Research on Var.Italical Planch Cultivation Covered with Plastic Film in Early Spring

The earth-membrane covered technique of Var. italica planch early spring can improve the cultivated land temperature 1～2?℃,benefit to the development of plants, enlarge the index of plants such as height and width of stalks and strech, as well as the flower-like balls, compared with the traditional cultivation model. The supply index of the choices infected by pests reduced 84.7%, which made the supply time be ahead of the average 4 to 6 days, covered with production notably.
