Abstract:

By applying different mixtures of sesame cake fertilizer and chicken manure, the changes of quality and economic benefit of flue-cured tobacco were studied. The results showed that pure sesame cake fertilizer was not conducive to the early growth and rapid development of tobacco plants, the mature period was delayed, the growth period was extended, and the agronomic characteristics, economic benefits and chemical composition coordination were poor. In the experiment, 1125 kg/hm² chicken manure organic fertilizer combined with 375 kg/hm²sesame cake fertilizer had the best effect, which could improve the yield and quality of flue-cured tobacco, promote the growth of tobacco plant in the middle and later period, and increase the yield, output value, average price and ratio of high grade leaves. The application of sesame cake fertilizer could inhibit tobacco mosaic virus and tobacco bacterial wilt, and was harmful to control tobacco brown leaf spot.
