Detailed Description
In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and examples.
A tree planting method in a soil moisture saturation region as shown in the accompanying drawings 1 to 2, which is characterized in that: the method comprises the following steps:
a. digging a planting pit: a planting pit 1 with a proper specification is excavated in a tree planting area according to the planting depth of trees (shown as 10 in fig. 1 and 2) and the size of soil balls (shown as 10a in fig. 2).
b. Placing in a tree planting bag: the planting bag 2 with the waterproof function is fully covered on the inner wall of the planting pit 1, and the top edge of the planting bag 2 is higher than the planting pit 1. Preferably, the tree planting bag 2 is preferably a PVC canvas tree planting bag, and the thickness is 0.5mm. The PVC canvas tree planting bag is utilized for waterproof treatment, so that the water in the underground water and the soil around the planting pit 1 is prevented from transversely flowing into the planting pit 1. The top edge of the tree planting bag 2 is higher than the planting pit 1, so that the tree planting bag 2 is prevented from being involved in the planting pit 1 along with the landfill process and losing the waterproof and waterproof effects on the planting pit 1 in the process of planting trees in the planting pit 1. After the planting hole 1 is covered with the planting bag 2, the part of the top of the planting bag 2 beyond the top of the planting hole is tightly fixed in the soil at two sides of the planting hole 1.
c. Building a soil base: after the tree planting bag 2 is paved, a soil base 3 with a truncated cone structure with a certain height is built at the center of the bottom of the tree planting bag 2. The soil base 3 of this structure has higher bearing capacity, avoids the retaining in planting hole 1 to cause its risk of collapsing.
d. And (3) lowering trees: the tree is placed in the planting pit 1, the bottom of the soil ball at the bottom of the tree is contacted with the top surface of the soil base 3, the top end of the soil ball is ensured to be higher than the planting pit 1 by a certain height (preferably, the height of the soil ball higher than the planting pit 1 is 10-20 cm), and the purpose is to avoid the situation that the top of the soil ball still leaks and breathes under extreme conditions (the planting pit 1 is filled with water due to natural factors), and the soil ball is completely immersed in the water to be necrotized.
e. Backfilling coarse yellow sand: and a coarse yellow sand layer 4 which is flush with the top surface of the soil base 3 is filled in the space between the side wall of the soil base 3 and the inner wall of the tree planting bag 2. Since the coarse yellow sand layer 4 has the characteristic of water permeability, a certain amount of water source can be stored in the planting pit 1.
f. And (3) setting a detection tube: at least two detection pipes 5 for detecting the water level in the coarse yellow sand layer 4 are inserted into the coarse yellow sand layer 4 along the circumferential space between the soil ball and the soil base 3, and the top ends of the detection pipes 5 are higher than the top of the soil ball by a certain distance. The height of the water storage level in the coarse yellow sand layer 4 in the planting pit 1 can be detected through the detection pipe 5 (the detection method can be used for detecting by extending a detection ruler into the detection pipe 5), so that water sources in the coarse yellow sand layer 4 are supplemented through the detection pipe 5 in drought time and festival or water is extracted when the water quantity is too much, the water quantity with stable height in the planting pit 1 is maintained, namely, tree roots in soil balls cannot be soaked due to the too much water quantity, and drought cannot be caused due to the too little water quantity.
g. Backfilling the covering layer: and backfilling a covering layer 6 on the top of the coarse yellow sand layer 4 until the covering layer is flush with the top of the soil ball. The soil balls are covered and buried through the covering layer 6, and preferably, the covering layer 6 is formed by mixing sandy soil according to the weight ratio of 1:2, which is beneficial to respiration of root systems and reduction of evaporation of water in the planting pit 1.
Preferably, the depth of the planting pit 1 is 1.5-2 times of the height of the soil ball, so that a certain amount of water source can be stored in the planting pit 1, and the tree can be evaporated by utilizing a certain amount of water source stored in the planting pit 1 in a drought environment with a longer period, so that the water required for survival of the tree is provided, and meanwhile, the contact distance between the soil ball and a water layer is increased, so that the long-term soaking necrosis of the soil ball of the tree is avoided.
In order to ensure that a sufficient amount of water source is stored in the planting pit 1, the height of the soil base 3 is more than or equal to 30cm. Meanwhile, the coarse yellow sand layer 4 has the same height, so that the storage capacity of a water source can be ensured, the drought resistance period of the tree is prolonged, and the possibility that the root system of the tree is soaked is eliminated.
The diameter of the planting pit 1 is more than 40cm larger than the maximum diameter of the soil ball. That is, after the tree is planted in the planting pit 1, the outer side of the soil ball is spaced by more than 20cm from the inner wall of the planting pit 1 (when the tree is planted, the soil ball is planted in the right center of the planting pit 1), so that after the tree is planted, a good growth space of a root system of the tree in loose and breathable soil is ensured, the root system is facilitated to grow, moisture stored in the planting pit can be evaporated quickly through the space, and the side wall of the soil ball is moistened, so that the tree can be energy-saving and moisture can be obtained quickly and timely when drought. The space can store the water source in the planting pit 1 in rainy season or artificial irrigation, so as to store the water source.
