Abstract:
Taking apricot ‘Longquanwu Xiangbai’ as material,the factors influencing the percentage of fertile fruit,garden soil nutrient conditions,mineral nutrition of trees,weather conditions in flowering period,cultivation and management measures were investigated.Fruit setting rate after spraying different liquid were studied,to discuss the factors that influncing fruit setting rate and solving measures,in order to provide a theotetical basis for high yield production cultivation management.The results showed that,the factors influencing the lower percentage of fertile fruit of apricot ‘Longquanwu Xiangbai’ mainly include the higher percentage of incomplete flower;pollination incompatibility;organic matter and nitrogen deficiency in soil;manganese and borax deficiency in tree;gale,low temperature and dry weather at anthessis;extensive management in orchard.Spraying carbamide and borax solution,manganese sulfate solution or water significantly increased the percentage of fertile fruit of apricot ‘Longquanwu Xiangbai’.
