If the watermelon seeds have germinated, then this time is to lay a good seedbed for the seeds, and the seedlings suddenly need enough nutrients. Seed seedlings will generally use a special plastic small grid, generally a hole inside a seed. Then seal the plastic cells with fertile soil.

Because there is uncertainty about the temperature in March, in order to keep the seeds growing at a constant temperature, they must be covered with plastic film and covered with soil to prevent them from being blown away by the wind. At the beginning, the temperature inside must be controlled above 20 degrees Celsius. After the seeds sprout, the watermelon seedlings can slowly get used to the natural temperature, and finally the plastic film can be completely removed.

2. Watermelon seedling transplantation

After the watermelon seedlings grow up, they should immediately start preparing for transplantation. The base fertilizer of the soil before transplantation is very important. In rural areas, fermented cow dung and compound fertilizer are generally used to put them at the bottom. One seedling is placed at each position. Finally, watering is carried out. The watermelon seedlings are wrapped with straw to prevent freezing. To be on the safe side, each watermelon seedling must be covered with plastic film with bamboo sticks. After the watermelon seedlings begin to stretch, the natural temperature will basically stabilize at this time, and the plastic film can be removed.

Watermelon seedlings grow slowly in the early stage, so we should water them frequently. After the watermelon seedlings extend, in order to prevent the vines from over-growing, we should not over-fertilize them, which can pave the way for fruit setting later.

The above is the introduction of watermelon, watermelon want high yield, must choose excellent watermelon varieties. Friends who want to plant watermelon can master the above seedling methods to achieve the goal of high yield.
