Other claims from this paper (13)
- Intervention effect Increasing nitrogen rate significantly increased plant height, ear length and leaf length of double cropping rice.
- Intervention effect Increasing nitrogen rate significantly increased basic leaf angle of double cropping rice.
- Observation Layer LAI and upward accumulated LAI of early and late rice were greater at booting stage than at 12 d after heading.
- Observation Layer LAI was greater in mid canopy than in upper and basal canopy.
- Intervention effect Layer LAI and upward accumulated LAI in upper and mid canopy increased with increasing nitrogen rate.
- Method / resource The distribution of upward accumulated LAI with relative height followed a sigmoid curve described by a Logistic equation (R2 > 0.99).
- Observation Canopy IPAR of early and late rice was greater at booting stage than at 12 d after heading.
- Intervention effect Canopy IPAR of early and late rice increased with increasing nitrogen rate.
- Observation Diurnal variation of IPAR was smaller at noon than in the morning and afternoon.
- Association Lower canopy IPAR was observed for the compact plant type of early and late rice cultivars.
- Method / resource The relationship between canopy IPAR and downward accumulated LAI was described by IPAR = a (1-e-b×LAI) (R2 > 0.88).
- Observation On the horizontal plane, IPAR was smaller and light fleck variation was greater in upper and mid canopy than in basal canopy.
- Observation IPAR at the same canopy height was non-uniform on the horizontal plane.
