1983年我们对四川柑桔的施肥现状与营养问题进行了较为广泛的调查。从调查资料概略看出,当前全省各地柑桔园的施肥管理水平在不同地区之间很不平衡,即使同一地区,在施肥时期和次数,以及肥料种类与用量上也各不相同。不少柑桔园缺肥或施肥不当的现象仍较为严重。为提高柑桔的施肥管理技术,促进我省柑桔生产发展,根据调查情况,提出以下几点粗浅意见,供参考。 In 1983, we conducted a more extensive investigation on the status quo and nutrition of fertilizers in Sichuan citrus. According to the survey data, the fertilization management levels of citrus orchards in various parts of the province are very uneven among different regions. Even in the same area, the fertilization period and frequency, and the type and amount of fertilizers also vary. Many citrus orchard lack of fertilizer or inappropriate phenomenon is still more serious. In order to improve the fertilization management technology of citrus and promote the development of citrus production in our province, according to the investigation, the following opinions are put forward for reference.
