化肥配施不同有机肥对土壤养分释放及烤烟养分吸收的影响
Effect of Combined Application of Different Organic Manure and Chemical Fertilizer on the Soil Nutrient Release and Nutrient Absorption Characters of Tobacco
摘要
Abstract
In order to guide fertilization for flue-cured tobacco production, this experiment analyzed the characters of the soil nutrient release and nutrient absorption of tobacco under the combined application of different organic manure and chemical fertilizer in Jingxi and Nandan of Guangxi provicece. Results showed that the yield and economic value of flue-cured tobacco treated with organic manure+chemical fertilizer were not significant but improved by 4.6 ％-15. 5 ％ and 92.3％-106.7％ in Jingxi and 0. 06％-32. 4％ and 65.7％-97.8％ in Nandan respecitively compared either with chemical fertilizer or with local recommend fertilizer. Moreover, the total K,total N,total sugar and reducing sugar of tobacco increased with Nicotine discreased. N/nicotine and sugar/nicotine ratio is more close to 0.8-0.9 and to 10 than those with chemical fertilizer. Soil nitrogen released slowly at the early stage after applying organic manure and chemical fertilizer but lasted longer. The supply of soil available P and K nutrient, and nutrient absorption of tobacco significantly improved, e.g. the total N and total P of tobacco increased by 8.6％3-61.5％ and 2.9％-34.3％ respectively at the end of the stage. The treatment of applying 40％ peanut bran and 60％ chemical fertilizer was a better fertilizing model because the best soil fertility, tobacco yield, quality, and nutrient can be reached under this fertilizing model. Correlation analysis showed that soil available nutrient had positive correlation with tobacco nutrient and with tobacco quality, indicating that soil fertility, tobacco nutrient and quality were synchronized after appling organic manure and chemical fertilizer.关键词
