Abstract:
Display atemoya fruit wind experiment, plants with windbreak effect horizontal trellis training mode is the best, had the lowest branches broken rate; orchard setting windbreak net can reduce the branches broken rate, the scope of protection of windproof net height of 7 times the distance. The injury of fruit bruises victimization rate was the highest in the storm, in the strong wind coming prior to removal of surrounding foliage and fruit jacketed set fruit net treatment had a protective effect of fruit, can significantly reduce the fruit injured rate. Atemoya post disaster restoration results show the treatments of pruned, night lighting in late September and early October, that blossom rate can reach 82.9% and 72.7% respectively (control group 42.8% and 24%); treatment group fruits were harvested in April, average fruit weight 717.2g (control group, produced in March, fruit weight 547.8 g). The above results indicate, by pruning and night light treatment after the wind disaster, can promote atemoya blossom and fruiting in November, to achieve rapid restoration goals.
