要搞好枣树虫害的防治,首先要掌握虫情及其发生发展趋势,作到心中有数,才能准确、及时、有效地消灭虫害。欲想达到这一目的,就必须掌握害虫的一般规律、特殊规律及其与气候、环境条件的关系,加以分析,正确判断害虫未来的发生发展趋势,预先测出并及时报出防治的有利时机,使有关部门和枣区群众,作好充分准备,及时采取经济、有效的防治措施,以达到控制虫害,确保红枣优质高产的目的。虫害的预测预报方法,按测报时间可分为长期测报和短期测报,按病虫发生、为害和分布可分为发生期测报、发生量测报和扩散动向测报。目前,在枣树虫害方面,由于科技水平的局限性,只能进行短期的发生期和发生量的测报。现将具体方法简介如下。
To do a good job in the prevention and treatment of jujube pests, we must first grasp the development of insect pests and trends, be aware of, in order to accurately, timely and effective elimination of pests. In order to achieve this goal, we must grasp the general rules and special laws of pests and their relations with climatic and environmental conditions, analyze them and correctly judge the occurrence and development trend of pests in the future, pre-measure and timely report favorable opportunities for prevention and treatment So that the relevant departments and the people in the Zaoqu area are fully prepared to take timely and effective economic and effective prevention and control measures so as to achieve pest control and ensure high-quality and high-yield dates. Pest prediction and forecasting methods can be divided into long-term measurement and short-term measurement according to the measurement time. According to the occurrence of pests and diseases, the damage and distribution can be divided into the measurement of occurrence, the measurement of occurrence and the trend of spread. At present, jujube tree pests, due to the limitations of science and technology, can only be short-term occurrence and occurrence of the measured. The specific method is as follows.
