芝麻饼肥与鸡粪有机肥不同混用量对烤烟生长、质量和经济效益的影响

Effects of Different Mixtures of Sesame Cake Fertilizer and Chicken Manure Organic Fertilizer on Growth, Quality and Economic Benefit of Flue-cured Tobacco

本文在常规施肥的基础上配施芝麻饼肥和鸡粪有机肥,研究不同混用量对烤烟生长、质量和经济效益的影响。结果表明:纯施芝麻饼肥不利于烟株早生快发,烟株成熟期推迟,生育期延长,且大田农艺性状、经济效益与化学成分协调性均较差。本试验中,1125 kg/hm^(2)的鸡粪有机肥,配施375 kg/hm^(2)的芝麻饼肥,效果最好,可改善烤烟的产量和质量,对烟株中后期生长有明显的促进作用,可提高烟叶产量、产值、均价和上等烟比例。施用芝麻饼肥对花叶病与青枯病有抑制作用,对抗赤星病不利。

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/hm^(2)chicken manure organic fertilizer combined with 375 kg/hm^(2)sesame 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.
