- 摘要:
- 本研究以垦农23 为试验材料,探讨养分调控与栽培模式对大豆干物质积累及产量的影响。采用二因素裂区试验设计,主区为养分调控处理,设置优化施肥( D) 和对照施肥( N) 2 个水平; 副区为栽培模式处理,在130 cm 的大垄上分别设置垄上4 行、垄上5 行和垄上6 行3 种模式。结果表明: 大豆生育期内叶面积指数和干物质积累过程均呈单峰曲线,其峰值出现在结荚期至鼓粒盛期之间。鼓粒期干物质积累与产量呈极显著正相关。优化施肥( D) 处理通过提高叶面积指数和干物质积累量,在不同栽培模式下的产量均高于对照施肥( N) 处理,其中D-4 比N-4 提高4. 3%,D-5比N-5 提高17. 1%,D-6 比N-6 提高29. 5%。本试验条件下,优化施肥技术与130 cm 垄上6 行栽培模式,在34 万株·hm - 2的种植密度下是当地大豆高产优质合理种植模式。
- Abstract:
- In order to study the effects of cultivation patterns and nutrient regulation on dry matter accumulation and yield ofsoybean,the plot experiment was conducted with Kennong 23. The optimized fertilization( D) and compared fertilization( control,N) were the main plots,while cultivation patterns treatments,4,5 lines and 6 lines on the ridge of 130 cm in width,were the secondary plots. The results showed that dry matter accumulation of the whole plant followed a single peak curve andthe peak appeared from pod stage to seed filling stage. Seed yield was positively correlated with the dry matter accumulation inthe seed filling stage. The treatment with optimized fertilization( D) had higher leaf area index and dry matter accumulationthan control. Compared with the control( N) ,the yield of D-4 increased by 4. 3%,D-5 increased by 17. 1% and D-6 increasedby 29. 5%. The treatment with the density of 340 000 plants·ha - 1 combined with optimized fertilization and 6 lines onthe 130 cm ridge was the most reasonable planting pattern for high yield and good quality for local soybean production.
