正确、有效地处理种子上的有害物,是防治蔬菜病害的一大途径。 1.温汤浸种:把待消毒的种子浸泡在一定温度(一般50～55℃)的恒温热水中,保持一定时间后取出种子。也可结合栽培上的浸种催芽一道进行。温汤浸种适于对侵入并寄生于种子的病原菌进行防治。由于杀菌的有效温度和浸种产生发芽障碍(伤害种子)的临界温度接近,所以采用此法处理时需严格控制温度和时间,以下是几种主要蔬菜种
Correct and effective treatment of the seeds of the pests, is a major way to control vegetable diseases. 1. Wen Tang seed soaking: the seeds to be disinfected in a constant temperature (usually 50 ~ 55 ℃) constant temperature hot water, to maintain a certain time after the removal of seeds. Can also be combined with the cultivation of seed soaking germination. Wen Tang soaking suitable for invasive and parasitic seeds in the prevention and treatment of pathogens. Due to the effective sterilization temperature and seed soaking germination (damage seeds) critical temperature close, so using this method requires strict control of temperature and time, the following are several major vegetable species
