Description
Technical Field
The invention belongs to the technical field of land utilization research, and particularly relates to a leakage-proof quick construction method for changing a dry land into a paddy field.
Background
The yield reduction caused by drought is one of the main obstacles of grain production in arid and semiarid regions, China is a country with serious water shortage, and the soil area of China is more than 60 percent of that of arid, semiarid and semihumid climatic regions, wherein the area of the arid regions is more than 5 hundred million mu.
At present, the method for changing the dry land into the paddy field mainly comprises the steps of plough layer soil stripping, field block shaping, field ridge building, field seepage prevention, plough layer soil reclamation, leveling and water storage maintenance. For the dry modified paddy field, an anti-leakage plough bottom layer is not formed yet, the water leakage amount is large, the water retention rate of the newly modified paddy field in the first year is always low (generally only 35-50%), and a large amount of available nutrients are lost. In order to solve the technical problems, the Chinese patent with application number CN201910707398.5 discloses a method for changing dry land into paddy field in a mountain yellow soil area, which comprises the following steps: determining the field block range to be modified, stripping surface soil, leveling a base, building a field ridge, backfilling the surface soil and leveling a field surface; soaking in water and pulping; the rice transplanting cultivation is to transplant rice and daily manage and protect the field according to the traditional mode. By combining modern farming and traditional farming technologies, the method can quickly leak the cracks, promote the water storage of the newly-built paddy field, solve the problem of slow water storage of the traditional dry-land water-changing method, promote the newly-built paddy field to form a high-quality plough bottom layer, facilitate the forward succession of the newly-built paddy field, remove the root system of weeds in the field, flatten the field surface and facilitate the later management of rice planting; more importantly, the method can overcome the soil blocking of the newly-built paddy field and effectively prevent the occurrence of the rice runt seedlings. However, the method can not rapidly build the anti-leakage plough bottom layer for improving the drought into the paddy field, and the time for building the anti-leakage plough bottom layer is long.
In order to solve the above technical problems, it is necessary to research and develop a rapid construction method for preventing leakage of dry land into paddy field, so as to speed up the construction of a leakage-proof plough layer for dry land into paddy field, thereby solving the problem of water leakage of dry land into paddy field.
Disclosure of Invention
The invention aims to solve the technical problems and provides a rapid construction method for preventing leakage of a dry land-to-paddy field.
In order to solve the above problems, the technical scheme provided by the invention is as follows:
the invention provides an anti-leakage rapid construction method for changing dry land into paddy field, which comprises the following steps:
(1) excavating the surface soil of the dry land to a bottom soil layer, and excavating the soil for later use;
(2) leveling, rolling and tamping a bottom soil layer, backfilling the soil in the step (1) on the bottom soil layer, irrigating, and turning over to break the soil;
(3) applying a conditioner into the smashed soil, irrigating and steeping the field after 2-3 days, carrying out rotary tillage, and starting soil preparation and fertilization.
From the soil generation level, the soil generation level of the dry land is divided into a cultivation layer, a core soil layer, a bottom soil layer and a basal rock layer from top to bottom, the core soil layer is mainly arranged below the cultivation layer, the thickness is small, and the soil gravity water leakage is fast, so that in order to quickly construct the anti-leakage plough bottom layer of the dry-land-to-paddy field and solve the water leakage problem of the dry-land-to-paddy field, the bottom soil layer needs to be subjected to leakage stoppage treatment.
In order to disperse and dissolve silica, alumina or clay minerals existing in the soil in a large amount to form colloids, the colloids flow downwards along with the leaked water and then are condensed in the capillary channels of the water leakage on the substrate layer to block the capillary channels of the water leakage in the substrate layer, preferably, in the step (3) of the invention, the conditioner is: urea.
In order to obtain better plugging effect, preferably, in the step (3) of the invention, the addition amount of the conditioning agent is 75-125kg/667m23-5 times of the common fertilizing amount
The ridges play a certain role in the water retention function of the paddy field, and in order to obtain a better water retention effect, preferably, in the step (2), the ridge is designed to be higher than the surface of the paddy field by 15-20 cm after soil is backfilled.
The field water holding capacity is a basic characteristic of soil water holding, and for ensuring the field water holding characteristic of a newly added paddy field, seepage prevention is needed to be carried out, and a plough bottom layer is constructed. The plough bottom layer is a hard soil layer formed under the plough layer during cultivation, namely a bottom soil layer, and has a water retention effect by generating a barrier effect on water infiltration. In order to obtain a better water retention effect, preferably, in the step (2) of the invention, the thickness of the substrate layer is not less than 10cm, and if the thickness is less than 10cm, the substrate layer is rolled and tamped after the additional soil is taken for supplement.
In order to better precipitate the slurry and block a larger water leakage channel in the substrate layer, preferably, in the step (2) of the invention, the irrigation is repeated for 3-5 times, and the soil is broken up by ploughing.
