聚合草矮缩病是一种由类菌原体(MLO)侵染所致病害。该病扩展蔓延迅速,抑制生长,严重影响聚合草的生产。用抗菌素处理是鉴别植物类菌原体病害的一种简便方法,也是一种有效的防治措施。为查明不同抗菌素、不同浓度、不同处理时间、不同使用方法对病株的作用,寻求经济可行的防治方法,1982—1985年相继进行了室内盆栽和田间小区防治试验。盆栽试验表明用50ppm的四环素浸根24小时防效最佳,田间试验证实,根侧穴施四环素工业废渣作基肥,地上部生长期喷施50ppm工业四环素5次,平均增产23％,产值净增收17％。
Aggregate grass dwarf is a disease caused by the infection of the mycoplasma (MLO). The expansion of the disease spread rapidly, inhibit growth, seriously affecting the production of polymerized grass. Antimicrobial treatment is an easy way to identify phytoplasma diseases and is also an effective control measure. In order to find out the effect of different antibiotics, different concentration, different treatment time and different using methods on diseased plants and to seek economical and feasible methods of prevention and cure, the indoor potted plants and field plots were controlled in 1982-1985. Pot experiments showed that 50ppm of tetracycline rooted for 24 hours, the best control effect of field experiments confirmed tetracycline industrial residue as a base fertilizer, the shoot growth stage spraying 50ppm industrial tetracycline 5 times, an average increase of 23%, net output value 17%.
