Abstract
Taking rice variety of Song-122 as material,the field plot experiment was carried out to study effects of wide-narrow row spacing cultivation on growth and yield of rice.The results showed that tiller number,panicles number and grain weight were reduced in treatment of 70 cm-20 cm wide-narrow row spacing cultivation,these lead to its decrease in yield.There was no significant difference in the development and yield formation in treatment of 50 cm-20 cm wide-narrow row spacing cultivation,and efficiency of transplant rice seedlings was increased,environment in the fields was improved.
