Technical Field
The invention relates to the technical field of municipal engineering, in particular to a soil improvement method for improving the survival rate of municipal pot planting.
Background
At present, many greenery on municipal roads is formed by potting. Therefore, the pot culture has very high utilization rate in municipal garden engineering. In addition, each region is affected by the local geographical environment and climate due to the difference of the regions, resulting in all the changes of soil components and greatly reduced survival rate of plants. For example: coastal cities near the seaside have particularly high salt content of groundwater due to the proximity to the seaside. In high-temperature summer, water in the soil is evaporated, and salt content in a bottom soil layer and underground water is accumulated on a surface layer along with the rising of capillary water in the soil, so that the salt content of the surface soil is gradually accumulated, and the salinization of the soil is caused. The salinization of soil is one of the types of soil degradation, and due to the fact that saline-alkali soil contains saline-alkali components such as chlorides, sulfates and bicarbonates of potassium, sodium, calcium and magnesium, the physicochemical property of the soil is abnormal, the soil quality is low, plant growth is inhibited to different degrees, and the survival rate of plants is very low.
The salinization of the seaside urban soil is very serious, the improvement of large-area soil in the city is difficult, and the method is high in cost and difficulty and even cannot be realized. Therefore, the use of the pot culture is indispensable, the salt in the groundwater can be well cut off from rising to the soil in the pot culture, and the soil in the pot culture can not be ensured

Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The invention provides a soil improvement method for improving the survival rate of municipal pot planting, which comprises the following steps:
s1, selecting soil, namely selecting the soil with the depth of 0-20cm from the earth surface of the saline-alkali soil, so that the content of the chloride, sulfate, bicarbonate and other saline-alkali components of potassium, sodium, calcium and magnesium in the selected soil is relatively low, thereby reducing the difficulty of improving the saline-alkali soil and improving the efficiency of improving the saline-alkali soil;
s2, sterilizing, namely putting the selected soil into an alcohol solution, standing for 0.5-2 hours, and sterilizing to avoid the bacteria existing in the soil from decomposing the modifier added later, thereby influencing the modifying effect of the modifier;
s3, adding water for leaching, putting the sterilized soil into a leakage device, continuously adding water into the leakage device until water overflows from the bottom of the leakage device, stopping adding water for standing for 15-45 minutes, continuously adding water with the same volume, and repeating the operation for 6-8 times; so operate for when the appearance water yield of soil is saturated, water can stay in soil, thereby dissolve saline and alkaline ion and remaining alcohol, and then add water again, make oozing under water in the soil, and bring out saline and alkaline ion, continue to dissolve saline and alkaline ion in the water entering soil that newly goes into.
Experiments show that saline-alkali soil can be effectively improved by a leaching mode, and the pH value can be reduced by 1.2-1.75 generally.
S4, adding a modifier, and uniformly mixing the modifier into the soil, so that the pH value can be effectively reduced, the water permeability and the air permeability of the soil can be improved, the soil viscosity is reduced, and the nutrient content required by soil planting can be increased;
s5, adding microorganisms, and culturing for 2-5 days, so that residual saline-alkali ions can be effectively decomposed, the saline-alkali environment is improved, the fertility and the activity of soil can be recovered, and the growth of plants is promoted;
s6, filling the soil into a pot culture pot.
Among the above-mentioned technical scheme, the technical principle is reasonable to it is very convenient to operate, and in addition, improvement effect is good, and improvement efficiency is high.
It is understood that the leakage device described in step S3 is a barrel structure, and the bottom of the leakage device is provided with a plurality of water outlet holes.
Specifically, the alcohol concentration used for sterilization in step S2 is 75% to 85%. In the conventional sterilization, the concentration of the used alcohol is generally 75%, and the alcohol can play a good sterilization effect. In this embodiment, the concentration of the alcohol solution is greater than 75%, and the soil is sterilized comprehensively instead of the surface of the soil, but the alcohol has strong volatility, and the infiltration rate of the alcohol in the soil is slow, so that the alcohol concentration needs to be increased, the volatilization of the alcohol is prolonged as much as possible, and a thorough sterilization effect is achieved.
Further, in the step S2, the selected soil is put into an alcohol solution, and is left to stand for 0.5 to 1 hour in an environment with a temperature not exceeding 15 ℃, which is a sterilization stage, so that the temperature needs to be reduced to slow down the volatilization rate of the alcohol, and then is left to stand for 1 to 2 hours in an environment with a temperature of 20 ℃ to 30 ℃, which is a volatilization stage, and the alcohol in the soil can be completely recovered by a sufficient time, so as to avoid affecting microorganisms added later.
It will be appreciated that during the sterilization phase, a vacuum environment may be provided to provide a desirable sterilization environment for the alcohol. In the volatilization stage, the alcohol is exposed in the air once, so that the volatilization rate of the alcohol is accelerated, and the complete volatilization of the alcohol is ensured.
According to the further arrangement of the invention, the modifying agent in the step S4 is formed by mixing one or more of lignite, turf and weathered coal. As can be understood, the conditioner belongs to humic acid, and the conditioner serving as the conditioner of the saline-alkali soil not only can effectively reduce the pH value, but also can increase the organic matter content of the saline-alkali soil because the conditioner contains a large amount of organic matters.
By repeating the experiment of 4 groups, the pH values of the 4 groups are respectively reduced by 0.26%, 0.83%, 1.08% and 1.57% by increasing the modifier, and the sodium ion contents are respectively reduced by 82.4%, 92.6%, 89.1% and 78.9%.
Specifically, in the step S4, 30 to 80 g of the improver is added to each kilogram of soil.
According to a further configuration of the present invention, the microorganism added in step S5 is one or more of phosphate solubilizing bacteria, sulfur oxidizing bacteria, mycorrhizal fungi, silicate bacteria, and bacillus. In the step S5, the number of microorganisms added per gram of soil is not less than 10 hundred million.
According to the technical scheme, the microorganisms are inoculated, so that the decomposition of organic matters can be facilitated to form new humus, various organic acids are generated, the saline-alkali soil is further improved, the pore size can be increased, the firmness is reduced, the activity of the soil is increased, the fertility of the soil is increased, and the growth of plants can be promoted better.
It can be understood that, since the soil is sterilized, the soil contains fewer strains, and therefore, in order to ensure the normal growth of the plants, other conventional strains need to be inoculated in the soil, nutrients are released, rich carbon and nitrogen sources are provided for the plants, the fertility of the soil is improved, for example, nitrogen in the atmosphere can be reduced to ammonia nitrogen, nitrogen fixing microorganisms for the plants to absorb and utilize, and the like.
The embodiments of the present invention have been described in detail, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments, including the components, without departing from the principles and spirit of the invention, and still fall within the scope of the invention.
