前言日本的金弹每年开花三次。12月果实成熟时,第一次花果最大,品质最好。第二次花果也有商品价值,但第三次花果太小,失去商品价值。因此,对栽培者来说,增加第一次花量非常重要。与其他生长抑制剂不同,PP333表明能有效地减少柑桔的生长(Bausher 等,1984)。许多报道证实用 PP333作为增加金弹第一次开花量可能是一新的途径,虽然多数生长抑制剂在柑桔上应用没有明显效果。只是在花芽发育的不同阶段喷布。能增加某些落叶果树的开花量。本文的目的是研究 PP333对增加金弹树第一次开花量的效应。
Foreword Japan’s golden bomb blossoms three times a year. When the fruit is ripe in December, the first fruit is the largest and the quality is best. The second fruit also has the value of the commodity, but the third fruit is too small, losing the value of the commodity. Therefore, it is very important for growers to increase the first flowering. Unlike other growth inhibitors, PP333 has been shown to reduce citrus growth effectively (Bausher et al., 1984). Many reports confirm that PP333 may be a new route to increase the first flowering of golden shells, although most growth inhibitors have no significant effect on citrus. Just in different stages of flower buds sprayed. Can increase the flowering of some deciduous trees. The purpose of this paper is to investigate the effect of PP333 on increasing the first flowering rate of goldenrod.
