Description

Technical Field

[0001] The invention belongs to a water-saving tree planting method in desert arid areas. Background Art

[0002] Pressure irrigation is now often used for tree planting in deserts and arid and rainless areas. This method first uses a pressurized water gun to spray a stream of water to punch a small hole with a diameter of several centimeters and a depth of one meter on the sand, then quickly plant the seedling in the small hole, and then backfill the small hole with soil, so that digging, planting, backfilling, and watering are formed in one go. The advantage of this method is that it reduces the disturbance of the ground by planting, and can temporarily form a water-retaining and anti-seepage layer. Only about 10 liters of water are needed for planting each tree, and the survival rate of seedlings can be increased to 90%. However, the disadvantage of this method is that the cost of planting trees is high, and high-pressure spraying equipment, power equipment, transportation and water delivery equipment are required, and the installation, use and maintenance costs are high; it also needs to rely on a stable water supply, but water resources are scarce in desert areas, making it difficult to promote and use; the maintenance technology after tree planting is complex and relies on continuous watering maintenance.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described in conjunction with specific embodiments below, but the following embodiments are only preferred embodiments of the present invention, not all.

The construction methods in the following embodiments, unless otherwise specified, are all conventional methods. The materials, devices, equipment, etc. used in the following embodiments, unless otherwise specified, can all be obtained from commercial channels.

[0018] Example 1: Figures 1 to 3 , Figure 6 to Figure 7 As shown, a water-saving tree planting method in arid desert areas comprises the following steps: drilling a seedling planting hole on arid desert planting ground 9 with a punching and expansion tool, and at the same time, using the punching and expansion tool to squeeze and expand the hole wall at the bottom of the seedling planting hole toward the periphery, burying a water storage bag 6 with an opening upward in the expanded hole wall; injecting water into the water storage bag, or injecting water into the water storage bag with a punching and expansion tool and injecting water into the hole while removing the punching and expansion tool; planting a seedling 8 in the seedling planting hole, with the bottom end of the seedling root located at the upper end of the water storage bag; squeezing the ground on both sides of the seedling planting hole to close the hole; setting a moisture retaining partition 7 around the ground of the seedling stem at the hole mouth; and covering the surrounding part of the moisture retaining partition with sand.

[0019] It also includes watering the implanted saplings using drip irrigation technology. During watering, the drip irrigation pipe is inserted from the gap between the tree hole 72 of the moisturizing partition 7 and the sapling stem, and the water outlet of the drip irrigation pipe is located at the bottom of the tree stem at the lower end of the middle part of the moisturizing partition.

[0020] like Figures 1 to 3As shown, the punching and expansion tool is: the punching tube 2 is a hollow steel tube with an inner diameter of 3.5 to 4 cm, and the lower end of the punching tube is a round head 23, so as to facilitate the lower part of the punching tube to be inserted into the tree planting ground 9, and the lower peripheral wall of the punching tube is longitudinally provided with a plurality of spring-type extension holes 21 at intervals, and a punching foot tube 3 perpendicular to the axial center line of the punching tube is provided on one side of the lower part of the punching tube at the upper end of the spring-type extension hole, so as to facilitate stepping on or pressing down the punching tube so that its lower part is vertically inserted into the tree planting ground 9. An expansion tube 4 is slidably mounted inside the pressure hole tube, and the lower end of the expansion tube is supported on the lower end of the pressure hole tube. The outer peripheral wall of the lower part of the expansion tube corresponding to the hole through which the spring piece extends is a plurality of expansion spring pieces 41 longitudinally arranged at intervals. When each expansion spring piece is pressurized, it can bend in an arc shape and extend from the corresponding spring piece extending hole 21 to form an expanded sphere. The upper end of the expansion tube is located outside the upper end of the pressure hole tube to form a first water pipe joint 42, so as to facilitate the connection of a water pipe and inject water into the water storage bag 6 and the seedling hole through the expansion tube. A tube strip slot 22 is longitudinally provided on the hole-pressing tube wall on the other side of the upper end of the hole-pressing foot-operated tube. The inner end of the expansion tube pedal 1, which is perpendicular to the axis of the hole-pressing tube, is fixed on the outer wall of the expansion tube 4 in the upper part of the tube strip slot 22. The expansion tube pedal 1 is stepped on or pressed down to move the expansion tube 4 downward in the hole-pressing tube. When each expansion spring piece is pressurized, it can bend in an arc shape from the corresponding spring piece to the strip hole 21, so that the punching expansion tool can squeeze the expansion hole wall toward the periphery at the bottom of the seedling hole to form an expanded sphere.

