The Status Quo of Film Application and Residue in the Southern Plains of China
摘要
Abstract
With the application of mulching film technology since 1970s, a large amount of mulching film was accumulated in the field. Pollu-tion of mulching film has become more and more serious because its material is difficult to degrade bio-chemically. In this study, the authors adopted the methods of document research, questionnaire and typical sample collection to find out the present situation of film use and film residue in the Southern Plains of China. The studies showed that, the use and coverage of film was increasing year by year. The proportion of film coverage to total arable land also leaded an increasing trend, but less than 10%. There were four main categories of crops(i.e. strawberry, peanuts, cotton and vegetables)including nineteen kinds of crops covered by plastic film. The average ratio of area film was 74%. The aver-age of thickness used in agriculture was 0.006 mm, and the average amount was 38.6 kg·hm-2. In addition, most of land(73.1%)had recycled the film after they have been used. The hand picking was the main ways of recycling, but combining the hand picking and machine recycling was also used in a few lands. The weight of film residue in the soil of 0~30 cm was 14.28 kg·hm-2, and the residue film was mainly in the soil of 0~20 cm, almost occupied 78.9%of total residue film in the soil of 0~30 cm. Film recycling was a significant factor that affectted the weight of film residue in soil, and the weight in the recycled field was less than the one in the unrecycled field significantly. If unrecycled, the weight of film residue had a significantly positive relation with the total amount of mulching film used in agriculture. However, if recycling, the total amount of mulching film had little effect on the weight of film residue.关键词
