Abstract:
With different planting density apricot orchards as research objects,by using ‘HOBO’ were portable-meteorological station and canopy analyzer with type of LAI-2200,the changes of PAR and LAI on different parts in apricot orchards with different planting densities were analyzed,in order to understand the light change rule in apricot orchards with different planting density,and laying a foundation for choosing the reasonable density for orchard construction,training and pruning.The results showed that PAR in one day of apricot orchards with different planting density all presented the change rule of ‘low-high-low’;The PAR of inter-plant,inter-row and canopy center in the apricot orchards from big to small in turn was:inter-row>inter-plant>canopy center.The LAI value of apricot orchards which planting density of 2 m×4 m,4 m×4 m and 4 m×6 m were between 3.0～5.0,the LAI value of apricot orchards which planting density of 4 m×8 m and 8 m×8 m were less than 3.0.The change of LAI in apricot orchards with different density from big to small in turn was:2 m×4 m＞4 m×4 m＞4 m×6 m＞4 m×8 m＞8 m×8 m.In a conclusion the PAR and LAI value of different parts in apricot orchard were closely related to the planting density,and the PAR and LAI value of different parts in apricot orchard with 4 m×6 m planting density was reasonable,apricot orchard with this density the light was well distributed,and the light transmittance was high.
