有机荔枝园不使用化学农药，蜘蛛种类多，个体数也较多。

The richness and number of Salticidae individuals in the abandoned litchi orchard also increased .

2类果园卷叶蛾类群落的多样性相比，荔枝园要高于龙眼园。

The diversity index of community in litchi orchard was higher than that in longan orchard .

深圳市荔枝园昆虫群落共包括18个目（昆虫纲16个目和蛛形纲2个目），共369种。

The results indicate : The insect community in Shenzhen city includes 18 orders ( insecta : 16 orders , spider : 2 orders ) and 369 species .

在化学防治荔枝园中只采集到荔蝽卵平腹小蜂，而其寄生率也仅达到0.2%-2.8%。

Papillosa oviposition . Only A. japonicus was collected in the chemical controlled litchi orchard and the percentage of eggs parasitized by this wasp was only 0.2 % - 2.8 % .

其中，有15种分布于荔枝园，32种分布于芒果园，2种分布于龙眼园，1种分布于番石榴上。

Among them , there were 15 species distributed in litchi orchard , 32 species , in mango orchard , 2 species , in longan orchard and one species in guava orchard .

明确了目前广西部分龙眼荔枝园中的卷叶蛾类有20种，其中9种过去尚未见报道。

There were 20 species leaf rollers in parts of longan orchard and litchi orchard in Guangxi and 9 species of them were not reported as a pest on longan and litchi in the past time .

过量使用化学农药造成了荔枝园生态系统的破坏、害虫抗药性增强及再猖獗、果实品质下降及环境污染等一系列严重问题。

Owing to excessive pesticide used , a series of serious problems are produced , for example , the destructive of the ecosystem in the litchi-orchard , the pest anti-chemical and re-rampancy , the decreasing of the fruit quality and the environment pollution , etc .

受施肥投入影响，N、P、K养分在柑桔、荔枝和龙眼园上有增加的趋势，而芒果园在全N、速效P、速效K方面则有较大的下降。

As a result of increased fertilizer application , soil N , P and K showed an increasing trend in the Orange , Litchi and Longan orchards , But total N , readily available P and readily available K in the Mango orchard dropped significantly .
