摘要
在秦巴山区 ,随着海拔高度的升高 ,魔芋的出苗时间推迟。各品种出苗率的高低与种芋所带菌量有关。播种前进行种芋药剂消毒可明显提高出苗率。白魔芋抗病性强于花魔芋。花魔芋中 ,农林 2号抗病性相对较强。 8月中旬至下旬为病株率上升的最快时期。随着海拔升高 ,发病率有所下降。发病种类以白绢病为主。
The period of emergence of Amorphophallus was postponed with the ascendant of height above sea level in Qinba Mountain. The rate of emergence of Amorphophallus was associated with pathogenic bacteria. The rate of emergence was raised with disinfections of seed before the sowing. The disease resistance of Amorphophallus albus was better than Amorphophallus rivieri. In the Amorphophallus rivieri, the disease resistance of Nong-lin 2 was better than local ones. It was the fastest period that the rate of diseased was increased at the middle-late of August. The rate of disease was descended with the ascendant of height above sea level. The main disease was a Hypochnus centrifuge.
