Abstract

Abstract: By simulating the rainfall method, the rainfall test of pig manure with different stacking time under natural conditions was carried out. At the same time, the loss of different nitrogen form runoff in pig manure under natural storage conditions under the conditions of straw, soil and bare cover were compared and analyzed. The results showed that the nitrogen loss of pig manure was closely related to rainfall, the concentrations of total nitrogen, ammonia nitrogen and nitrate nitrogen in pig manure runoff decreased with the increase of rainfall; Nitrogen concentration and loss intensity of the fresh pig manure runoff piled for 7 days and pig manure runoff piled for 30 days were higher, nitrogen of runoff piled for 90 days was more easily lost through runoff compared with runoff piled for 60 days. The nitrogen in pig manure was mainly lost in the form of ammonia nitrogen, the average loss intensity of ammonia nitrogen and nitrate nitrogen was 78.1 g/t and 54.9 g/t, respectively; The coverage treatment can significantly reduce the loss of pig manure nitrogen, and the soil cover treatment was better than the straw cover treatment.

Key words: decentralized, livestock manure, simulated rainfall, nitrogen, loss characteristics
