摘要
为探讨不同栽培模式对大豆长动态及干物质积累分配的影响,以垦丰16为材料,在垄上三行窄沟密植栽培、垄三栽培和垄上单行栽培三种栽培模式下,测定株高、叶面积、光合势、干物质积累分配及产量。结果表明:株高、单株最大叶面积及光合势数值均以垄上三行窄沟密植栽培最高,其次是垄三栽培,垄上单行栽培株最低,在鼓粒期叶面积和光合势垄上三行窄沟密植栽培明显高于其它两个处理;处理间植株干物质积累差异主要出现在鼓粒期后,垄上三行窄沟密植栽培干物质阶段积累量和日积累量均高于垄三栽培和垄上单行栽培。垄上三行窄沟密植栽培产量最高达4052 kg.hm-2。
The effect of different cultivation patterns on growth tendency and dry matter accumulation and distribution of soybean were studied under the three cultivations of narrow trenches and compact planting of three lines on ridge（ NTCPTL）, integrated three technigue cultivation （ITTC）and single line on ridge （SLR）, with Kenfeng 16 as material. The plant height, leaf area, leaf area duration, dry matter accumulation and distribution and yield were investigated. The result showed that plant height,maximum leaf area per plant and leaf area duration were highest under the cultivation of NTCPTL,the second was ITrc and SLR was the last one. The leaf area and leaf area duration of NTCPTL were much higher than the other two treatments at podding. After podding, the differences of dry matter accumulation were obviously. The periodic accumulation and per day accumulation of dry matter under the cultivation of NTCPTL were higher than the other two cultivation patterns. The yeild of NTCPTL was the highest that came to 4052 kg·ha^-1.
