More plot liquid manure distribution model group technologies comprise the following steps：
S1, after fertilizer applications determine, according to the fertilizer applications in each plot, by the plot in identical irrigated area point same interim
In irrigation group, different irrigated areas are divided in different temporary irrigation groups；
S2, in temporary irrigation group, the plot of identical fertilization type is assigned in a temporary irrigation group, Different Fertilization species
Assign in different temporary irrigation groups in plot；
S3, the area for calculating plot multiply the branch pipe flow ratio in dose per mu divided by plot；
Sa represents the area in plot, and Ka represents the dose per mu in plot, and Fa represents the branch pipe flow in plot, and Pa represents ratio；
Obtained in S2 in temporary irrigation group, Pa value identicals plot is assigned in an interim irrigation group, different Pa values
Plot is placed on different temporary irrigation groups；
S4, in the temporary irrigation group obtained after S3 terminates, go to determine the ground block number in irrigation group using knapsack algorithm, its
In, the capacity of knapsack is the metered flow of water source pump, and volume, the value that can be put into knapsack article are the branch pipe flow in plot；Most
Plot branch pipe flow sum is closest to the metered flow of water source pump in the irrigation group obtained afterwards, and dose in plot is closest to fertilizer
The maximum Sheng fertilizer amount of measuring tank.
Further, more plot liquid manure distribution models based on water and fertilizer management equipment, described more plot distribution models can roots
The factually project situation on border, the distribution situation in plot, the metered flow of water source pump, the area in plot, the species, actual of crop
Plot under engineering project is divided into multiple irrigation groups and carries out irrigation by rotation by fertilising situation, the branch pipe flow in plot.
Further, more plot liquid manure distribution models based on water and fertilizer management equipment, the algorithm with subproblem specifically, determined
Adopted state：I plot is just put into the maximum stream flow that can be obtained in the water source that a capacity is v, its state before F [i, v] is represented
Equation of transfer is：Wherein, Ci represents to be put into i-th of plot F [i, v]=max { F [i -1, v], F [i -1, v-Ci]+Ci }
The flow at the water source of consuming, using above-mentioned state transition equation, according to dynamic programming algorithm, yield less than equal to water source pump discharge
And the plot packet of most water receiving source pump discharge.
In summary, effect of the invention is：The invention provides a kind of more plot liquid manure based on water and fertilizer management equipment
Distribution model, this method are mainly used in water and fertilizer management equipment, when more plot irrigations can be achieved, in this manner by multiple plot
It is divided into multiple optimal rotation flow groups, ensures the fertilization effect in each plot with estimated, while ensure the completion of maximal efficiency
Irrigate.