The rice is a water-loving crop, but the rice is drowned by excessive water, and in order to ensure the normal growth of the rice crop, the height difference of the field surface is preferably controlled to be 0-3cm after soil preparation in the step (3) of the invention.
In the step (2), during the construction of dry land to water, the engineering machinery is used for rolling and tamping the substrate layer to block a larger water leakage channel in the substrate layer.
In the step (2), soil is backfilled on a compacted bottom soil layer for irrigation, and the soil is smashed by a rotary cultivator under the state of soaking water, so that fine soil particles flow downwards, and small water leakage passages in the bottom soil are blocked.
In the step (3), a soil conditioner is applied to the backfilled soil, the soil conditioner is fully mixed with the soil in a water soaking state, aluminum oxide or clay minerals in the soil are dispersed and dissolved to form colloids, the colloids flow downwards along with the leakage water and then are condensed in the capillary channels of the leakage water on the bottom soil layer, and the capillary channels of the leakage water in the bottom soil layer are blocked.
The main component of the soil-exchange acid is Al3+，Al3+Can be combined with negative charges on the surfaces of hematite, allophane or kaolinite particles in soil to bond the soil particles together. Al (Al)3+Neutralization to Al (OH)3This sticking relationship is then broken, helping to disperse the soil particles. In order to promote the particle dispersion of hematite, allophane or kaolinite, the invention discovers that after the dosage of urea is increased by 2-4 times compared with the common fertilizing amount, the urea has the functions of neutralization and soil particle dispersion, the urea can be used as a conditioner, and the urea can generate the following reactions after being applied to soil:
CO(NH2)2+H2O＝NH3↑+CO2↑；
the urea can play two roles after hydrolysis, on one hand, the generated OH-Can further increase the pH value of the soil and neutralize Al in the soil3+The adhesion relationship among the particles such as hematite, allophane or kaolinite in the soil is further broken; on the other hand, NH4 +As monovalent ion, the soil is a good soil particleThe dispersant can promote the soil particles to disperse after combining with negative charges on the surfaces of particles such as hematite, allophane or kaolinite, promote the soil particles to dissolve into colloid or disperse into fine particles, can flow downwards along with the water flow in the soil, and is condensed or deposited in fine water leakage gaps in the plough bottom layer, thereby blocking fine soil water leakage channels.
The nitrogen provided by the urea to the soil can be absorbed by rice plants in the next season, so that no nitrogen fertilizer is needed to be applied when the rice is planted in the next season, and the fertilization cost of the rice is reduced. In addition, when the urea is applied, a part of nitrogen can be lost in a mode of ammonia volatilization, and the nitrogen lost by ammonia volatilization can return to the ground in a rainfall mode, so that the nitrogen is provided for plants which cannot be fertilized, such as forests, and the like, the growth of the forests is promoted, and the environment benefit is good.
Compared with the prior art, the invention has the beneficial effects that:
1. the invention combines a physical method with a chemical method, blocks a larger water leakage channel by the physical method, blocks a capillary channel by the chemical method of the urea conditioner, and improves the seepage-proofing and water-retaining capability of the dry-land rice field, thereby effectively solving the water leakage problem of the dry-land rice field.
2. The method has simple steps, convenient operation and simple and easily controlled conditioner, and the added conditioner is urea, so that the seepage-proofing and water-retaining capacity of the dry-land-to-paddy field can be improved, the nitrogen content of the soil can be improved, and the rice planted in the first year after transformation does not need to be fertilized with nitrogen.

The leakage strength of the paddy fields treated in examples 1 to 3 and comparative examples 1 to 3 was measured in the same manner as described above, and the results are shown in Table 1.
TABLE 1 leakage Strength of differently treated Rice fields
As can be seen from Table 1, the leakage strength of comparative example 1 and comparative example 2 is much greater than that of examples 1-3, which shows that the addition amount of urea of the present invention has a great influence on the leakage strength of paddy field, while too small addition amount of urea has poor dispersion effect, which is not good for promoting the dispersion of soil particles, thereby promoting the dissolution into colloid or the dispersion into fine particles, which cannot well block the fine soil leakage channel of the bottom soil layer, if too much urea addition amount is added, a large amount of ammonia gas is generated, which affects the dispersion effect, and holes are also generated, which cannot well block the fine soil leakage channel of the bottom soil layer. In addition, the urea applied in the comparative example 3 can not well block the soil water leakage channel with small bottom soil layer, and the water leakage of the rice field is serious. The invention further discloses a method for improving the seepage-proofing and water-retaining capacity of the dry-land rice field by combining a physical method with a chemical method, blocking a larger water leakage channel by the physical method and blocking a capillary channel by the chemical method of a urea conditioner, and effectively solving the water leakage problem of the dry-land rice field.
