| 摘 要： | 以杂交早稻两优302为试验材料,研究了不同秧龄在移栽和抛栽方式下的生长特点、生育特性及产量表现.结果表明,移栽和抛栽表现趋势相同,适龄早栽具有早发和早熟优势,秧龄20 d时大田营养生长期延长3～10d,早熟2～6 d;秧龄与有效穗数、每穗总粒数和产量均呈极显著的负相关. |

| Abstract: | Using hybrid early rice Liangyou 302 as experiment material,the effects of seedling age on growth characteristics,breed features and yield performance of rice with transplanting and seedling throwing methods were studied.The results showed that there were the same performance tendencies in growth characteristics,breed features and yield performance between transplanting rice and seedling throwing rice.Early planting at suitable age had the advantages of premature and early maturity.The vegetative period of 20 days-seedlings prolonged 3~10 d and its mature period arrived 2~6 d ahead of time.There were very significant negative correlations between seedling age and effective panicles,total grain number and yield. |
| Keywords: | early rice seedling age cultivation methods yield yield component factors |
