Abstract:

【Objective】The research aims to study the effects of different drip irrigation amounts on the storage quality of Korla fragrant pear fruit, so as to provide reference for the study of water-saving irrigation and storage time of the fruit.【Methods】The 5-year-old trunk-shaped Korla fragrant pear tree was used as the test material, and 5 drip irrigation gradients were set. At the mature stage, 50 fruits were randomly picked in each group and stored for 0,10,20,30,40 d to determine the fruit quality.【Results】The fruits treated with W1 (5,460 m3/hm2) were not resistant to storage and all rotted after 40 days of storage. The fruit treated with W5 (7,140 m3/hm2) had the best storage quality. After 40 days of storage, the content of soluble protein in peel was the highest, which was 2.37 mg/g, the content of VC in peel was the highest, which was 2.36 mg/100g, and the content of soluble sugar in pulp was the highest, which was 11.6 %. The comprehensive evaluation of principal component analysis showed it ranked the first.【Conclusion】The fruit quality of Korla fragrant pear is the best after 40 days of long-term storage under the drip irrigation amount of W5 (7,140 m3 / hm2). When the drip irrigation amount was too small, it was not conducive to the improvement of the storage quality of the pear.

摘要:

【目的】研究不同滴灌灌水量对新疆库尔勒香梨果实贮藏品质的影响,为筛选香梨节水灌溉量及提升其贮藏品质提供参考依据。【方法】以5年生主干形香梨树为试材,设置5个滴灌灌水量梯度W1(5 460m3/hm2)、W2(5 880m3/hm2)、W3(6 380m3/hm2)、W4(6 720 m3/hm2)和W5(7 140 m3/hm2),成熟期各组随机采摘50个果实,分别贮藏0、10、20、30和40 d,测定果实品质。【结果】W1(5 460 m3/hm2)处理果实不耐贮藏,在贮藏40 d时全部腐烂;W5(7 140 m3/hm2)处理的果实贮藏品质最佳,贮藏40 d时,果皮可溶性蛋白质含量最高,为2.37 mg/g,果皮VC含量最高,为2.36 mg/100g,果肉可溶性糖含量最高,为11.6%,主成分综合评价排名第一。【结论】W5(7 140 m3/hm2)滴灌灌水量下香梨果实贮藏40 d品质最佳,滴灌灌水量过少时不利于提升香梨果实贮藏品质。
