5 planting densities of 180 000 holes/hm2 (D18.0), 225 000 holes/hm2 (D22.5), 270 000 holes/hm2 (D27.0), 315,000 holes/hm2 (D31.5),and 360 000 holes/hm2 (D36.0) were set for the mat grass variety Bancao 3. The optimum planting density of mat grass was selected by studying its effect on the yield of mat grass, the diameter of fresh grass, and the rate of withered shoot.The results showed that the planting density of Bancao 3 was 270 000 -315 000 holes/hm2, and the yield was high.The diameter of fresh grass and the tensile strength of stems of mat grass showed a gradually decreasing trend with the increase of planting density,while the rate of withered shoots of mat grass stems showed a gradually increasing trend with the increase of planting density, and the proportion of long grass stems showed a trend of first increasing and then decreasing with the increase of planting density. However the fresh grass diameter, withered shoot rate, proportion of long grass stems, and tensile strength of mat grass of D27.0 and D31.5 treatment were no significant difference from the corresponding optimal treatment. Therefore, considering the effects of comprehensive planting density on yield, fresh grass diameter, withered shoot rate, proportion of long grass stems, and tensile strength of mat grass, the suitable planting density of mat grass is 270 000- 315 000 holes/hm2.
Key words: mat grass; planting density; yield; quality
