近年来,广东各地把深翻压绿(深翻改土)作为柑桔山地栽培中最基本的关键技术措施之一,认为它能逐步改良根际土壤,培养一个生长深、广、密的强大根群,为山地柑桔的丰产稳产、长寿创造好的基础。针对湛江地区橙园开展深翻压绿中提出的主要问题,1964～1966年原广东农科院柑桔研究所与原红湖农场(今八师七团)协作,在五年生化州橙园对深翻压绿的效果、时期、方法等方面进行了若干项目的实验研究。本文就是这些工作的初步总结。我们认为:它在山地柑桔园深翻压绿问题上提供了一些初步的理论根据。
In recent years, Guangdong Province, the deep plowing green (deep turn to change soil) citrus mountain cultivation as the most basic one of the key technical measures, that it can gradually improve the rhizosphere soil, cultivate a deep growth, wide, dense strong Root group, for the mountain citrus yield and long-life to create a good foundation. In response to the major problems raised in the orange orchards in Zhanjiang region, the Citrus Research Institute of Guangdong Academy of Agricultural Sciences, 1964 ~ 1966, cooperated with the former Red Lake Farm (now 7 divisions and 7 groups) On the deep plowing green effect, period, methods and other aspects of a number of experimental projects. This article is a preliminary summary of these efforts. In our opinion, it provides some preliminary theoretical evidences on the problem of deep plowing of mountain citrus orchards.
