脐橙是世界著名的柑桔良种,我省早在1913年开始引种。目前栽培的脐橙主要有华盛顿、汤姆逊、罗伯逊等品系(以下简称华脐、汤脐、罗脐),在黄岩应用枳或构头橙等为砧木,产量很低,常表现初生树结果尚可,树龄稍大后,往往花而不实、少产甚至无收,因此,现已很少栽种。 1979～1981年,调查了我所本地早砧(以下简称本砧)脐橙的生产性能,发现用本砧或高接作中间砧(基砧为构头橙),均有较好的生产性能。 现将调查结果,简述如下。
Navel orange is a world famous citrus varieties, as early as 1913 in our province introduced. Currently cultivated navel oranges are mainly Washington, Thomson, Robertson and other strains (hereinafter referred to as Hua na, soup umbilical, Lo na), Huangyan application of trifoliate orange or dichroma orange as the rootstock, the yield is very low, When the tree is slightly older, it is often spent rather than real, with few or no harvests. Therefore, it is rarely planted. From 1979 to 1981, we surveyed the production performance of navel oranges from our local anvil (hereinafter referred to as “anvil”) and found that both the anvils and high intermediate grasses (base anvils) have good performance. The survey results are summarized below.
