根据我国季风气候的特点:年际间变异性大;可以导致棉田生态系失去平衡,造成棉花害虫暴发成灾;农村种植结构不合理,变化频繁;管理水平低,植保服务体系适应不了农村经济体制的改革;以及有些害虫管理的关键技术还有待进一步研究解决等情况,预计未来3—5年是我国主要棉花害虫发生严重的时期。到了5—10年以后,有关棉花的经济政策、优质商品棉生产基地及与之相适应的区域性病虫测报站和植保服务体系的建设都合理了;专业测报站内建立起多种病虫害的分区预报模型和决策模型,并可以利用自动化的手段,随时把病虫
According to the characteristics of the monsoon climate in our country, the variability in the interannual period can lead to the imbalance of the cotton ecosystem and cause the outbreak of cotton pests. The planting structure in rural areas is irrational and changes frequently. The management level is low and the plant protection service system can not adapt to the rural economic system The key technologies of some pest management have yet to be further studied and solved. It is estimated that the next 3-5 years will be a serious period for major cotton pests in our country. By 5-10 years, the economic policies concerning cotton, the production base of high-quality commodity cotton and the construction of the regional pest forecasting stations and plant protection service systems that are appropriate to them all are reasonable; the division of various pests and diseases Forecast models and decision models, and can use automated means to put pests and diseases at any time
