| 摘 要： | 选择我省不同气候、生态条件和地力水平的陵县和菏泽市研究济南 17号小麦播种期和基本苗与产量的关系。结果表明 :不同的播种期和基本苗通过对群体发育的调控 ,从而对群体LAI、单位面积穗数、每穗粒数和产量产生显著的影响 ;但播期和基本苗对济南 17号千粒重的影响不大 ,不同地域、不同地力和气候因素对千粒重的影响似乎更大些。研究还表明济南 17号小麦具有突出的耐大群体的特点 ,但不适宜晚播。对两试点产量水平分析表明 ,济南 17号适宜在高肥地力条件下种植。 |

Effect of Population regulation on grain yield and agronomic characters in high quality bread wheat variety Jinan 17 |
|
| Abstract: | The experiment concerned with the relationship between sowing date, seed rate and grain yield was conducted at two different ecological locations in Shandong Province by using high quality bread wheat variety Jinan 17 as an observation material Results showed that plant population were regulated by both sowing date and seed rate Leaf area index (LAI), head number per hectare, grain number per spike and grain yield were all affected significantly by plant population regulation 1000-grain weight was not significantly affected by sowing date and seed rate, but varied greatly with different ecologic, climatic conditions and soil fertility Jinan 17 could get high yield at high seed rate with the initial plant density up to 300×10 4 plants per hectare, but it wasn't suited for late sowing As a result, Jinan 17 is a variety suited to plant in high soil fertility with good irrigation conditions |
| Keywords: | High quality wheat variety sowing date seed rate grain yield |
