摘要
与留茬 8cm和 4cm相比 ,留茬 6cm时多年生黑麦草株高净增量最小 ,密度最大。植物生长延缓剂可显著增加多年生黑麦草密度、降低株高、减少修剪次数。
Compared with 4 cm and 8 cm stubble, the 6 cm stubble of perennial ryegrass has the least increase of plant height and the densest tillers. Plant growth retardant treatments significantly increased tillers, decreased plant height and then reduced the mowing frequency and saved moving cost efficiently.
