秭归县柑橘延迟锯砧高接换种技术 实验与研究

高接换种是以成年树为基础实施的一种品种改良技术,具有易成活、恢复快、周期短的特点。根据湖北三峡地区柑橘产区高接换种实践表明,一般采用高接换种的成年树,都可达到“第一年嫁接,第二年恢复树势,第三年丰产”的目标1]。采用延迟锯砧高接换种技术,延迟一年清砧锯砧,在高接换种基础上,可明显减少一年恢复期,而当年产量不减产,只需一年抽梢恢复期,效益明显提高。

High grafting technology of citrus delayed saw in Ziguicounty Experiment and research

The high grafting species is a kind of improved technology based on the adult tree, which has the characteristics of easy survival, fast recovery and short cycle. According to the practice of high grafting of citrus in the three Gorges area of Hubei province, it is suggested that the adult tree with high grafting can achieve the goal of " grafting in the first year, restoring tree potential in the second year, and high yield in the third year" 1 ]. Using delay saw anvil high connection technology, delaying a year clear anvil saw, on the basis of high - grafting, it can obviously reduce the recovery period of one year, and the yield of the year is not cut, only need to draw the recovery recovery period, the benefit is obviously improved.
