| 摘 要： | 为探讨蒜茬花生高产栽培种植模式,2014—2015年在聊城农科院科技示范园对其田间配置方式及种植密度进行试验研究。试验采用裂区试验设计,田间配置方式(垄上小行距)为主处理,设A1(25 cm)、A2(35 cm)、A3(45 cm);密度为副处理,设单粒精播B1(18万株/hm~2)、B2(21万株/hm~2)、B3(24万株/hm~2)、B4(27万株/hm~2)、双粒穴播B5(13.5万株/hm~2)5个密度水平,研究田间配置方式和种植密度对花生生育性状、产量性状、干物质积累及田间群体透光率的影响。研究结果表明,主处理垄上小行距A1(25 cm)、A2(35 cm)对花生群体透光率、单株结果数、饱果数和荚果干重的有利影响显著高于A3(45 cm),其他性状主处理间差异不大;密度对群体透光率、植株干重、产量性状影响较大,结果显示花生饱果期副处理B2(21万株/hm~2)、B3(24万株/hm~2)、B5(13.5万株/hm~2)群体透光率较低,即群体光截获率较高,更有利于光能利用率的提高。产量结果以A1B3最高,与A1B2、A2B2、A2B3处理产量差异不显著,与其余主副处理协作均差异显著。

Study on Different Field Collocation Patterns and Densities of Peanut After Garlic Harvest |
| |
| Abstract: | To achieve high yield cultivation techniques of peanut after garlic harvest, a field experiment on field collocation pattern and density was conducted in Liaocheng Academy of Agricultural Sciences from 2014 to 2015. The split plot design was employed with main plot of field collocation patterns, sub-plot of density. Three field collocation patterns (25, 35, 45 cm) and five densities (single-seed sowing 18×104, 21×104, 24×104, 27×104 plants/hm2 and double-seed sowing 13.5×104 plants/hm2) were set. Effect of field collocation pattern and density on peanut growing characters, yield characters, dry matter accumulation and field transmittance was analyzed. The results showed that the beneficial effect of field collocation patterns A1(25 cm) and A2(35 cm) on field transmittance, pod number per plant, full pod number and pod dry weight was significantly superior to those of A3(45 cm); density had a significant impact on field transmittance, plant dry weight and yield characters. During pod filling stage of peanut, field transmittance of B2(21 × 104 plants/hm2), B3(24 × 104 plants/hm2), B5(13.5×104 plants/hm2) was low, it was conducive to increasing light utility efficiency. A1B3had the highest yield, which had no significant difference with A1B2, A2B2 and A2B3, but significant difference with other treatments. |
