甲壳素对文心兰营养元素的影响
The Effect of Different Concentrations of Chitin on the Nutrient Contents of Oncidium
摘要
Abstract
[Objective ]The aim was to study the effect on the nutrient elements content of Oncidium at the different concentrations of chitin(0、 500.,1 000,1 500 ,,2 000 jxg/L). [Method] Under nutritional starvation,different concentrations of chitin were applied to Oncidium,and the differences of nutrient elements content of Oncidium leaf blades and peusudobulbs was determined. [ Result ] When the concentration of chitin was 1 500 (Ag/m,the nutrient elements content of N,P,Fe,Mn in Oncidium leaf blades was highest,especially the nutrient elements content of Fe,Mn was significantly higher than other treatment at different concentrations. In pseudobulb of Oncidium,the N、K、Ca,Mg content was highest. Among them, K^CaNMg content was significantly higher in the treatment of chitin at 1 500 u^j/L than other treatment at different concentrations. Besides, the Zn content difference in leaf blades was not significant,but the Zn content change in pseudobulb was most significant,the higher concentration of chitin applied to Oncidium, the higher content of Zn content in pseuobulb. [ Conclusion ] Under nutritional starvation, different concentrations of chitin had significant effect on the nutrient elements of Oncidium leaf blades and peusudobulbs,but the effect on nutrient elements content between leaf blades and pseudobulb were inconsistent,and the inconsistency was extremely prominent.关键词
