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 ...

Abstract

The invention relates to a method for improving drought resistance of zoysia by utilizing salicylic acid. The adopted technical scheme is as follows: adopting a salicylic acid solution with the concentration of 0.1-1mM to perform foliage spraying; and spraying during the seedling stage of the zoysia, wherein the dates are often selected between May and June, the rainless weather is selected, the spraying time is 2-4 days, the spraying is performed 2-4 times per day, the spraying is often performed before 8:00am and after 5:00pm, and the spraying amount meets the standard of humidifying leaf blades without water dropping. By adopting the method disclosed by the invention for treating the zoysia, the drought resistance of the zoysia can be significantly improved; and furthermore, the method has the characteristics of simple process steps, easiness in operation, no production of secondary pollution and low cost, and is convenient for large-area treatment.

Description

technical field [0001] The invention relates to a method for improving the drought resistance of zoysia, in particular to a method for improving the drought resistance of zoysia by spraying salicylic acid solution. Background technique [0002] Zoysia has strong adaptability to soil. Zoysia is resistant to barrenness, trampling, drought, saline soil, and low pruning, and has a wide range of application values ​​in various lawn establishments. In some countries such as China, Japan, South Korea, North Korea and the United States, it is widely used in the open green spaces of cities and parks, the establishment of sports field lawns, and as soil and water conservation plants. It is an excellent warm-season turfgrass recognized worldwide. [0003] In urban areas where water resources are increasingly scarce, the amount of water required for zoysia lawn irrigation has become a practical problem that is difficult to solve, which limits the development of urban green spaces to a ...
