播种量·修剪频率和留茬高度对匍匐翦股颖果岭成坪时间的影响

Effects of Sowing Quantity,Mowing Frequency and Cutting Height on Turf Grass Growing Time of Agrostis stolonifera L.

[目的]为匍匐翦股颖的成坪管理提供指导。[方法]以匍匐翦股颖A1+A4的混播品种为材料,采用不同播种量、修剪频率和留茬高度3因素3水平的正交试验设计,研究各因素对匍匐翦股颖果岭成坪时间的影响。[结果]播种量、修剪频率和留茬高度对匍匐翦股颖果岭的成坪时间都有显著影响,其中,播种量的影响最显著,其次为修剪频率。播种量为10 g/m2时,成坪时间最短,效果最好;修剪频率为1次/d时,效果最好;留茬高度为5 mm时,效果最好。[结论]在不考虑3个因素交互作用的情况下,匍匐翦股颖的播种量为10g/m2、修剪频率为1次/d、留茬高度为5 mm时,其果岭的成坪时间最短,效果最好。

[Objective] The aim was to provide the guidance for the forming turf management of Agrostis stolonifera L.[Method] With mixed sowing variety A1＋ A4 of A.stolonifera as material,the orthogonal test of 3 factors（sowing quantity,mowing frequency and cutting height） with 3 levels was taken to study the effect of factors on the turf forming time of A.stolonifera.[Result] The sowing quantity,mowing frequency and cutting height all had significant effect on the turf forming time of A.stolonifera.The effect of sowing quantity was the biggest and the second was mowing frequency.When the sowing quantity was 10 g/m2,the turf forming time was the shortest and the effect was the best.When the mowing frequency was 1 time/d,the effect was the best.When the cutting height was 5 mm, the effect was the best.[Conclusion] In the condition of without interaction effects of 3 factors,when the sowing quantity of A.stolonifera was 10 g/m2,the mowing frequency was 1 time/d and the cutting height was 5 mm,its turf forming time was the shortest and the effect was the best.
