Based on the survey of growth and decline regularity of A. japonicus and V.sativa plants in interplanted wheat fields,a preliminary study into the influence of the twoweed species' infestation on the yield of interplanted wheat was conducted,the predictionmodel of wheat yield loss was established and the complex weed control targets for the twoweed species were advanced in combination with the economic tresholds under the localconventional weeding practices. The results of experiments showed that there were positivecorrelations between wheat yield loss and occurrence rates of A. japonicus and V. sativa,themultiple correlation formula was: Y = 0.019 1x1 + 0. 091 1x2 + 6. 572 9, the complex weedcontrol targets were dynamic.

The growth and decline regularity of beneficial microbes in the casing soil was analyzed by means of plate cultivation of the diluent prepared with the soil samples collected during the different growth periods of Agaricus bisporus —— the periods of the soil casing, full spawn-run, primordium formation, before the harvest and 2 days after the harvest. The results showed that the quantity of milky Bacillus, Azotobacter and Pseudomonas increased before the primordium formation and after the harvest of A.bisporus, the quantity of Streptomyces changed smoothly, while the quantity of ashy Bacillus tended to decrease continuously.
