隔年结果是果树栽培中的一个老问题,栽培者都不希望出现隔年结果。虽然在采用现代品种和栽培技术之后,这一问题显得不那么尖锐,但隔年结果仍普遍存在。尤其是某些具体隔年结果习性的优良品种,对现代栽培家来说是一种挑战。花芽的形成是核心问题,它受下列一系列因子的影响,如座果和果实生长、枝条类型、砧木、修剪和生长调节剂。将果园中二分之一的树进行全部疏花,可能每年至少得到二分之一的产量。虽然不能获得全部的产量,但这对于家庭果园似乎是一种实际可行的办法。生长调节剂的应用具有最好的前景,它在大年能促进花芽分化,在小年能减少花芽分化。这些物质可在疏除过多的果实之后或甚至不疏果的情况下加以施用。
The next year’s result is an old problem in fruit tree cultivation, and the growers do not want the second year’s results. Although the problem is less acute after the introduction of modern varieties and cultivation techniques, the results of the following year are still prevalent. In particular, the fine varieties of some specific year-by-year habits are a challenge to modern growers. The formation of flower buds is a central issue that is influenced by a number of factors such as fruit and fruit growth, shoot types, rootstocks, trim and growth regulators. Full flowering of one-half of the trees in the orchard may yield at least one-half of the yield each year. Although not fully available, this seems to be a practical solution for family orchards. The application of growth regulators has the best prospects, it can promote flower bud differentiation in the new year, can reduce flower bud differentiation in the small year. These substances can be applied after excessively thinned fruit or even fruitless.
