四川什邡晒烟是著名的传统特产,常年种植面积七、八万亩,年产烟叶20余万担。为了进一步提高质量,特提出以下四点意见。一、控制氮肥,增施磷钾肥是提高晒烟质量的关键。据1981年皂角公社六大队三队增施磷钾肥提高产质的试验,每亩增施纯磷6.9斤,钾22.1斤,平均单产243.2斤(一季头烟)。比未增施磷钾肥的单产134斤(一季头烟)增产81.3%。品质也大有提高(灰白、接火、味纯)。县农场今年亩增施纯磷2.4斤,钾10.02斤,平均单产353.9斤(一季头烟),比未增施磷钾肥的亩产301斤(一季头烟)增产17.5%。品质也有较大提高。上述试验结果表明,增施磷钾肥对晒烟增产增质有着重要的作用。建议今后
Sichuan Shifang Zhanyan is a famous traditional specialty, perennial planting area of seven or eight acres, with an annual output of more than 20 million Tam. In order to further improve the quality, put forward the following four points of view. First, the control of nitrogen fertilizer, phosphorus and potassium fertilizer is the key to improving the quality of sun-cured tobacco. According to the 1981 Gallbladon Commune Brigade three teams to increase phosphorus and potassium fertilizer to improve production quality test, per acre added pure phosphorus 6.9 kg, potassium 22.1 kg, the average yield of 243.2 kg (a quarter of the first cigarette). This is an increase of 81.3% over the yield of 134 kg (first-quarter) of tobacco that did not increase phosphorus and potassium. Quality is also greatly improved (gray, then the fire, taste pure). This year, the county’s farmland increased the output of pure phosphorus by 2.4 kg and potassium by 10.02 kg, with an average yield of 353.9 kg (first-quarter tobacco) and an increase of 17.5% over the output of 301 kg (first-quarter tobacco) per mu without phosphorus and potassium fertilizer. Quality has also been greatly improved. The above test results show that the increase of phosphorus and potassium fertilizer on sun-cured tobacco production and increase quality plays an important role. Suggest future
