The soil texture is also the soil type divided according to the particle composition of the soil, mainly inherits the type and the characteristics of the matrix of the finished soil, is influenced by artificial factors such as farming, fertilizing, irrigation and drainage, land leveling and the like, is a very stable natural attribute of the soil, and has great influence on the soil fertility.
The sandy soil has good permeability, is easy to cultivate and fast in temperature rise, but the sandy soil has weak drought resistance and is easy to leak water and fertilizer, so that the soil has less nutrients, and in addition, the sandy soil lacks of clay grains and organic matters, so that the fertilizer retention performance is weak, and the quick-acting fertilizer is easy to lose along with rainwater and irrigation water. Therefore, the organic fertilizer is applied to sandy soil forcibly, topdressing is carried out timely, and the principle of frequent watering and thin application is mastered.
The clay soil has rich nutrients and high organic matter content, so most soil nutrients are not easy to be lost by rain and irrigation water, and the fertilizer retention performance is good. However, the clay has poor permeability and is difficult to cultivate, and when the soil is in rain or irrigated, water is difficult to seep in the soil body, so that the water is difficult to drain, the growth of crop root systems is influenced, and the absorption of the root systems to soil nutrients is hindered. For the soil, the ditching and the drainage are paid attention to the production, the underground water level is reduced to avoid or reduce waterlogging, and the fine cultivation is selected under the condition of proper soil moisture, so that the soil structure and the soil tilth are improved, and the release of soil nutrients is promoted.
The soil is not sticky and sand-free, has the advantages of sandy soil and clay, is ideal soil, has excellent ploughability and is suitable for various crops.
According to the physical conditions of different soils, different improvement operations can be made. The yield of most crops in agricultural production can be increased by improving the physical conditions of the soil, the dynamic change conditions of the temperature and the moisture of the soil can reflect the texture, the structural condition, the porosity and the like of the soil, and then the change conditions of the physical conditions of the soil can be analyzed. According to the change condition of the physical condition of the soil, the user can be reminded in time whether to irrigate, turn over, loosen and improve the soil. And then the planting condition is timely and effectively improved.
The existing manual monitoring method depends on the experience of agricultural experts and growers, has high requirements on experts and labor personnel, and can cause errors due to misjudgment and errors, thereby bringing about insufficient further fertility of the soil.
And laboratory analysis spends the time cycle long, is unfavorable for in time judging the soil state to consume the manual work many, the professional demand is big, the process is complicated, soil fertility physical condition can not in time be improved.
In order to improve the accuracy and efficiency of soil detection, the embodiment of the invention provides a soil monitoring method, and the soil monitoring method provided by the embodiment of the invention is first described in detail below.
Fig. 1 is a schematic flow chart of a user soil monitoring method according to an embodiment of the present invention. As shown in fig. 1, the execution subject of the method is a server, and the method may include S101-S103, which are specifically as follows:
s101, obtaining a plurality of first physical parameter values obtained by a plurality of soil collection points collected by a soil physical parameter sensor in a first time period; the plurality of soil collection points are soil collection points of the same target soil.
The plurality of soil collection points are a plurality of soil collection points with the same depth, or the plurality of soil collection points are a plurality of soil collection points with different depths.
In one embodiment, the soil collection points at the same depth are multiple sampling points deployed in the horizontal direction, and the data collected by the sampling points can be averaged by deploying the sampling points in the horizontal direction, so that the stability and the referential performance of data collection can be improved. For example, on 100 square meters of soil, one sampling point is deployed every 10 square meters, i.e., there are 10 sampling points in total. And averaging the data acquired by the 10 sampling points at the same time point to obtain the soil physical parameter value of the time point.
In one embodiment, the multiple soil collection points with different depths are multiple sampling points deployed in the profile direction, and the multiple sampling points deployed in the profile direction can perform fitting processing on data collected by the sampling points, so that the rule that the physical parameter value changes along with the increase of the depth is determined.
The factors of the change of the soil temperature are many, such as the structure, texture, tightness, porosity, water content of the soil affect the heat capacity and heat conductivity of the soil and the heat consumed by the water evaporation of the soil. The change of the physical conditions of the soil can be reflected by the temperature and the humidity of the soil.
