can kill pests and germs while retaining great amount of saprophytic rhizobia in soil, has no harm to crops and no environmental pollution and is favorable to production of green agricultural product.

Description

(1) Technical field [0001] The invention relates to a soil disinfection method and equipment used therein. (two), background technology [0002] In recent years, the area of ​​crops with important economic value such as melons, fruits, vegetables, and flowers has expanded rapidly, and the production area of ​​protected areas has continued to increase. High-density cultivation of facility agriculture and planting of the same crop on the same piece of land year after year will all lead to soil-borne diseases. Accumulation, growth and reproduction of pathogenic bacteria. If this kind of disease is not controlled in time, it will cause serious reduction in production or reduce product quality, or even result in failure of harvest. Soil disinfection is one of the important measures to control soil-borne diseases, and has gradually been accepted by farmers. [0003] Soil disinfection methods commonly used at present include medicament disinfection, solar disinfection and steam h...
