食芽象甲是我国北方枣林重要害虫。在研究了食芽象甲的生物学特性和为害嫩芽的特点的基础上,于1991~1993年在永和县枣区采用化学药剂防治和人工震落收集虫体的综合措施,有效地控制虫害,促进了枣树生长和结果。与对照区相比,防治区的虫口减退率达90.8%~96.3%;枣树正常发芽率提高93.0%;生长前期枣吊数增加16.6%~28.2%,枣吊长度平均增加34.3%~44.1%,前期座果率提高99.0%;采收期枣吊数增加18%~25%,枣吊长度增加7.7%,挂果数提高74.6%~85.2%,仅产量一项比对照区增加3~4倍,且枣果个大,质优。重要的是,树体发芽早,生长期长,光合作用面积大,有机物积累丰富,为连续优质丰产奠定了基础。
Meal bud as a major northern China jujube pests. Based on the study of the biological characteristics and the characteristics of the damaged shoots, the comprehensive measures of chemical agent control and artificial ground-shaking collection of parasites in the date region of Yonghe County from 1991 to 1993 were carried out to effectively control pests , Promote jujube growth and results. Compared with the control area, the reduction rate of the population in the control area was 90.8% ~ 96.3%. The normal germination rate of jujube increased by 93.0%. The number of jujube increased 16.6% ~ 28.2% and the length of jujube increased by 34.3% ~ 44.1% , The early stage of fruit rate increased 99.0%; harvest jujube hanging number increased 18% to 25%, jujube hanging length increased 7.7%, the number of fruiting increased 74.6% to 85.2%, only a yield increase of 3 to 4 times the control area , And jujube a large, high quality. Importantly, the early germination of trees, long growing season, photosynthetic area, organic accumulation, laid the foundation for continuous high-yield.
