Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
The following is a detailed description of a double-layer soil stabilization transplanting method for a coarse sandy soil tree provided by an embodiment of the present invention.
A double-layer soil stabilization transplanting method for a coarse sandy soil tree comprises the following steps:
(1) according to the size of the root with soil dug up as required, the surface soil of the ground for planting trees is shoveled until new soil is exposed, and then an annular ditch is dug towards the outer edge of the root with soil. In this example, the thickness of the topsoil was 3 to 7cm, and the width and depth of the annular trench was 20cm × 20 cm. The plant size is planted by matching with the common coarse sandy soil.
(2) Pouring rice water from the base of the tree to immerse the soil layer with soil roots; the thickness of the soil layer can be detected by using an earth drill. The operation is to adopt rice water to carry out inner layer solidification on the root with soil.
(3) And (3) after the surface soil at the root part of the carried soil is dried, sawing the peripheral soil at the root part of the carried soil downwards by the annular trench to obtain a lower cutting trench, and mixing the peripheral soil with the soil dug in the step (1) to be used as native soil and placing the native soil on the ground. If the root with the soil of the sawed peripheral soil still collapses, the rice water is poured to the base of the tree towards the inner side of the annular groove while the root with the soil is cut down, so that the inner-layer soil is prevented from collapsing continuously, and the cut soil is placed on the ground as the native soil.
(4) Spraying bactericide and rooting agent to the new section of root system with soil root. It should be noted that, in this embodiment, the bactericide includes 400-500 times of 50% thiophanate methyl, and the rooting agent includes 0.03-0.05% of naphthylacetic acid.
(5) And embedding the easily degradable double-layer non-woven fabric with the width larger than the depth of the lower cutting groove into the annular groove, and then embedding the panel between the double-layer non-woven fabric. In this step, the width of the nonwoven fabric is 3 times the depth of the lower groove, so that the root with soil is tightly tied by using the nonwoven fabric during seedling raising. The panel mainly plays a role in fixing, and the manufacturing materials of the panel comprise light wood blocks and plastics.
(6) And (4) hooping the periphery of the non-woven fabric embedded with the paneling with two circles of iron wires to obtain the paneling non-woven fabric.
(7) Mixing the native soil and clay according to a ratio of 2-3:2 to form mixed soil, pouring the mixed soil into cavities between the panel non-woven fabric and the roots with the soil layer by layer, and pouring rice water lime water until the soil is wet every 15-20cm thick. The step-by-step splashing of the rice water lime water is beneficial to fully soaking the mixed soil by the rice water lime water so as to play a full bonding role. In the present embodiment, the raw materials of the rice water lime water include saturated lime water and rice water in a mass ratio of 0.1-0.2: 1.
It should be noted that the traditional three-in-one soil is used as a building material, and the sand and stones are adhered together by soil and lime, so that the shatter prevention capacity is improved, and the hardness is increased. The general ingredients of the soil mixture are as follows: clay, slaked lime and sand. For thousands of years, glutinous rice, lime and silt are also added as a three-in-one soil, which is also called glutinous rice mortar. The glutinous rice mortar can be used for treating carbon dioxide (CO) in air2) Gradually into calcium carbonate (CaCO) with a very high hardness3)。
The function principle of the sticky rice mortar is as follows: in the process of making the sticky rice mortar, the following chemical changes occur to lime:
CaO+H2O＝Ca(OH)2(1)；
Ca(OH)2→Ca2++2OH-(2)；
reaction (1) is a slaking reaction of quicklime and water to produce slaked lime, i.e. Ca (OH)2And simultaneously, a large amount of heat is released, and researches show that the quicklime digestion process can generate active oxygen which has strong killing effect on bacteria. Reaction (2) is Ca (OH)2The ionization reaction of (1). This reaction produces two ions: ca2+And OH-. Research has proved that strong alkaline environment can inhibit and kill bacteria, and the action mechanism is that strong alkali can erode bacteriaCell membrane, Ca (OH)2The pH value of the saturated solution is about 12.4, and almost no bacteria can survive in the strong alkaline environment. During the curing process of the sticky rice mortar, the slaked lime undergoes the following chemical changes:
Ca(OH)2+CO2＝CaCO3+H2O (3)；
in this reaction, slaked lime Ca (OH)2And CO in air2CaCO reacted to form calcite crystal form3As the reaction (3) proceeds, more calcium carbonate is produced, and the glutinous rice mortar is gradually solidified and has higher strength.
