高粱蚜是高粱的重要害虫,防治不及时可造成大量减产。每年如能提早、准确地发出预报可以提前为各级领导提供虫情,及时准备农药、械,适时开展防治。为加强高粱蚜综合治理,提高对高粱蚜发生程度预报的准确性,急需组建中期预报数学模型。为此,辽守省农科院植保所同辽宁省植保站、铁岭农科所、辽中县植保站等11个单位协作,从1984年7月开始利用微型机进行高梁蚜中期预报模型的研究.一、资料来源1984—1986年收集了开原、康平,铁岭、凌源、辽阳、朝阳、建昌、辽中、锦州、黑山等市县农科所(植保站)1970年次近1400组高梁蚜系统调查资料及有关气象数据。
Sorghum aphid is an important pest of sorghum, prevention and treatment can not result in large-scale production cuts. If we can make an early and accurate forecast every year, we can provide pests to leaders at all levels in advance and timely prepare pesticides and drugs so that prevention and control can be carried out timely. In order to strengthen the comprehensive management of sorghum aphids and improve the prediction of the degree of occurrence of sorghum aphid, the mathematic model of medium-term prediction is urgently needed. To this end, Liao Shou Provincial Academy of Agricultural Sciences plant protection with plant protection stations in Liaoning Province, Tieling Institute of Agriculture, Plant Protection Station in Liaocheng and other 11 units in collaboration with the beginning of July 1984 using the micro-machine aphid mid-term forecast model Source: 1984-1986 Nearly 1,400 groups of agricultural science institutes (plant protection stations) in cities and counties of Kaiyuan, Kangping, Tieling, Lingyuan, Liaoyang, Chaoyang, Jianchang, Liaozhong, Jinzhou and Heishan were collected from 1984 to 1986 Sorghum aphid systematic survey data and related meteorological data.
