1984～1986年我们对本市主要芦笋产区进行了调查,一般发病率为30～60％,严重田块高达100％,损失60％以上,常因此毁种绝产。此病的严重发生,不但影响芦笋的丰产稳产,而且种植面积逐年减少,致使工厂加工量不足,影响出口创汇。由此可见,要提高单位面积产量,病害是迫切需要解决的重大课题。为此,我们于1984年正式设题对芦笋病害和以栽培技术为基础的综合防治措施进行了研究。经三年研究,发现茎枯病是本市芦笋上的主要病害。现将研究结果初报如下:
From 1984 to 1986, we surveyed the main producing areas of asparagus in our city. The average incidence is 30-60%. The serious plots are as high as 100% and the losses are over 60%. The serious occurrence of this disease not only affects the high and stable yield of asparagus, but also reduces the planting area year by year, resulting in insufficient processing capacity of the factory and affecting export foreign exchange earnings. Thus it can be seen that disease is an important issue urgently needed to be solved in order to increase yield per unit area. To this end, we conducted a formal study in 1984 on asparagus disease and cultivation techniques based on a comprehensive prevention and control measures were studied. After three years of research, it was found that the stem blight was the main disease on the city asparagus. The results of the first report is as follows:
