【摘要】 为了探索苹果生长与气象因子的关系,发展优质高产特色产业,运用陇东南"花牛"苹果产地1981—2016年试验资料及气象资料,建立苹果产量、质量与气象因子相关关系模型。结果表明,影响天水"花牛"苹果产量质量的主要气象因子是热量条件。1981—2016年,随气候变暖,"花牛"苹果含糖量、硬度下降,含酸量上升。含糖量与7—8月平均气温日较差呈显著正相关;含酸量的倒数与7、8、9月平均气温的倒数呈显著负相关;硬度与7、8、9月平均气温的自然对数呈负相关;果型指数与8月中旬平均日照时数呈显著负相关。果实累积重量及果径大小与≥10℃积温相关性显著,可用S型曲线模拟。充分利用气候资源,在果树生长的关键时期加强果园水肥、病虫害、修剪等各项管理,是提高果品产量及商品等级的重要环节。更多还原

【Abstract】 The paper aims to explore the relationship between apple growth and meteorological factors, thus todevelop specialty industry with high quality and high yield. Based on the experimental data and meteorologicaldata of Huaniu apple producing area in southeast Gansu from 1981 to 2016, we established the applecorrelation model between yield and quality and meteorological factors. The results showed that: heat conditionwas the main meteorological factor affecting yield and quality of Huaniu apple in Tianshui; during 1981-2016,under the background of climate warming, fruit sugar content and fruit hardness decreased and fruit acidcontent increased; sugar content and the diurnal average temperature range in July and August had asignificantly positive correlation, the reciprocal of fruit acid content and the reciprocal of the averagetemperature in July, August and September had a significantly negative correlation; fruit hardness and thenatural logarithm of average temperature in July, August and September had a negative correlation; thecorrelation between fruit cumulative weight, diameter cumulative growth and ≥10℃ accumulated temperatureall could be simulated by "S" curve at the fruit growth stage. Making full use of climate resources,strengthening the management of water and fertilization, the controlling of diseases and insect pests, and theadopting of pruning in the critical stage of fruit growth are important to improve apple yield and commodity grade.更多还原
