| Abstract: | Years of surveys and analysis preliminarily showed that the suitable sampling time for nutritional diagnosis of Vanilla planifolia was between October and November with the sampling position located at the 7th and 8th leaves under terminal leaf. The indexes of nutritional diagnosis for Vanilla Planifolia are both the suitable range and the specific value of major nutrient balance. The suitable range of vanilla nutrition content are N 2. 15 %-2. 40 %,P 0. 43 %-0. 50 %,K 2. 70 %-3. 20 %,Ca 3. 60 %-4. 2 %,andMg 0. 35 % -0. 70 %. The suitable range of specific value of major nutrient balance is N/P 4. 99 -5. 33,P/Ca 0. 108-0. 114,Mg/P 1. 40-1. 54,K/P 6. 00-6. 46,Mg/Ca 0. 154 0. 173. The index for trace elements is not determined yet. |
