改革开放以来,我省沿海各市、县大力发展龙眼生产。但由于良种嫁接苗供不应求和传统种植习惯的影响,种植了大量的实生苗。如莆田市新植龙眼10多万亩,实生苗约占3/4。龙眼实生苗品种混杂、劣种多,迟迟不能开花结果,或产量低,品质差。可是,目前龙眼嫁接存在一年中嫁接运期短、部位高、接头多、成本高、成活率低等问题,制约了嫁接换种的推广。1991年始,我们对龙眼实生树采用营养袋培育的良种嫁接苗(容器苗)进行低干嵌接试验,取得了理想效果。实践证明,采
Since the reform and opening up, our province coastal cities and counties to develop longan production. However, due to the shortage of seed grafting seedlings and the impact of traditional planting habits, planting a large number of seedlings. Such as Putian City, more than 10 million new plantation of longan, seedlings account for about 3/4. Longan seedling varieties mixed, inferior species, delayed flowering results, or low yield, poor quality. However, the current longan grafting there is a year of grafting run short, high parts, joints, high cost, low survival rate, restricting the promotion of grafting. From the beginning of 1991, we conducted a low-dry-fit test on the seedling grafted seedlings cultivated in the longan real tree with the nutrition bag and achieved the ideal result. Practice shows that mining