[0021] like Figure 6 As shown, the moisturizing partition 7 is made of plastic cloth or plastic plate with a thickness of 0.1mm to 0.5mm, and is in the shape of a disc with a radius of 24cm to 40cm. A tree hole 72 with a diameter of 2cm is provided in the center of the moisturizing partition for the sapling pole to pass through, and an opening slit 71 is provided between the tree hole and the periphery of the moisturizing partition so that the moisturizing partitions are staggered at the opening slit, so that the cross section of the moisturizing partition is conical when used on the ground.

[0022] The water storage bag is a bag body with an opening facing upward, which is made of plastic cloth with a thickness of 0.3-0.4 mm. The bag body is a round or rectangular bag body with a capacity of 3-5 liters of water.

[0023] The water-saving tree planting method in desert arid areas includes the following specific steps: (1) The round head 23 at the lower end of the punching and expanding tool is held against the middle of the inner bottom of the plastic bag body 6 with the opening upward, and then held against the arid planting ground 9 where the seedling holes are to be drilled in the desert. The punching and expanding tool 2 is stepped on or pressed by hand to make the lower end of the punching and expanding tool 2 press against the middle of the inner bottom of the plastic bag body and vertically penetrate into the arid planting ground to form a seedling hole. The seedling hole is a vertical tube hole with a depth of 35 to 40 cm. Then the expansion tube tread 1 is stepped on with the foot, and the expansion tube tread moves downward along the tread groove 22 on the punching and expanding tool, so that the expansion tube moves downward in the punching and expanding tool and the expansion springs on the outer peripheral wall of the lower part of the expansion tube are pressed from the corresponding springs at the lower part of the punching and expanding tool 2 into the strip hole and bend in an arc shape. The extended springs sequentially squeeze the inner wall and the outer sand layer of the plastic bag body, forming a plastic bag body with an upwardly expanding opening buried in the wall of the expansion hole.

[0024] (2) Inject water into the water storage bag, or inject water 10 into the water storage bag using a punching expansion tool, that is, connect the first water pipe joint 42 at the upper end of the expansion tube to the water pipe 5 and inject water into the water storage bag and the seedling hole through the expansion tube and the expansion spring and the spring extending strip hole. After the water storage bag is filled with water, move the expansion tube pedal 1 upward, and the expansion tube pedal moves upward along the pedal strip groove hole on the hole pressing tube, so that the expansion tube also moves upward in the hole pressing tube and the expansion springs on the lower outer peripheral wall of the expansion tube are reset, and then pull out the punching expansion tool while injecting water 10 into the hole.

[0025] (3) Plant the seedling 8 in the seedling hole, with the bottom of the seedling root 81 located at the top of the water storage bag, keep the seedling upright, and plant 2 seedlings per hole at a depth of 8 cm above the root soil line. The seedlings are 1-year-old Class II seedlings with a length of 25 to 30 cm. When planting, perform protective pruning on the seedling roots, cut off injured roots, shorten the excessive main roots and lateral roots, dip the roots in a hygroscopic agent, ABT rooting powder, and soak the roots in ABT rooting powder at a concentration of 500 to 1000 ppm and a soaking concentration of 500 to 1000 ppm for more than 6 hours, and then plant them immediately.

[0026] (4) Squeeze the ground on both sides of the planting hole, then step on the ground on both sides of the planting hole to close the hole, then lift the seedling 2cm, and then step on the ground on both sides of the planting hole to make it firm.

[0027] (5) A moisturizing partition 7 is arranged around the ground of the seedling pole at the hole, and a gap of about 1 to 2 cm is arranged between the lower end of the middle part of the moisturizing partition and the ground. When the moisturizing partition is used on the ground, its cross section is conical, which is conducive to the formation of a temperature difference between the upper and lower end surfaces of the moisturizing partition. The moisture at the lower end of the moisturizing partition can condense into water droplets for absorption by the seedling.

[0028] (6) Cover the perimeter of the moisturizing baffle with sand and soil. Later, use drip irrigation technology to water the implanted seedlings. When watering, the drip irrigation pipe is inserted from the gap between the tree hole of the moisturizing baffle and the stem of the seedling. The water outlet of the drip irrigation pipe is located at the bottom of the tree stem at the lower middle end of the moisturizing baffle.

