Abstract
The invention relates to a method for improving the soil temperature of green house. Wherein. It embeds heat tube in soil, to connect the heat source as heat circulator; the heat medium of heat tube is hot liquid or hot air. The invention can make the soil temperature and air temperature more uniform; and it improves the safety by using hot liquid or air as heat medium. It can adjust the temperature by hand or computer based on different plant kinds.
Description
Technical field
The present invention relates to agriculture field, in particular, relate to a kind of method that is used to improve temperature of green house soil.
Background technology
At present, people adopt green house creation artificial environment to plant various crops has become now a plant husbandry major reform increasing farmers' income, improve living standards of urban and rural residents structure.It relate to various plants such as vegetables, flowers, fruit plantation, grow seedlings and breeding.Its economic benefit and social benefit are appreciable.In the winter of northern area, or the area of plantation mistake season crop, planting environment temperature and soil temperature can not reach the optimal temperature of plant growth, and northern area then causes the universal phenomenon that crop growth period is long, yield poorly.
The green house that present people generally adopt, be to utilize solar radiation to improve the interior room temperature of green house passively, but because the restriction of natural meteorological condition, the degree that temperature raises is unsatisfactory, especially Da Ye class crop base of leaf has seriously influenced the rising of soil temperature to the effect of blocking of sunlight.Therefore, people's way of having taked to install stove, wall with flues in the greenhouse improves the air themperature in the greenhouse.But the quantity of stove and position are very big to the influence of greenhouse temperature, and the temperature in the greenhouse is very inhomogeneous.The flue gas that stove produces not only can cause the pollution to plant, and from the near plant of stove also can cause be heated withered.Thus, the temperature problem in the greenhouse fundamentally is not resolved.Also have to adopt the example that heat sink apparatus improves the booth room temperature is installed.Though this method is installed stove the booth room temperature is improved to some extent, soil temperature does not still improve.It is found that in practice, desire to make plant to grow, guarantee that greenhouse temperature is not unique necessary condition, in addition also must guarantee suitable soil temperature in cold season.Even guaranteed that the room temperature in the soil temperature booth is low, also can guarantee plant growth, simultaneously the booth room temperature is improved, and makes the air themperature field in the booth more reasonable.
In order to improve soil temperature, abroad adopt and in soil, bury heating wire underground, realize the purpose that soil heats up by electrical heating.Though this method has realized soil intensification purpose, heating wire bury the farming that can hinder crop underground, expend a large amount of electric energy and be prone to the short circuit of heating wire, the incompatibility large tracts of land is used.
Therefore, improving the planting environment temperature, especially improve soil temperature, make it adapt to the growth requirement of crop, is the matter of utmost importance that plant husbandry will solve.
Summary of the invention
The present invention is in order to overcome weak point of the prior art, provides a kind of soil and air themperature of making in the greenhouse even, the method for safe in utilization, energy-conservation raising temperature of green house soil.
The present invention is achieved through the following technical solutions:
A kind of method that improves temperature of green house soil is characterized in that, buries heat supply pipeline in greenhouse soil underground, and described heat supply pipeline and thermal source connect to form heat circulating system, for soil provides heat energy.
Heat supply pipeline is positioned at 10-20cm under the root system of the plant of planting.
Described thermal source is central heating or underground heat or industrial exhaust heat or solar energy, and the heating agent in the heat supply pipeline is hot liquid or hot-air.
The present invention has following technique effect:
1. method of the present invention is by burying the temperature that heat supply pipeline improves soil underground in greenhouse soil, make it adapt to the growth requirement of crop, the soil of artificial environment in the plastic greenhouse and the intensification problem of air themperature have been solved, make in the greenhouse soil temperature and air themperature more even, and, adopt hot liquid or hot-air to use safer as heating agent.
2. be connected with thermal source owing to heat supply pipeline, can be according to variety classes or the kind of crop, employing method artificial or computer intelligence control heat medium temperature is adjusted soil and the air themperature in the greenhouse, and the growth needs of adaptation crop uses more convenient.
3. because soil itself has heat storage capacity, can save heat energy, reach purpose of energy saving.
4. thermal source can adopt multiple thermal source, helps the scientific utilization energy.
5. the method for burying heating wire underground need expend a large amount of electric energy, is prone to the aging of electrothermic wire insulation material and the short circuit accident that causes, and the incompatibility large tracts of land is used.

Fig. 1 improves the schematic diagram of the method for temperature of green house soil for the present invention;
Among the figure: 1. greenhouse 2. soil 3. heat supply pipelines.
Embodiment
Below in conjunction with the drawings and specific embodiments to the detailed description of the invention.
Fig. 1 buries heat supply pipeline underground for the present invention improves the schematic diagram of temperature of green house soil method in greenhouse soil, described heat supply pipeline and thermal source connect to form heat circulating system, for soil provides heat energy.Described thermal source can be central heating or underground heat or industrial exhaust heat or solar energy, and the heating agent in the heat supply pipeline is hot liquid or hot-air.
The depth of burying of heat supply pipeline can be different and different according to the kind of planting plant in the greenhouse.Heat supply pipeline generally is positioned at 10-20cm under the root system of the plant of planting, and depth capacity is good less than 40cm.Like this, can either heat up, help energy-conservationly again, can prevent that simultaneously the too high baking to root of the crop of pipe temperature from scalding for soil.
Adopt this technology that the plastic shed soil temperature is improved and guarantee, and improved air themperature indirectly, make air themperature and temperature field more even.The smoke pollution of having avoided the stove heating and having produced and the defective of high-temperature baking.Adopt simultaneously the temperature-rising method of radiator energy-conservation about 2/3, the method safety and reliability than bury heating wire underground in soil prevents the generation of electric shock accidents.
Past, the plant growth cycle prolonged relatively because chamber environment temperature is lower.After taking greenhouse artificial environment control technology, shortened in the crop-planting cycle relatively, output increases.And can adjust the crop-planting kind according to the needs of market economy.When a certain villages and small towns or the crop greenhouse built, zone are concentrated, can adopt central heating, underground heat, industrial exhaust heat, solar energy or other available thermals source, realize the management of central heating in flakes, plant by individual species and to develop into industrialized cultivation, make the proportion of crop planting industry become artificial by the physioclimate influence even Computerized intelligent control.
Although relate to a kind of method that improves temperature of green house soil and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from the spirit and scope of the present invention, all variations and modification are all within the scope of the present invention.