The soil temperature and humidity change trends of different depths are basically consistent, the soil temperature and humidity change trend is changed periodically along with the time, the temperature is gradually reduced along with the increase of the soil depth, the image trend is that the amplitude of temperature waves is gradually reduced, the change amplitude of the water content is also gradually reduced, and the delay time is gradually increased. That is, it is assumed that the change rule of the physical parameter value of the soil collected at a depth of 20cm along with time is first depth soil change information, and the fluctuation amplitude of the physical parameter value of the soil at the first depth along with time is a first depth amplitude; and on the basis that the change rule of the physical parameter value of the soil collected at the depth of 40cm along with the time is the change information of the soil at the second depth, and the fluctuation amplitude of the physical parameter value of the soil at the second depth along with the time is the second depth amplitude. The second depth magnitude should be less than the first depth magnitude and the second depth magnitude should occur at a time later than the first depth magnitude.
In one embodiment, soil temperature and humidity sensors are deployed on the horizontal plane and the profile, and it is understood that the soil temperature and humidity sensors can measure the temperature and humidity of the soil simultaneously. The soil physical parameter sensor can simultaneously measure a plurality of physical parameter values of soil.
The soil humidity sensor is a sensor for measuring soil moisture with high precision and high sensitivity. By measuring the dielectric constant of the soil, the real moisture content of various soils can be directly and stably reflected. The soil moisture sensor can measure the volume percentage of soil moisture, and is a soil moisture measuring method which meets the current international standard. The soil temperature sensor can monitor the soil temperature and is used for experiments and scientific researches.
The soil temperature and humidity sensor, the soil temperature sensor and the soil physical parameter sensor all adopt buried measuring methods.
In one embodiment, fig. 2 is a schematic cross-sectional view of soil provided by an embodiment of the invention. As shown in fig. 2, a pit with a diameter of more than 60cm is dug in the vertical soil horizontal plane, the depth is determined according to the requirements of the actual measurement process, then the sensor steel needle is horizontally inserted into the pit wall at the depths of 20cm, 40cm and 60cm respectively, the pit is filled with soil, and the soil in the pit is compacted to ensure that the sensor steel needle is in close contact with the soil. After a period of stabilization, measurements and recordings can be made for several days, months or even longer. The soil temperature and humidity sensor can continuously monitor the soil temperature, and has stable performance, high reliability and no maintenance.

Determining first variation information of a plurality of first physical parameter values in a first time period, comprising: determining first physical characteristic parameter values corresponding to the plurality of first physical parameter values respectively; first variation information is determined based on the plurality of first physical characteristic parameter values.
As shown in fig. 3, fig. 3 is a schematic diagram of variation information provided by an embodiment of the present invention. When the plurality of soil collection points are a plurality of soil collection points with different depths, on one hand, the first change information can represent the change situation that the physical parameter value of a certain time obtained by a time node with more representative data in a certain time period increases along with the soil depth. For example, the variation of the physical parameter value collected at 18 th day within 30 days along with the soil parameter is taken as first variation information; on the other hand, the first variation information may also indicate a variation of the average value of the collected physical parameter values with the soil depth increase in a certain time period, for example, the physical parameter values collected within seven days of the week are averaged, and a variation of the average value of the physical parameter values with the soil depth increase in seven days is taken as the first variation information. It will be appreciated that the time nodes at which the values of the physical parameters are collected are substantially consistent over the seven days. The data acquisition condition of the second change information is consistent with the first change information.
Fig. 4 is a schematic diagram illustrating variation information according to an embodiment of the present invention, and as shown in fig. 4, when a plurality of soil collection points are a plurality of soil collection points at the same depth, first variation information indicates that a physical parameter value varies with time within a certain time period; the second variation information indicates a case where the value of the physical parameter varies with time within a certain historical time period. It is understood that the time period may be hours, days, weeks or months, with the second variation information occurring before the first variation information.

In one embodiment, as shown in fig. 3, it is assumed that the first variation information is measured on day 300 after the start of monitoring and the second variation information is measured on day 30 after the start of monitoring.
