Description
技术领域:
本发明涉及一种快速鉴别桃花芽受冻害的方法，属于种植技术领域。
背景技术:
低温对植物的影响不仅表现的外部形态上，对细胞的生理生化也有较大的影响;大量研究结果揭示和证实，低温对细胞膜体系的损伤是造成植物寒害的根本机制，其主要原因是由于冰冻引起的细胞脱水而导致细胞膜双层向六角形相的转变以及膜的破裂,冻害主要表现在以下几个方面：1) 细胞膜遭到破坏，膜内大量溶质外渗；2) 细胞原生质流动减慢或停止；3) 水分代谢失调，吸水能力和蒸腾速率都明显下降；4) 光合速率减弱，叶绿体分解加速，叶绿素含量下降，加之酶活性受到影响，因而光合速率明显降低；5) 呼吸速率大起大落；6) 有机物分解大于合成；目前主要采用植物防冻剂进行防护，但防护效果差，植物受冻严重，迫切需求一种快速鉴别桃花芽受冻害的方法及防冻措施。
发明内容:
为了缓解现有技术的不足，本发明的目的在于提供一种快速鉴别桃花芽受冻害的方法。
为了实现上述目的，本发明采用如下技术方案：
快速鉴别桃花芽受冻害的方法，包括以下内容：
（1）在受低温霜冻影响的桃树种植地随机选择5-6个区域，每个区域随机选取桃树数条；
（2）根据桃花芽的受冻害程度制定分级标准；
（3）通过桃花芽受冻害指标，结合步骤（2）所述的分级标准对所选取桃花芽的受冻害情况进行调查并记录；
（4）综合上述数据，得出所选取的桃花芽的受冻害等级。
所述的桃花芽受冻害程度的分级标准为1级：桃花芽已死亡；2级：桃花芽枯萎；3级：桃花芽是冻伤而未死；4级：部分变水渍状；5级：桃花芽生长正常。
所述的桃花芽受冻严重时喷洒防冻剂，所述的防冻剂由如下组成原料配制而成：葡萄汁液10-12、海藻多糖10-15、硼酸4-6、赤霉素1-1.5、萘乙酸0.5-0.8、6-苄基氨基嘌呤1-2、水溶性微肥4-5、硫酸亚铁铵3-4、磁化水60-80。
本发明的有益效果：
与现有技术相比，本发明可以快速有效的监测桃花芽的受冻情况，并实时对受冻芽进行防冻处理，本发明对桃花芽受害程度进行详细分级，更有利于桃花芽受冻害情况作出准确的判断；从而降低抗寒能力，减少花芽受冻死亡，提高花芽抗寒能力。
具体实施方式:
实施例1：快速鉴别桃花芽受冻害的方法，包括以下内容：
（1）在受低温霜冻影响的桃树种植地随机选择5-6个区域，每个区域随机选取桃树数条；
（2）根据桃花芽的受冻害程度制定分级标准；
（3）通过桃花芽受冻害指标，结合步骤（2）所述的分级标准对所选取桃花芽的受冻害情况进行调查并记录；
（4）综合上述数据，得出所选取的桃花芽的受冻害等级。
所述的桃花芽受冻害程度的分级标准为1级：桃花芽已死亡；2级：桃花芽枯萎；3级：桃花芽是冻伤而未死；4级：部分变水渍状；5级：桃花芽生长正常。
所述的桃花芽受冻严重时喷洒防冻剂，所述的防冻剂由如下组成原料配制而成：葡萄汁液11、海藻多糖12、硼酸5、赤霉素1.2、萘乙酸0.6、6-苄基氨基嘌呤1.5、水溶性微肥4.5、硫酸亚铁铵3.5、磁化水70。
