Abstract:

4, 6, and 8 years old Kate apricot trees in fine culture management and conventional culture management in greenhouse were used to study the light intensity in a day, the relative light intensity at different levels in proportion of the total volume of the canopy and the statistical capacity of different branches, leaves, fruit and fruit quality. The results showed that the rate of relative light intensity greater than 30% of total solar radiation was 68.5% and 61.1% in fine and conventional management. The number of branch, leaf and fruit was 402,4697and 93 in fine management and 417, 4997, and 80 in conventional management, respectively. The weight of fruit, the weight of stone and the edible rate was 137.69 g, 3.85 g, and 97.20% in fine management, significantly higher than that of conventional management. So the model of fine management will be wild used in the south and middle part of Shanxi for its high yield and high quality.
