摘要
山地苹果是榆林地区农民经济收入的主要来源,对农民的增产增收具有极其重要的作用。水肥一体化又称施肥灌溉或肥水灌溉技术,这种技术可根据果树的需水需肥特点,在压力作用下将肥料溶液注入灌溉输水管道,使肥料和水分准确均匀地滴入果树根区,适时、适量地供给果树,实现了水肥同步管理和高效利用的一种节水灌溉施肥技术,该技术的节水、节肥、省工效果非常明显。本文分析了榆林山地苹果水肥一体化的时间、物候期、农事要点及操作要求,并按照时间顺序,根据果树的不同物候期制定了不同的农事操作技术要求,旨在为果树的栽培管理提供参考依据。
Mountain apple is the main source of farmers’economic income in Yulin area,and it plays an extremely important role in increasing farmers’production and income.Water and fertilizer integration is also known as fertilization irrigation or fertilizer irrigation technology.This technology can inject fertilizer solution into irrigation water pipeline under pressure according to the characteristics of water and fertilizer demand of fruit trees,so that fertilizer and water can be dripped into root zone of fruit trees accurately and evenly,and the fruit trees can be supplied timely and appropriately,thus realizing synchronous management and efficient utilization of water and fertilizer.A water-saving irrigation and fertilization technology,the technology of water-saving,fertilizer saving,labor saving effect is very obvious.In this paper,the time,phenology,agronomic key points and operation requirements of apple water and fertilizer integration in Yulin mountainous area were analyzed,and different agronomic operation technical requirements were formulated according to different phenological stages of fruit trees in order to provide reference for the cultivation and management of fruit trees.
