育苗移栽是棉花高产稳产的栽培技术措施之一。在育苗中,加强苗期管理,防治病害是确保冷床育苗“早、全、齐、壮”的重要环节。为了摸清我省主要产棉县苗床病害种类及为害情况,总结苗床病害经验,于1981年4月下旬,我们先后对大荔、渭南、华县、临潼、武功、乾县、三原、泾阳等8县16个公社,19个生产大队的2,424个苗床发病情况进行了调查,现将结果报道如下。一、病害种类及分布叶病主要是黑斑病、茎枯病,其次是红腐病及零星的角斑病;根病主要是立枯病、炭疽病,红腐病的发病程度因地而异,以泾阳县云阳公社最重。在华县调查,苗床内有苗期枯萎病。
Seedling transplanting is one of the cultivation techniques for high and stable cotton production. In nursery, strengthen seedling management, disease prevention is to ensure that cold bed nursery “early, all, Qi, Zhuang,” an important part. In order to find out the main cotton seedbed disease types and damage situation in our province, summed up the experience of seedbed disease, in late April 1981, we successively carried out the investigation on Dali, Weinan, Huaxian, Lintong, Wugong, Qianxian, Mianyang, Jingyang and so on The incidence of 2,424 seedbed diseases in 16 communes and 19 production brigades in 8 counties was investigated. The results are reported below. First, the type and distribution of disease leaf disease is mainly black spot, stem blight, followed by red rot and sporadic angular leaf spot; root blight is mainly blight, anthracnose, red rot due to ground disease and Different to Jingyang County, Yunyang commune heaviest. Investigation in Huaxian, there seedling blight within the seedbed.
