种植密度对夏直播棉花生长及产量的影响
|
摘要
在一次性见花施肥、固定氮磷钾施肥比例条件下,研究了5个种植密度对夏(麦/油后)直播棉花(Gossypium spp)主要农艺性状、结铃和产量的影响。结果表明,夏直播棉花在种植密度6.75万～7.50万株/hm~2时,对单株成铃数、铃重等产量相关性状有明显影响,烂铃数量随着种植密度的增加而呈增加趋势。因此,该种植密度可作为夏直播棉花高产栽培的参考密度。
The effects of five planting densities on main agronomic characters, boll setting and yield of direct-seeded cotton(Gossypium spp) in summer were studied under the condition of one-time flowering fertilization and fixed N, P and K fertilization ratio. The results showed that the boll number and boll weight of direct seeding cotton in summer had obvious effects on yield-related traits when planting density was 67 500～75 000 plants/hm~2, and the number of rotten bolls would increase with the increase of planting density. Therefore, the planting density could be used as a reference density for high-yield cultivation of direct seeding cotton in summer.
