- 摘要:
- 以西安市核桃主栽品种“香玲”为试材，采用不同的修剪方法、施肥方式、间作模式、灯具杀虫等管理方法，研究了良种早实核桃幼树精细栽培技术对核桃幼树生长、早期产量、杀虫效果和土壤养分的影响。结果表明：冬、夏剪相结合比单纯冬剪可提高树体生长量35%，间作黄豆比不间作可提高冠幅生长量87%，强电场式太阳能杀虫灯杀虫效果80.6%，牛粪与核桃专用肥复合施用可使土壤有机质、碱解氮、有机磷、速效钾及多种微量元素均有较大提高。对4年生核桃树精细管理与粗放管理相比，精细管理可增大冠幅6%，提高产量92%。
- Abstract:
- Using the major walnut variety ‘Xiangling’ in Xi’an as experimental material，the effect of the precise cultivation and management technologies of improved early-fruiting variety of young walnut trees on the sapling growth，early yield，insecticidal property and soil nutrients were investigated by the means of pruning method，fertilization pattern，interplanting mode and insecticidal lamps.The results showed that the combination of winter and summer pruning made the growth of tree rise up 35% than the single summer pruning.Soybean intercropping improved the crown growth by 87% than non-intercropping.The insecticidal effect of strong electric field solar insecticide lamp was 80.6%.The soil organic matter，alkali solution nitrogen，organic phosphorus，available potassium and various trace elements were increased by applying cow dung and walnut specialty fertilizer.Compared with the extensive management，the precise management of walnut trees for 4 years old could enlarge the crown by 6% and raise the production by 92%.