The research on the biomineralization protective material of the stone cultural relic in the cultural relic protective material laboratory of Zhejiang university discovers that: after 3% of glutinous rice pulp is added into lime, the compressive strength is improved by 30 times, the surface hardness is improved by 2.5 times, and the water immersion resistance is more than 68 days. Glutinous rice pulp and produced CaCO3Have synergistic effect. The university of Zhejiang discovered, after sampling mortar and analyzing simulated mortar, that in the cured glutinous rice mortar, the components of the glutinous rice pulp and CaCO3The adhesive mortar is uniformly distributed, and the adhesive mortar is mutually wrapped and densely filled to form an organic/inorganic synergistic composite structure, so that the adhesive mortar has better toughness and strength.
In this example, based on the above-mentioned findings, the inventors have creatively found that, in the application of plant transplantation, a slaked lime solution is used, since the slaked lime solution contains Ca (OH)2Using Ca2+The loose soil grains are adhered by the coagulation effect on the glutinous grains and the colloid in the rice water; when the amount of the hydrated lime is reasonably controlled, the soil carried by roots is prevented from being hardened and tough, so that the roots are limited from absorbing water and fertilizer and growing, and even the trees die. The inventor just applies the improved rice water mortar to root soil fixation, and not only can ensure that the root system of the tree carries soil to form certain firmness, but also can not disperse during tree lifting and carrying and can not influence the extension and absorption of the root system.
It should be noted that, in this embodiment, the pH of the lime water is adjusted to 5.6-6.5 by using a pH adjusting agent before use, so as to be suitable for the plant adaptation range. Further, the pH value regulator is dilute sulfuric acid.
(8) Tamping the mixed soil when the adding amount of the mixed soil is half, then adding the mixed soil to be tamped again when the mixed soil is 19-21cm away from the ground, and then scattering the rest mixed soil to be even and level ground. The tamping operation is beneficial to the rice water lime water to fully infiltrate the mixed soil.
(9) And digging the peripheral soil of the non-woven fabric of the panel, and sawing the bottom of the root part with the soil and the subsoil. (10) And (4) hoisting the trees by using a tree hoist until the bottoms of the roots with soil leave the ground, and spraying a bactericide and a rooting agent to the bottoms of the roots with soil. (11) The bottom of the root with the soil is wrapped and sewed by the non-woven fabric at the lower part of the panel non-woven fabric, and the non-woven fabric at the upper part of the panel non-woven fabric is drawn to the base part of the tree stem of the tree and fixed. (12) The bottom with the soil root is placed on the ground, the paneling is taken out, and the non-woven fabric is wrapped and fastened by the degradable straw rope. (13) And (4) transporting the trees to a planting place for planting, and performing water slurry and sun protection management.
The features and properties of the present invention are described in further detail below with reference to examples.
Example 1
The embodiment provides a double-layer soil stabilization transplanting method for a coarse sandy soil tree, which comprises the following steps:
(1) transplanting the leaf-cultivated Machilus thunbergii with the diameter at breast height of 9cm in coarse sand soil. The maximum diameter of the root with soil (root soil oblate spheroid) which needs to be dug up finally is determined to be 63cm, the surface layer soil for planting the frames is shoveled and removed to expose new soil, and then an annular groove with the width of 20cm multiplied by 20cm is dug towards the outer edge of the root with soil.
(2) And (4) pouring rice water from the base of the tree to the soil layer immersed in the root with soil.
(3) And (3) after the surface soil at the root part of the carried soil is dried, sawing the peripheral soil at the root part of the carried soil downwards by the annular trench to obtain a lower cutting trench, and mixing the peripheral soil with the soil dug in the step (1) to be used as native soil and placing the native soil on the ground. If the root with the soil of the sawed peripheral soil still collapses, the rice water is poured to the base of the tree towards the inner side of the annular groove while the root with the soil is cut down, and the cut soil is used as the native soil and placed on the ground.
