Abstract:
Taking Nasturtium officinale R.Br.as the test material,soil as the object,watercress was planted in waterproof buckets with a submerged cultivation way,the effect of the duration of submerged cultivation on the soil salinity and nutrients was studied.The watercress was harvested 4 times during the experiment and the soil samples were collected at each havest.Soil was sampled 0-40 cm underground，with each 10 cm as a unit，the soil EC value，and the content of nitrate nitrogen，available phosphorus，available potassium and organic matter were determined.The results showed that the soil EC value，and the content of nitrate nitrogen，available phosphorus and available potassium content in 0-20 cm soil layer decreased with the extension of water logging time，among which the decline degree of soil EC value and nitrate nitrogen content was significant.While the content of nitrate nitrogen，available phosphorus and available potassium content in 20-40 cm soil layer increased and then decreased，and the amplitude were smaller.With the extension of water logging time，soil organic matter content in 0-10 cm and 20-30 cm soil layer decreased significantly and then increased slightly while decreased in 10-20 cm and 30-40 cm soil layers.The experiment concluded that long water logging time could reduce soil salinity and available nutrient，and increase organic matter content in surface soil (0-10 cm) and the main absorption layer of root system (20-30 cm)，which would play an important role in improving facility soil of high salt content and nutrient enrichment.
