Embodiment 1
[0019] Example 1 A method of using salicylic acid to improve the drought resistance of zoysia
[0020] Methods as below:
[0021] 1) Prepare a salicylic acid solution with a concentration of 0.5 mM, inject the solution into the sprayer, and spray the leaves;
[0022] 2) Select Zoysia seedlings for spraying, and the selected date is between May and June;
[0023] 3) Choose the weather without rain and spray for 3 days;
[0024] 4) Spray twice a day, once before 7:00 am and 6:00 pm;
[0025] 5) The amount of spraying is based on the fact that the leaves are wet but not dripping.
[0026] After 16 days of water control on the Zoysia lawn with the above treatment and no treatment, the aboveground biomass of the Zoysia grass sprayed with 0.5 mM salicylic acid solution was 2.83g / cm 2 , the aboveground biomass of Zoysia grass without spraying was 1.61 g / cm 2 ; The Zoysia subterranean biomass of salicylic acid solution spraying is 14.22g / cm 2 , the underground biomass of Zoysia ...
