有机无机肥配合施用对烟株生长发育及产质量的影响.

The commercial organic fertilizer was applied with different amounts of inorganic fertilizer in the field experiment. The result showed that the combined application of organic and inorganic fertilizers could improve the field growth of tobacco plants, promote the growth and development of tobacco plants, and reduce the occurrence of diseases to a certain extent. Under the same organic fertilizer level, the yield and output value decreased with the decrease of nitrogen application. From the comprehensive analysis of field performance, agronomic characters, stress resistance and economic indicators, B3 (chemical fertilizer pure nitrogen 97.5 kg/hm2+organic fertilizer 1 800.0 kg/hm2) treatment performed best, followed by B2 (chemical fertilizer pure nitrogen 97.5 kg/hm2), B4 (chemical fertilizer pure nitrogen 90.0 kg/hm2+organic fertilizer 1 800.0 kg/hm2) treatment and B1 (fertilization according to local tobacco farmers habits, chemical fertilizer pure nitrogen 105.0 kg/hm2) ,B5 (chemical fertilizer pure nitrogen 82.5 kg/hm2+organic fertilizer 1 800.0 kg/hm2) showed the worst performance. </span> [ABSTRACT FROM AUTHOR]
