我国南方苇区分布于长江中、下游的湖南、湖北、江西、安徽、江苏和上海等省、市。该区长苇面积占全国长苇面积的四分之一,而产量却占全国芦苇总产量的三分之二。该区是以荻为主的生态系,虫害是目前影响该区产量的严重障碍之一。据调查,芦苇害虫多达90余种,其中尤以棘禾草螟Chilohyrax、荻蛀茎夜蛾Sesamia sp.等蛀草害虫的第一代造成的损失较大,芦毒蛾Laelia coenosa candida、高粱长蝽Di-morphopterus spinolae是该区间歇性或区域性暴发的害虫。 芦苇是荻Miscanthus sacchariflorus和芦Phragmites communis的统称。我国现有芦苇面积约40万公顷,年总产量为130万吨左右。目前,芦苇主要作造纸原料用,但供需矛盾十分突出,国家每年尚需花费大量的外汇进口纸张和木浆。此外,芦苇在生
Reed areas in southern China are located in the middle and lower reaches of the Yangtze River in Hunan, Hubei, Jiangxi, Anhui, Jiangsu and Shanghai and other provinces and cities. The reed area in this area accounts for one-fourth of the area of reed in the country, while the output accounts for two-thirds of the total reed production in the country. The area is an ecosystem dominated by Di, which is one of the serious obstacles that currently affect the yield in the area. According to the survey, reed pests up to more than 90 species, of which especially Chilohyrax Spinosrinae, Doth borer Sesamia sp. And other weevil pests of the first generation caused greater loss, the moth moth Laelia coenosa candida, Sorghum long Di-morphopterus spinolae is a pest of intermittent or regional outbreak in this area. Reeds are collectively referred to as Dioscin miscanthus sacchariflorus and Phragmites communis. China’s existing reed area of about 400000 hectares, the total output of 1.3 million tons. At present, the main reed used as raw materials for papermaking, but the contradiction between supply and demand is very prominent, the country still need to spend a lot of foreign exchange each year to import paper and wood pulp. In addition, reeds are born
