Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forestry planting, in particular to a tree planting and maintenance metering water storage and replenishment method. BACKGROUND

[0002] Due to less rainfall, strong wind and drought in arid and semi-arid regions, evaporation is large, the surface temperature is high in summer, the soil organic matter is low, the water content is low, the soil is sandy in the plant layer, there is no surface groundwater, and no measures are taken to prevent seepage, evaporation and high temperature at the bottom, around and top of the root system of planted trees and shrubs; water is irrigated by car in planting sites without water source and power supply, and the shortest time for watering trees is 25 to 30 days. Due to different depths and sizes of water storage holes, water is splashed and leaked during irrigation, so that each tree is irrigated with different amounts of water, some roots absorb more water and some absorb less, which causes trees to wither and die due to lack of water. The method of pipe network sprinkling irrigation, in the process of spraying, dry hot air evaporation, strong wind blowing, high temperature evaporation of the ground surface, less than 30% of the water can reach the plant root system, the root system of trees and shrubs grows deep and the leaves block the spray, which is not suitable for sprinkling irrigation. The method of drip irrigation pipe network, the actual drip irrigation also exists evaporation in the process of water dripping into the ground and evaporation of the upper soil absorbing water from the lower soil after drip irrigation. In addition, the distance between the groundwater well and the site is far in arid and semi-arid regions, the pipe network is laid in a large area and a long distance, the configuration cost of power, pump station power, water well facilities and equipment is high, the high slope and low land water supply is uneven, the water pipe is frozen and cracked in winter, and other faults, because of the limitation of underground water source, the site far from the well also needs to be irrigated by water truck. The method of buried underground pipe network irrigation, there are problems such as underground water pipe blockage, water leakage, winter land freezing, land cracking, pipe crushing, uneven water dripping, water running and water spouting, pipe water freezing and cracking, and difficult drainage. The method of punching holes around the tree root system and directly feeding water into the holes to replenish water for trees, due to the fact that most of the soil below the surface layer in arid and semi-arid grassland regions is sandy soil, the water loss amount of the hole around and bottom is large, if the soil is clay with poor water permeability, the water storage amount in the hole is small, the water will return to the ground and evaporate, in addition, the water storage in the water feeding device in the hole is easy to freeze and break in the north with large diurnal temperature difference, the above faults are difficult to repair, the cost of checking, repairing and replacing is high, the tree water replenishment time is delayed, and the tree maintenance quality is difficult to guarantee.

[0005] The present application provides a tree planting and maintenance water storage and replenishment method, comprising the following steps:

[0006] S1, a water storage and infiltration ditch with a width of 10-50 cm and a depth of 30-120 cm is dug around the tree root system at a position 50-120 cm away from the tree root, a seepage prevention mat is laid on the bottom and side wall of the water storage and infiltration ditch to form a seepage prevention layer, nutrient and organic matter soil is filled on the outside of the seepage prevention layer to form a water storage and infiltration layer, a grass screen is laid on the outside of the water storage and infiltration layer to form a water interception layer, nutrient and organic matter soil is filled on the outside of the water interception layer, a water replenishment depth control pipe is buried, the buried depth is 10-50 cm, 3-25 cm of nutrient and organic matter soil is filled in the water replenishment depth control pipe from bottom to top, a seepage prevention cloth is laid on the surface of the nutrient and organic matter soil in the water storage and infiltration ditch, an opening is arranged at the contact position of the seepage prevention cloth and the water replenishment depth control pipe, and 3-10 cm of soil is covered on the surface of the seepage prevention cloth;

[0007] S2, a water storage pipe, an overflow irrigation pipe and a drip irrigation pipe are installed on the water replenishment depth control pipe, the water storage pipe is connected with the top of the water replenishment depth control pipe, one end of the overflow irrigation pipe is connected with the water replenishment depth control pipe, the other end of the overflow irrigation pipe is connected with the upper part of the water storage pipe, one end of the drip irrigation pipe is connected with the water replenishment depth control pipe, the other end of the drip irrigation pipe is connected with the bottom of the water storage pipe, and a water flow distribution disc is installed in the water replenishment depth control pipe;

[0008] S3, a plurality of water collecting holes are dug around the tree root system at a position 30 cm away from the water storage pipe, the spacing between adjacent water collecting holes is 30-100 cm, a water collecting ditch connected with the water collecting holes is built along the periphery of the water collecting holes, the water collecting holes are filled with nutrient and organic matter soil, water seepage holes are arranged on the bottom of the water collecting holes, water seepage depth control pipes are installed in the water seepage holes, the water seepage depth control pipes are filled with nutrient and organic matter soil to a distance of 3-45 cm from the pipe opening, a positioning float evaporation prevention cover is arranged on the water seepage holes, the lower end of the positioning float evaporation prevention cover is fixed in the water seepage depth control pipe, and impurity protection covers are arranged at the hole openings of the water collecting holes.

