不同施肥处理对火龙果产量和品质的影响

Effects of different fertilization treatment on the yield and quality of pitaya fruit

【目的】通过施用不同肥料类型,并结合不同施肥方式,探寻可提高火龙果产量及提升果实品质的最优肥料类型及施肥技术组合。【方法】以盛果期果龄的金都1号品种为材料,将复合肥采用常规土壤施肥与采用滴灌施肥进行对比试验。【结果】等同肥料用量及配比条件,采用水溶肥滴灌施比肥料常规土施每667m^2增产190.1kg,增长11.2%;挂果数和成果数分别增加589个和776个,平均单果重0.45 kg,增加0.04 kg,产量商品果率增加3.8%。【结论】在等同的施肥水平和配方条件下,复合肥采用滴灌施用技术,比肥料常规土壤施肥方法可提高火龙果产量、质量和商品性,并促进春梢早萌发,增加座果及成果的数量,较好地培养健康枝条的发育。

【Objective】By applying different fertilizer types and combining with different fertilization meth⁃ods,the optimal fertilizer types and the combination of fertilization techniques can be explored to improve the yield and quality of pitaya fruit.【Method】Adopt the pitaya variety of Jindu No.1 of full productive age as the material,compare the compound fertilizer which the group applied conventional soil fertilization,while the other group drip irrigation fertilization.【Result】With the same fertilizer dosage and proportioning conditions,the yield per 667m2 was increased by 190.1 kg,by 11.2%the number of fruit hanging and the number of results increased by 589 and 776,respectively,with an average fruit weight of 0.45 kg,an in⁃crease of 0.04 kg,and the yield of commercial fruit increased by 3.8%.【Conclusion】Under the same fertil⁃ization level and formula condition,the compound fertilizer adopts drip irrigation application technology,which can improve the yield,quality and commodity of the fruit,promote the early germination of spring shoots,increase the number of fruit and achievements,and better cultivate the development of healthy branches.
