摘要:
为促进油橄榄丰产稳产，以生产上花量大、坐果率低的油橄榄品种萼植8号、豆果、小苹果为试材，研究了疏除花量及果量的1/4、1/3、1/2对油橄榄结果和产量的影响，并对疏花疏果后树体叶片养分含量状况进行了分析。结果表明：在盛花期疏除总花量的1/4，可有效增加单株产量，而疏除总花量的1/2对提高花后15 d坐果率效果最显著，疏果量为1/4时增产效果最佳，同时，稳果率及单果重也达到最高，这与叶片中N、P、K、Ca、Zn含量的变化规律呈现一定的相关性，表明疏花疏果可有效减少树体营养元素的消耗，有利于促进油橄榄花果的正常发育，从而提高坐果率、稳果率及单株产量水平。
Abstract:
In order to promote increase yield and stable yield of olive,we took three olive varieties including cultivars Ezhi 8,Douguo and Small Apple which have a large amount of flowers and a low yield as the materials,and studied the effect of flower and fruit thinning intensity of 1/4,1/3 and 1/2 on bearing and yield of the cultivars and compared the nutrient contents in leaves after thinning.The results showed that the 1/4 flower thinning at full-bloom could considerably increase yield per tree,the 1/2 flower thinning increased the fruit bearing percentage 15 days after blooming the most,the 1/4 fruit thinning increased the yield,bearing and single fruit weight the most.It showed a correlation with the contents of nitrogen,phosphorus,potassium,calcium and zinc in leaves which inferred that flower and fruit thinning could reduce the nutrient consumption of trees so as to increase fruit bearing and yield.
