Effects of bio-organic fertilizer's application on flue-cured tobacco planted on continuous cropping soil
The effects of compost mixed with earthworm fertilizer and effective microorganism on continuous cropping soil was studied. It discussed the effects of bio-organic fertilizer and chemical fertilizer's mixing application by different ratios on fluecured planting and the soil chemical properties with pot experiment. The result indicated that: the fertilization significantly promoted the growth of flue-cured tobacco, the best proportion of bio-organic fertilizer was fifty percent, followed by seventy percent, while the yield of flue-cured tobacco was the highest when the proportion was fifty percent, the growth and yield of flue-cured tobacco of pure bio-organic fertilizer treatment was better than pure fertilizer treatment, the bio-organic fertilizer could promote the nitrogen and potassium absorption when the proportion was between thirty percent and fifty percent, and was more propitious to the production of high quality tobacco, the application of organic fertilizer could significantly increase the cropping soil's pH, organic matter content and available nitrogen, phosphorus and potassium content.
