避雨栽培对宿迁地区早熟桃生长发育及果实品质的影响

Effects of Rain Shelter Cultivation on Growth and Fruit Quality of Early-Ripening Peach in Suqian

以早熟桃品种‘金陵黄露’为试验材料,对其果实纵径、横径、裂果率、坐果率、产量及果实品质等指标进行分析,研究避雨栽培对宿迁地区早熟桃生长发育及果实品质的影响。结果表明,避雨栽培虽未改变果实的生长发育过程,但纵、横径比露地栽培增长要快。避雨栽培显著减少桃裂果现象,露地栽培裂果率20.3%,避雨栽培只有6.5%。果实内在品质方面,避雨栽培的果实硬度、可溶性固形物含量、总糖含量、VC含量均显著高于对照,总酸含量显著低于对照,单果重与露地栽培无明显差异。此外,避雨栽培显著提高了桃果实的坐果率和产量,666.7m2产量为3 600 kg,比露地栽培提高28.6%。

Using the early-ripening peach variety Jinlinghuanglu as material,the effects of rain shelter cultivation on growth and fruit quality of peach were explored through investigating the fruit vertical diameter,transverse diameter,dehiscent fruit rate,fruit setting rate,yield,fruit quality and etc. The results showed that rain shelter cultivation did not change the growth and development process of fruits,but the vertical and transverse diameter grew faster than those of open field cultivation. Rain shelter cultivation significantly reduced the dehiscent fruit phenomenon with the dehiscent fruit rate of only 6. 5% compared with 20. 3% in open field. The fruit hardness,contents of soluble solids,total sugar and VC were significantly higher than those in open field. However,the total acid content was significantly lower than that in open field. There was no significant variation on single fruit weight. Besides,rain shelter cultivation significantly improved the fruit setting rate and yield. The fruit yield of rain shelter cultivation achieved 3 600 kg per 666. 7m2,which increased by 28. 6% than that in open field.
