Description
Technical Field

Background
The design of vegetation is carried out on gardening projects such as buildings, municipal administration and the like without leaving vegetation, the common practice of supplementing water to the vegetation in arid areas is to lay water delivery lines on vegetation parks, then evenly distributed irrigates and sprays facilities, and the vegetation is irrigated on a regular (intermittent) or irregular basis by manually starting a switch so as to ensure the normal growth of the vegetation. Although the method can solve the problem of water shortage of vegetation at one time, for sandy soil areas, the water retention rate is extremely low, vegetation only has a nourishing effect during irrigation, when irrigation is stopped, water permeates into the ground, and the climate is dry, the water evaporates rapidly, so that the vegetation is in a water shortage state quickly, the survival rate of the vegetation is low, and even if the survival vegetation is in a dry and low color state due to water shortage. Such as continuous irrigation, requires a great deal of waste of water resources. Therefore, the research on the moisture preservation of horticultural vegetation in high-temperature arid water-deficient areas is urgent.
For foreign water-deficient areas such as the United states and France, water-retaining irrigation is carried out on large-area economic crops in agriculture and forestry, and according to the degree of water deficiency, the technical methods of flood irrigation, spray irrigation, infiltrating irrigation and the like are adopted, and in very water-deficient areas such as israel, drip irrigation and micro spray irrigation are adopted more often. However, under the condition of smaller vegetation areas such as garden lawns, automatic irrigation is basically used as an auxiliary mode for host irrigation, such as Canadian countries.
The urban scale of China is huge, the green land development is increasingly enlarged, but the water shortage is still serious, and the irrigation technology of vegetation such as lawns is relatively backward. The water storage and seepage system is established in developed cities such as Beijing city by 'rainwater utilization', and natural rainfall is effectively utilized by adopting the 'permeable pavement' technology, so that groundwater can be directly supplemented. The large-scale woodland and vegetation areas are utilized to form huge root systems of plants, the precipitation medium-term is formed into a 'sponge' area, the plants of various root systems firmly lock the moisture in the soil, and the precipitation is quickly absorbed, so that the effect is better. The basic water retention method for planting vegetation such as lawns and the like in northwest areas is low in rainfall and unbalanced, the basic water retention method still takes artificial irrigation as a main part, natural water collection and infiltration irrigation as auxiliary technical measures, and the water retention effect is poor.

According to meteorological data, the stone river rainy season is generally concentrated in spring and summer (4, 5, 6 and 7 months), and the natural precipitation is more in this stage, the water shortage of the water collecting ditch is less, the vegetation water is more sufficient, and natural growth and maintenance are carried out. It should be noted that if vegetation is planted in the germination stage, the soil humidity should be controlled at 75-85%, and the soil humidity should be controlled at about 70% in the seedling growth stage, so as to avoid excessive water and rotten roots. The control method is to adjust the threshold value of the sensing type hygrothermograph to the corresponding scale.
2. Water retention in water shortage period
(1) Ensure that the fermentation tank and the water storage tank have enough water storage capacity. The fermentation vat and the water storage tank are sources for vegetation water retention, and the water source of the water storage tank is as follows: the natural precipitation collected from the irrigation ditch and the water collecting ditch designs the same elevation at the bottom of the irrigation ditch and the water collecting ditch, and the water after water collection can naturally flow into the water storage pool; secondly, shower bath wastewater; thirdly, the annual precipitation amount in the stone river area is small (about 150 mm) and the precipitation times are limited (about 40 times); thirdly, natural water collected outside the vegetation area. Therefore, natural precipitation cannot meet the water storage requirement of the water storage tank, and therefore the water source of the water storage tank mainly comes from shower bath wastewater in the water shortage period.
(2) Irrigation ditches store water. Irrigation ditch one end links to each other with the tank, other segmentation links to each other with the water catch bowl, irrigation ditch except having water collecting function and irrigation function, in the junction with the tank and other corresponding points set up irrigation control sluice, tank department sluice is butterfly, other be the picture peg state when collecting natural precipitation, irrigation ditch and water catch bowl are sufficient like the water source this moment, can provide moist condition for vegetation nature, when the lack of water reaches the threshold value that vegetation needs humidity like the hygrometer linkage triggers the tank water pump, start the retaining moisturizing procedure, the water source with the tank is replenished to irrigation ditch and water catch bowl in.
(3) And water is stored in the water collecting ditch. The water collecting ditch must keep a certain height of constant water level, and when the water shortage reaches a threshold value, the water supply flow of the water storage tank is started, and the principle is the same as that of the irrigation ditch. When water is rich, firstly, natural evaporation provides water vapor for vegetation through the shunt tubes, and if vegetation water is excessive, the vegetation water flows into the water collecting tank through the shunt tubes, so that the effect of natural circulation water supply is achieved.
(4) The water source of the water collecting ditch flows into (or evaporates) the vegetation soil through the shunt tubes, and the sponge has the functions of absorbing water and preventing water seepage of the plastic film, so that the water of the soil is continuously kept for the normal growth of the vegetation.
(5) Under the condition of extreme lack of water, the water storage tank is about to dry up, and at the moment, a valve-controlled hygrometer triggers a municipal pipe network to intermittently irrigate vegetation subareas until the water humidity required by vegetation is reached, and the sprinkling irrigation is stopped.
(6) In the germination period of vegetation seeds or in the growth period of vegetation seedlings, under the condition of excessive high-temperature sunlight, a sunshade net is adopted to cover the vegetation, so that the sun-shading of the burning sun is avoided temporarily, and the technical measure of reducing the evaporation of water is adopted.
Economic effect
1. Natural water collection. According to the related meteorological data, the area of the stone river is 460 square kilometers, annual precipitation is about 150mm, annual evaporation is 1000mm, precipitation times are 40, vegetation water demand is 600mm, and therefore the vegetation water shortage amount is about according to a general planting and maintenance method: 1000+ (600-150) =1450 mm, the water volume can be collected intensively for the scheme year: 40 (precipitation times) ×50000 (reservoir capacity)/5000 (vegetation area) =400 mm. The water shortage amount is reduced by 400mm, municipal water supply can be saved by 400 x 5000=2000 t, and water transmission and power supply cost is saved: 2000 x 4 (industrial electricity price) +2000 x 0.25 (water delivery price per square meter) =8500 yuan. Labor cost saving: 5 (month) x 2 (person) x 5000=50000 yuan. And the cost can be saved by 58500 yuan.
2. Bathroom waste water usage. The bathroom waste water is the main water-holding scheme of the scheme, the bathroom spraying is calculated according to 15, each time each person bathes for 0.5 hour, each time each person flows 0.15 cubic meter, 8 lanes of the natatorium are standard, the number of people showering every day is calculated according to 300 people, and the annual waste water flow: 360 x 0.15 x 300=16200 cubic meters (t), saving water and electricity supply fee: 16200×4 (industrial electricity price) +16200×0.25 (water delivery price per square meter) = 68850 yuan. Annual neutralising carbon dioxide: 5000 square meters by 20 grams (carbon dioxide uptake per square meter of vegetation) by 360 days = 36 tons; the labor cost is not repeatedly calculated.
The scheme can save about 12 tens of thousands of yuan (without carbon dioxide treatment).
Working principle: the natural precipitation technology is collected by adopting a fermentation tank, a water storage tank, bathroom wastewater and natural precipitation as main water sources, irrigation ditches and water collecting ditches, the technology of providing water vapor by a shunt pipe and collecting vegetation redundant water is adopted, and the technology of a distributed comprehensive water supply system such as automatic water pumping and irrigation is adopted, so that the energy-saving and environment-friendly effects are obvious.
