摘要
【目的】明确不同间作模式对新疆花生生长发育和产量的影响。【方法】设置两种间作模式:花生||棉花与花生||打瓜,分别从农艺性状、根系特征、产量和种间竞争力进行分析其对花生的影响。【结果】生长前期,花生||打瓜下花生株高增长率高于花生||棉花。花生||棉花的花生叶片叶绿素含量高于花生||打瓜。与单作花生相比,花生||打瓜中花生减产16.50%,打瓜增产22.34%;花生||棉花中花生减产36.10%,棉花增产7.71%。两种模式土地当量比值均大于1,种间竞争力均大于0。【结论】花生||打瓜有利于前期花生的株高增长;花生||棉花在提高花生叶绿素含量上具有明显优势;花生为劣势作物,间作可提高棉花和打瓜的产量,两种间作模式均能提高土地当量率,提高农田的可持续性。
[Objective]To clarify the effects of different intercropping patterns on the growth,development and yield of peanut in Xinjiang.[Methods]Two intercropping modes were set up:peanut intercropping cotton and peanut intercropping melon,and the effects of agronomic traits,root characteristics,yield and interspecific competitiveness on peanut were analyzed.[Results]In the early growth stage,the growth rate of peanut plant height in peanut intercropping melon was higher than peanut intercropping cotton.The chlorophyll content of peanut leaves in peanut intercropping cotton was higher than in peanut intercropping melon.Compared with monoculture peanut,in peanut intercropping melon,the yield of peanut was reduced by 16.50%,and the yield of melon was increased by 22.34%;in peanut intercropping cotton,the yield of peanut decreased by 36.10%,and the yield of cotton increased by 7.71%.The land equivalent ratio of the two models was greater than 1,and the interspecific competitiveness was greater than 0.[Conclusion]Peanut intercropping melon is conducive to the plant height growth of peanut in the early stage.Peanut intercropping cotton had obvious advantages in increasing the chlorophyll content of peanut.Peanut is a disadvantaged crop,and intercropping can increase the yield of cotton and melon,and both intercropping modes can increase the land equivalent rate and improve the sustainability of farmland.
