Abstract
To obtain the optimized irrigation techniques of coordinating the internal chemical composition of tobacco and improving the quality of flue-cured tobacco,the effects of optimization of irrigation technology on growth and internal quality of flue-cured tobacco were studied.The results showed that: Such agronomic characters as leaf area per plant were better under each row furrow irrigation and interlacing irrigation treatments than the control;With the increase of irrigation amount,chlorophyll and photosynthetic rates of all treatments increased,SOD and CAT activities showed a general downward trend after topping 15 days and MDA content showed a rapidly increasing trend.Based on the changes of activities of different enzymes,each row furrow irrigation and interlacing irrigation treatments were of good resistance;Economical traits were better under each row furrow irrigation and interlacing irrigation treatments,and with the increase of irrigation amount,hectares of production,output value and average price increased.Concerning mu grams in the value of reducing sugar/nicotine and total nitrogen/nicotine,potassium/chlorine ratio,chemical components under each row furrow irrigation and de-interlacing irrigation treatments coordinated better;Concerning the physical characters of tensility resistance,tensile strength,leaf thickness and filling value,each row furrow irrigation and interlacing irrigation treatments performed better;Total volume of carotenoids,brown reaction product categories,neophytadiene and neutral aroma were higher under each row furrow irrigation and interlacing irrigation treatments.Comprehensively,treatment C of each row furrow irrigation 450 m3/hm2 performed the best at long-term minor drought and in view of water-saving irrigation,treatment B of interlacing irrigation 225 m3/hm2 also promoted the value of the actual at long-term minor drought.
