通常,新建枣园幼树当年不抽新梢,有时进入第二年也不发枝,挂果期要延迟到第三、四年。这对提早结果、早收益是一大限制。为此,1988年清明节前,我们对1987年栽植(1年生苗)的0.1ha 枣园幼树平了一部分茬,并设立了对照。翌年秋季调查,发现平了茬的幼树高、径生长普遍高于未平 Usually, new jujube seedlings do not shoot new shoots that year, and sometimes do not start the second year into the branches, hanging fruiting period to be delayed until the third and fourth years. This is an early result, early gains are a big restriction. To this end, before the Ching Ming Festival in 1988, we planted part of the 0.1 ha jujube seedlings planted in 1987 (one-year-old seedlings) and set up a control. The following autumn survey found that stubble sapling height, diameter growth generally higher than the flat
