How to plant seedlings in watermelon cultivation with plastic film mulching

There are two methods when transplanting melon seedlings covered with plastic film: one is to plant the seedling first and then cover the film after the seedling is planted, tear the plastic film above the melon seedling and pull out the melon seedling, and press the plastic film with wet soil around the seedling; the other is to cover the film first and then plant the seedling. Use the soil sampler to hit the seedling hole on the plastic film according to the plant distance (pay attention to the soil sampler should be bigger and deeper than the nutrition bowl, avoid standing the nutrition bowl when planting seedlings). The advantage of covering the film first is that the film mulching is faster, the ground temperature is raised early and good, and the weeding effect is good, and the seedling planting process can be done separately, which can improve the seedling planting efficiency.
