Abstract:The physical and chemical properties of pear orchard soil is the basis of scientific fertilization, rational nutrient management and soil improvement of pear trees. The soil of five integrated test station in the Yellow River basin of the national pear industry technology system was selected, 0-20 cm mixed soil samples under the tree canopy drip line were collected for soil physical and chemical characteristics analysis. The results showed that the other pear orchard soil pH in the the Yellow River basin was between 6.62 and 7.82 Tai'an Test Station. More than 90% of the pear orchard organic matter content was less than 20g/kg, of which 24% of the pear soil organic matter content less than 10g/kg, which belonged to the lack of state.The Yellow River basin were only 9% pear orchard organic matter content of the region exceed 20g/kg, and almost all pear orchards soil nitrogen content was lower than 100mg/kg, and the overall was low. Soil available phosphorus and available potassium enrichment were obvious,among them, the soil available phosphorus and available potassium content were higher than 40mg/kg and 200mg/kg in Yangling Experimental Station, respectively, which were 87% and 94% respectively.The main pear orchard in the area soil exchangeable calcium and magnesium contents were all higher. the average values were as high as 3073mg/kg and 220mg/kg, respectively. 75% of pear soil available iron content was lower than 10mg/kg.About 50% of pear soil available manganese content is less than that of 10mg/kg,about 30% of pear soil available copper and zinc content was lower than 1mg/kg, the lack or lower proportion were higher. Except for the low effective boron content of some pear orchards in Taigu, Zhengzhou and Tai'an, nearly 60% of the effective boron content of pear orchards was suitable and abundant. In this paper, the content of soil organic matter in the main pear of the Yellow River basin was low, the available phosphorus and potassium are enriched and the content of soil trace elements was low. According to the above characteristics of nutrient content and the nutrient content of tree, some suggestions on nutrient management of pear garden in the Yellow River basin are proposed.
