【摘要】 以‘黄冠梨’为试验材料，以清水作为对照，采用叶片喷施的方法，研究4种不同植物生长调节剂组合对果实生长和品质的影响。结果表明，4种不同植物生长调节剂组合都能显著提高‘黄冠梨’的单果重，较对照提高36.71%～49.01%。钱江利果灵两个组合能显著提高果型指数，均提高6.45%。钱江凯胜两个处理和钱江利果灵360倍+14-羟芸2 500倍液能显著提高可溶性固形物含量0.92%～1.34%。钱江利果灵两个组合和钱江凯胜1 250倍+14-羟芸2 500倍液能显著提高可滴定酸含量0.03%～0.05%。更多还原

【Abstract】 Using ’Huangguan pear’ as the experimental material and clear water as the control, the effects of four different plant growth regulators combinations on the growth and quality of fruit were studied using leaf spraying method.The results showed that four different combinations of plant growth regulators could significantly increase the single fruit weight of ’Huangguan pear’, with an increase of 36.71%～49.01% compared to the control. The two combinations of Qianjiang Liguoling can significantly improve the fruit type index, both increasing by 6.45%. The two treatments of Qianjiang Kaisheng and Qianjiang Liguoling 360 times +14-hydroxyyun 2 500 times solution can significantly increase the soluble solid content by 0.92% ～1.34%. The combination of Qianjiang Liguoling and Qianjiang Kaisheng 1 250 times+14-hydroxyyun 2 500 times solution can significantly increase the titratable acid content by 0.03%～0.05%.更多还原
