First, keep soaking off. Before the germination, corn must be soaked, that is, about half of the boiled water and the cool water should be put in small tanks, big pots or other containers, and then the seeds should be put into it. The water surface exceeds the seeds by 20-25 cm. At the same time, use wooden sticks to keep stirring so that the seeds can be heated evenly. The water temperature should be controlled at 25 to 28°C. When the water temperature is lowered, the water should be heated to warm up. So soaking for 2 to 3 hours, when the seeds are water-absorbing, they should be removed immediately for germination.

When soaking, attention should be paid to two technical aspects: First, soaking time can not be too long, so as not to cause hypoxic breathing, reduce the vitality of the seed; Second, pay attention to grasp the water temperature and water. The seeds are rapidly swelled to ensure the quality of soaking.

Second, live germination off. The most suitable temperature for corn germination is about 25°C. After about one day, it can sprout most of the time. At the same time, there must be good ventilation conditions in order to promote seed germination and obtain strong shoots. The specific method of germination is to remove the soaked seeds and control the water, and then place them in a pot or seat, covered with a damp cloth or wet straw bag, and then put on the pods to germinate. Seed heap temperature should be kept at about 20 °C, check the seed temperature every 3 to 4 hours, flip up and down once to adjust the air temperature, the temperature is too high or too low when the venue must be moved at any time to adjust the temperature. When the seed has 40 to 50% of the mouth began to open white, you can pick the bud seeding. The germinated seeds can be germinated after repeated germinations of 2 to 3 times with germinating seeds washed once with warm water.

Two problems should be noticed when germinating: First, after seed germination, timely sowing should be done. If not sowing, the germinated seeds can be placed at 2～4°C to control seedling sprout growth, but the date cannot be Too long; the second is to pay attention to the germination temperature, it is best to do a small amount of seed test, to be obtained after the experience of formal germination, so as not to cause undue losses.

Third, the live sowing off. The soaking, germination and sowing of corn must be closely linked and not disconnected. The technical aspects of corn germination should be noted: First, pick the seeds to sow, and select the seeds that have just been screwed to expose the white seeds, remove the seeds that are germinating too long, yellow, and two to make sure that the seeds are strong; the second is to be timely Seeding, germination of seeds can not be sown early, sowing because of low ground temperature, will delay the emergence of small seedlings, resulting in uneven seedlings and the consequences of seedlings are not strong. When the local temperature is stable at around 10°C, sowing is the most advantageous. Third, when sitting on water, it is necessary to water first, then put the seed after the water sinks, and timely cover the soil and step on the foot; Do not grind the pit too deep and cover soil too thick. Generally, it is not more than 5 cm.

Long Range LiDAR Radar
