香榧是我国特有的珍稀干果,是珍贵经济树种,古时称“三代果”。香榧生长缓慢,又被喻为“祖孙树”。但随着科技进步,运用科学的施肥方法、嫁接手段、先进的早产与矮化技术,现完全可以使香榧在第5～8年内开花结果,15年后开始盛产,若采用大砧木嫁接,第4年即可开花结果,第8年开始盛产。施用有机肥有利于提高香榧产量,提早结果,且能改善香榧的品质,提高香榧的营养与药用价值,是诸多技术中的关键措施。现将香榧的早产高产技术简介如下。 1.选择壮苗,科学种植应选强健有力、无病、根 Hong Kong is rare pecans unique to our country, is a precious economic tree species, ancient times, “three generations of fruit.” Xiang Hong slow growth, has been hailed as “grandchildren tree.” However, with scientific and technological progress, the use of scientific methods of fertilization, grafting methods, advanced premature birth and dwarfing technology, is now completely fragrant in the first 5 to 8 years flowering results, 15 years after the start of rich, if the use of large rootstock grafting, 4 years to bear fruit, the first eight years rich. The application of organic fertilizer is conducive to improving the yield of sweet potatoes, early results, and can improve the quality of sweet potatoes, improve the nutrition and medicinal value of sweet potatoes, is the key measure in many technologies. Xiang Hong now premature high-yielding technology is as follows. 1. Choose strong seedlings, scientific planting should be selected strong and powerful, disease-free, root
