| Abstract: | Experiments dealt with the effects of base manure amount, sowing time and density in autumn Chinese cabbage field on the occurrence of downy mildew Peronospora parasitica (Pec) Fr. , black rot Xanthomonas campestris (Pammel)Dowson and soft rot Erwinia caro-tovora (Jones) Holl diseases were carried out by adopting the orthogonal rotation combined design. The order of importance of these three factors for eace diseases was determined. and the corresponding regression equations were developed. A series of perliminary numerical bases in optimized management of these significant practices for disease control and high yield targets of cabbage production were derived. |
