本文讨论了荔枝生产失败的两种基本类型:即热带多数地区不开花以及亚热带地区不座果的问题。巳发表和未发表的资科指出,研究领域很可能克服荔枝生产上的这些问题。这些研究领域包括:荔枝花芽分化期(一年中最冷的3个月),应用生长抑制剂来抑制营养生长;花的负载量对于树体能量的平衡的影响以及继后植株对支撑果实生长和发育的能力,温度对花粉管生长的影响以及人工授粉克服低温导致的受精不良的效应;温度对花粉生活力和柱头的接受能力的影响,雌、雄花开放期品种间的差异以及与之相联系的授粉品种的需要,还有对不利条件的敏感性。
This article discusses two basic types of litchi failure: the non-flowering in most tropical regions and the lack of fruit in subtropical regions. Published and unpublished articles indicate that research areas are likely to overcome these problems in litchi production. These areas of research include: litchi flower bud differentiation (the coldest month of the year 3 months), the use of growth inhibitors to inhibit vegetative growth; flower load on the energy balance of the tree and subsequent plant growth on the support fruit And developing ability, the effect of temperature on the growth of pollen tube and the effect of artificial pollination to overcome the poor fertilization caused by low temperature; the effect of temperature on pollen viability and stigma receptivity; The need to contact the pollinated species, as well as the sensitivity to adverse conditions.
