Abstract:
Taking 7-year-old apple varieties ‘Xiahong’‘Huashuo’ and ‘Fuji’ as experimental materials,45% lime-sulfur crystal,organic calcium preparation and carbaryl were used for flower and fruit thinning,the effects of different chemical agents were studied,in order to provide reference for apple chemical flower and fruit thinning.The results showed that the three chemical agents have different degrees of flower and fruit thinning effects on ‘Xiahong’‘Huashuo’ and ‘Fuji’ apple varieties.According to the comprehensive comparison of single fruit ratio,fruit setting rate,empty rate and fruit quality index,the best flower and fruit thinning effect was 150 times of 45% lime-sulfur crystal,200 times of organic calcium preparation and 2.5 g·L-1 carbaryl.
