在白肋烟生长季节设置逐沟灌、交替隔沟灌、微喷灌3种灌水方式试验,并对3种灌水方式下不同灌水量处理的烟株长势、烟叶产质量、均价及水分利用率等进行了测定。结果表明:微喷灌水量36 mm处理的烟叶产量、产值最高;沟灌灌水量60 mm处理耗水量大,且产量、产值均低于微喷36 mm的处理;微喷灌水量36 mm处理的水分利用率最高。综合烟株生长发育、经济性状及水分利用率,采用微喷方式且灌水量为36 mm的处理生产的烟叶优质且经济效益好。
In the burley tobacco growing season, three kinds of irrigation methods, ie furrow irrigation, furrow irrigation and micro-sprinkling irrigation, were set up. The growth of tobacco plants under different irrigation modes, the yield and quality of tobacco, the average price and the water use efficiency The determination. The results showed that the output value of tobacco with micro-sprinkler irrigation volume 36 mm was the highest, and the irrigation water with 60 mm irrigation capacity was large with the output and output value both lower than those with micro-spray 36 mm. The water use efficiency highest. Comprehensive tobacco plant growth and development, economic traits and water use efficiency, the use of micro-spray method and irrigation volume of 36 mm production of tobacco production and high quality and good economic returns.
