【摘要】 通过对引进短季棉控制棉太金不同施用量,以期达到塑造理想株型、简化栽培并构建适于机械采收的早熟棉群体的目的。结果表明,棉太金对棉花生长具有显著的调控作用,随棉太金单位面积施用量增大,叶面积、果枝数、总果节数、单株成铃数减少;株高、单株干质量、果枝长度、始节位、始节高度、铃重、衣分和小区产量下降。更多还原

【Abstract】 The experiment set different spraying amounts of "Miantaijin" to realize the simplified cultivation and Construction the short season cotton group for mechanical harvesting.The results showed that-the "Miantaijin" had a good regulation on Cotton Growth.Increasing the amount of Spraying per unit area,leaf aera.the number of fruiting branches,total number of fruit nodes and the number of bolls per plant were reduced;The height,dry weight,branch length,first fruiting branch node,the height of the first fruiting branch node,the boll seed cotton weight,lint percentage rate and cotton yield were declined.更多还原
