烟草作为高效农业的一个品种,一般亩产值在1—2千元之间;防风作为药材的一个紧缺品种一般亩产值2000元以上。若将二者套种,不仅解决烟药争田的矛盾,又能将单产成倍提高,经济效益成番增长,是发展“两高一优”农业的一种好模式,尤其适用于烟叶产区。烟田套种防风,主要解决好二者之间对氮肥需求上的矛盾。施用过 As a variety of high-efficiency agriculture, tobacco generally ranges from 1 to 2,000 yuan per mu; and wind-blown as a shortage of medicinal herbs, the average output value per mu is more than 2,000 yuan. If the two are interplanted, not only to resolve the contradiction between tobacco fields, but also to double the yield per unit area, economic growth into a double, is the development of “two high and one excellent” agriculture is a good model, especially for tobacco production areas . Tobacco intercropping windbreak, mainly to solve the contradiction between the two needs of nitrogen fertilizer. Used
