What are the five ways to accelerate germination of watermelon seeds?

Before sowing, choose sunny and windless weather, spread the seeds on straw mats, cloth bags, sacks or paper, with the thickness not exceeding 1 cm, expose them to the sun for two noon hours, and turn them over every 1 hour to make them receive light evenly. Sundrying seeds can not only kill bacteria, but also improve the germination rate of seeds.

2, seed disinfection

If the seeds are scalded with warm water at 55℃, the water consumption should not exceed 3 times of the seeds. After pouring the seeds, stir for about 30 minutes while soaking, and stop when the water cools. This method is easy for some melon farmers to burn seeds without germination, so be careful when using this method.

Step 3 soak the seeds

Soaking time is related to seed coat thickness and water temperature among varieties. The soaking time of big seeds with thick seed coat is longer, while that of small seeds with thin seed coat is shorter. The soaking time of old seeds or dry seeds is longer, otherwise it is shorter; When soaking seeds, the water temperature is low and the soaking time is long, and vice versa. The general soaking time is 8- 12 hours.

Step 4 accelerate germination

This method is the safest and most reliable because there is an automatic temperature control device, which can control the constant temperature. When accelerating germination, first adjust the control panel or knob to an appropriate scale, generally 28-30℃. Turn on the heating switch. Then put wet gauze or wet towel on a plate or other container, spread the seeds on the wet gauze, and finally put the plate in an incubator to accelerate germination.
