英文摘要	There are many different planting methods for crops, however it is very important to improve the distribution ratio of elements in different organs of crops. Therefore, to understand the effect of different planting patterns on crop element balance, we selected Cyperus esculentus continuous cropping (CC) and C. esculentus -wheat rotation cropping (RC). The leaves, tubers, roots, and soil samples were taken at the mowing time (August 1st, on the 81st day after seed sowing; August 24th, on the 105th day after seed sowing; September 16th, on the 128th day after seed sowing). Results showed that CC and RC had significant effects on soil SO42  and Cl-. With the mowing time, the relative abundance of TN (total nitrogen) in tubers showed an increasing trend, the relative richness of TN in roots decreased, and the relative content of TN in leaves showed no change in the trend under the two planting modes. CC significantly increased the TN/TP (total phosphorus) of leaves, roots, and tubers. However, RC significantly increased the AN (available nitrogen)/AP (available phosphorus) of soil. The random forest analysis (RF) showed that abiotic factors contributed the most to TN/TK (total potassium) of roots, followed by TN/TK of tubers and TP/TK of roots. We found that abiotic factors had no significant impact on TP/TK of leaves and TN/TP of tubers. As expected, different planting patterns alter the plant's N (nitrogen)/P (phosphorus)/K (potassium), which in turn may modify N and P conservation strategies.
