Abstract

The utility model provides a hot-water heating formula big-arch shelter dish improves ground temperature new technology, includes solar energy or boiler (1), raceway (2), wet return (3), circulating pump (4), its characterized in that: the hot water conveying pipes are all installed by aluminum alloy or plastic pipelines and are arranged at equal intervals, the circulating pump (4) pumps hot water out of the solar energy or the boiler, the hot water is compressed to a main pipeline and then is uniformly conveyed to underground pipelines, heat is transferred to the ground, and cold water is returned to the boiler or the solar energy. The circulation is carried out in such a way, and the ground temperature is improved. The novel water heating technology for improving the ground temperature of greenhouse vegetables thoroughly changes the traditional mode, is a leap of a greenhouse production technology, is synchronous in greenhouse temperature and ground temperature, is heated up and down simultaneously, overcomes the fatal defects of out-of-season vegetable production caused by high greenhouse temperature and low ground temperature in winter cultivation of greenhouse vegetables, is developed in root systems of greenhouse vegetables, high in yield, early in marketing, less in diseases and high in benefit, and meets the requirements of vegetable baskets of people in cities and countryside.

Description

Water heating type high-yield technology for increasing ground temperature of greenhouse vegetables

Technical Field

The invention relates to facility agriculture (greenhouse-vegetable basket engineering). In particular to a water heating type new technology for improving the ground temperature and the high yield of greenhouse vegetables.

Background

The existing greenhouse agricultural greenhouse vegetable is cultivated in winter, so that the ground temperature is low, the vegetable grows slowly, the diseases are more, the yield is low, and the income is less. The high technique is continued to be dry, and the low technique is closed again. The dish price is high. Especially in northern areas.

Disclosure of Invention

The invention mainly solves the defects of the prior art. Hot water is circulated in the buried pipe to improve the geothermal technology. The greenhouse vegetable can be produced in high yield and can be sold in the market in the morning.

The above technical problems of the present invention are: mainly solved by the following technical scheme. A new water heating technology for improving the ground temperature of greenhouse vegetables. And digging a ditch in the vegetable shed at the depth of 18 centimeters away from the ground. Aluminum alloy or plastic pipelines with the diameter of 4 centimeters are arranged every 10 centimeters and are uniformly arranged. The length of the pipeline is as long as that of the greenhouse field. One end is connected with a solar energy or boiler circulating pump. All ports of the buried pipe at the other end are connected on a header pipe in a gathering way and communicated with a circulating pump. Forming a closed hot water circulation pipe network. The circulating pump is driven by the motor. The solar energy or boiler hot water uniformly conducts heat to the ground through the buried pipeline. And then returning the cold water to the solar energy or the boiler, and circulating for several times every day.

Preferably, the circulating pump is driven by the motor to convey solar energy or boiler hot water to each pipeline underground. The ground temperature is increased, the vegetables grow fast, and the yield is high. The water heating type ground temperature raising method has higher cost than the hot air method, but has good effect.

The water heating type low-temperature technology provided by the invention has the advantages of simple equipment, easiness in installation, one-time investment and long-term use, and actually, the ground heating pipe is installed for the ground, and the same principle as that of a ground heating system of a human-living house is realized. The heating of human housing is skillfully used on the ground. A small boiler can be used for a plurality of greenhouses, the ground temperature is increased, and the vegetable root system is developed. Quick absorption and excellent benefit.

Drawings

FIG. 1 is a schematic view of a hot water cycle of the present invention.

FIG. 2 is a schematic view of the uniformity profile of the underground pipe of the present invention.

1-solar energy or boiler, 2-water main pipeline, 3-underground heat transfer pipeline, 4-circulating pump, 5-return pipe.

Detailed description of the preferred embodiments

The technical solution of the present invention is further illustrated by the following examples in combination with the accompanying drawings: as shown in fig. 1 and 2. The main pipe is led out from the boiler and connected to each buried pipe through an interface. The branch pipes transfer the heat to the ground. Finally, cooling water in pipelines and returning the cooled water to the boiler, and circulating the steps for a plurality of times every day as appropriate. The benefit is improved by more than one time only through the sweet potato seedling test.

The water heating method for improving the ground temperature of the greenhouse vegetables thoroughly changes the traditional mode, is a leap of the greenhouse vegetable production technology, and enables the ground temperature and the room temperature to be synchronous and to be heated up and down simultaneously. Overcomes the fatal weakness of the out-of-season vegetable production technology of high greenhouse temperature and low ground temperature. The root system of greenhouse vegetables is developed, the greenhouse vegetables are sold in the market early, the yield is high, the diseases are few, the benefit is high, and the vegetable basket requirements of urban and rural people are met.

The specific embodiments described above. But merely as a preferred illustration of the principles of the invention. Any modification, addition or substitution made of equivalents within the spirit and principles of the present invention. Are intended to be encompassed by the present patent and claims.

Claims

1. A new technology for increasing the ground temperature of water heating type greenhouse vegetables comprises a solar energy or boiler (1), a water delivery pipe (2), an underground heat transfer pipeline (3), a circulating pump (4) and a water return pipe (5). The method is characterized in that: the heating water pipes are all installed by aluminum alloy or plastic pipelines and are arranged at equal intervals. The circulating pump (4) pumps hot water out of the solar energy or the boiler, compresses the hot water into the main pipeline, evenly conveys the hot water to each underground pipeline, transfers heat to the ground, and then sends cold water back to the boiler or the solar energy, so that the circulation improves the ground temperature.

2. The number of times per day, as appropriate.
