Abstract:
The seeding of 10-year-old Armeniaca vulgaris L.var.glabra S.X.Sun were used as the research material,single factor experiment design was conducted by adopting afforestation，plants was sprayed with four different types and concentration levels plant growth regulator in the bud dew calyx stage of spring，spraying water as control (CK)，based on the wild florescence phenology，statistical analysis，the study was carried out on the effect of different types of plant growth regulator，different levels and different processing methods on florescence of A.vulgaris L.var.glabra S.X.Sun in Dunhuang，not only safe and effective，but also economic and reasonable measures for delaying florescence of A.vulgaris L.var.glabra S.X.Sun were explored,in order to solve the problem of low temperature damage of A.vulgaris L.var.glabra S.X.Sun in production practice in early spring.The results showed that the flowering period of A.vulgaris L.var.glabra S.X.Sun treated with four plant growth regulators was generally delayed，among which NAA was the best.Among the four concentrations ranging from 50 mg?L-1 to 2 000 mg?L-1，CEPA，ABA，GA and NAA had the most significant effect on florescence delay.The treatment effect of ‘irrigation+750-1 000 mg?L-1 CEPA’ was the best，which can delay the early flowering period of A.vulgaris L.var.glabra S.X.Sun in Dunhuang for 6-7 days.