Because the porosity of the coarse yellow sand is larger, when the water source is replenished into the coarse yellow sand layer 4 through the bottom end of the detection tube 5, the coarse yellow sand is gathered at the port of the bottom of the detection tube 5, and cannot be effectively filled in the whole coarse yellow sand layer 4, so that the storage capacity of the water source in the planting pit 1 is reduced, and in order to store the maximum water source in the coarse yellow sand layer 4, in step f, a plurality of water seepage holes 51 are uniformly distributed on the outer wall of the detection tube 5 along the height direction of the outer wall. When the water quantity in the planting pit 1 is too small, the water source is supplemented into the coarse yellow sand layer 4 through the detection pipe 5, and when the water source is gathered at the port of the bottom, the water source is stored into the planting pit 1 through the water seepage holes 51 with different heights, and the mode can quickly and effectively store the water source in the coarse yellow sand layer 4 so as to prolong the moisturizing period of trees. In addition, the water seepage holes 51 can also enhance the air permeability of the root system at the outer side of the tree soil ball and discharge excessive water in the soil ball into the planting pit 1 through the water seepage holes 51, and meanwhile, the root system at the side wall of the soil ball is moistened through the water seepage holes 51 of the detection tube 5 when the water storage at the lower part of the planting pit 1 is evaporated, so that the activity of the tree root system and the luxuriant and rich branches and leaves are promoted.
In order to avoid the problem that coarse yellow sand in the coarse yellow sand layer 4 is extracted when the water in the planting pit 1 is more and needs to be extracted outwards, the side wall and the bottom end of the detection tube 5 are integrally wrapped with sand-proof gauze 7, and the top end of the detection tube is wrapped with detachable sand-proof gauze 7. The sand prevention gauze 7 can effectively avoid the problem that coarse yellow sand and a water source are simultaneously extracted from the water seepage holes 51 and the bottom end of the detection tube 5; the detachable sand-proof gauze 7 is arranged at the top end, so that the water storage level at the bottom of the tree pit is conveniently supplemented through the detection tube 5, and the blockage problem caused by sundries and the like entering the detection tube 5 is avoided.
In order to accurately and automatically control the water quantity height in the planting pit 1, a self-draining pipe 52 communicated with the detection pipe 5 is arranged at the position, facing the outer side of the planting pit 1, of the contact surface of the soil ball and the soil base 3 by the detection pipe 5. When the amount of rainwater stored in the planting pit 1 or the amount of water for artificial irrigation is too much, the rainwater is automatically discharged from the drain pipe 52 (preferably, the top end of the inner wall of the drain pipe 52 is flush with the top surface of the soil base 3 so as to avoid the situation that the water level in the planting pit 1 is higher than the top surface of the soil base 3 and the root system at the bottom of the soil ball is soaked in water to be necrotic), so that the water source with stable water level in the planting pit 1 is maintained, the problem that the root system is immersed due to too much water source is avoided, and the difficulty of manual extraction (including too low or too low water level caused by too high extraction amount) is solved. The excessive water source automatically discharged from the drain pipe 52 can be irrigated in the soil at both sides of the planting pit 1, and the plants such as lawns planted on the top of the soil can be moisturized.
In order to avoid the problem that the efficiency of the water supply is reduced by directly discharging a part of the water supply into the soil at both sides of the planting pit 1 through the probe pipe 5 during the water supply supplementing process, it is preferable that the self-discharging pipe 52 comprises an arc-shaped pipe portion 52a and a horizontal pipe portion 52b sequentially connected with the probe pipe 5, wherein the top of the inner wall of the horizontal pipe portion 52b is flush with the top surface of the soil base 3, and the arc-shaped pipe portion 52a is lower than the top surface of the soil base 3. The function is as follows: when the water source is replenished through the detection pipe 5, the water source flows downwards, but does not flow upwards in the arc-shaped pipe part 52a in a reverse direction, so that the water source can be fully replenished into the planting pit 1 when the water source is replenished; when the water amount is excessively supplied, the water rises through the arc-shaped pipe portion 52a into the horizontal pipe portion 52b and flows out into the soil outside the planting pit 1. And the quantity of the water is also detected by a detection ruler.
The principle of the invention is as follows: the planting pit is internally provided with a PVC canvas tree planting bag, a circular table type soil base is built at the pit bottom, trees are placed down, soil balls are exposed, a detection tube is placed between the soil balls and the tree planting bag, and coarse yellow sand and sand are backfilled. The tree keep-alive technical measure consists of four technical defense lines of water isolation of a PVC canvas tree planting bag, buffer watering of a circular table type soil base, water supplementing of a detection pipe, self-drainage, ventilation and keep-alive of exposed soil balls, and the survival rate of trees is greatly improved. The planting method has the advantages of convenient construction, high speed, low cost and good economic and social benefits.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
