- Abstract:
- To explore the law of water and salt movement in drip irrigation of cotton field, soil moisture and salt are studied from the horizontal and vertical directions in different stages of cotton using drying and soil conductivity. The results showed that the soil salt in 0-10 cm was the highest before first irrigation throughout the growing period of cotton. With the post-reproductive period, each soil layer salt quantity have the increase of different level and resulted to the soil salt accumulation. Drip emitter contain salt quantity is relative lower mainly due to constant water drip and infiltration, which resulted to form a low-salt zone in the main root system layer.
