Vegetables such as watermelon, tomato, cucumber, cowpea and sweet pepper are covered and mulched with plastic film, showing early maturity, increased yield, increased income and earlier market .This is covered by plastic film and can play a role of warming, The main points of cultivation techniques are as follows: 1.Select precocious varieties and sow early selection of vegetables with higher economic value, such as bell peppers, tomatoes, cucumbers and other precocious varieties in order to give full play to the early plastic film mulching growth and earlier than normal 1 ~ 2 weeks sowing .2 early tillage, wetting and tidy is the foundation of plastic film mulching cultivation, the quality of the soil preparation directly affects the effect of coverage .Therefore, we must turn ahead in advance, as early as the spring turn, turn with the rake, Rake fine soil
