| Abstract: |
| Application methods and amount of different types of organic fertilizer and the apple yield were surveyed in 56 typical orchards of Weibei areas in Shaanxi Province,and soil organic matter in different layers were analyzed in order to understand the current situation of soil organic matter content.The results showed that the amount of manure applied to the field and organic matter content in soil was positively correlated with apple yields.The average soil organic matter content is 1.26% in 0～40 cm soil layers in apple orchards of Weibei areas,ranged from 0.86% to 2.17%;Organic matter content in 0～40 cm soil layers(1.26%) was obviously higher than in 40～60 cm(0.90%),organic matter contents in different area are different.The vertical difference of soil organic matter content was pointed out in different area,according to the results of experiments,soil organic matter contents index in Shaanxi Province was made out. |
