[0140] Test example 1

[0141] According to examples 1-3 and comparative examples 1-3, corn and soybean are compound planted respectively, the seedling survival rate is counted, and after harvesting, the yield of each group is counted as follows, and the soil nitrogen fixation enzyme activity (nmol / g / h) is detected after corn and soybean are separated from the field.

[0142] Corn yield Soybean yield Plant stand per hectare Nitrogenase activity Example 1 1256.46 kg / acre 511.09 kg / acre 94.42% 2.57 Example 2 1298.71 kg / acre 503.62 kg / acre 92.11% 2.63 Example 3 1372.11 kg / acre 523.16 kg / acre 96.77% 2.71 Comparative Example 1 1136.95 kg / acre 496.07 kg / acre 88.03% 2.44 Comparative Example 2 1023.92 kg / acre 471.23 kg / acre 83.96% 2.25

[0143] As can be seen from the table, the yield of corn and soybean compound planted by using the method of the application is higher, the seedling survival rate is good, the soil nitrogen fixation enzyme activity is high, the quality of corn and soybean compound planting can be significantly improved, and it is worth further popularization.
