摘要

Through the experiment of different plant spaces with urea applied, the paper studied the influence of plant spaces on soil nitric nitrogen dynamical changes under film hole irrigation and the nitric nitrogen content of the growing period was determined. The result showed that 40cm of plant space promoted the transformation of urea, and when the urea transformed fully, the nitrate nitrogen content of 40cm plant space was larger than the space of 25cm; Under the low fertilizer, the nitrate nitrogen content in the 40cm plant space was higher than that in the 25cm plant space at the same depth; under the high fertilizer, 40cm plant space promoted nitrate nitrogen transporting down and horizontally, the nitrate nitrogen accumulation peak was below and the peak value was higher than 25cm plant space in the profile being 3cm from the film hole center and the nitrate nitrogen content of 40cm plant space was higher than the 25cm the profile being 8cm from the film hole center. Above researches could provide the basis for rational fertilization of farmland and nitrate environmental impacts on assessment.
