通过近三年来一系列的突验观察,进一步肯定麦种用石灰水消毒处理对各种种子传播性病害有完全的防治效果。操作得好,还起增产作用。炎夏短时间处理(37℃左右半天,35℃左右1天,30℃左右1.5天)与深秋长时间处理(25℃左右2.5天,20℃左右5天)效果相同。为了便于种子干燥,宜尽早于夏季处理。麦种浸水后阴干阳干均无不可,但必须充分干燥,以免貯藏中减弱种子生活力影响发芽。麦种在夏季处理,发芽力会显见降低,这是暂时现象,貯放一定时期后,仍能逐渐恢复活力。为了防止土壤和肥料传病,石灰水浸麦种干燥后,还可以再行 HCB 拌种或油粕粉末混播。
Through a series of emergent observations in the past three years, it is further confirmed that the wheat seed with lime water disinfection treatment has a complete prevention and control effect on various seedborne diseases. Well done, but also play a role in increasing production. Short treatment in summer (about half a day at 37 ℃, 1 day at 35 ℃, 1.5 days at 30 ℃) is the same as that of the late autumn (2.5 days at 2.5 days and 5 days at 20 ℃). In order to facilitate the drying of seeds, should be dealt with as early as possible in summer. After the wheat is soaked in water, dry and dry are all acceptable, but it must be fully dried so as not to affect the viability of the seeds during storage. Wheat seeds in the summer processing, germination will be significantly reduced, this is a temporary phenomenon, after a certain period of storage can still gradually restore vitality. In order to prevent the transmission of soil and fertilizers, lime water immersion wheat species can also be re-HCB seed dressing or oil meal mixed.
