Vegetable seed temperature changing method

Some vegetable seeds are subjected to temperature change during germination. The temperature-changing treatment in the germination of vegetable seeds is a kind of temperature treatment method which uses a high temperature and a low temperature to alternately change the germinating seeds. The specific approach is: The germinating seeds are placed at a low temperature of l~5°C for 12 to 8 hours each day and then placed at a higher temperature of 18 to 22°C for 6 to 12 hours. This is repeated until the germination is completed. The seed undergoing variable temperature exercise can adapt the germplasm's protoplasmic viscosity to the change of low temperature, and the water holding capacity of the protoplasm increases, so it can enhance the cold resistance of the thermophilic vegetable seedlings such as melons and solanes and make the seed germinate and thick. Accelerate the growth and development rate, so that early growth period; especially the seedling root system to enhance the ability of resistance to low temperature, and then improve the fruiting period of melon and fruit vegetables, improve early yield.
