随着农业技术的飞快进步,要求工业部门提供的新型材料也就日益迫切。塑料由于可制得具有许多优良性能的制品,因此,目前国内外的农业工作者正在把注意力更多地转向选择塑料材料,让其更好地为农业现代化服务。为此,在这里向读者介绍几种新型农用塑料材料。 1.阻隔紫外线的遮阳用的多功能棚膜熟悉农业的人都知道,夏季栽培一些作物(如西红柿、大椒、黄瓜等)是比较困难的。露地栽培和使用普通透明薄膜栽培,往往结不了果或多出现病果和畸形果。根据国外的资料报导,夏季气温高,同时紫外线照射强烈。紫外线可以使土壤中增殖细菌孢子,这些 With the rapid advancement in agricultural technology, the demand for new materials from the industrial sector has also become increasingly urgent. Plastics Because of the availability of products with many excellent properties, agricultural workers both at home and abroad are now turning their attention more to the selection of plastic materials to better serve their agricultural modernization. To this end, to introduce readers to several new agricultural plastic materials. 1. UV-blocking sunscreen with multi-functional film Familiar with agriculture all know that the summer cultivation of some crops (such as tomatoes, peppers, cucumbers, etc.) is more difficult. Open-field cultivation and the use of ordinary transparent film cultivation, often can not bear fruit or more disease and deformities fruit. According to foreign data reported that the summer high temperature, while strong ultraviolet radiation. Ultraviolet light can make bacterial spores proliferate in soil, these
