摘要:

以杂柑阳光1号为试验材料,在初花期(4月初)、盛花期(4月中旬)和果实膨大期(7月中旬)喷施植物生长调节剂和叶面肥,探究不同生长期喷施植物生长调节剂和叶面肥对阳光1号果实裂果和品质的影响。结果表明,与对照(喷施清水)相比,各处理均能显著(p<0.05)降低阳光1号的裂果率,并显著增加单果重。T4处理[初花期喷施30 μg·L-1 6-苄氨基嘌呤(6-BA)+50 μg·L-1赤霉素(GA3),盛花期喷施100 μg·L-1 GA3,果实膨大期喷施800倍钙镁硼锌铁]的果皮厚度显著降低。T3(初花期喷施30 μg·L-1 6-BA+50 μg·L-1 GA3,盛花期喷施100 μg·L-1 GA3,果实膨大期喷施500倍磷酸二氢钾)和T4处理能够显著提高果实色泽指数(CCI)。除T7处理(果实膨大期喷施200 μg·L-1 GA3+500倍磷酸二氢钾)的固酸比降低外,其他处理果实的固酸比和维生素C含量与对照无显著差异。主成分分析表明,T3处理的综合得分最高,整体效果最好,生产中可以参考使用。

Abstract:

Using hybrid citrus Yangguang 1 as the experimental material,plant growth regulators and foliar fertilizers were sprayed in the early flowering period(beginning of April),full flowering period(mid-April)and fruit enlargement period(mid-July). The effects of spraying plant growth regulators and foliar fertilizers at different growth periods on fruit cracking and quality were investigated. The results showed that compared with the control,each treatment could significantly (p<0.05)reduce the fruit cracking rate of Yangguang 1 and significantly increase the single fruit weight. The peel thickness of T4 treatment [spraying 30 μg·L-1 6-benzylaminopurine (6-BA)+50 μg·L-1 gibberellic acid (GA?) at the early flowering period, spraying 100 μg·L-1 GA3 at the full flowering period,and spraying 800 times Ca-Mg-B-Zn-Fe fertilizer at the fruit enlargement period] was significantly reduced. T3 (spraying 30 μg·L-1 6-BA+50 μg·L-1 GA? at the early flowering period, spraying 100 μg·L-1 GA3 at the full flowering period,and spraying 500 times potassium dihydrogen phosphate at the fruit enlargement period)and T4 treatments improved the color contribution index of fruit. Except for the decrease of solid-acid ratio of T7 treatment (spraying 200 μg·L-1 GA?+500 times potassium dihydrogen phosphate at the fruit enlargement period),the solid-acid ratio and vitamin C content of other treatments had no significant difference compared with the control. Principal component analysis showed that T3 treatment had the highest comprehensive score and overall effectiveness,which can be referenced for practical production.
