Solar steam apparatus for killing soil pests in garden

Abstract

The solar steam apparatus for killing soil pests in garden includes at least one sunlight reflecting board capable of swinging in the frame, one water-to-steam converting pipe on each sunlight reflecting board and with one end connected to the water inlet pipe and the other end to the steam conveying pipeline, one netted or grille steam exhausting pipe with several steam outlets, one temperature controlling device connected to the steam conveying pipeline, one pressure regulating valve, one steam pump, and flow rate pump connected serially to the water inlet pipe. The solar steam apparatus can kill germs, pests and other harmful organisms in soil, and has simple operation, low application cost and no environmental pollution.

Description

technical field [0001] The invention relates to a device for killing pests by physical methods, in particular to a device for killing soil-borne diseases and insects in facility gardening by using solar steam. Background technique [0002] The development of protected horticulture provides a good breeding and overwintering place for many diseases and insect pests. Various soil-borne diseases such as blight, verticillium wilt, sclerotinia, root-knot nematode and other soil-borne diseases are becoming more and more prominent, and the losses are getting heavier, and even lead to crop failure. Seriously affect the normal production of protected horticulture in my country. With the extension of planting years, there will be more and more diseases and insect pests, and soil-borne diseases will limit the development of protected horticultural production. Minimize the number of pests and diseases before production, and control the initial source of pests and diseases is the most effe...

[0002] The development of protected horticulture provides a good breeding and overwintering place for many diseases and insect pests. Various soil-borne diseases such as blight, verticillium wilt, sclerotinia, root-knot nematode and other soil-borne diseases are becoming more and more prominent, and the losses are getting heavier, and even lead to crop failure. Seriously affect the normal production of protected horticulture in our country. With the extension of planting years, there will be more and more diseases and insect pests, and soil-borne diseases will limit the development of protected horticultural production.

Minimize the number of pests and diseases before production, and control the initial source of pests and diseases is the most effective way to control the damage caused by pests and diseases. For soil-borne diseases and insect pests with serious losses, the method of soil treatment with pesticides is often used. Single, large dosage, unsatisfactory effect, and short duration of effect. In order to improve the control effect, excessive use of pesticides in many places increases production costs and causes soil pollution

Although methyl bromide fumigation soil disinfection technology is effective and simple, it has been completely restricted due to its damaging effect on the atmospheric environment.

The effect of using lime and straw to treat soil under sunlight and high temperature is also obvious, but limited by the source of lime and straw, if the proportion of lime and straw is not appropriate, the soil pH value may be affected

Hot water or hot steam commonly used abroad for soil disinfection treatment often uses fuel oil for heating, and the application cost is very high, which is not conducive to large-scale application
