研究了不同移栽期对巧家烤烟生长发育和产质量的影响,旨在找出巧家烤烟种植的适宜移栽期。研究结果表明:从4月20日到5月14日,随着移栽期的推迟,烟株的生育期缩短,生长发育加快;株高、叶片数、腰叶长宽和腰叶面积各处理之间差异显著;产量、产值、均价和上等烟比例都有减小的趋势;化学成分和内在质量以4月26日、5月2日和5月8日移栽的表现较好。建议巧家的移栽期宜排在4月底至5月初。
The effects of different transplanting periods on the growth, yield and quality of Qiaojia flue-cured tobacco were studied in order to find out the appropriate transplanting period for Qiaoji flue-cured tobacco planting. The results showed that from April 20 to May 14, with the delay of transplanting period, the growth period of tobacco plants was shortened and the growth and development accelerated. The height, number of leaves, length of lumbar and leaf area, The difference was significant; the yield, the output value, the average price and the proportion of the superior tobacco tended to decrease; the chemical composition and internal quality performed better on April 26, May 2 and May 8 transplanting. Suggest clever transfer should be arranged in late April to early May.
