通过室内试验,研究了不同施肥方式和肥量对膜孔自由入渗累计入渗量的影响。结果表明:施肥方式对膜孔自由入渗量有影响,在相同时间内入渗量表现为灌施>深施>表施;施肥量对膜孔自由入渗量也有影响,在不同施肥方式下,随着肥量的增加,相同时间内膜孔自由入渗量增大,且不同施肥方式下不同肥量的膜孔自由入渗量与时间之间均符合Kostiakov入渗模型。
Through laboratory experiments, the effects of different fertilizing modes and amount of fertilizer on cumulative infiltration of membrane holes were studied. The results showed that the fertilization mode had an impact on the free infiltration of the membrane pores, and the infiltration rate of the same time showed irrigation> deep application> surface application; the amount of free fertilizer also had an impact on the free infiltration of membrane pores. Under different fertilization modes With the increase of the amount of fertilizer, the free infiltration rate of the membrane pores increased at the same time, and the infiltration rate and time of the membrane pores with different amounts of fertilizer under different fertilization modes all met the Kostiakov infiltration model.
