尤眼生产上常见投产树早衰,产量低现象.据观察结果,造成“小老树”和“衰老树”的原因与不按其生育规律进行科学管理,以及大生年挂果超负荷有密切关系.应用形相诊断和叶片营养分析可以从宏观和微观两方面了解树体的负担程度.这里介绍一种形相诊断鉴别的方法:外部植株形态可以反映植株营养水平与产量的相互关系.因此,采用形相诊断可以帮
According to the observation results, the causes of “small old trees” and “aging trees” are closely related to the scientific management not in accordance with their reproductive laws and the overloading of fruit hangings in their pupils. Application of morphological diagnosis and leaf nutrient analysis can understand the extent of tree burden both in macroscopical and microcosmic aspects.A method for the identification of the form of the phase is introduced here.The morphology of the external plant can reflect the correlation between plant nutrient level and yield.Therefore, Can help
