Description

Technical Field

[0001] The invention belongs to the technical field of water-saving irrigation for afforestation, and particularly relates to an underground water-retaining seepage device for afforestation in waterless desert areas made by using old plastic liquid barrels. Background Art

[0002] Desert arid and semi-arid waterless irrigation areas are desertified due to lack of rain and agricultural irrigation conditions. Under these conditions, irrigation and watering for afforestation are usually carried out by vehicles and people, and water is replenished one tree at a time to keep it alive. The labor intensity is high and the cost of planting trees is high. Because of the lack of rain in arid and semi-arid areas, the soil moisture content is extremely low. The water for watering the seedlings is absorbed by the soil and evaporated in a very short time. The seedlings themselves have no water storage function. The process of absorbing water and nutrients is gradually and slowly absorbed. Most of the water is absorbed and dispersed by the soil and evaporated. The plant roots can only absorb a very small part of the water, resulting in water waste. Only when the seedlings grow up for three or four years and the root system grows and extends below the permafrost layer can they stably absorb the water that has not been evaporated by the soil, thereby meeting the water demand for growth and growing into large trees. At present, the use of farmland drip irrigation to irrigate and retain water for afforestation in desert areas is extremely costly. In addition, the economic development level in desert areas is low, and local people generally cannot afford the expensive drip irrigation equipment. Summary of the invention

[0003] In view of the problems existing in the existing afforestation in desertified areas, the present invention provides an underground water-retaining seepage device for afforestation in waterless desert areas made of old plastic barrels.

[0004] The technical scheme of the present invention is as follows: an underground water-retaining seeper for afforestation in waterless desert areas is made by using old plastic barrels, a conical water-permeable fixing plug is installed on the top cover of the old plastic barrel, a rain cloth fixing device is installed at the top mouth of the old plastic barrel through the conical water-permeable fixing plug, and a connecting pipe is installed on the side wall of the old plastic barrel. The connecting pipe is fixed to the side wall through a sealing ring, and a water-permeable porcelain head is installed at the end of the connecting pipe outside the wall. The old plastic barrel is buried under the ground surface, and most of the barrel corresponds to the position of the root system of the seedlings.

[0005] The tarp fixing device includes a tarp, a pressure strip, pins and a pressing plate. The tarp is fixed with the pressure strip. A hole matching the conical water seepage fixing plug is opened in the center of the tarp. The pressing plate on the pin fixes the pressure strips at the four corners to form a frame structure. When the old plastic barrel is buried in the ground, the pins at the four corners of the tarp are immediately inserted into the ground to fix the entire tarp fixing device. The tarp fixing device is located above the ground surface.

[0006] The present invention has the following significant effects: the present invention uses waste plastic barrels to be buried next to the roots of seedlings; rainwater flows into the barrel through the rain cloth and the conical permeable fixed plug, and the collected rainwater is slowly released into the soil of the seedling roots through the connecting pipe and the water-seepage porcelain head of the barrel wall in an infiltration manner, so as to meet the synchronous absorption of the fruit tree roots to the maximum extent, thereby achieving the effect of efficient water replenishment, water saving and water conservation. The infiltration irrigation is realized, which greatly saves the amount of irrigation water compared with the traditional irrigation method, and is suitable for seedling irrigation, water saving and water conservation in desert arid areas.

[0009] like Figure 1-Figure 3 As shown, an underground water-retaining seeper for afforestation in waterless desert areas is made of old plastic barrels. A conical permeable fixed plug 24 is installed on the top cover of the old plastic barrel body 10, and a rain cloth fixing device is installed at the top barrel mouth 14 of the old plastic barrel through the conical permeable fixed plug 24. A connecting pipe 13 is installed on the side wall of the old plastic barrel. The connecting pipe 13 is fixed to the side wall of the barrel body through a sealing ring 11, and a water seepage porcelain head 12 is installed at the end of the connecting pipe outside the barrel body wall. The old plastic barrel body 10 is buried under the ground, and most of the barrel body corresponds to the position of the root system of the seedlings.

[0010] The amount of water seepage depends on how much the exposed part of the water seepage magnetic head contacts the soil. The more the magnetic head leaks, the greater the water seepage is, and the less the magnetic head is exposed, the less water seepage is. Usually, the connecting pipe installed on the side wall of the old plastic barrel body 10 and its matching water seepage porcelain head are set according to the size of the seedlings and the size of the barrel body, usually 1-4 sets; another implementation method is that the connecting pipe is not required, and the barrel wall is directly connected to the water seepage porcelain head through a sealing ring. The material of the water seepage magnetic head is not limited to porcelain, pottery and plastic products, and it is better to release water slowly without forming drips.

[0011] The tarp fixing device includes a tarp 20, a pressure strip 21, pins 22 and a pressing plate 23. The tarp 20 is fixed by the pressure strip 21. A hole matching the conical water seepage fixing plug 24 is opened in the center of the tarp 20. The pressing plate 23 on the pins 22 fixes the pressure strips 21 at the four corners of the frame to form a frame-like structure. When the old plastic barrel is buried underground, the pins 22 at the four corners of the tarp are immediately inserted into the ground to fix the entire tarp fixing device. The tarp fixing device is located above the ground surface.

[0012] The rain cloth 20 can be made of a film for farmland, which forms a rainwater receiving shape when covered, so that water and fertilizer can flow into the barrel through the rain cloth and the conical permeable fixed plug.

[0013] The buried water-retaining seepage device of the present invention can be set according to the volume of the barrel, the size of the trees, and the number of trees. The barrel body is buried underground, and the barrel mouth is flush with or slightly lower than the floor line. A rain cloth is placed on it to form a fan-shaped surface to receive rainwater, which is convenient for water and liquid fertilizer to flow into the barrel; a conical permeable fixed plug with a seepage hole is installed on the barrel mouth to connect the barrel mouth and fix the rain cloth, and rainwater flows into the barrel along the mesh of the cone plug, while blocking the flow of mud and sand impurities into the barrel; after the buried barrel carrying the seedlings is set, rainwater can be directly received, or water can be directly poured onto the rain cloth to fill the barrel body. The seepage magnetic head device slowly releases water into the soil of the seedling root system. The seepage magnetic head on the barrel contacts the soil more, that is, the seepage amount is large, and the seepage magnetic head at the bottom of the barrel is exposed to the soil less, that is, the seepage amount is less than the exposed soil head, forming the upper magnetic head seepage greater than the lower magnetic head seepage, thereby ensuring that the root system in the critical seedling period is fully hydrated and conducive to growth. The water infiltration rate of the magnetic head is optimal when no dripping occurs, ensuring that the root soil is moistened, and the water is released slowly and continuously in sync with the water absorption by the plants, thus saving water and preventing it from evaporating.
