摘要
以松-122水稻品种为试材,通过田间小区试验,对水稻在不同宽窄行配置下的生长发育及产量形成进行了研究。结果表明:70 cm-20 cm宽窄行距配置使水稻的分蘖数、穗数、粒重降低,导致产量减少;50 cm-20 cm宽窄行距配置对水稻形态发育和产量形成无明显影响,可提高插秧效率,改善田间环境。
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.
