一、前言《农业气象》1981年第1期发表了一些对橡胶树寒害类型及其指标鉴定的论述,其中反映了某些不同的观点,特别在辐射型方面的指标,存在着下列的几点分岐。文献[1]认为,辐射型受害有两个亚型:急发式霜害和累积式寒害。二者成因不同,指标计量方法应有区别,文献[2]在处理上把两个亚型作为一个型,其指标均以同一方法(辐射积寒法)鉴定。文献[1]认为,急发型霜冻是零下低温使植株受冻形成的。决定因子是极端低温的强
I. Preface The first edition of “Agricultural Meteorology” in 1981 published some expositions on the types of rubber tree chills and the identification of indicators, which reflected some different opinions, especially on the radiation type, with the following differences: . Literature [1] that there are two subtypes of radiation damage: rapid onset of frost damage and cumulative cold damage. The causes of these two different indicators should be different methods of measurement, the literature [2] in the treatment of the two subtypes as a type, the indicators are the same method (radiation cold method) identification. Literature [1] that the emergency type of frost is zero freezing cold plants. The determinants are extremely cold
