摘要
[目的]比较4种不同种类的腐殖酸水溶性有机肥在楚雄烟区烤烟上的“减肥、提质、增效、降本”效果。[方法]进行了施用4种不同种类腐殖酸水溶性有机肥减少化肥用量30%的处理与常规施肥对照的小区试验。[结果]烟株主要农艺性状和地上地下部分干鲜重甲壳素水溶肥优于其他水溶肥处理和对照处理,产量和腰叶单叶重最高的是“YD-3”全效腐殖酸水溶性有机肥分别为3031.05 kg/hm^(2)和10.14 g;产值和均价最高的是济农含腐殖酸水溶肥分别为49587.15元/hm^(2)和17.41元/kg;上等烟比例和中等烟比例最高的是济农含腐殖酸水溶肥和黄腐酸钾水溶肥分别为21.65%和63.29%。[结论]综合评价以济农含腐殖酸水溶肥和甲壳素水溶肥效果最优,与对照相比产值、均价、上等烟比例分别提高3324.75元/hm^(2)和2217.45元/hm^(2)、1.45元/kg和0.71元/kg、31.85%和19.42%。
[Objective]To study and compare the effects of four different kinds of humic acid water-soluble organic fertilizers on reducing weight,improving quality,increasing efficiency and reducing cost of flue-cured tobacco in Chuxiong tobacco-growing areas.[Method]A plot experiment was conducted to compare the treatment of applying four different kinds of humic acid water-soluble organic fertilizers to reduce the fertilizer consumption by 30%with conventional fertilization.[Result]Chitin water-soluble fertilizer for main agronomic characters of tobacco plants and dry and fresh weight of aboveground parts was superior to other water-soluble fertilizer treatment and control treatments.The highest yield and single leaf weight of waist leaves were“YD-3”full-effect humic acid water-soluble organic fertilizer,which was 3031.05 kg/hm^(2)and 10.14 g respectively.The highest output value and average price were 49587.15 yuan/hm^(2)and 17.41 yuan/kg of humic acid-containing water-soluble fertilizer in Jinong.The highest proportion of first-class tobacco and middle-class tobacco were Jinong humic acid-containing water-soluble fertilizer and potassium fulvic acid-soluble fertilizer,which were 21.65%and 63.29%respectively.[Conclusion]The comprehensive evaluation shows that Jinong humic acid-containing water-soluble fertilizer and chitin water-soluble fertilizer have the best effect.Compared with the control,the output value per mu,average price and the proportion of top-grade tobacco are increased by 3324.75 yuan/hm^(2)and 2217.45 yuan/hm^(2),1.45 yuan/kg and 0.71 yuan/kg,31.85%and 19.42%respectively.
