芒果是近年福建省大力发展的果树。针对我省芒果生产现状，笔者基于自身实践，参考当今芒果科技成果和生产经验，介绍芒果良种与高优栽培技术，供生产参考。

In our paper,pollution-free cultivation techniques of longan were studied by using related criteria and technical specifications for references.It also summarized the key technical points of pollution-free cultivation of longan including orchard construction,seedling planting,control of diseases and pests,harvesting treatment and orchard renewal.

Characteristics and cultivation technologies for four late-maturing longan cultivars in Fujian were introduced based on comprehensively analyzing the variety component in production and application in several longan-producing areas,and summarizing the years' observation and production practices.

The aims to investigate the influence of transplanting survival reason for longan trees,study and summarize technologies for increasing the survival rate of transplanting.Experimental observation of five batches transplanting of 195 longan trees from 2008 to 2012,which had more than 15 years.Analysis showed that the impact of longan trees transplanting survival was transplanting time,root protection,planting methods,conditions of plants and management,etc.Transplanting longan tree should choice reasonable methods of digging trees,the suitable season,implementation properly root management.Root cutting on transplanting longan tree in advance,digging tree in spring after root promoting,and transplanting survival rate can reach 95%.

引进泉薯830、福薯18、福薯7-6等三个叶菜用品种进行试种和品比分析。结果表明,泉薯830具有高产,泉薯18具有优质的突出优点,适合本地栽培;试验初步总结出叶菜用甘薯高产栽培技术要点。

早钟6号是我省经杂交选育而成的枇杷新品种;因其果大、质优、成熟期早,市场竞争优势突出,成为泉州近年广泛种植的果树良种.为探讨早钟6号枇杷的早产丰产栽培技术,笔者自1998年起在加锥农场开展相关试验,收到了一定的成效.该场枇杷植后2年平均树高1.5米、冠径1.7米,部分植株开始试产,株产2-3公斤;翌年又在扩大树冠的同时,多数植株投产结果,折合产量为每公顷1890公斤.现将其技术要点介绍如下:

琯溪蜜柚原产福建平和县琯溪河畔,自80年代后期,泉州地区的永春、洛江等地,相继进行引种、试种和小规模栽培,但终因普遍存在座果差、产量低、大小年结果严重等问题,而未能广泛推广.为此,1997年以来,我们在洛江区加锥农场对1995年种植的2.6hm2琯溪蜜柚山地果园开展相关技术试验,收到了增产增收成效.
