Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following in conjunction with the attached Figure 1-2 The present invention is further analyzed: figure 1 It adopts experiment 1 germination method of Bermudagrass seeds under variable temperature conditions, and the germination rate diagram of Bermudagrass seeds under variable temperature conditions. In the figure, ck means that Bermudagrass seeds have not undergone any treatment; soaking seeds means that Bermudagrass seeds are often soaked in 0.2% KNO3 solution for 7 days; It represents that bermudagrass seeds have been subjected to continuous light at 30°C for 3 days. figure 2 It adopts the germination method of Bermudagrass seeds under normal temperature conditions in Experiment 2. The germination rate of Bermudagrass seeds is shown under normal temperature conditions. In the figure, ck means that Bermudagrass seeds have not undergone any treatmen...

Abstract

The invention relates to a method for improving the cynodon dactylon seed germination rate. The method includes: 1. sunning cynodon dactylon seeds in a 30DEG C illumination incubator for 3d; 2. undera lighting condition, performing culture at 20DEG C for 12h, conducting culture at 30DEG C for 12h, and carrying out cycling with 24h as a period; and 3. conducting germination for 2-10d under the condition of step 2 so to obtain germinated cynodon dactylon seeds. The method provided by the invention has the characteristics of simplicity and feasibility, easy operation and obvious effect, can increase the germination rate of cynodon dactylon seeds from the 35% of untreated normal temperature culture to 95% after variable temperature treatment.

Description

technical field [0001] The invention relates to a method for improving the germination of bermudagrass seeds. Specifically, the physiological dormancy of bermudagrass is broken by continuously drying the seeds under 30°C light for 3 days, and then the germination rate can be increased to 95% by continuous light cultivation at a variable temperature of 20°C-30°C. Background technique [0002] Bermudagrass ( Cynodondactylon ), Poaceae ( Gramineae ) Bermudagrass is one of the most valuable and widely used warm-season turfgrass species for lawns. It is often used as lawn grass, pasture grass, urban greening or ecological grass for soil and water conservation. Bermudagrass has excellent characteristics such as drought resistance, flood resistance, heavy metal resistance, trampling resistance, and easy management. It is an ideal grass species for lawn planting and heavy metal pollution control. [0003] The lawn planting system is an ecological project integrating ecological c...
