当今的日本,农用地膜的使用不仅在蔬菜上非常普及,而且在其他农作物上也已普遍应用。现就日本农用地膜发展概况、现有各种农用地膜特性、地膜加工及应用前景作一介绍。 一、发展史简述 1951年,日本首次进口了聚乙烯塑料原科,当时并非用于农业。但当农民把已用过的旧薄膜用来作天膜或地膜使用时,结果发现其具有使作物生长发育快,提早收获等许多优点,于是在1955年,首次在静冈县进行了草莓地膜栽培试验。随后,在洋葱、番茄、黄瓜等蔬菜生产中也成功地进行了地膜栽培试验。到1958年,随着聚乙烯原料国产化,原料成本大幅度下降,薄膜加工技术迅速发展,从而使塑料薄膜能够在番茄、黄瓜,草莓等怍物的实际栽培中普及应用。
In today’s Japan, the use of agricultural film is not only very common in vegetables, but also in other crops. Now on the development of agricultural plastic film in Japan, the existing variety of agricultural plastic film, plastic film processing and application prospects for an introduction. First, a brief history of development In 1951, Japan imported polyethylene plastic for the first time the original subjects, was not for agriculture. However, when farmers used the old film as a film or film, they found that they had many advantages such as quick growth of crops and early harvesting. Therefore, in 1955, the first time in Shizuoka, strawberries were made Cultivation test. Subsequently, in the onion, tomato, cucumber and other vegetables in the production of mulching has also been successfully conducted experiments. By 1958, with the domestication of polyethylene raw materials, the cost of raw materials dropped drastically and the film processing technology developed rapidly, so that the plastic film could be popularized and applied in the practical cultivation of tomatoes, cucumbers and strawberries.
