新型活性钙肥对苹果品质及产量的影响效果研究

Effect of New Active Calcium Fertilizer on Apple Quality and Yield

为研究新型生物钙肥-壳寡酸钙对苹果生长、品质及产量的影响,以市售腐殖酸和糖醇钙为对照肥料,进行壳寡酸钙产品对苹果生长品质及产量的影响效果研究。试验结果表明:喷施液肥壳寡酸钙后苹果树生长优势明显,春梢长度、叶片厚度、单枝花芽分化数量、75 mm苹果重量,较各种对照均有增幅;苹果喷施壳寡酸钙较对照每公顷增产5676 kg,增产率达14.31%,处理间差异达极显著水平(F=184.511),将各处理间差异进一步进行LSD多重比较,结果表明壳寡酸钙对苹果的增产效果达显著水平。

The effect of chitosan oligosaccharide acid calcium, a new biological calcium fertilizer, on applegrowth, quality and yield was studied. Commercial humic acid calcium and sugar alcohol calcium were used ascontrol fertilizers. The results showed that the test chitosan oligosaccharide acid calcium liquid sprayingfertilizer had obvious advantages on apple tree growth. The length of spring shoots, leaf thickness, number offlower bud differentiation on single branch, and 75 mm apple weight showed an increase in comparing with thecontrols. The hectare yield was 5676 kg more than that of control groups, and the increase rate was 14.31%.Variance analysis showed that the difference between treatments was highly significant（F=184.511）. Thedifferences were further multiply compared using LSD method, suggesting that the yield-increasing effect ofchitosan oligosaccharide acid calcium on apple was significant.
