Abstract:
By the method of field observation and analysis,the effects of phenological period of P.armeniaca L.growth inside the heliogreenhouse on the temperature changes were studied.The results showed that compared with open land，the phenological period of P.armeniaca L.growth inside the heliogreenhouse had an apparent change.During the early stage,the same phenophase was lengthened in contrast to outdoor snowing；while after the fruit core-harding stage，it was apparently shortened.In January，the temperature in the heliogreenhouse could reach 10.2~11.4℃.Besides,the P.armeniaca L.was budding，blooming and extending shoot almost simultaneously.At this time,the ground temperature varied from 5.8~10.2℃;root system did not enter into the time of rapid growth.Whereas,the blossom was dropping very gravely.Then，at the fruit colour period and mature stage,the difference in temperature inside the heliogreenhouse was smaller than that of oudoor’s,it was 10.5~12℃,which had a negtive effect on the high quality fruit production.
