桃树对气候非常敏感。要了解某些栽培措施的效应,就必须详细了解贴地层的小气候及其对植株的影响。即使我们可以在一定程度上改善这些控制耐寒力和植株周围环境的因子,然而某些气候条件往往超越植株所能恶受的能力。冬期突然大幅度降温会引起严重生理反应,导致植株死亡。气象条件和细菌性溃疡及孢子性溃疡等病害之间存在一定关系。小气候的极端最高和最低,是桃树寒害和早期死亡的主要因子。如果要避免桃树在某些年份遭受巨大损失。预防这种寒害是很重要的。这个问题基本上要考虑从生理上解决,病理上是次要的。若不发生寒害或其它损害,病原体的浸染是罕见的。本试验目的在于确定寒害可能发生的时间和条件,并提出适当的防寒措施。 Peach trees are very sensitive to the climate. To understand the effects of some cultivation measures, one must understand in detail the microclimate affixed to the formation and its impact on the plant. Even though we can improve these factors controlling the cold tolerance and plant environment to some extent, some climatic conditions tend to outweigh the plants’ ability to withstand them. Sudden sudden sudden winter temperature will cause serious physiological reactions, leading to plant death. Meteorological conditions and bacterial ulcer and spore ulcers and other diseases there is a certain relationship. The extreme highs and lows of the microclimate are the major causes of cold damage and early death in peaches. If you want to avoid peach trees suffered huge losses in some years. It is important to prevent this chill. Basically, this issue should be considered physiologically and pathologically secondary. In the absence of chilling injury or other damage, the dissemination of pathogens is rare. The purpose of this test is to determine the time and conditions of possible cold damage and to propose appropriate measures to prevent it from freezing.
