为切实搞好棉花检疫性病害的综合防治,确保棉花稳产高产,现就如何因地制宜应用棉花抗病品种问题,谈一些看法。 (一)棉花枯萎病在我县已有较长历史。从1964年最初发现一块1.5亩病田,到1978年已扩展到1826亩。最近三年病害蔓延速度更是惊人。到1981年己扩展到16363亩,占全县棉田总面积的7.1%,涉及644个生产队,占全县生产队总数的18%。主要病因可归纳为:1.种子基地的种子带菌传播。2.部份社员长期用有病花壳花屑喂养牲畜和填放棚舍,因肥料带菌传播。3.在推广棉花营养钵育苗移栽和利用棉田育油菜秧过程中,部分社队缺乏病因档案,用病因做苗床,更扩大了传播范围。
In order to effectively do a comprehensive inspection and quarantine of cotton disease prevention and control to ensure stable and high yield cotton, cotton is now on how to apply the disease-resistant varieties, talk about some ideas. (A) Fusarium Wilt has a long history in our county. From the first discovery in 1964 a piece of 1.5 acres of disease fields, 1978 has been extended to 1826 acres. The spread of disease in the recent three years is even more alarming. By 1981 it had expanded to 16363 mu, accounting for 7.1% of the total area of the county’s cotton field, involving 644 production teams, accounting for 18% of the county’s total production team. The main causes can be summarized as follows: 1. The seeds of seed-based transmission of bacteria. 2. Some members have long used sick flowers and shelled flowers to feed livestock and fill the sheds, because of the spread of fertilizers. 3. In the promotion of cotton seedling nutrition training bowl transplanting and utilization of cotton seedling oiling process, some of the community team lack of cause files, with the cause of the seedbed, but also expanded the scope of dissemination.
