1. Preparation of Solution Hydrogen peroxide solution was mixed with water in a ratio of 1:4 and made into a 20% to 25% aqueous solution of hydrogen peroxide with sufficient stirring.
2. Soaking time The prepared hydrogen peroxide aqueous solution is contained in a container, and when poured into the seed, it should be inverted while stirring with a wooden stick so that the seeds can uniformly absorb water. When the temperature is lower than 20°C, the soaking time needs 100-120 minutes; when the temperature is higher than 20°C and lower than 30°C, the soaking time is 60-90 minutes; when the temperature is higher than 30°C, the soaking time is 30-50 minutes. can.
3. Seed germination After soaking the seeds, remove the seeds from the aqueous hydrogen peroxide solution and rinse with water 3 to 4 times (draw the edge and filter the water). After filtering the water, collect it in the container and cover it with a damp cloth. If the seed matures moderately and satisfactorily, generally more than 85% of the seeds germinate within 5 to 6 days, and seedlings can be seeded 2 to 3 days after sowing, which is 6 to 8 days earlier than conventional sowing.
4. Notes One is that before soaking in aqueous hydrogen peroxide solution, the remaining or purchased spinach seeds should be sun-dried in the sunny sun for 4 to 6 hours, and the impurities and insufficient seeds should be removed; the second is to use 100% Bacterial-rinsing water solution is used to sterilize the seeds that have been soaked and germinated; thirdly, the seeds after soaking and germination sterilization should be sowed in time; the soil in Daejeon (greenhouse) is required to be moist; and the fourth one is that after sowing, the cover soil is 1 to 1.5 cm and pressurized. The soil and seeds were matched and covered with straw curtains. When 10% to 15% of the seedlings were unearthed, they were opened.
