秋施N、P、K无机肥对中华寿桃树体生长及果实品质的影响

Effect of Tree Growth and Fruit Quality of Zhonghua Peach Applying on N,P and K Fertilizers

本文以15年生的中华寿桃为研究对象,通过连续3年的N、P、K无机肥处理,研究树体的枝类和坐果情况及果实品质变化。研究结果表明,N、P、K无机肥处理都提高了树体的总枝量,N肥处理提高了结果枝和营养枝的枝量,P、K肥处理提高了结果枝的枝量,降低了营养枝的枝量;P、K肥处理的坐果率和产量相比CK都有所提高。各肥料处理均提高了果实的硬度、可溶性糖、TSS/TA、Vc含量等指标。总之,N、P、K肥处理后,树体枝类组成明显优化,果实产量、品质都提高。秋施N、P、K肥是一项较好的农艺措施,生产中可考虑应用。

The changes of tree branches,fruit setting and fruit quality were studied on 15 years old Zhonghua applied in N,P and K Fertilizers for 3 years.The results showed that the total branch quantity of tree was increased with the treatment of applying N,P and K fertilizers.The quantity of fruiting and was increased with N.The quantity of fruiting branch was increased and foliage branch was decreased with P、K.The fruit setting rate and yield Compared with P、K were higher than that of CK.The fruit firmness,soluble sugar,TSS/TA and Vc content was increased and the tree branch composition was optimized obviously,and the fruit yield and quality were improved with N,P and K.It is a good measure to apply N,P and K fertilizers in Planting.
