摘要

以每公顷约1500棵密度种植的4年生“炳”甜樱桃树，一次施用多效唑(Cultar)作为土壤淋水(SD)，将1l多效唑水溶液倒入树干周围的沟中，或作为行侧淋水(RSD)，将1l多效唑溶液分为两次剂量，每次0.5 l，并倒入位于除草剂带两侧的两个沟中。或一种树皮涂漆应用程序(BP)，其中20厘米宽的树皮带用多氯丁唑溶解在100%表面活性剂WK中刷涂。在所有三种情况下，每平方厘米树干横截面积使用标准剂量15毫克多效唑。SD树和RSD树在施药后69 d出现了枝条生长抑制的迹象，而BP树在施药后约12 d出现了一些抑制。SD和RSD均降低了坐果量，但BP不降低。施用年度多效唑对产量无显著影响。两年期累计收益率最高的一年是2008年。

EFFECT OF METHOD OF APPLICATION OF PACLOBUTRAZOL IN HIGH-DENSITY SWEET CHERRY ORCHARDS ON TREE PERFORMANCE AND APPARENT SOIL RESIDUE

SummaryFour year old `Bing' sweet cherry trees planted at a density of ca. 1500 trees per ha were treated once with paclobutrazol (Cultar) applied as soil drench (SD) where 1 l of paclobutrazol aqueous solution was poured into a furrow around the tree trunk, or applied as a row-side drench (RSD) where 1 l of paclobutrazol solution was divided into two doses of 0.5 l and poured into two furrows located on both edges of the herbicide strip, or a bark painting application (BP) where a 20 cm wide tree bark band was brush-painted with paclobutrazol dissolved in 100% `Surfactant WK'. A standard rate 15 mg paclobutrazol per cm2 of tree trunk cross-sectional area was applied in all three cases. The SD and RSD trees showed signs of shoot growth inhibition 69 d after application, about 12 d before some inhibition was seen on the BP trees. Fruit set was reduced by both the SD and RSD but not by the BP. Yields were not influenced by paclobutrazol in the application year. The highest two-year cumulative yields were ob...

期刊介绍： The Journal of Horticultural Science and Biotechnology is an international, peer-reviewed journal, which publishes original research contributions into the production, improvement and utilisation of horticultural crops. It aims to provide scientific knowledge of interest to those engaged in scientific research and the practice of horticulture. The scope of the journal includes studies on fruit and other perennial crops, vegetables and ornamentals grown in temperate or tropical regions and their use in commercial, amenity or urban horticulture. Papers, including reviews, that give new insights into plant and crop growth, yield, quality and response to the environment, are welcome, including those arising from technological innovation and developments in crop genome sequencing and other biotechnological advances.
