One planting fruit-trees height hangs micro-sprinkler irrigation system lower to tree
Technical field
The invention belongs to technical field of fruit tree production, be specifically related to a planting fruit-trees height and hang micro-sprinkler irrigation system lower to tree.
Background technology
Current orchard irrigation mode is mainly based on broad irrigation, extensive with water, and irrigating water quota is high, not only wastes water resource, also destroys orchard vegetation, cause soil erosion. In addition Water Goods consciousness is not strong, there is no and realizes management through quantification, the nervous aggravation of contradictions with water waste of supplying water, it is impossible to meet the requirement of high-efficiency water-saving agricultural development, resist Serious Drought Event ability. Water saving irrigation facility can adopt less irrigating water quota, strict controls orchard soil moisture, so as to need water more to adapt with fruit tree growth, adopts this facility speed of not only irrigating the fields fast, and in good time, irrigate in right amount, can solve fruit tree supply and demand water contradiction.
Summary of the invention
Present invention is generally directed to that orchard irrigation water resource waste is serious, the problem of function singleness, it is provided that a planting fruit-trees height hangs micro-sprinkler irrigation system lower to tree.
Fruit tree height of the present invention hangs micro-sprinkler irrigation system lower to tree, including water source, wherein also include check-valves, gear butterfly valve, sandrock filter, automatic backwashing lamination filter, electronic flowmeter, gate valve, support, upper field arm, shower nozzle and lower field arm, the water inlet of described sandrock filter is connected with water source by inlet channel, on inlet channel, the side near water source is provided with check-valves, on inlet channel, the side near sandrock filter is provided with gear butterfly valve, the outlet of sandrock filter is connected with the water inlet of automatic backwashing lamination filter by outlet conduit, the outlet of automatic backwashing lamination filter is connected with upper field arm and lower field arm respectively by aqueduct, aqueduct is provided with electronic flowmeter, the water outlet direction being positioned at electronic flowmeter on aqueduct is provided with gate valve, upper field arm and lower field arm are arranged on around fruit tree by support, upper field arm is arranged on 50 centimeters above fruit tree, lower field arm is arranged on distance ground 80, the lower section centimeters of fruit tree, upper field arm and lower field arm are designed with shower nozzle.
Further, present invention additionally comprises agrochemical fertilizer tank, described agrochemical fertilizer tank is connected on outlet conduit by batch mixing pipeline.
The sprinkling diameter of shower nozzle of the present invention is 4 meters.
The present invention adopts technique scheme, have the advantages that 1, in northern China, due to the stronger cold current that the annual 3-4 month occurs, the fruit tree such as Fructus Pruni, Lee, Fructus Pruni pseudocerasi earlier that blooms very easily suffers the harm of " cold spell in later spring ", easily freeze bud, freeze colored phenomenon, directly affect the pollination rate of blooming of fruit tree, cause the fruit tree underproduction even to have no harvest, cause great loss to orchard worker. Owing to this facility height hangs micro-spray cans spray site height, whole fruit tree can be covered, in conjunction with weather forecast when frost arrives, facility is utilized to adopt the sucrose water of whole orchard spray 0.5% or 15000 times of sprays green to protect, cold releasing latent heat is met by water, orchard Partial little climate can be effectively improved, improve temperature, play the effect of pre-antifreeze flower. 2, around top fruit sprayer, the infiltration ditch of wide 20CM, deep 15CM is dug, it is possible to avoiding the surface runoff loss produced when spraying, thus improving the utilization ratio of water, saving irrigation water. 3, spray affected by wind bigger, when wind speed is more than 5.5��7.9m/s and moderate breeze, water droplet can be dispelled, add the drift losses of flood, when wind is big, adopt the shower nozzle water spray setting lower field arm, it is possible to decrease water spray height, the water droplet of ejection is affected by wind less, reduces the loss of water. 4, at the dusk of fruit color phase full garden water spray, orchard microclimate condition can be changed, increase day and night temperature, create night dew, promote fruit color. 5, utilizing height to hang micro-spray facility also can carry out spraying foliage fertilizer, spraying insecticide, both savings of labor, laborsaving, effect is notable again. 6, this equipment of sprinkler irrigation is equipped with electronic flowmeter, can according to the irrigation quantity of electronic flowmeter record, and reasonable adjusting is poured water flow, carries out quota management. 7, having sandrock filter, automatic back-washing combined filter twice filtration system on this system pipeline, blockage resisting ability significantly improves, and solves mini sprinkler and holds susceptible to plugging problem.

Detailed description of the invention
Embodiment 1
As shown in Figure 1, one planting fruit-trees height hangs micro-sprinkler irrigation system lower to tree, including water source 1, wherein also include check-valves 2, gear butterfly valve 3, sandrock filter 4, agrochemical fertilizer tank 5, automatic backwashing lamination filter 6, electronic flowmeter 7, gate valve 8, support 9, upper field arm 10, spray shower nozzle 11 and lower field arm 12 that diameter is 4 meters, the water inlet of described sandrock filter 4 is connected with water source 1 by inlet channel 14, on inlet channel 14, the side near water source 1 is provided with check-valves 2, on inlet channel 14, the side near sandrock filter 4 is provided with gear butterfly valve 3, agrochemical fertilizer tank 5 is connected on outlet conduit 15 by batch mixing pipeline 13, the outlet of sandrock filter 4 is connected by the water inlet of outlet conduit 15 with automatic backwashing lamination filter 6, the outlet of automatic backwashing lamination filter 6 is connected with upper field arm 10 and lower field arm 12 respectively by aqueduct 16, aqueduct 16 is provided with electronic flowmeter 7, the water outlet direction being positioned at electronic flowmeter 7 on aqueduct 16 is provided with gate valve 8, upper field arm 10 and lower field arm 12 are arranged on around fruit tree by support 9, upper field arm 10 is arranged on 50 centimeters above fruit tree, lower field arm 12 is arranged on distance ground 80, the lower section centimeters of fruit tree, upper field arm 10 and lower field arm 12 are designed with shower nozzle 11.
The method using present system sprinkling irrigation fruit tree is as follows:
1, around top fruit sprayer, first dig the infiltration ditch of wide 20CM, deep 15CM;
