摘要
对海南省香草兰主要种植区的香草兰种植园的植株样品进行了测试分析。结果表明:香草兰种植园植株养分缺乏严重,植株N、P、K、Ca、Mg缺乏的香草兰园分别占全省的62.07%、100%、6.90%、93.10%、79.31%,其中P、Ca缺乏最严重;且各养分之间比例严重失衡,N/P、P/Ca、Mg/P、Mg/Ca、K/P严重不平衡的香草兰园分别占全省的100%、93.1%、82.75%、82.76%、100%。由于香草兰是典型的喜P、Ca作物,因此建议各种植园加大P、Ca肥的投入,同时增施N、Mg肥,使各养分都达到最适香草兰生长的浓度,同时使各养分之间达到平衡。
The samples of main Vanilla planifolia Andrews-growing areas in Hainan Province were tested. It was reveald that the deficiency of nutrients of Vanilla planifolia Andrews plants was serious, and the percentage with nutrient deficiency of N, P, K, Ca, Mg in all plantations was 62.07%, 100%, 6.90%, 93.10%, 79.31%, respectively. The deficiency of P and Ca was among the most serious. The serious imbalance of nutrients was observed at the same time, and the percentage with serious imbalance of N/P, P/Ca, Mg/P, Mg/Ca, K/P in all plantations was 100%, 93.1%, 82.75%, 82.76%, 100%, respectively. As P and Ca is typically required by Vanilla planifolia Andrews, more P and Ca with additional N and Mg should be applied in all Vanilla planifolia Andrews plantations to best balance its nutrition uptake.
