银杏的种子(白果)营养丰富,医食俱佳,是我国传统的重要出口物资;木质致密,不翘不裂,为建筑、工艺、家具之良材。近年来,山东省郯城县根据长期生产实践经验,营造了果材兼用型银杏园。现将有关技术介绍如下: 一、培育丰产树形 培育丰产的树形是获取银杏果材双丰收的一项重要技术措施。因为只有培育良好的树形,才能维持树体良好的从属关系和树势平衡,调整长树和结果的关系,进而达到壮树、高产和优质的目的。银杏干高对出材量、产果量有着重大影响。一般来说,矮干树早成冠、早结果、早丰产。但无良材可利用;而适宜的干高,既利于树冠
Ginkgo seeds (ginkgo) is rich in nutrition, health food and medicine are good, is an important traditional export materials; wood is dense, not Alice not cracking, for the construction, technology, furniture, good material. In recent years, Tancheng County, Shandong Province based on long-term production of practical experience and create a fruit and vegetable-based Ginkgo Park. Now introduce the technology as follows: First, cultivate high yield tree tree cultivate high yield tree is to obtain double harvest of ginkgo fruit an important technical measure. Only by cultivating a good tree shape can we maintain the good affiliation and tree balance of the tree body and adjust the relationship between the long tree and the result so as to achieve the goal of strong tree planting, high yield and high quality. Ginkgo stem high on the amount of wood, fruit yield has a significant impact. In general, early dry crown trees, early results, early bumper crop. But no good material available; and appropriate dry high, not only conducive to the crown
