广东省山区猕猴桃配方施肥技术的研究

Study on Formula Fertilization Techniques for Kiwifruit in Mountain Areas of Guangdong Province

广东省是我国大陆最南端的猕猴桃生产基地,也是北半球猕猴桃最早上市的产区。本试验在广东省和平县三个猕猴桃果场对"武植3号"猕猴桃进行氮、磷、钾肥料配施试验,比较了不同的配方施肥方案对三个猕猴桃果场果实的农艺性状、品质和产量的影响。结果表明,4、5、9号和10号的配方施肥对猕猴桃的单果重、果肉果皮比例和单株结果数有较大的提高;5号的配方施肥对猕猴桃的6项品质指标有明显提高作用;产量统计结果显示,4、5和9号配方施肥对产量增加明显。总的来说,5号施肥方案对于果形、品质和产量都有一定的提高作用,因此,本试验建议每667m^2种植60株猕猴桃的氮、磷、钾肥用量分别为90kg、120kg、150kg。本试验结果对广东省山区猕猴桃科学施肥技术提供了一定的参考依据。

Guangdong province is the southern most production base of kiwifruit in China's Mainland.It is also the earliestproducing area of kiwifruit in the northern hemisphere.In this experiment,in the three kiwifruit orchard of Heping county,N P K fertilizer experiment on"Wuzhi No.3"kiwifruit were studied,and compared the effect of different fertilizationscheme on kiwifruit agronomic traits,yield and quality.The results showed that No.4,5,9and10formula fertilizationincreased the single fruit weight,the percentage of between fruit flesh.and pericarp,and fruit number per plant.Formulafertilization of No.5could obviously improve the6quality indexes of kiwifruit.Yield statistics showed that No.4,5and9formula fertilization increased yield obviously.In general,the No.5fertilization scheme could improve fruit shape,qualityand yield.Therefore,the amounts of nitrogen,phosphorus and potassium fertilizer in kiwifruit per667m2were respectively90kg,120kg,150kg,in which60kiwis were planted.The results of this experiment provided certain guidance for thescientific fertilization of kiwifruit in Guangdong mountain area.
