摘要:

为探寻化肥减量配施有机肥对烤烟生长和养分吸收利用的影响,以烤烟新品种贵烟5号为试验材料,采用二因素随机区组设计进行田间试验,设置3个化肥施用水平(A1,常规施肥;A2,减量20%;A3,减量40%)和2个有机肥配施水平(B1,750 kg·hm-2;B2,2 250 kg·hm-2),分析不同处理下烤烟生长、干物质积累与分配、养分吸收积累与分配等的变化。结果表明,化肥减量配施有机肥对打顶期贵烟5号的自然株高、自然叶数、打顶株高、留叶数、茎围、节距、最大叶长和最大叶宽等农艺性状并无显著影响。各处理相比,A2B2处理打顶期的根、茎,及整株干物质积累量,根的氮、磷积累量,茎的磷、钾积累量均显著(p<0.05)高于A3B1处理。在相同有机肥配施水平下,A3处理的氮、磷、钾肥农学利用率显著高于A1处理。综合来看,贵烟5号在生产中推荐在常规施肥基础上化肥减量20%并配施2 250 kg·hm-2有机肥的方案,可在减少化肥施用量的同时,提高烟株对养分的吸收利用率。

Abstract:

To explore the effects of chemical fertilizer reduction combined with organic fertilizer application on the growth, nutrient uptake and utilization of flue-cured tobacco, a field experiment was conducted using a two-factor randomized complete block design with a new flue-cured tobacco cultivar, Guiyan5, as the test material. Three chemical fertilizer application levels were set: A1 (conventional fertilization), A2 (reduction rate of 20%), and A3 (reduction rate of 40%), along with two organic fertilizer application levels: B1 (750 kg·hm-2) and B2 (2 250 kg·hm-2). Changes in growth, dry matter accumulation and partition, as well as nutrient uptake, accumulation and partition of flue-cured tobacco under different treatments were analyzed. The results showed that chemical fertilizer reduction combined with organic fertilizer application had no significant effects on the agronomic traits of Guiyan5 at the topping stage, including natural plant height, natural leaf number, topped plant height, retained leaf number, stem circumference, internode length, maximum leaf length, and maximum leaf width. Among all treatments, the dry matter accumulation of root, stem, and the whole plant, the nitrogen and phosphorus accumulation in root, and the phosphorus and potassium accumulation in stem under the A2B2 treatment at the topping stage were significantly (p<0.05) higher than those under the A3B1 treatment. At the same organic fertilizer application level, the agronomic efficiencies of nitrogen, phosphorus, and potassium fertilizers in the A3 treatment were significantly higher than those in the A1 treatment. Overall, the recommended fertilization scheme for Guiyan5 in production is a 20% reduction in chemical fertilizers based on conventional fertilization combined with 2 250 kg·hm-2 of organic fertilizer. This scheme can reduce chemical fertilizer input while improving the nutrient uptake and utilization efficiency of tobacco plants.
