调节剂输液滴干对桂味荔枝果实产量及品质的影响

Effects of Growth Regulator Transfusion Following Trunks on The Yield and Quality of Guiwei Litchi

桂味是广西最重要的优良荔枝品种,为了探索控制桂味冬梢的方法,笔者进行了调节剂虹吸输液滴干试验。结果表明,乙烯利加多效唑生物肥混合液在花芽生理分化期输液滴干显著抑制了冬梢生长,提高了产量。抽生冬梢、冬梢率、复叶数、小叶数比对照减少了81.31%、58.40%、71.23%;果穗数量、单穗重、单株产量分别提高了428.77%、26.44%和568.37%。调节剂输液滴干还提高了果实的品质,果实纵径、横径、侧径分别增加了7.19%、8.58%、8.05%;可溶性固形物增加了4.90%;可食率增加了11.48%,显著高于对照组。

Guiwei litchi is the most important good varieties in Guangxi, the trial of plant growth regulator transfusion following trunks was carried out for exploring the methods of controlling the winter shoots. The results were as follows: transfusion following trunks of mixed liquor of biological fertilizer with ethephon and paclobutrazol can inhibition growth of winter shoots and increase the yield. The winter shoots, rate of winter tip, number of compound leaf and leaflet was decreased by 81.31%, 81.31%, 71.23%.The number of ears,single ear weight and single plant yield increased by 428.77%,26.44% and 568.37% respectively. The plant growth regulator transfusion following trunks improved fruit quality, the vertical diameter, horizontal diameter and side diameter of the fruit were increased by 7.19% 8.58%, 8.05% respectively, the content of the soluble solids was increased by 4.90%, and the edible rate was increased by 11.48%, significantly higher than that in the control group.
