Cultivar Selection And Techniques Integraion Applied For Peach Protected Cultivation In Shanshan County, Xinjiang

There are abundant light and heat resources in Shanshan County, Xinjiang. Recently, facilities peach industry developed rapidly in the region. At present, suitable cultivar and cultivation techniques are urgent questions. In th paper, with Prunus persica var.Nectarine cv.'Xinyouyihao', Prunus persica var. nectariana cv.'Shuguang', Prunus persica cv.'Xiaxiangji',Prunus persica cv.'Jiazhouzaotian' and Prunus persica cv. 'Hanguodabaitao' as material, cultivar selection experiment was performed in facilities peach demonstration plot located in Pizhan town, Shanshan county,Xinjiang Uyguer Autonomous Region. Therfore, a series cultivation techniques involving of facilities peach were summaried comprehensively. The main results were showed as following:1.Comprehensive investigation and analysis on botanical features, phenological phase in greenhouse, perfermance and qualities of five different varieties of peaches were performed. In the above nectarine cultivars, by comparison with 'Shuguang','Xinyouyihao' is more powerful growth potential, higher budding force and branching, higher fruit set percentage as well as higher yield and higher soluble solids content. In the three peaches tested in the experiment,'Jiazhouzaotian' has more stronger growth potential, higher budding force and branching than 'Xiaxiangji' and 'Hanguodabaitao' as wel as higher soluble solids content and shorter fruit developmental period. In conclusion,'Xinyouyihao' and 'Jiazhouzaotian' were respectively selected as ideal necrarin and peach cultivars to extention in the region.2. In the experiment, cultivation and management mode involving of facilities peach was investigated in the past several years. The main items included prunning, temperature management, flower and fruit management, fertilization and pest control. For example, in the greenhouse, open-vase form should be used in the tree shape selection. In the dormant period, prunning should be paid attention to specially. After buckling shed, the temperature increasing time was determined according to chilling requirement. In the blooming period, bee pollination was used to increase fruitset percentage. To improve fruit quality by using flower and fruit pruning. Properly adding base fertilizer, pre-blooming fertilizer as well as fruit enlargement fertilizer and postharvest fertilizer were used to improve tree vigor and increase fruit yield. The temperature and humid management in the germination period,blooming stage, fruit expansion period and fruit coloring period should be strengthen especially. In the autumn and in the 10 days after buckling shed, calcium polysulfide should be spayed to protect prevent the aphids and red spiders. According to the above techniques, field cultivation techniques and management anniversary calendar of peaches in greenhouse in Shanshan County were worked out in the study.
