Description

Technical Field

[0001] The invention relates to the technical field of forest tree introduction, in particular to a double-membrane water-fixing forest tree cultivation technology. Background Art

[0002] Tree introduction refers to the practice of domesticating and cultivating a particular tree species and planting it in areas outside its natural distribution. Tree species that grow in their natural range are called native species, while those introduced to areas outside their natural distribution are called exotic species.

[0003] In the actual application process of this patented equipment, the pit depth of the conventional forest cultivation method is only 40 to 60 centimeters. Its advantage is that the roots of the trees can fully absorb the moisture and nutrients from the soil surface. However, when the bottom soil is hard, dry and water-deficient, it is very difficult for the seedlings to survive, which is not conducive to actual application and operation. Summary of the Invention

[0004] One of the purposes of the present invention is to provide a double-film water-fixing forest cultivation technology.

[0005] 8. To achieve the above objectives, the present invention adopts a technical solution: a double-film water-fixing forest cultivation technology, comprising the following steps:

[0006] Step 1: Introduce the plants, transplant them into the dug pit, backfill the soil to a certain height after transplanting, and then compact the backfilled soil;

[0007] Step 2: Laying: Lay the first layer of agricultural film on the outside of the plants and above the compacted soil. Make some air holes at equal intervals on the top of the first layer of agricultural film.

[0008] Step 3: Add fertilizer, add an appropriate amount of soil with fertilizer according to the size of the soil ball at the bottom of the plant;

[0009] Step 4: Watering: After adding the soil with fertilizer, add enough water. After the plants are firmly planted, lay the second layer of agricultural film.

[0010] Step 5: Cover the soil. Drill some air holes at equal intervals on the top of the second layer of agricultural film. After the holes are drilled, cover with a certain amount of loose soil.

[0011] Step 6: Rehydrate. After waiting for a certain number of days, add water to the heel appropriately according to the condition of the plant.

[0012] Preferably, in the step 1, the spacing between transplanted plants should be at least not less than five meters, and the size of the soil pit should not be less than 1.5 cubic meters. After the depth is reached, 50 centimeters of loose soil should be backfilled.

[0013] Preferably, in step 2, the first layer of agricultural film can effectively isolate the outside cold air and reduce soil moisture evaporation.

[0014] Preferably, in step three, adding appropriately fertilized soil helps the plants absorb nutrients.

[0015] Preferably, in step four, sufficient water is poured to provide the plants with sufficient moisture, and at the same time, the second layer of agricultural film can further isolate the external cold air and reduce soil moisture evaporation.

[0016] Preferably, in step five, the pores on the second layer of agricultural film allow rainwater from outside to penetrate in, so as to water the roots of the plants, and the loose soil not higher than ten centimeters above the ground can effectively store some water.

[0017] Preferably, in step six, after forty days, the root water can be appropriately supplemented according to the growth of the plant to increase the probability of survival.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention can effectively isolate the cold air from the outside and reduce the evaporation of soil moisture through the double-layer membrane structure, providing a stable growth environment for trees. Reducing water evaporation means reducing the number of irrigation times and the amount of water used, which helps to achieve water-saving cultivation. In arid and semi-arid areas with scarce water resources, the double-membrane water-fixing technology can significantly improve the survival rate of trees. If it is a road green belt, it can be designed as a trench planting with a width of 1.2 meters and a depth of 1.2 meters. This not only makes it more convenient to cover the two layers of film but also creates a good growth environment for lateral roots. This deep excavation and backfilling covering technology is not only suitable for hard and crusty soils on urban roads, highways and river banks, but also for planting various types of forestry and fruit industries. After surviving, trees can also grow naturally in semi-arid areas. The fundamental reason is that the upper and lower membranes fully absorb the crustal moisture in the space that contacts the loose soil during the day and night temperature conversion process to ensure the moisture of the tree roots. In other words, the upper and lower membranes play a role in retaining moisture, fertilizer and heat for the healthy development of the tree roots. In loose soil, it plays a key role in the rapid growth of trees. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Step 3: Add fertilizer, add an appropriate amount of soil with fertilizer according to the size of the soil ball at the bottom of the plant;

[0028] Step 4: Watering: After adding the soil with fertilizer, add enough water. After the plants are firmly planted, lay the second layer of agricultural film.

[0029] Step 5: Cover the soil, open some air holes at equal distances on the top of the second layer of agricultural film, and cover a certain amount of voids after opening.

[0030] Step 6: Rehydrate. After waiting for a certain number of days, add water to the heel appropriately according to the condition of the plant.

[0031] Step 1: The spacing between transplanted plants should be at least not less than five meters, and the size of the soil pit should not be less than 1.5 cubic meters. After the depth is reached, fill it with 50 centimeters of loose soil.

[0032] Step 2: The first layer of agricultural film can effectively isolate the outside cold air and reduce soil moisture evaporation.

[0033] Step three, by adding appropriately fertilized soil, helps the plants absorb nutrients.

[0034] Step 4: Water the plants sufficiently to provide them with enough moisture. At the same time, the second layer of agricultural film can further isolate them from the cold air outside and reduce soil moisture evaporation.

[0035] Step 5. The pores on the second layer of agricultural film allow rainwater from outside to penetrate, so as to water the roots of the plants. Covering it with loose soil no higher than ten centimeters above the ground can effectively store some water.

[0036] Step six: After forty days, you can add appropriate amount of water to the roots according to the growth of the plant to increase the probability of survival.

[0037] Working principle:

[0038] When used, the double-layer membrane structure effectively isolates cold air from the outside world and reduces soil evaporation, providing a stable growth environment for trees. Reduced evaporation means fewer irrigations and lower water consumption, contributing to water-saving cultivation. In arid and semi-arid areas with water scarcity, this double-layer water-retention technology can significantly improve tree survival rates. For roadside green belts, trench planting can be designed with a width of 1.2 meters and a depth of 1.2 meters. This not only facilitates double-layer membrane coverage but also creates a favorable growth environment for lateral roots. This deep excavation and backfill membrane covering technique is not only suitable for hard, crusty soils along urban roads, highways, and riverbanks, but also for various types of forestry and fruit production. Once established, trees can also grow naturally in semi-arid areas. The fundamental reason for this is that the upper and lower membranes, in contact with the loose soil during the diurnal temperature transition, absorb moisture from the earth's crust, ensuring water retention for the tree roots. In other words, the upper and lower membranes retain moisture, fertilizer, and heat for the healthy development of tree roots, playing a crucial role in promoting rapid tree growth in loose soil.

Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and description merely illustrate the principles of the present invention.
