Abstract:
The different green manure growth characteristic，biomass and nutrient characteristic and effect of green manure application on raw clay soil nutrients and microbial flora in trough greenhouse were studied by randomized block design with summer idle land (no green manure) for the control matrix.The results showed that the sweet corn，sorghum and sudan grass three kinds of green manure could produce higher biomass and nutrient accumulation during summer recreational season in trough greenhouse with short time (50 days).The planting and green manure decreased the soil pH value，meanwhile it may increased the soil organic matter，available nitrogen，phosphorus and potassium content compared with the control.Among them with sweet corn，sorghum and sudan grass was obvious.The planting and green manure changed microbial community structure，increased the total soil bacteria，bacteria and actinomyce，reduced the number and proportion of fungi，while significantly improved soil microbial environment and increased the ratio of bacteria to fungi (B/F).And sweet corn，sorghum and sudan grass were more significantly.The planting and green manure could be use as raw clay soil fertility of an effective measure to implement in trough greenhouse.
