风沙易旱地区不同种植模式对花生生理性状及产量的影响

Effects of different planting patterns on physiological traits and yield of peanut in sand drought-prone areas

以花生品种阜花17号为材料,在风沙易旱地区采取4种花生种植模式进行对比试验,研究不同种植模式对花生LAI、干物质、叶绿素、产量及农艺性状的影响.结果表明:大垄双行覆膜种植模式的LIA、叶绿素含量、干物质积累等生理性状表现相对较好,能显著提高花生产量,其次是垄上双行单粒交错裸地种植模式.坐畦双行覆膜种植与垄上双行单粒交错裸地种植模式较适宜风沙易旱地区.

Peanut variety Fuhua 17 as material,four peanut cropping patterns were set in the sandy semi-drought area,the effects of different planting patterns on LAI,dry matter,chlorophyll,yield and agronomic traits of peanut were studied.The results showed that physiological traits of LIA,chlorophyll content,dry matter accumulation on double furrow planting pattern of film was relatively good,could significantly improve peanut production.Second was the mode of double ridge line by single grain staggered planting on the bare ground.So,the modes of double furrow planting pattern of film and double ridge line by single grain staggered planting on the bare ground are more appropriate cropping patterns in the region.
