Description

Soil disinfection method using electric heating element and bran}

The present invention relates to a soil disinfection method using an electric heating element and bran in a facility house.

Soil infectious pests survive long in the soil, causing many edible and horticultural crops and reducing yields. Soil pest control methods such as methyl bromide and chloropicrine before and after crop cultivation are used as methods for controlling soil infectious pests. However, it is recognized as a cause of environmental pollution and toxic substances. In addition, the natural cycle of organic farming and agricultural environment is emphasized, and the chemical soil fumigation method has reached a limit to being settled in a practical way despite the excellent control effect. In general, it is known that soil fumigation method has the potential to destroy pathogens and useful microorganisms, destroy the biological balance of the soil, and cause the soil to create microbial vacuum and cause more damage than the pests that were controlled. have. Therefore, farmers are actively seeking new soil disinfection methods that solve the difficulties and costs of using chemical pesticides and ensure safety.

In organic farming, pest control of soil infectious pests is relatively difficult to establish, rather than pests occurring on the ground, because effective surveillance systems are not established. The use of physical energy from solar heat as a method of soil sterilization that preserves the diversity of the agricultural environment and minimizes external input has proven to be one of the eco-friendly agricultural technologies.

Conventional southern semi-high cold regions and Gangwon regions are major production areas of summer vegetable vegetables such as tomatoes, and the duration of the growing season increases the area of crop disturbances such as the occurrence of diseases, but soil sterilization is essential for reducing the damage of crops. Soil disinfection using is difficult to apply in high temperatures. There is a need to develop soil disinfection methods suitable for the areas where the high temperature, which is a major production site for summer vegetables, is used to alleviate the damage of high-altitude land and to disinfect soil during the cold season.

During the solar heat disinfection in July ~ August, the change of soil temperature during the day reached the highest temperature of 60 ℃ from the depth of 10cm between 16 ~ 18 hours and the lowest temperature around 7am (excluding the rainy season).

However, in the 20cm and 30cm depths, the temperature difference was more than 10 ℃, but the temperature distribution was around 40 ℃, indicating that the effect of solar disinfection was around 10cm.

Since crops absorb nutrients necessary for growth near 10 to 20 cm of soil and soil infectious plant pathogens are active in similar areas, it is considered that the transfer of solar temperature near the surface will contribute to reducing the activity of pathogens.

Facility House The semi-high-cooled area is a major producer of summer vegetable vegetables such as tomatoes because of its cool and strong sunlight. However, with the prolonged period, the area and extent of serial damage, such as disease occurrence, are gradually increasing. In Unbong, Namwon-si, Jeollabuk-do, about 30% of the plants died during the hot season of June ~ July in 2008, and 20-40% of the plants died during the low temperature of February ~ March 2009. Occurred.

It is a semi-cooled area of 400 ~ 500m above sea level. Even in mid-April, the soil temperature in rain forest house is only 12.5 ~ 19.8 ℃. Therefore, it is a problem that the present invention is difficult to apply because it is not possible to increase the inside of the soil to about 40 ° C. in the low temperature state, such as solar heat + bran treatment using the hot weather in summer.

The present invention is to solve the above problems, consisting of an electric heating element and an automatic control device having an exothermic temperature of 105 ℃ on the basis of a 100m long, 6.5m (600㎡) wide area of the facility house, a semi-cold paper that has to be soil sterilized at low temperature It is a problem solving means of the present invention to provide a soil disinfection method using an electric heating element and bran to treat the soil with a bran and an electric heating element to be suitable for the reverse.

In the present invention, the soil is generally sterilized at 40 ° C. or higher, and since the bran is fermented at about 40 ° C., the fermentation of bran is used as a disinfection sensor of the soil, and when the bran is fermented, the soil is heated to an exothermic temperature during fermentation. The temperature rises or raises the exothermic effect of the electric heating element, and after fermentation automatically composting effect,

It is economical and economically effective in maximizing the technical effect in the extreme areas of soil disease and crop damage, increasing farm household income, reducing crop damage and preserving soil health by maximizing stable production of plant vegetables.

In order to achieve the above object, the present invention is composed of an electric heating element and an automatic control device having an exothermic temperature of 105 ° C based on a 100m long and 6.5m (600㎡) wide area of the facility house, and the soil sterilization treatment must be performed at a low temperature. The present invention relates to an electric heating element and a soil disinfection method using an electric heating element and a bran which are additionally treated by treating the existing wheat bran to be suitable for a sub-cooling area.

Bran is mixed with soil and bran in 1 ~ 2ton / 10a (a = 100㎡) considering soil inorganic nitrogen content.

Soil is generally sterilized above 40 ℃, and bran fermentation begins around 40 ℃, so fermentation of bran can be considered as soil is being disinfected.

The fermentation of bran can be seen as a sensor for soil disinfection.

When the bran fermentation starts, the soil temperature rises to the exothermic temperature during fermentation or the exothermic effect of the electric heating element is raised, and after fermentation, it is automatically composted. Of course, other plants do that too,

In the present invention, it was developed to contribute to farm income by using wheat bran, which can be obtained cheaply and easily around.

The present invention installs a heating wire of the electric heating element after the bone in the soil 20cm deep. Mulch enough water to keep the soil moisture above the maximum water and mulch it with vinyl to minimize the flow of air. Turn on the electric heating element and heat the electric heating element at 105 ℃ to disinfect the soil for 20-30 days, then turn off the power. Remove the vinyl, degas it sufficiently, remove the heating element, and get ready.

Hereinafter, the present invention will be described in detail with reference to examples.

Fertilize the bran with 1 ~ 2ton / 10a (a = 100㎡) in the soil in the facility house, mix it with a depth of 20cm in the soil, install a heating wire of the electric heating element, and then check the maximum amount of soil water. After watering enough to be ideal, and mulching with vinyl to minimize the flow of air. The electric heating element was turned on and the heating element was heated to 105 ° C. to disinfect the soil for 20 to 30 days. Then, the power was turned off, the vinyl was removed, the gas was sufficiently removed, and the electric heating element was removed to disinfect the soil.

Since then, it is a way to grow the desired crop in the facility house.

It consists of an electric heating element with an exothermic temperature of 105 ℃ and an automatic control device based on a 100m length and a width of 6.5m (600㎡). It is applied to the existing bran treatment method to be suitable for sub-high-cooled areas where soil sterilization should be performed at low temperature.
