Lintul5 - Simple generic model for simulation of crop growth - Phenology part
Introduction
The sim components in the package lintul5 implement the Lintul5 algorithms from (L5). They are designed to reproduce same results (up to rounding errors) as the original FST program.
The original model is subdivided into multiple sim components (which should be used in the following order to be as close as possible to the original algorithm).
- Irradiation
- PotentialEvapoTranspiration
- WaterBalance
- Phenology
- RadiationUseEfficiency
- Lintul5
Daylength calculation is performed by the transformer component AstronomicParametersTransformer
Phenology component calculates the phenology part
Description
The component calculates phenology according to original model's CROPP() routine.
It takes inputs from the AstronomicParametersTransformer.
It's outputs are used by WaterBalance, RadiationUseEfficiency and Lintul5.
For documentation of the algorithms please consult the orginal documentation (L5)
Changes to original
Control / Program flow
Has additional inputs iDoSow and iDoHarvest. The main routine starts running when iDoSow is true and runs every day until iDoHarvest is true.
- On iDoSow the model is (re)initialized and then the calculation is performed.
- On iDoHarvest all the outputs/states/rates are reset to their defaults (mostly 0). No further calculation is performed.
Within the calculation, the component checks - as in original Lintul5 - whether it should start at planting or at emergence and begins phenology development when CURRENT.DOY equals cIDPL or cIDEM. Therefore you have to make sure that iDoSow occurs before or at cIDPL resp. cIDEM, otherwise development won't start.
Additional Outputs
For the different phenology events, the day of year and date are output. There are as well booleans that become true only on the day when the event occurs and booleans that stay true when the event occurs until resetting/re-initialisation.
CropCycleCount is incremented at every DoHarvest.
Vernalisation
The phenology model has included vernalisation as in (L4V). By default vernalisation is switched off, so the model calculates as original Lintul5. To switch on vernalisation, the user has to provide the adequate parameters for vernalisation and to set cIDSL to 2.
Changes to vernalisation
Introduced a lower limit for the vernalisation factor (see (O))
