烟草半覆膜栽培技术是覆膜方法的一种改革.目前普遍采用的全覆膜方法,虽然烟草的产质量有增加,但成本却较高,不利于扩大栽培面积.采用半膜覆盖成本可降低25%左右,而增产增质效果与全膜覆盖无明显差异.同时,半膜覆盖还利于追肥和管理.具体方法如下:1.整地做垄.移栽前翻地,施足粪肥.施肥一般采用条施方法,上肥地块每亩施入纯氮3—4公斤,中肥地每亩施4—5公斤,低肥地亩施5—6公斤为宜.氮、磷、钾比例按土质和茬口而定,生茬地和薄地其比例以1∶1∶2为宜;重茬
Half-film tobacco cultivation technology is a reform of the coating method.Currently used full-coating method, although the quality of tobacco production has increased, but the cost is higher, is not conducive to expanding the cultivation area.With the semi-membrane coverage costs Reduce about 25%, while the effect of increasing production and increasing the quality of the whole film coverage no significant difference.At the same time, the semi-film coverage is also conducive to dressing and management. Specific methods are as follows: 1. Land preparation ridge. The general method of applying the method, the fertilizer block per acre applied to pure nitrogen 3-4 kg, medium fertilizer 4-5 kg per acre, low fertilizer Mushi 5-6 kg is appropriate. Nitrogen, phosphorus and potassium ratio According to the soil and stubble, the proportion of stubble field and thin to 1: 1: 2 is appropriate; stubble
