Abstract:
Five-year-old jujube was used as test material in southern Xinjiang,the drip irrigation was carried out on five different types (natural water temperature,10 ℃,20 ℃,30 ℃,40 ℃),and the whole strain was collected by gauze.The rule of warming drip irrigation on the flower drop and fruit drop of jujube were studied,in order to provide strong technical support for the quality and efficiency of jujube in Xinjiang.The results showed that,①Under the condition of warming treatment,the change trend of jujube trees was similar,and the concentrated flowering period was distributed from June 10 to July 20,and the concentrated fruiting period was distributed from July 15 to August 4.Except that there were 3 peaks of flowering in the treatment at 20 ℃,and there were two peaks of flowering and fruit drop in the other treatments.②The concentrated flowering period and the total flowering period in the growth period were 20 ℃>30 ℃>40 ℃>10 ℃>natural water temperature,20 ℃,30 ℃ treatment and 10 ℃,natural water temperature treatment was significantly different.③Total fruit drop performance was 30 ℃>40 ℃>20 ℃>10 ℃>natural water temperature,fruit storage performance.It was 20 ℃>30 ℃>40 ℃>10 ℃>natural water temperature,and the fruit drop rate was 30 ℃>natural water temperature>40 ℃>10 ℃>20 ℃.The fruit setting rate varied between 0.82% and 1.12%,and the difference between treatments was not significant.The warming water treatment had a significant effect on the flowering and fruit setting of jujube trees.The water temperature treatment at 30 ℃ could promote the flowering of jujube trees and increase the fruit setting rate obviously at 10 ℃.
