不同果树间作对花生生育动态及产量的影响

【目的】 研究花生在不同间作果树下的开花结实、生长规律及产量状况。【方法】 以花育25号、花育33号、山花7号、山花9号为参试材料,分析花生在枣树、巴旦木2种果树下的开花结实、干物质积累、产量性状等指标。【结果】 (1)不同果树间作下花生主要开花时间在第10~27 d,枣树间作较巴旦木间作花生总开花量多;(2)红枣间作下花生根、茎、叶干重积累更快,幼苗期2种间作果树下花生营养生长表现一致,随生育期的进展,营养体与生育体比值(V/R)发生变化,苗期最大后逐渐减小;(3)同一果树间作下,不同花生品种间的主茎高、侧枝长差异显著,花育22号、花育33号较山花7号、山花9号更强壮;(4)枣树间作下花生单株结果数、单株产量较巴旦木间作高。【结论】 红枣适宜间作品种为花育22号,巴旦木适宜间作品种为花育22号、花育33号,红枣更适宜与花生间作。

Effects of Different Fruit Tree Intercropping on Growth Dynamics and Yield of Peanut

【Objective】 To explore the flowering and fruiting, growth and yield of peanut under different intercropping fruit trees.【Method】 Using Huayu 25, Huayu 33, Shanhua7 and Shanhua 9 as test materials, the indicators of peanut flowering and fruiting, dry matter accumulation, and yield characteristics under two fruit trees of jujube and badam were analyzed.【Result】 (1) The main flowering time of peanut under intercropping of different fruit trees was from 10 to 27 days. The total amount of peanut flowering was higher in jujube intercropping than in Badam intercropping.(2) Under the intercropping of jujube, the dry weight accumulation of peanut roots, stems and leaves is vegetative growth performance of peanut under the two intercropping fruit trees at the seedling stage was consistent. the growth period , the ratio of vegetative body to fertility (V/R) and gradually after the maximum seedling stage. (3)Under the same fruit tree intercropping, the main stem height and side branch lengths of different peanut varieties were significantly different. Huayu 22 and Huayu 33 were stronger than Shanhua 7 and Shanhua 9.(4) Fruit number per plant and yield per plant in jujube tree intercropping were higher than those in Badam intercropping.【Conclusion】 The suitable of jujube works Huayu No. 22, and the suitable varieties of Badam are Huayu 22 and Huayu No. 33. Red dates are more suitable for intercropping with peanuts.
