Growth characteristics of watermelon covered with plastic film

The root system of watermelon covered with plastic film has strong ability of fertilizer absorption, fast growth and early development, which is easy to cause premature senescence, so we should pay attention to the application of topdressing. Because the plastic film has a good effect of preserving soil moisture and less water requirement of seedlings, the times and amount of irrigation can be reduced appropriately in the early stage. The maturity of watermelons covered with plastic film is earlier, and the climatic conditions are still more suitable for the growth and development of watermelons after the first harvest. The specific method of selecting the second stubble melon is to leave a female flower on the side vine of the watermelon plant when the first stubble melon is basically fixed (about 7-10 days before harvest).
