Seed germination is the most important part of vegetable production, and it is an important technical measure for nursery and cultivation. It can not only make the seeds germinate neatly and shorten the seedling age, but also can improve the quality of the seedlings and ensure the seedlings grow robustly. For many years, the author carried out electric blanket sprouting on vegetable seeds and received an ideal result. The method of germination of electric blankets is introduced as follows, for reference for farmers to learn and apply.
?? 1, seed disinfection In order to improve seed vigor, promote germination, prevent pests caused by seeds and cause pest damage, pregermination should be disinfected seed treatment, the main methods are hot water and chemical seed soaking two kinds. 1 Hot-water hot seeds: Wash the seeds with hot water before hot-skinning, and then hot-steam for 10-15 minutes with 55-600C hot water. Be careful to stir the seeds while they are hot to make the seeds evenly heated. 2 Pharmaceutical soaking: Soaking for 1 hour with water before soaking, soaking with liquid, soaking with 0.1%-0.35% potassium permanganate solution for 20 minutes or soaking with 1% copper sulfate, 2% sodium hydroxide solution 5- 15 minutes soaking with 0.2% of 50% carbendazim for 20-30 minutes or 0.125 metalaxyl soaking for 30 minutes or soaking with 0.1% of 60% anti-mildew plus 0.1% leveling solution for 60 minutes.

Or wool and other cover insulation, after the completion of coverage of electricity; sooner or later each day with a towel wrapped seeds for washing, draining and then continue to electric blanket germination until the seeds germinate.
??4, the scope of application 1 applies to beans, cowpea, watermelon, bitter gourd, cucumber, eggplant, pepper, jade and other seeds of germination; 2 apply to a large number of seeds, small and medium-sized farms, watermelon base and other germination, seedlings.
?? 5, Note 1 hot water must be constantly stunted, so as not to burn, burn the seeds; 2 to operate when the power is off, after the completion of power; 3 seed germination and more than 50% when the sowing time .
