Abstract


In this paper, the water Drip Irrigation in Greenhouse dynamic changes of nitrogen transport field experiments and theoretical analysis . According to the actual situation of Drip Irrigation in Greenhouse tomatoes , on the basis of the analysis of field trials of tomato root distribution characteristics , the establishment of a drip irrigation tomato water movement mathematical model and tomato root water uptake empirical model field soil moisture dynamics simulation , the use of the simplified nitrogen Su migration piston model predicted nitrogen in the soil solute frontal . Through the the three greenhouse cherry tomatoes drip irrigation system field trials and the two greenhouse tomatoes fertilization field trials , highly efficient water-saving drip irrigation system for greenhouse tomatoes and optimal fertilization mode .
