烤烟是我县重要的经济作物,常年种植面积7万亩左右,总产2100万斤,总收入2522万元,占全县农业总产值的32.3％左右。自七十年代以来,随着粮食产量的不断提高,土壤中含氮量逐年增多,造成烟叶商品等级下降,内在品质差。为了提高烟叶品质,开创我县烟叶生产新局面,我们于一九八二年——一九八四年在省、地“烤烟优、稳、低协作组”的指导下,开展了“烤烟优、稳、低栽培技术措施的试验”。三年来,经过小面积试验和大面积综合栽培技术措施的示范应用,摸索出了提高和改善烟叶品质的几项主要技术措施,并取得了较显著的效果。现将试验示范结果报告如下:
Flue-cured tobacco is an important cash crop in our county. The annual planting area is about 70,000 mu with a total output of 21 million kilos. The total income is 25.22 million yuan, accounting for 32.3% of the total agricultural output value of the county. Since the seventies, with the continuous increase of grain output, nitrogen content in soil has increased year by year, resulting in the decline of tobacco product grade and poor intrinsic quality. In order to improve the quality of tobacco leaf and create a new situation of tobacco leaf production in our county, under the guidance of “excellent, stable and low-yield tobacco flue-cured tobacco” from 1982 to 1984, , Steady, low-cultivation technical measures of the test. " In the past three years, through the demonstration and application of a small area test and large-scale comprehensive cultivation techniques and measures, several major technical measures for improving and improving the quality of tobacco leaves have been explored and achieved remarkable results. Now the pilot demonstration results are reported as follows:
