银杏树定植后,一般不再移动。但因栽后密度过大、过小或老园改建、绿化美化景点时,往往要对10—20年生的大树移入或移出。在以往的成年银杏树移栽中,成活率低,丰产性差。对此,我们进行了多年的生产实践,总结出一套成年树移栽丰产技术。 一、移栽技术 1.断根处理。对计划移栽的单株,在前一年秋季进行断根处理。方法是:以树干周围1—1.5米为半径,挖深约1米、宽约0.2米的沟,将根切断。沟内施足有机肥料,促进伤口愈合,萌发新根。树越大,越需断根处理。
Ginkgo tree colonization, generally no longer move. However, due to transplanting density is too large, too small or the old park reconstruction, landscaping landscaping, often to 10-20 years old tree into or out. In the previous adult ginkgo transplanting, the survival rate is low, poor yield. In this regard, we conducted many years of production practice, summed up a set of adult tree transplanting high yield technology. First, the transplanting technology 1. Root treatment. Plants planted for transplanting were cut off in the autumn of the previous year. Method is: 1-1.5 m around the trunk as a radius, digging about 1 m deep, 0.2 m wide ditch, the root cut off. Ditch enough organic fertilizer, promote wound healing, germination of new roots. The bigger the tree, the more need to cut off the root.
