马占相思苗期病害主要有茎腐病 (FusariumoxysporumSchiechtandRhizoctoniasolaniKuhn)、炭疽病(ColletorichumgloeosperioidesandC truncatum )和白粉病 (Oidiumsp ) 3种。它们主要危害 1生年以内苗木 ,在苗木生长期均可发病。前两者对扦插苗危害较大 ,是致死原因 ,可采取综合防治措施对其进行防治 ;后者对 2年生以内实生苗和扦插苗均有危害 ,且普遍而严重 ,但一般不造成苗木死亡。白粉病是以病原为主导的病害 ,防治上以控制病原菌为主。苗期害虫主要有蟋蟀和白蚁 ,它们主要取食嫩梢 ,咬断苗木茎基及根系 ,造成新造林地缺苗 ,防治上以诱杀兼捕杀为主
Acacia seedlings diseases mainly stem rot (FusariumoxysporumSchiechtandRhizoctoniasolaniKuhn), anthracnose (ColletorichumgloeosperioidesandC truncatum) and powdery mildew (Oidiumsp) 3 kinds. They mainly endanger the seedlings within one year of birth, the disease can be in the seedling growth stage. The former two are more harmful to cutting seedlings, which is the cause of death and can be controlled by comprehensive prevention and treatment measures. The latter is harmful to both seedlings and cutting seedlings within 2 years of age, and is generally serious, but generally does not cause the death of seedlings . Powdery mildew is the pathogen-dominated disease, prevention and control mainly to control pathogens. Seedling pests mainly crickets and termites, they are mainly feeding young shoots, bite off the stems and roots of seedlings, resulting in the new afforestation of the lack of seedlings, the control of trapping and killing mainly
