摘要
裸露矮化线虫(TylenchvrhynchusnudusAllen1955)是华南农业大学试验农场甘蔗上的主要病原线虫,此线虫外寄生于甘蔗根的表皮细胞和根毛上,引起报数量减少和坏死,严重时腐烂;地上部矮化。盆栽接种试验表明,此线虫引起甘蔗产量降低5.26~14.74%。田间小区药剂防治试验表明,亩施克线丹2、3和4kg或呋喃丹4kg,增产百分率分别为20.68%、38.72%、23.17%和14.15%。
Tylenchorhynchus found to be the main pethogenic nematodes in the sugnrcane ficld of South China Agricultural University. The nematode ectoparasited and fed on the epidermis cell and root-hair of sugarcanc, decreasing the root number, caustng root necrosis and rot and stunting above-ground. The greenbouse inoculation test showed that the sugarcane yield decreased by 5. 26% to 14.74 % due to the nematode. According to the field plot experiment, the nematicide rugby of 2, 3, 4 andFurandan of 4kg per mu. increased sugarcane yield by 20. 68%, 38. 72%, 23. 17% and 14. 15%respectively.
