Description
Technical Field
The invention belongs to the technical field of agriculture, and particularly relates to a soil sample collection method.
Background
The soil fertility distribution condition is a key element in an agricultural production environment, and at present, in order to obtain the soil fertility condition, a measure is usually taken to sample and analyze the soil fertility condition, namely, the soil in a farmland is subjected to intensive sampling to determine the content of nutrient components such as nitrogen, phosphorus, potassium and other soil organic matters.
Soil sampling generally adopts a mixed soil sample, namely, equal amount of soil is collected at multiple points on a sampling land, and the soil is uniformly mixed to obtain the mixed sample. Usually, a plough layer mixed soil sample is directly collected, namely, soil samples of a plurality of sample points are uniformly mixed in equal quantity to form a mixed sample for measurement, and then a fertilization scheme is designed according to the detection result of the mixed soil sample. However, when the sampling plot is large, the situation that the soil fertility of different areas on the same sampling plot is different occurs, the mixed soil sample is obtained by mixing soil samples of different sampling points, the specificity of the soil samples of different areas cannot be reflected, the detection result of the mixed soil sample cannot represent the real situation of the soil of each area, and the situation that the soil of the area A is lack of element X, the soil of the area B is rich of element X, and the element X of the mixed soil sample is in a normal range may exist. Therefore, the method for collecting the mixed soil sample cannot accurately reflect the difference of the soil fertility of different areas on the sampling plot when the area of the sampling plot is large, so that the situation that the difference of the soil fertility of different areas on the sampling plot is obvious, but the plant growth is poor due to the implementation of the same fertilization scheme is caused.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a soil sample collection method which can reflect the soil fertility differences of different areas in a sampling area and provide scientific basis for designing an accurate fertilization scheme.
In order to achieve the purpose, the invention adopts the following technical scheme:
a soil sample collection method specifically comprises the following steps: defining areas with roughly consistent crop varieties and growth conditions as a sampling area, and defining each difference area of inconsistent areas as a sampling area; and determining a plurality of sampling points in each sampling area for respective sampling, wherein the soil samples collected by each sampling point are independently sampled and are not mixed with each other.
Furthermore, in a single sampling area, sampling is carried out on a 200-300 mu farm according to a sampling point of 40-60 mu; and sampling at a sampling point of 200 and 300 mu in a 3000 mu farm of 2000 and 300 mu.
Furthermore, the method for determining the sampling points in the single sampling area is one of a diagonal method, a quincunx method, a checkerboard method and a snake method, and the edges of the field block and the special sample points are avoided.
Furthermore, each sampling point selects a sampling plant, marks longitude and latitude, and collects a soil sample of a fertilizing point of the selected sampling plant and a soil sample between a row of the selected sampling plant and an adjacent plant.
Furthermore, when the soil sample of the fertilizing point is collected, if the fertilizing point is on a dripping line of a plant crown, the soil sample of the fertilizing point is collected; if the fertilizing point is not on the dripping line because the drip irrigation pipe is closer to the trunk of the plant, the soil sample is collected at the dripping position of the drip irrigation pipe, and meanwhile, the soil sample is collected at the dripping position of the crown of the plant.
Furthermore, the collected soil samples are 0-30 cm of plough layer soil, each sample weighs 100-500 g, and impurities are avoided during sampling.
Furthermore, a spade is used for collecting the foundation soil sample, and a soil auger is used for collecting the soil sample in the growth period.
The invention has the beneficial effects that:
1. the invention defines the areas of generally consistent crop variety and growth as a sampling area, and each different area of inconsistent areas as a sampling area. And determining a plurality of sampling points in each sampling area for respective sampling, wherein the soil samples collected by each sampling point are independently formed and not mixed with each other, and then, detecting and analyzing each soil sample. The soil sample collection method can accurately reflect the soil fertility differences of different areas (different sampling points) in the same sampling area, avoids the situation that the soil fertility differences of different areas (different sampling points) in the same sampling area are obvious and cannot be detected by a conventional mixed sampling method, and provides scientific basis for customizing a special formula fertilizer and designing an accurate fertilization scheme.
2. The sampling method is suitable for farms with large plants such as fruit trees, and the like, and each sampling point collects a soil sample of a fertilizing point, a soil sample of a water drip line and a soil sample between rows, so that the soil fertility condition of each sampling point can be accurately mastered, and scientific basis is provided for customizing a special formula fertilizer and designing an accurate fertilizing scheme.
