Abstract: The effect of Chitosan oligosaccharide acid calcium, a new biological calcium fertilizer on apple growth, quality and yield was studied. Commercial humic acid calcium and sugar alcohol calciumwere used as the control fertilizers. The results show that the test Chitosan oligosaccharide acid calcium liquid spraying fertilizer has obvious advantages on apple tree growth. The length of spring shoots, leaf thickness, number of flower bud differentiation on single branch, and 75mm apple weight show an increase relative to controls. The acre yield increase 5676 kg than control groups, and the increase rate is 14.31 %. Variance analysis shows the difference between treatments was highly significant (F value = 184.511). The differences were further multiple compared using LSD method, suggesting that the yield-increasing effect on Fuji Apple of Chitosan oligosaccharide acid calcium is significant.
