Abstract
The invention discloses a heat supply and drip irrigation system of a root zone. The heat supply and drip irrigation system of the root zone is characterized by comprising an air compressor, an air storage tank, a pressure adjuster, a heating pipe and a drip irrigation pipeline system, wherein warm air is conveyed to the root zone of a plant by an underground drip irrigation system. Therefore, air and heat environments around the root of the plant can be effectively improved, the adverse effects of low-temperature chilling damage are avoided, and the purposes of improving the utilization efficiency of liquid manure, increasing economic yield and improving harvest quality are fulfilled. According to the system, air can be heated by circulating hot water or in a manner of electrifying to warm; and the pressure adjuster can control the air pressure inside the air storage tank within a certain range, adjusts the additive amount of air by a change of the pressure of the air storage tank, and is matched with the air storage tank with large size at the same time so as to avoid frequent start of the air compressor.
Description
Technical field:
The present invention relates to agricultural irrigation technology, be specifically related to a kind of district's heat supply drip irrigation system.
Background technology:
Soil temperature is subjected to the impact of the factors such as solar radiation, terrestrial space heat balance feature, atmospheric temperature and soil water regime, soil temperature is one of overall target that characterizes the soil heat situation, also is the important indicator of earth surface energy balance and greenhouse effect.Soil temperature is the key factor that affects crop growth and change of soil fertility, has reflected soil-vegetation-atmosphere system energy flow and mass exchange.Soil temperature changes the waterpower degree of leading of root system of plant and validity and the kinetic characteristic of the soil water by the impact on root system of plant layer soil water temperature and root zone Pore structure in soil and capacity of water supply, finally affects growing of plant.Root system is the major organs of plant absorbing moisture and nutrient, the physiological function of root system of plant is subjected to the ratio that affects of root region soil temperature to be subjected to overground part temperature effect more responsive, the rhizosphere environment temperature directly affects water uptake by plant roots and the rising dehydration of blade, thereby affects the growth of plant.The chilling injury of root region soil will produce severe jamming to the physiological function of root system of plant, and then the leaf growth of plant, photosynthesis characteristics, dry-matter accumulation, root system produced adverse influence to the absorption of mineral element and soil respiration and soil microbial activity, finally have influence on plant liquid fertilizer utilization ratio and final yield and quality.Comparatively ripe to the external temperature control technique of plant growth environment at present, just can realize this function such as industrialized agricultures such as green houses, relevant regulation and control to plant roots district soil environment temperature are shorter mention then, and this problem also is restriction cold district plant or a key technology difficult problem that winter, the facility plant health was grown up.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and provide a kind of to distinguish the heat supply drip irrigation system, utilize underground drip irrigation system that warm air is transported to the plant roots district, can effectively improve the plant rhizosphere environment, mainly solve the root region soil low temperature stress to the disadvantageous problem of root system of plant, reach and improve the plant liquid fertilizer utilization ratio, increase economic flow rate and improve the purpose of quality.
Technical scheme of the present invention is: a kind of district's heat supply drip irrigation system, and its special character is to be comprised of air compressor, air accumulator, delivery main, bypass line and underground drip irrigation hollow billet; Described air accumulator is with heating tube and pressure regulator, and heating tube is fixed in the air accumulator; Described air compressor and air accumulator are connected through the first connecting pipe, and air accumulator is connected by the second connecting pipe and the delivery main with switch; Described delivery main is provided with controlled valve, and controlled valve is positioned at the second connecting pipe and is connected with delivery main before the position; Described delivery main is communicated with bypass line, and bypass line communicates with the underground drip irrigation hollow billet.
Compared with the prior art a kind of district's heat supply drip irrigation system of the present invention have outstanding substantive distinguishing features and marked improvement, and 1, the underground drip irrigation system that added heat utilization in plant roots district, reduced extra investment, lowered the cost of system; 2, heating tube both can heat by the hot water of circulation the air in the air accumulator, can heat by the mode that energising heats again the air in the air accumulator; 3, pressure regulator can be controlled at the gas pressure in the air accumulator certain scope, cooperates the air accumulator of larger volume, has avoided the frequent starting of air compressor.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Embodiment:
For Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the present invention in detail.
Embodiment 1, referring to Fig. 1, select suitable air compressor 1 and air accumulator 2 according to the design needs, the two is connected by the first connecting pipe 9, air accumulator 2 is made by stainless steel or other hard metal materials, and the pressure that bears is guaranteed safety for when normal operation 2 times of set upper pressure limit, and the volume of air accumulator 2 is enough large, prevents from acutely causing air compressor 1 frequent starting because of gas pressure change in it; Heating tube 3 is positioned at air accumulator 2 and the position is fixed, can not move or wave with air-flow or other external force, heating tube 3 both can heat by the hot water of inner loop the air in the air accumulator 2, can heat by the mode that energising heats again the air in the air accumulator 2; Setting pressure adjuster 4 on air accumulator 2, pressure regulator 4 can be controlled at certain scope with the gas pressure in the air accumulator 2, air compressor 1 quits work when the gas pressure in the air accumulator 2 reaches the upper limit, and air compressor 1 is started working when the gas pressure in the air accumulator 2 reaches lower limit; Air accumulator 2 is connected by the second connecting pipe 11 and delivery main 7 with switch 5, controlled valve 6 is installed on the delivery main 7, and controlled valve 6 is positioned at the second connecting pipe 9 and is connected with delivery main 7 before the position; Delivery main 7 is connected with bypass line 10, again bypass line 10 is connected with underground drip irrigation hollow billet 8, form a kind of district's heat supply drip irrigation system of the present invention.
A kind of district's heat supply drip irrigation system of the present invention, when being the heat supply of root district, controlled valve 6 is in closed condition, and switch 5 is in open mode, and compressor 1, heating tube 3 and pressure regulator 4 all are in normal operating conditions; When being root district supplying drip irrigation, delivery main 7 normal water supplies, controlled valve 5 is in closed condition, and switch 6 is in open mode, and compressor 1, heating tube 3 and pressure regulator 4 all are in the state of quitting work.
