除草剂封地对高粱生长发育和籽粒产量的影响
Effect of the Pre-emergence Treatment Using Herbicide on Growth Flowering Stage and Biological Yield of Sorghum
摘要
Abstract
This study selected Liaoza 37,Liaoza 19,Liaotian 1 and Liaonian 3 as the test material,using At-razine and Metolachlor for the pre-emergence treatment,measured the plants height, stem diameter,dry weight,flowering stage and yield,analyzed the effect of the pre-emergence treatment for the sorghum.The re-sults showed that the pre-emergence treatment using herbicide influenced the vegetative growth of sorghum.The effect of the vegetative growth for Liaoza 37,Liaoza 19 and Liaonian 3 had weaken when the reprductive growth and vegetative growth been all last.But the yield of these hybrids had no significance difference between the pre-emergence treatment and CK.The pre-emergence treatment had a great effect on Liaotian 1.So,the planter should select suitable pre-emergence treatment.关键词
