万载县地处赣北,冬季气温低,年极端低温≤-7℃的气温平均8年左右一遇,≤-9℃的低温平均12年左右一遇,成为该县发展柑桔的一大障碍。目前全县柑桔面积共有1.2万余亩,冬季常受低温的影响,尤其幼龄柑桔常不能安全越冬。为了避免与减轻柑桔的冻害,生产单位初步摸索出冬季在桔园里,特别是在幼龄桔园栽种蔬菜作物,可以起到防冻的效果。现将有关情况介绍如下,供参考。
Wanzai County is located in the north of Jiangxi Province, with low winter temperatures and extreme low temperature ≤-7 ℃. The temperature is about 8 years on average.
