摘要
为解决当前烟叶原料供需间的等级结构和部位结构矛盾,探索了兴烟1号优化烟叶结构的效应。结果表明:与常规生产相比,兴烟1号可在不影响烟叶质量的情况下,增加中部烟叶比例23.18%,分别减少上部和下部烟叶比例17.46%、4.25%;上中等烟叶比例达93.79%,增加幅度为7.24%;增加产量660.30㎏/hm2,产值增加了11 433.60元/hm2,达到了提升烟叶结构和增加经济效益的目的。
To solve the problems that structures of grade and plant position in current tobacco supplies and demands, this article has probed into effects of tobacco leaf structure by adjustment of growing techniques of Xingyan 1. The results show that： comparing to normal growing techniques, Xingyan 1 can increase middle stalk leaf by 23.18%, decrease upper and lower stalk leaf by 17.46 and 4. 25% respectively; high and medium grade leaf account for 93.79%, which increased by 7.24% ; and yield increased by 660. 30 kg/hm^2, total income increased by 11433.60 yuan/hm^2, without any effect to leaf quality. These have achieved improvement of leaf structure and increases of economic benefit.
