After germination of the corn seeds, dig a 20 cm deep soil trough in the sunny side of the courtyard (length and width are self-determined as required), and pour the sawdust and fine sand (3 parts of sawdust and 1 part of fine sand) in the trough. 10 cm thick. After the top layer is leveled, pour with warm water 1 time, put 1st corn seed after germination (preferably not to overlap), then spread the sawdust and fine sand mixed in proportion on top. The groove is arched with bamboo or wood strips to cover the plastic film. Early bed temperature should be maintained at 25 ~ 30 °C, if the temperature is too high ventilation and cooling at any time; late attention to the temperature, if the seedbed water can be poured in time of 16 °C warm water, can also be applied 1% to 2% of urea water or three Fertilizer, promote seedling growth and rejuvenation. When the corn seedlings grow to 1 to 2 hearts, you can apply enough base fertilizer on the whole land and transplant them at the right time. If the moisture content of a well-behaved plot is more than 25%, it is not necessary to water it during transplanting, and the plot with a water content below 20% needs to be watered.

The benefits of transplanting corn without soil are the advantages of saving seeds, keeping seedlings and benefiting. The amount of 667 m2 used was 1-3 kilograms, more than 50% of that in the live province, and the seedling preservation rate was 99.7% after transplanting. And because the seedlings grew in the bed, the accumulated temperature was 200-250°C, which increased the growth period and matured more than 10 days in advance. The increase was significant.
