In order to explore the impact of plastic film mulching cultivation on cucumber growth and development, in 1983 we Pinglu County Chengguan commune team of four trials, the test results are summarized below. First, the experimental design and processing experiments set wide ridge (70 cm) double row planting cover film and narrow ridge (25 ~ 30 cm) single row cover film two treatment, respectively, wide and narrow ridge exposed cultivation as a control. Not set to deal with the cell alone, only the set point, given observation. Repeated three times, 24 plants were planted repeatedly and 6 plants were observed by fixed point. Observed every 5 days from transplanting to the end of the whole growth period. The test varieties Ning Huang One. Test before the crop in tomato, autumn plowing twice, shrubs
