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%.
