Classification and Spatial Distribution of Macronutrients and Micronutrients in the Soil of Greenhouse Sweet Cherries

Abstract

To understand the distribution of trace elements in the soil of greenhouse sweet cherry, using soil samples from solar greenhouse sweet cherry orchards in Chifeng, Inner Mongolia as the object, the trace element indicators in the soil of different sweet cherry production areas were analyzed using the "S" shaped 5-point sampling method. Descriptive statistics were conducted. The results showed that in the soil, the average value of CaO is 3.38%, level 2 and relatively abundant, relatively deficient accounting for 4.76%; that of MgO is 0.74%, level 4 and relatively deficient, relatively deficient accounting for 100%; that of total S is 293.24 mg/kg, level 2 and relatively abundant, relatively deficient accounting for 38.1%; that of total Cu is 20.61 mg/kg, level 4 and relatively deficient, relatively deficient accounting for 52.38%; that of total Zn is 62.06 mg/kg, level 3 and moderate, relatively deficient accounting for 52.38%; that of total B is 30.73 mg/kg, level 4 and deficient, relatively deficient accounting for 95.24%; that of total Mo is 0.70 mg/kg, level 2 and abundant, relatively deficient accounting for 38.1%. Although sweet cherries can be cultivated and produced normally in the sunlight greenhouse in Chifeng, the levels of trace elements in the soil are low and the variability is large. Effective measures need to be taken to improve and supplement them. In future production, it is recommended to increase the application of magnesium iron micro fertilizers to meet the demand of large cherries for trace elements.
