1. Collection, preparation and storage of soil samples from soil
The collection of soil samples is an important part of determining whether the analysis results correctly reflect soil characteristics. Therefore, it is necessary to choose to collect appropriate soil samples at representative locations. For different analytical purposes, the method of collecting samples is different. Here, only the collection method of mixed samples of cultivated soil is introduced. In order to study the nutrient supply in the tillage layer, it is only necessary to take the soil of about 0-20 cm of the cultivated layer. For the soil with deep roots such as wheat, the sampling depth can be appropriately increased. The sampling point can be determined according to the land area. The smaller area is usually more than 5 points. The larger area (such as 10 mu or more) can be collected more than 20 points. The distribution of sampling points is snake. Shape or diagonal, after mixing, multi-point soil samples are mixed together, and finally about 250 grams is retained as a soil sample for testing.

(1) Determination of significance:
As an important land resource, the area of ​​saline soil in the world is 954.3 million hectares. The total area of ​​saline soil in China is 99.13 million hectares. In the cultivated land of the agricultural area, not less than 100 million mu of saline soil is still the main reason for the large and medium-sized low-yield. Therefore, the rational use of the potential to improve and develop saline land resources is of paramount importance in the sustainable development of the national economy.

7. Determination of pH in soil
(1) Determination of significance:
Soil pH is one of the important basic properties of soil, and it is an indicator of soil formation and ripening and fertilization process. In the soil, it participates in many chemical reactions that affect many soil properties. Microbial activity, synthesis and decomposition of organic matter, soil nutrient retention, and migration of elements during soil development are all related to soil pH. Various plants have a suitable pH range beyond which growth is hindered. Therefore, the significance of soil pH determination is not limited to understanding the pH of the soil itself, but many other soil properties can be judged or extrapolated based on the pH.

Therefore, the significance of soil pH determination is not limited to understanding the pH of the soil itself, but many other soil properties can be judged or extrapolated based on the pH.
(2) Classification of soil pH grade In soil science, according to the law of soil zonal distribution in China, it is more suitable to divide the pH of soil into five grades in practical application. Strong acidity (pH < 5.0), acidity (pH 5.0 to 6.5), neutral (pH 6.5 to 7.5), basic (pH 7.5 to 8.5), and strong alkaline (pH > 8.5).
(3) Method for determining the pH of soil (Method 1) Visual colorimetry:
Take 3 flat spoons of soil into the soil sample bottle, add tap water to the mark line (20ml), shake for 5 minutes, then filter, take 20 drops of the filtrate into the glass test tube with a plastic pipette, and add 2 drops of PH reagent to the test tube. After shaking, observe the color with the eye and compare it with the color chart in the manual. If the measured result is green, both dark green and light green are neutral, pink is acidic, and blue is alkaline.
(Method 2) Electrode method:
(1) Preparation of standard solution 1PH4.01 standard buffer: The reagent of pH 4.01 was dissolved in distilled water without carbon dioxide, and the volume was adjusted to 250 ml of the volumetric flask to be the pH 4.01 standard buffer.
2PH9.18 standard buffer: The reagent of PH9.18 was dissolved in distilled water without carbon dioxide, and the volume was adjusted to 250 ml of the volumetric flask to be the pH 9.18 standard buffer.
(2) Preparation of soil pH value test solution Weigh 10 g of air-dried soil sample through a 2 mm sieve hole in a soil sample bottle, add 50 ml of carbon dioxide-free distilled water, vigorously stir or shake with a glass rod for 1-2 minutes, Set for 30 minutes and then measure with the instrument.

2: Weigh 1 g of air-dried soil sample (accurate to 0.001 g) through a 0.5 mm aperture into another clean beaker, and then add 3 ml of distilled water to fully shake the soil sample.
3: Pipette 2 ml of soil organic matter standard solution into another clean small beaker and add 1 ml of distilled water to a content of 10 mg.
4: Add 10 ml of potassium dichromate solution and 10 ml of concentrated sulfuric acid to each of the above small beakers, shake continuously, park for 20 minutes, then add 10 ml of distilled water, shake well, and then settle the sediment (Note: Conditional The user can centrifuge the mixture in a small beaker with soil samples.
5: Pipette each solution in the above small beakers (small beakers with soil samples to be clarified) to 10 ml each, put them into a 50 ml volumetric flask, dilute to the mark with distilled water, and shake well.
6: Colorimetric determination of the instrument: For details, please refer to the method of using the instrument in the instruction manual.
(2) Calculation of results:
Soil organic matter content is expressed as a percentage, retaining two decimal places.
Soil organic matter (%) = [(C × 1.724) / (m × 10 )] × 100 × 1.32
=(C/m)×0.23
Where: C——the content of the liquid to be tested m——the quality of the soil (1 g)
Reagent preparation method:
Concentrated sulfuric acid: 98% (analytical grade)
Potassium dichromate solution: Weigh 39.23 g of potassium dichromate (analytical grade), dissolve it in 600 ml of water, dissolve it, and dilute to 1 liter with distilled water.
0.5%-C standard solution: Weigh 1.376 g of glucose (chemically pure) in a 100 ml volumetric flask, add distilled water to dissolve, add 1 ml of concentrated sulfuric acid, add water to volume, shake well, the standard solution contains 5 mg of carbon. /ml.

If you have neck pain or pain in your arm coming from your neck, your doctor may refer you to a physical therapist (PT) to help treat your condition. Neck pain can limit your ability to turn your head, look up or down, or perform normal activities like sleeping or exercising.
Symptoms that often come from your neck include:
Pain in the middle of your neck
Pain in one side of your neck
Pain in one or both of your shoulder blades
Occasionally, pain or numbness and tingling in your arm or hand
Since many different symptoms coming from your neck can be felt in many different places, it's important to see your doctor or physical therapist to help determine the cause of your symptoms and to decide on the best way to manage your condition.
If you visit a physical therapist to help treat your painful neck condition, he or she will likely perform an initial assessment and then prescribe various treatments. One such treatment is cervical traction.
