Effects of Lacquer-tree Nutrient Solution on Lacquer-tree Growth and Lacquer Quality

In order to improve the quality of the raw lacquer,we sprayed the lacquer tree nutrient solution with mineral elements(P,K,Cu,Mg,etc.) and plant growth regulators on the Maoba lacquer trees,then observed the growth of lacquer tree and tested the quality of raw lacquer.The results showed as follows:The lacquer trees in the treatment group flourish,barks are thicker,and the time of leaf shedding was postponed about half a month,with no side effect;the raw lacquer from the treated lacquer trees contained more urushiol,laccase and gum;the organoleptic index of the raw lacquer from the treated lacquer trees improved significantly;the surface drying time of raw lacquer from the treated lacquer trees was shortened.The main mechanism is that the lacquer tree nutrient solution changed the nutrient condition and improved metabolism.The nutrient solution can promote lacquer-tree and improve lacquer quatity.