[0029] Example 2: Figure 4 and Figure 5 As shown, different from Example 1, the punching and expansion tool can also be: the hole-pressing tube 2 is a hollow steel tube with an outer diameter of 3 to 4 cm, the lower end of the hole-pressing tube is a round head 23, and a water outlet 24 is provided on the lower peripheral wall of the hole-pressing tube. A hole-pressing pedal tube 3 perpendicular to the axial center line of the hole-pressing tube is provided on one side of the lower part of the hole-pressing tube. The inner wall of the expansion tube 4 is slidably fitted on the outer wall of the hole-pressing tube 2, and the lower end of the expansion tube is supported on the upper edge of the round head at the lower end of the hole-pressing tube. A plurality of expansion spring pieces 41 are longitudinally provided at intervals on the outer peripheral wall of the lower part of the expansion tube. The upper end of the hole-pressing tube is located outside the upper end of the expansion tube to form a second water pipe joint 25, so as to facilitate the connection of a water pipe with water and inject water into the water storage bag and the seedling hole through the expansion tube. A tube strip slot 22 is longitudinally provided on the expansion tube wall corresponding to one side of the hole-pressing foot tube for the hole-pressing foot tube to move up and down. The outer side of the hole-pressing foot tube passes through the tube strip slot 22 and is located outside the tube strip slot. An expansion tube pedal 1 perpendicular to the axis line of the hole-pressing tube is provided on the expansion tube wall on the other side of the upper end of the hole-pressing foot tube. Pressing down the expansion tube pedal 1 can make the expansion tube move downward along the outside of the hole-pressing tube, and each expansion spring piece is pressed to bend outward in a semicircle, so that the punching expansion tool can squeeze the expansion hole wall toward the periphery at the bottom of the seedling hole to form an expanded spherical space.

[0030] When in use, the round head at the lower end of the hole-pressing tube of the punching and expansion tool is held against the middle of the inner bottom of the water storage bag, and then held against the dry tree planting ground at the desert seedling hole position, and the foot is stepped on the hole-pressing foot pedal tube to make the lower end of the hole-pressing tube press against the middle of the inner bottom of the water storage bag and vertically penetrate into the dry tree planting ground to form a seedling hole. Then the foot is stepped on the expansion tube pedal tube, so that the expansion tube moves downward along the hole-pressing tube and the expansion springs on the outer peripheral wall of the lower part of the expansion tube are compressed to bend outward in an arc shape and extend outward, and the extended springs squeeze the inner wall and the outer sand layer of the water storage bag in turn, forming a water storage bag that is buried in the wall of the expansion hole and expands upward. When water 10 is injected into the water storage bag by using the punching and expanding tool, the second water pipe joint 25 at the upper end of the hole-pressing pipe is connected to the water pipe 5 with water, and water is injected into the water storage bag and the seedling hole through the water outlet 24 at the bottom of the hole-pressing pipe. After the water storage bag is filled with water, the expansion pipe step tube 1 is moved upward, and the expansion pipe step tube moves upward along the step tube groove on the hole-pressing pipe, so that the expansion pipe moves upward along the hole-pressing pipe and the expansion springs on the lower peripheral wall of the expansion pipe are reset, and then the punching and expanding tool is pulled out while injecting water 10 into the hole. The rest is the same as in Example 1, so it will not be repeated.

[0031] The comparison conditions between the embodiment of the present invention and the traditional tree planting method are as follows: (1) The test conditions are the same, that is, the Tengger Desert area, the same adjacent acres of land, the same number of seedlings per acre, 500 seedlings per acre, and the seedlings are drought-resistant Tamarix. The test data are recorded after 365 days of tree planting as follows. Comparison method 1 is the traditional pit digging, watering, planting seedlings, filling the pit with soil, and regular watering and maintenance; comparison method 2 is the traditional pressure irrigation planting method (as described in the previous section), and the test data are as follows: (1) Table 1:

[0032] (2) Table 1 shows that the various indicators of the tree planting seedlings of each embodiment of the present invention are better than those of the traditional tree planting method. The annual water consumption (liter / plant) of the present invention saves 66-70% of water compared with the traditional tree planting method; the survival rate is increased to 93%; the water utilization efficiency is increased to 80%; the cost of tree planting tools is reduced to 50 yuan per tree. The present invention has a good use effect and has the advantages of saving labor and labor during construction, simple construction, fast speed, material saving, high efficiency and strong practicality.
