施用海洋生物制剂农乐二号对烤烟的影响

Effects of Nongle 2,a Marine Organism Agent,on Yield and Quality of Tobacco

研究了海洋生物制剂不同施用方法、施用浓度对烟叶产量和性状的影响。结果表明，农乐二号可提高烟叶产量8．75～15．44kg／667m^2，提高上等烟率3．38％～9．76％，产值增加108．14～177．96zL／667m^2，且具有显著的抗病抑菌作用，烟叶内在质量和化学成分有所改善，烟叶接近优质烟要求。施用方法以喷施为主，可以灌根，喷施浓度200-300倍液，施用量50-100L／667m^2，灌根用量150L／667m^2。

Nongle 2, a marine organism agent, was tested in tobacco to study the effects of different application method and concentration on tobacco yield and quality. The results show that the agent can increase by 8.75 - 15.44 kg/667 m^2 of tobacco yield, by 3.38%-9.76% of first tobacco rate and by 108. 14-177.96 Yuan/667 m^2 of output value, and improve tobacco quality and chemical composition. The application methods should take the spray method as the dominant factor. The spray concentration is 1 ： 200-300 and the spray application amount is 50 -100 L/667 m^2. The rooting application amount is 150 L/667 m^2.