[0009] The present application has at least the following beneficial effects:

[0010] 1. The water storage and infiltration ditch is dug around the tree root system, the seepage prevention layer, the water storage and infiltration layer, the water interception layer and the seepage prevention cloth are arranged in the ditch, and the water is seeped and irrigated into the soil in the root growth area through the cooperation of the above-mentioned layers, which effectively prevents water and fertilizer loss and water evaporation, the large amount of nutrient and organic matter soil filled in the ditch forms a water storage and infiltration reservoir with high water holding rate and long water retention time, which can continuously maintain sufficient nutrients and water absorbed by the tree root system, increase soil fertility and increase organic matter.

[0011] 2、The water storage pipe can flow into the soil from top to bottom without increasing pressure (power), and the upper part of the water storage pipe is provided with an overflow irrigation pipe leading to a water supplement depth control pipe when the water level in the water storage pipe reaches the position of the upper opening of the overflow irrigation pipe, the overflow irrigation pipe inputs more water into the water supplement depth control pipe, and then the water supplement depth control pipe inputs water into the surrounding soil and into the soil around the tree roots, at this time the soil moisture content is low, the water absorption and penetration are fast, and the water input is large, and as the soil water absorption decreases, the water level in the water supplement depth control pipe reaches the water outlet position of the overflow irrigation pipe, the float switch lifts the soft rubber water pipe to fold and close, and the overflow irrigation pipe stops water input. The drip irrigation pipe leading to the water supplement depth control pipe is arranged below the water storage pipe, and only when the drip irrigation pipe drips water, the water input of the water storage pipe is greater than the overflow and drip water of one water supplement depth control pipe and less than the overflow and drip water of two water supplement depth control pipes. Therefore, the water of each water supplement depth control pipe can be added to the closed water level, and after the water storage pipe is filled with water, the water in the water storage pipe is dripped into the soil below the water supplement depth control pipe through the drip irrigation pipe. Since the overflow water input (more) + drip irrigation water penetration (less) is adopted, the water holding capacity of the tree root growth area can be met, most of the water is intercepted by the interception water layer, and the soil around the tree roots is accumulated with sufficient water, and after the soil around the tree roots is accumulated with sufficient water, the water gradually penetrates into the soil below the interception water layer. According to the area and volume of the soil in the tree root growth area, the water supplement amount is determined, (the water amount input from the overflow irrigation pipe to the water supplement depth control pipe + the water storage amount of the water storage pipe = the water storage amount of the root growth area) the water storage amount of the water storage pipe is determined, the water input and drip water amount of the water supplement depth control pipe, and the purpose of metering water supplement is achieved. The water flow distribution disc is installed in the water supplement depth control pipe, and the pipe is filled with nutrient soil to reduce the scouring force of water, and the two can disperse water flow to prevent water flow from directly scouring the soil below to form voids and filter impurities and harmful elements.

[0012] 3、The overflow irrigation pipe and the drip irrigation pipe can be arranged inside or outside the water supplement depth control pipe and the water storage pipe. When arranged inside, it is mainly used for trees with small water demand; when arranged outside, it is mainly used for trees with large water demand. Moreover, the water supplement device is suitable for use in remote sandy, drought, high-temperature, and cold climate environments, is convenient for transportation and installation, has low failure rate, and is suitable for use in water and electricity deficient fields for plant planting and tree planting and maintenance in open-pit mine spoil sites.

[0013] 4. By installing impermeable fabric, water can be prevented from seeping back to the ground, reducing evaporation. It also allows the nutrient-rich organic soil with a large water storage capacity in the seepage trench to be integrated with the water replenishment depth control pipe. In a climate with large temperature differences between day and night, water has room to undergo liquefaction and vaporization, which can accelerate the infiltration of soil with high water content to soil with low water content. At the same time, because the soil temperature in the water replenishment depth control pipe and the seepage trench is higher than outside and is constant, trees can be watered earlier or later in spring and autumn.

[0014] 5. Water-gathering pits can collect more rainwater and snowmelt into the pit, transporting and storing more rainwater and nutrients into the soil around the tree roots. At the same time, they can also provide the nutrients needed for the survival and reproduction of soil organisms and microorganisms, thereby improving soil permeability. Attached Figure Description
