If the seedlings are released prematurely, there is an effect on the non-emerging cotton buds due to running chills, and the time for seedling emergence is extended to form large and small seedlings. Second, it is best to put green seedlings, that is, the cotyledons have been developed cotton seedlings, do not put yellow seedlings, otherwise easy to be sunburned.

3. When the seedlings are put on the membrane in time, the membrane mouth should be buried in a timely manner with fluvo-aquic soil to prevent air leakage, running rancid, and weeds, which will affect the growth of cotton seedlings. What's more important is to prevent the wind from uncovering the film.
