Embodiment 1

[0019] Example 1 A method of improving the drought resistance of zoysia

[0020] Methods as below:

[0021] 1) Prepare CaCl with a concentration of 10mM 2 Solution, the solution is injected into the sprayer for foliar spraying;

[0022] 2) Select Zoysia seedlings for spraying. Between May and June, choose rainless weather and spray for 3 days; spray twice a day, before 7:00 am and after 6:00 pm respectively Spray once;

[0023] 3) The amount of spraying is based on the fact that the leaves are wet but not dripping.

[0024] 10 mM CaCl 2 The aboveground biomass of Zoysia grass sprayed by solution was 2.38 g / cm 2 , the aboveground biomass of Zoysia grass without spraying was 1.33 g / cm 2 ;CaCl 2 The underground biomass of Zoysia grass sprayed by solution was 11.06g / cm 2 , the underground biomass of Zoysia grass without spraying was 4.67 g / cm 2 . Foliar spray of CaCl 2 Significantly increase the yield of zoysia under drought conditions and enhance the drought resistance...

Abstract

The invention relates to a method for improving drought resistance of zoysia. The adopted technical scheme is as follows: adopting a CaCl2 solution with the concentration of 5-20mM to perform foliage spraying; and spraying during the seedling stage of the zoysia, wherein 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 grass, particularly by spraying CaCl 2 Solution method for improving drought resistance of zoysia. 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 certain ext...
