Abstract

The invention discloses a solar ground heating vegetable greenhouse, which comprises a vegetable greenhouse, a solar energy collection water tank, solar collector tubes and a heating coil. The heating coil is buried in soil of a greenhouse culture bed arable layer of the vegetable greenhouse, a water inlet of the heating coil is communicated with a hot water outlet of the solar energy collection water tank through a water inlet pipe, a water outlet of the heating coil is communicated with a return water inlet of the solar energy collection water tank through a water return pipe, and a water pump is disposed on the water inlet pipe or the water return pipe. The solar ground heating vegetable greenhouse is reasonable and simple in structure, input cost is lower than that of the solar ground heating vegetable greenhouse in the prior art, heating efficiency is high, the temperature problem restraining growth of fruits and vegetables in winter can be solved without using a stove or other heat sources, and yield of vegetable crops is increased.

Description

A kind of solar earth heating green house of vegetables
Technical field
The present invention relates to the green house of vegetables ground heating system, especially a kind of solar earth heating green house of vegetables.
Background technology
China's most of areas winter severe cold and very long in the Winter-Spring cold season that crops can't grow, is greatly developed booth vegetable production and is the inevitable course.At present, through building all kinds of green houses, solved the vegetables consumption problem of part Winter-Spring cold season; Yet; Along with the continuous growth of the size of population and improving constantly of people's living standard, winter vegetable output still can not satisfy huge demand, and it mainly is because winter climate is cold; Sunlight is not enough, and facilities horticulture production receives very big restriction.Wherein, the problem that soil temperature is lower fails effectively to be solved always.No matter be greenhouse by solar heat, or traditional greenhouse of heating, soil temperature is through improving after the room temperature, improves ground temperature indirectly, so the soil efficient of heating is very low and the soil programming rate is slow.Winter greenhouse, the majority leaf vegetables of also can only growing is produced fruit and vegetable and also must be improved soil temperature and could realize.Room temperature in the booth is through the sunshine heating, utilizes thermal source additional heat such as stove or radiator with heating in the canopy again, though take above measure, also can only make in the greenhouse temperature reach (cloudy day) about 12 ℃ daytime; About 6 ℃ of nights; The soil temperature of 10~20cm thickness generally has only about 9 ℃ in the canopy, under such environmental temperature, only can satisfy the growth needs of some leaf vegetabless in the canopy; Can't reach the temperature requirement that the fruit vegetables normal growth is grown; Winter, temperature of irrigation water generally had only about 4 ℃, and the low excessively problem of the indoor ground temperature in back of therefore watering has become the bottleneck that restriction fruit vegetables in winter is grown.The root system degree of depth of various crops is different with the requirement to temperature and soil temperature, generally between the 11-40 degree.
Summary of the invention
The objective of the invention is to: a kind of solar earth heating green house of vegetables is provided, can utilizes solar energy to heat for soil, rational in infrastructure, simple, heating cost is low, efficient is high.
For realizing above-mentioned purpose, the present invention can take following technical proposals:
A kind of solar earth heating of the present invention green house of vegetables; Comprise green house of vegetables; Also be provided with the solar energy heating water tank; Solar energy heat collection pipe, the greenhouse by solar heat that is embedded in said green house of vegetables is cultivated the heat(ing) coil in the bed topsoil, and the water inlet of said heat(ing) coil is communicated with the hot water outlet of said solar energy heating water tank through water inlet pipe; The delivery port of said heat(ing) coil is communicated with the backwater import of said solar energy heating water tank through return pipe, on the pipeline of said water inlet pipe or return pipe, is provided with water pump.
Said heat(ing) coil is the PEX cross-linking tube.
Said water pump is the temperature control water pump, in said greenhouse by solar heat cultivation bed topsoil, is provided with temperature sensor, and this temperature sensor is electrically connected with said temperature control water pump.
The depth of burying of heat(ing) coil is 45% of a said greenhouse by solar heat cultivation bed topsoil thickness.
Compared with prior art the invention has the beneficial effects as follows: owing to adopt technique scheme; In the greenhouse by solar heat cultivation bed topsoil of green house of vegetables, be embedded with heat(ing) coil by the heat supply of solar energy heating water tank; Low or open water pump evening in temperature; Through the heat cycles pipeline, heat is supplied with said smooth greenhouse culture bed topsoil, for vegetables provide suitable growth temperature.Because the present invention is rational in infrastructure, simple; Use input cost of the present invention lower than prior art; The efficiency of heating surface improves than prior art greatly, need not dispose other thermal source such as stove and just can solve the temperature problem that restricts the fruit vegetables growth winter, improves the output of vegetable crop.
Further beneficial effect is: heat(ing) coil adopts the PEX cross-linking tube, with the certain ground degree of depth and tube pitch of burying, is laid in the greenhouse by solar heat cultivation bed topsoil, and heat with the radiation mode transmission, has further been improved the efficiency of heating surface.Water pump adopts the temperature control water pump, and the adjusting of soil temperature is decided by the rotating speed of water pump, and when temperature was hanged down, rotating speed increased, and strengthened heat supply, and the control soil conservation is temperature required.When the depth of burying of heat(ing) coil be said greenhouse by solar heat cultivation bed topsoil thickness 45% the time, the efficiency of heating surface is the highest, and is the most favourable to the growth of vegetables.Use the optimum technical scheme of the present invention, greenhouse cucumber output can improve more than 30%, and agaricus bisporus on average increases production 3.2 tons/mu, and cherry, the tomato output value on average reach 10,000 yuan/mu.
