摘要
采用均匀设计对黔南惠水烟区覆膜和不覆膜条件下,对烤烟施氮量、种植密度和留叶数调控技术进行了研究。结果表明:惠水山地烤烟覆膜条件下,以施纯氮量105.0 kg/hm2,种植密度1.65万株/hm2,留叶数18～22片为宜;露地栽培条件下,以施纯氮量127.5 kg/hm2,密度1.65万株/hm2(行距为110 cm,株距为55～60 cm),留叶数20～22片为宜。
Adopting the equal design of the covered and uncovered condition of the Huishui tobacco areas in Qiannan Prefeture,the adjustment technology of executing the N amount,the planting density and the amount of the leaves-left were researched.The result showed that in Huishui mountainous area,under the covering condition,tobacco was better to adopt the painting technology of executing N amount of 105.0 kg/hm2,density of 16 500 perhectare,and with 18～22 slices of leaves left.Meanwhile,under the condition of uncovered,it was better to execute the N amount of 127.5 kg/hm2,denstity of 16 500 perhectare（crow distance of 110 cm,individual distance of 55～60 cm）,and with 20～22 slices of leaves left.
