| 摘要: |
| 该研究用双因素裂区设计,在四种栽培模式和两种类型复合肥条件下,分析了玉米杂交种隆平206的农艺性状及干物质积累的影响。隆平206的株高、生长率均在等行距和宽窄行间差异不显著,但与等行距一穴两株间差异显著; 穗位高在等行距和宽窄行[(70+50)cm]间差异不显著,但与宽窄行[(90+30)cm]和等行距一穴两株间差异显著; 茎粗在各处理间差异不显著,栽培模式对隆平206穗位上第1叶和穗下第1叶的叶夹角影响显著,对穗上第1叶的叶向值影响显著,对穗下第1叶的叶向值影响不显著,对不同时期穗位节和穗位上节的茎杆强度影响差异显著,对不同时期干物质积累影响差异显著。隆平206在宽窄行[(90+30)cm],地富原玉米专用复合肥时,隆平206农艺性状各指标达最佳状态,栽培模式对隆平206不同时期干物质积累影响差异显著,在拔节期、大喇叭口期、开花期、乳熟期、成熟期,隆平206在栽培模式宽窄行(70+50)cm时干物质积累量均最大。该研究结果为玉米杂交种隆平206的栽培管理和施肥提供了依据。 |

| Abstract: |
| We studied the effects of four cultivation patterns and two compound fertilizer types on the root morphology index at seedling stage, the volume and the dry weight of root at elongation stage, the physiological property of root, leaf and stem, the agronomic traits and dry matter accumulation, grain filling and N, P and K accumulation, photosynthetic characteristics and yield components. This experiment was done at the science and technology garden in Anhui Science and Technology University and designed by two-factor split block design. The main plot was row-spacing allocation and double plants a hole. The four seeding styles were equal row spacing(A1, 60 cm), equal row spacing and double plants a hole(A2, 60 cm), wide and narrow row spacing(A3, 70 cm+50 cm), wide and narrow row spacing(A4, 90 cm+30 cm), respectively. The vice plot was base fertilizer type and used Stanley compound fertilizer and Difuyuan special compound fertilizer for corn. The experiment had eight treatment groups and four repetitions for each group. The seeding density was 67 500 cobs·hm-1, the width of each plot was 3 m, and the length was 6.67 m. The underground fertilization amount was 750 kg·hm-1. The plant height and growth rate of Longping 206 had not significant difference between equal row spacing and wide and narrow row spacing, but had significant difference during the pattern of equal row spacing with double plants a hole. The ear height had not significant difference between A1 and A3, while had significant difference between A4 and A2. The stem diameter had not significant difference between each treatment. The effects of cultivation patterns on the angle between first leaf of above ear and first leaf of under ear had significant difference, and on the first leaf orientation value of above ear also had significant difference, but on the first leaf orientation value of under ear had not significant difference. The effects of cultivation patterns on the stem intensity of ear knob and upper ear knob and on the dry matter accumulation at different stages had significant difference. Longping 206 in wide narrow row spacing(90+30)cm, Difuyuan special compound fertilizer, the indexes of agronomic characters of long reached the best state, the effects of cultivation pattern of dry matter accumulation of significant difference of Longping 206 on different periods, at jointing stage, booting, flowering stage, milk stage and mature period, the amount of dry matter accumulation of Longping 206 were the biggest in cultivation mode row(70+50)cm. It illustrated that different cultivation patterns and compound fertilizer types made important effects on the growth of Longping 206 and provided some information for cultivation management and fertilization of Longping 206. |
