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%。
Taking walnut cultivars “Hongling” of Xi’an city as test materials, different methods of pruning, fertilizing methods, intercropping modes and lamp insecticide were used to study the effects of fine cultivation techniques of young seedlings of walnut Tree Growth, Early Yield, Insecticidal Effects and Soil Nutrients. The results showed that the combination of winter and summer shear increased the tree growth by 35% compared with that by simple winter shears, while the intercropped soybean increased the crown growth by 87%, the insecticidal effect by strong electric field solar insect light was 80.6% Combined application of excrement and walnut fertilizer can make soil organic matter, alkaline hydrolysis nitrogen, organic phosphorus, available potassium and many trace elements are greatly improved. Fine management of 4-year-old walnut tree compared with the extensive management, fine management can increase the crown 6%, increase production 92%.
