有机无机复混肥对无核白葡萄产量和果实品质的影响

【目的】研究不同配比的有机无机复混肥对吐鲁番无核白葡萄产量、品质的影响,为该地区无核白葡萄的科学施肥提供理论技术依据。【方法】材料为11年生的无核白葡萄,实验设4个因素,16个处理,测定产量和几项品质指标,确定效果最佳的有机无机复混肥配方。【结果】施用不同配比的有机无机复混肥时,处理8～11的单产高于其它处理,其中处理10和11的产量显著高于其它处理,而处理1和16的产量相对较低;处理9～12改善无核白葡萄品质的效果较突出,尤其是配方10和11的效果最佳。施用处理10和11复混肥后,无核白葡萄果粒百粒重、纵横径、VC、可溶性糖和糖酸比都显著高于其它配方,而可滴定酸含量显著低于其它处理,硬度也保持较高的水平。【结论】试验设置的有机无机复混肥配比配方10和11能显著提高无核白葡萄的产量和品质,在该地区具有推广价值。

Effect of Organic-inorganic Compound Fertilizer on the Yield and Quality of Thomson Seedless Grape

【Objective】 To study effects of different proportions organic-inorganic compound fertilizer on yield and quality of Turpan Thompson seedless grape,to provide theoretical and technical basis for scientific fertilization on Thompson seedless grape in this area.【Method】 The 11-years old Thompson Seedless grape was used as test materials.Four factors and 16 treatments were set in this experiment,and yield and several quality indexes were measured to determine the best formula of organic-inorganic compound fertilizer.【Result】After applying the different proportions of organic-inorganic compound fertilizer,the yield of 8-11 mus of proceed treatment was higher than that of the field by other treatments,among which the yields by treatment 10 and 11 were significantly higher than others,and the yields by treatment 1 and 16 were relatively lower;Treatments 9-12 have remarkable improvement effects on quality of Thompson seedless grapes;among them treatments 10 and 11 were the best formulas.After using fertilizer treatments 10 and 11,the 100-grain weight,grain length and width,Vc content,soluble sugar and sugar-acid ratio of Thompson seedless grape were significantly higher than those by other formulations,and titration acid content was significantly lower than that by other treatments,while the hardness stayed at a high level.【Conclusion】The organic-inorganic compound fertilizer formulations 10 and 11 could significantly increase yield and quality of Thompson seedless grape,which have more popularization value in the area.
