一、多效唑对花生的调控效果 (一)促进根系发育。花生喷施多效唑后,根系性状均优于对照组。其主根长、根颈粗、侧根数和健壮根均比对照增长16.2％、21.6％、18.6％和38.4％,病根数则比对照减少38.6％。 (二)控长明显,增加分枝。喷施多效唑的花生株高比对照组的主茎高和侧枝长分别降低4.3～8.1厘米和5.2～9.7厘米;单株侧枝数较对照的增加0.3～2.5个;单株有效分枝比对照组增加0.4～1.3个。

First, the effect of paclobutrazol on peanut control (A) to promote root development. Peanut sprayed paclobutrazol, the root traits are better than the control group. The main root length, root girth, number of lateral roots and robust roots increased by 16.2%, 21.6%, 18.6% and 38.4% respectively compared with the control. The number of diseased roots was reduced by 38.6% compared with the control. (B) control long obvious, increase branches. The height of peanut plants sprayed with paclobutrazol was 4.3 ~ 8.1 cm and 5.2 ~ 9.7 cm lower than that of the control, respectively. The number of collateral per plant was increased by 0.3 ~ 2.5 compared with the control. The effective branching per plant was higher than that of the control Increase 0.4 ~ 1.3.
