研究了彩色马蹄莲细菌性软腐病菌落的生长与温度的关系 ;不同种球规格及GA3处理对彩色马蹄莲花期、产花量和质量的影响。结果表明 ,2 7℃以上高温会明显加重细菌性软腐病的发生 ;大规格种球的始花期早于中、小规格种球 ,产量和质量也均高于中、小规格种球 ;GA3处理能有效提高产量
The relationship between the temperature and the growth of colony of bacterial soft rot of colored calla lily was studied. The effects of different bulbs and GA3 treatments on the flowering stage, yield and quality of calla lily were studied. The results showed that the incidence of bacterial soft rot disease was significantly increased when the temperature was above 27 ℃. The flowering period of large-sized bulbs was earlier than that of medium-sized and small-sized bulbs, and the yield and quality were also higher than those of medium and small bulbs. GA3 Processing can effectively improve the yield
