Effects on Yield and Major Agronomic Traits Between Different Cultivation Patterns and Nitrogen Application Amounts for Variety Liangyou 616(Oryzae sativa L.)

摘要: 以两优616为材料, 采用两因素随机区组设计, 研究不同栽培方式与氮肥水平对两优616产量及主要农艺性状的影响。结果表明, 与常规栽培相比, 宽窄行错位栽培可提高齐穗期和成熟期的叶面积指数 (LAI) , 增加有效穗数和每穗总粒数, 提高产量水平。在供试氮肥水平条件下, 随施氮量的增加, 宽窄行栽培的产量水平也显著增加;但在常规栽培条件下, 过多施用氮肥, 则不利于产量水平的提高。Abstract: Two-factor randomized block design was applied to the effects on Yield and Major Agronomic Traits between Different Cultivation Patterns and Nitrogen Application Amounts for Variety Liangyou 616 (Oryzae sativa L.) .The results showed that the leaf area index (LAI) was increased in full-heading and maturing stages with the wide-narrow row alternation forms (T1) compared with the conventional planting (T2) , Further the effective panicles and grain number per panicle were not only increased, but also the level of yield was improved.The yield of wide-narrow row alternation form was also notably increased with nitrogen application rates improved under the condition of selected nitrogen.But too much nitrogen fertilizer application was not benefical for yield increased under the condition of the conventional planting.
