Abstract:
The Vicia villosa var.，Lolium perenne L.，and Raphanus sativus L. were used as test materials.A pot experiment was carried out.The characteristics of water leaching and nitrogen,phosphorus leaching in soil under different green manure combinations were studied in order to effectively promote green manure planting and improve water and soil conservation of soil in full bloom.The results showed that there was a certain difference in the change trend of the growth rate of various green manures，and the growth rates of the two treatments in the treatment of V.villosa var.+ R.sativus L.were higher than that of the same green manure in other treatments.In the blooming period，the each pot of aboveground fresh weight in the treatment with L.perenne L.was higher than other treatments，and the each pot of underground fresh weight was higher than the others in the treatment with R.sativus L..Under different watering rates，the treatment of single species of L.perenne L.，V.villosa var.+ R.sativus L.and V.villosa var.+ R.sativus L.+ L.perenne L.effectively reduce the amount of leaching water loss，and when the watering amount for treatment of V.villosa var.+ R.sativus L.was 1 000 mL and 1 500 mL the reduction was the largest，92.68% and 81.55% respectively；the treatment of single R.sativus L.，V.villosa var.+ R.sativus L.and R.sativus L.+ L.perenne L.could effectively reduce soil total nitrogen and total phosphorus leaching loss.Among them，when the watering volume was 1 000 mL and 1 500 mL，the reduction of the treatment of spore V.villosa var.+ R.sativus L.was the largest，which were 92.31%，93.21% and 77.88%，92.53%，respectively.When the watering volume was 2 000 mL，the total phosphorus leaching loss in the soil decreased the most，which was reduced by 94.34%.Through correlation analysis，it was concluded that the leaching water loss，total nitrogen and total phosphorus leaching loss were significantly related to the fresh weight of the underground.It was concluded that planting green manure of different families and their combinations could effectively reduce soil water leaching loss，and reduce soil total nitrogen and total phosphorus leaching loss in different degrees，and the effect of some mixed planting treatments was better than that of single planting treatment in full bloom.The mixed planting of V.villosa var.and R.sativus L.had the best effect，and could be further promoted.
