攀枝花烟区氮、磷、钾施肥量对中烟103产质量的影响

Effect on the Dosage of NPK Fertilizer to Yield and Quality of Zhongyan103 Tobacco in Panzhihua Tobacco Production Area

为充分彰显中烟103品种在攀枝花生态条件下的清甜香型品种特性,以"3414"试验方案开展了中烟103品种在攀枝花市烟区的适宜N、P、K的施用量组合试验,并对试验结果进行了验证试验,综合分析了N、P、K施用量对烟株农艺性状、经济性状、品质的影响,确定中烟103品种在攀枝花市供试土壤上适宜施肥量为:N=87.37 kg/hm^2、P=103.57 kg/hm^2、K=353.72 kg/hm^2,此时可获得最高经济产量为Y=3 528.4 kg/hm^2。

In order to manifest Zhongyan103＇s varietal characteristic of slight sweet scent in Panzhihua ecological conditions, ＂3414＂ project is used to study the suitable dosage of NPK fertilizer, and the test results also has been validated. Compared the tobacco＇s main agronomic characters, economic properties and chemistry quality affected by NPK fertilizer, it is confirmed that the suitable dosage of NPK fertilizer were N=87.37 kg/hm2, P=103.57 kg/hm2, K= 353.72 kg/hm2, in this dosage of NPK fertilizer, therefore it is obtained that the maximum economic yield was 3 528.4 kg/hm2.
