Other claims from this paper (15)
- Intervention effect Higher planting density reduced the biomass and its distribution proportion in spike of wheat.
- Intervention effect Higher planting density was associated with declined stem quality of wheat.
- Association After jointing, the edge line had higher spike rate, number of effective spikes and plant dry weight than the second and central lines.
- Association After jointing, the edge line had higher outside diameter, culm wall thickness and internode filling degree than the second and central lines.
- Association After jointing, the edge line had higher mechanical strength than the second and central lines.
- Association Plant density influenced the border effect on effective spikes, with the maximum number at 1.8 million plants per hectare.
- Intervention effect Higher planting density significantly increased the spike number in the second and central lines of wheat.
- Intervention effect Higher planting density increased plant height and height of gravity centre of wheat.
- Intervention effect Higher planting density decreased plant weight and biomass distribution proportion in spike of wheat.
- Intervention effect Higher planting density dramatically declined internode filling degree and mechanical strength of wheat stems.
- Intervention effect Higher planting density resulted in the occurrence of early lodging in wheat.
- Intervention effect Higher planting density was associated with high lodging degree and lodging area percentage in wheat.
- Intervention effect Nitrogen application had positive effects on the lodging index and mechanical strength of the central line of wheat.
- Intervention effect The general effects of the two nitrogen treatments on wheat were not significant.
- Recommendation A plant density of 1.2-1.8 million per hectare is optimal for relay intercropping wheat in the hill area of Southwest China.
