摘要
试验利用多肽保处理苗期和大田期烟草,探究其对烟草的影响.结果表明:烟草育苗时,12盘基质中均匀拌入188 g(即1 875 g/hm2)多肽保,对出苗率的影响最小,同时能提高烟苗成苗率及烟苗素质,有效提高烟草苗期对黑胫病、根黑腐病及病毒病的抗性;大田移栽时和移栽15 d后分别以750 g/hm2和2 250 g/hm2的量塘施多肽保,能够有效控制大田黑胫病和根黑腐病的发生,提高烟叶的产量和质量.
Flue-cured tobacco is tested by using dry mycelium of Penicillium chrysogenum (DMP) during seedfing-stage and field peri- od to study the impact. The results showed that 12 disc the nursery matrix are even mixed with 188 g (i. e. 1 875 g?hm2) DMP during the tobacco seedling stage which got the minimum influence on seedling emergence rate and improved living percentage and quality of tobacco seedlings. And there is evidence that DMP treatment can improve the resistance in tobacco seedling stage against black shank, black root rot and virus disease. In the field period and 15 days after transplanting, 750 g/hm2 and 2 250 g/hm2 DMP were used re- spectively, it can effectively control black shank, black root rot and virus disease and improve the production and quality of tobacco leaf.
