Embodiment 1
[0039] Measurement:
[0040] Planting area 667m 2 , yellow-brown soil. The total mercury, total lead, 0.0004 mg / L, and 0.0036 mg / L of heavy metals in water measured by ultraviolet-visible spectrophotometry are 0.0003 mg / L, 0.0004 mg / L, and 0.0036 mg / L of total arsenic; the selenium content in water measured by fluorescence spectrophotometry is The selenium content in the air was 0.32 μg / L, and the selenium content in the air was 5.3 μg / L; the heavy metals in the soil were 0.28 mg / kg cadmium, 200 mg / kg lead, 0.28 mg / kg mercury, and 26 mg / kg arsenic in the soil by anodic stripping voltammetry. The effective soil layer is 40cm, the organic matter is 14.6g / kg, the total nitrogen is 0.99g / kg, the available nitrogen is 90mg / kg, the available potassium is 235mg / kg, the available magnesium is 40mg / kg, the available phosphorus is 10.2mg / kg, and the available zinc is 4mg / kg. Selenium 0.328mg / kg, effective selenium 0.02mg / kg, pH value 5.38.

[0060] Measurement:
[0061] Planting area 667m 2 , Silt sandy soil. The total mercury, total lead, 0.0024 mg / L, and 0.0046 mg / L of heavy metals in water measured by UV-visible spectrophotometry were 0.00013 mg / L, 0.083 mg / L total lead, and 0.0046 mg / L total arsenic; The selenium content in the air is 0.3μg / L, and the selenium content in the air is 5.8μg / L; the heavy metal cadmium in the soil is 0.37mg / kg, lead 260mg / kg, mercury 0.40mg / kg, and arsenic 30mg / kg measured by anodic stripping voltammetry. The effective soil layer is 42cm, the organic matter is 18.3g / kg, the total nitrogen is 0.96g / kg, the available nitrogen is 90mg / kg, the available potassium is 281.6mg / kg, the available magnesium is 47mg / kg, the available phosphorus is 18mg / kg, and the available zinc is 1mg / kg. Selenium 0.1mg / kg, effective selenium 0.001mg / kg, pH value 4.98.

[0081] Measurement:
[0082] Planting area 667m 2 , yellow-brown soil. The total mercury, total lead, 0.0004 mg / L, and total arsenic were 0.0004 mg / L, 0.0038 mg / L, and 0.0038 mg / L of heavy metals in water measured by ultraviolet-visible spectrophotometry; The selenium content in the water was 0.32 μg / L, and the selenium content in the air was 2.3 μg / L; the heavy metal cadmium in the soil was 0.23 mg / kg, lead 300 mg / kg, mercury 0.4 mg / kg, Arsenic 30mg / kg. Effective soil layer 35cm, organic matter 15.3g / kg, total nitrogen 0.8g / kg, available nitrogen 80mg / kg, available potassium 70mg / kg, available magnesium 45mg / kg, available phosphorus 12mg / kg, available zinc 0.8 mg / kg, total selenium 0.927mg / kg, effective selenium 0.008mg / kg, PH value 8.
[0083] analyze:
[0084] (1) There are more available potassium in the soil (the minimum is 80mg / kg), low available zinc (the minimum should be 1-5mg / kg), low available selenium (the minimum should be 0.993mg / kg), and the pH value is suita...
