1.温汤浸种 2份开水,加一份凉水,倒入种子,搅拌10-15分钟,使其自然冷却,浸种4-6小时,即可催芽播种。此法可预防西瓜、甜瓜花叶病毒病。2.高温烫种一边放开水盆,一边放凉水盆,水量为种子量的3倍,种子先倒入开水中,迅速搅拌3-5秒钟,立即将另一容器中的凉水倒入开水中,使水温下降,不断搅拌10-15分钟,然后浸种3-4小时,即可催芽或播种。注意速度要快,不要烫得时间太长,以免影响种子的发芽率。此法可杀死种子表面的病原菌。3.干垫消毒先在烘箱中用40℃预烘烤4小时,然后在70℃烘5天后播种。此法可杀死种子携带的病毒。4.强光晒种在春季,选择明朗无风天气,把种子摊在席子上,厚度不超过1厘米,使其在阳光下暴
1. Wen Tang soaking 2 parts boiled water, add a cold water, pour the seeds, stirring for 10-15 minutes, allowed to cool naturally, soaking seed 4-6 hours, to germinate sowing. This method can prevent watermelon, melon mosaic virus disease. 2. High-temperature hot kind while letting go of the basin, while putting the chiller, the amount of water 3 times the amount of seeds, the seeds first into the boiling water, stirring rapidly 3-5 seconds, immediately pour the cold water in another container into boiling water , So that the water temperature dropped, stirring constantly 10-15 minutes, and then soaking 3-4 hours, you can germination or sowing. Note that faster, do not get too hot for too long, so as not to affect the seed germination rate. This method can kill the seeds of the surface of the pathogen. 3. Drying pad disinfection pre-baking in the oven at 40 ℃ for 4 hours, then baked at 70 ℃ for 5 days after sowing. This method kills seed-borne viruses. 4. Strong sun in the spring, the choice of clear windless weather, the seeds spread on the mat, the thickness of not more than 1 cm, making it in the sun
