摘要
针对造成成龄枣树低产的原因,提供了沙土类型区枣树低产林改造的关键性技术:科学调控水肥、增加树体营养;对衰老树刺激多年生隐芽萌发新生枣头,培养青壮年结果母枝(3～7a生枣股),增加结果能力;通过人工修剪措施或化学调控技术对花果进行量化管理,提高单产和果实品质;可持续综合控制病虫危害;对新技术进行组装配套,提供标准化技术操作规程。
The key techniques for improving of low-yield jujube trees in sandy soil regions are put forward in this paper, according to the low-yield reasons of adult jujube trees. These techniques are as follows: improving tree nutrition condition by scientifically controlling water and fertilization;starting the germination of crypto-buds on elder trees to form new crowns and cultivating young fruiting branches in order to improve fruiting ability; scientifically controlling the amounts of flowers and fruits to get high yeild and quality; sustainably controlling of diseases and inseet pests and,applying new techniques and providing standard operating instructions.
