摘要
1989年和1990年两年4因素3水平多点联合正交试验结果表明,烤烟品种K326,G80,K394在湖南各地种植表现均佳,尤以K32e表现最好,特别适宜湘南主产烟区种植:单株留叶数以16~18片为宜;在N:P_2O_5:K_2O为1:1:2的条件下,每公顷施纯氮150~180kg,可望获得优质适产(2250~2650kg/ha);在追肥占总施肥量60%的条件下,栽后40~50d之内将追肥分3~4次施下可望获得较好效果.
A 2-year(1989~1990) study was conducted to determine the effect of cultural factots on the economic charactets of flue-cured tobacco (Nicotiana tobacum L.) in Hunan Province, The results indicated that the optimal combination of agronomic measures for high quality and moderate yield (2250~2625 kg/ha) is. Cv. K326, the number of leaves left on the plant 16~18, the rate of application N 150~l80 kg/ha,nitrogen, phosphorous, and potash in rations of 1:l:2, the date of top application 3~4 times within 40~50 days after transplanting.
