摘要

为探究烤烟适宜的水磷耦合模式及其对氮、磷、钾养分吸收积累的影响。采用田间小区试验，试验设置3种灌水水平和施磷水平，分别为低水（W1：0.50 L/株）、中水（W2：1.00 L/株）、高水（W3：2.00 L/株）和低磷（P1：32 kg/hm2）、中磷（P2：64 kg/hm2）、高磷（P3：96 kg/hm2），研究了不同施磷量和灌水量条件下烤烟对氮磷钾养分吸收积累的影响。结果表明：施磷量相同时，灌水处理能够明显增加烟株对氮、磷、钾养分的吸收积累量，表现为：W3Pi > W2Pi > W1Pi > CKi（其中i=1或2或3）；当灌水量相同时，增加施磷量也有利于烟株对氮磷钾养分的吸收积累，且在施磷水平为96 kg/hm2时表现较好，表现为：WiP3 > WiP2 > WiP1；高磷水平下，灌水量为1.00，2.00 L/株时，W3P3和W2P3处理烟株对氮磷钾养分的吸收积累量差异不显著；烟株和根、茎、叶各器官对钾的吸收量高于氮和磷，氮、磷、钾在根、茎、叶器官中的分配顺序呈现叶>茎>根的变化规律；在烟株的不同生育期，对养分的吸收积累量和积累强度存在差异。烟株对养分的吸收积累主要在旺长期，烟叶是养分的主要吸收积累器官；施磷量为96 kg/hm2，灌水量为1.00~2.00 L/株的水磷耦合处理在促进烟株对氮磷钾养分的吸收积累方面效果较好。烤烟施肥中要注意调整氮磷钾的施用比例和水磷耦合配比。

Abstract

In this study

the optimal pattern for water-phosphorus coupling and its influences on Nitrogen (N)

Phosphorus (P) and Potassium (K) uptake and accumulation of flue-cured tobacco were studied

which provided scientific basis for the rational use of water-fertilizer resources in Qiandongnan prefecture tobacco land

Guizhou province. Three irrigation rates:0.50 L/plant (W1)

1.00 L/plant (W2) and 2.00 L/plant (W3)

and three P fertilizer application rates:32 kg/hm2 (P1)

64 kg/hm2 (P2) and 96 kg/hm2 (P3) were set in this field plot experiment. The results showed that

at the same P application rate

P and K uptake and accumulation of tobacco plant were significantly increased by irrigation. The order of N

P and K uptake and accumulation of each treatment was as follows:W3Pi > W2Pi > W1Pi > CKi (i=1 or 2 or 3). At the same water irrigation level

P and K uptake and accumulation of tobacco plant increased as P application rates increased. The P application rate of 96 kg/hm2 was beneficial for N

P and K uptake and accumulation. The order of N

P and K uptake and accumulation was as follows:WiP3 > WiP2 > WiP1. Under high P application treatment

irrigation rate of 1.00~2.00 L/plant

P and K uptake and accumulation were not significantly different between W3P3 and W2P3 treatment. The K uptake and accumulation of tobacco plant

leaf

stem and root were higher than N and P. The order of N

P and K distributed in root

stem and leaf was as follows:leaf > sti > root. The N

P and K uptake

accumulation and accumulation intensities of tobacco plant were different at different growth stages. Nutrients uptake and accumulation of tobacco plant occurred mainly at tobacco leaf and vigorous growth stages. The P application rate of 96 kg/hm2 and irrigation rate of 1.00~2.00 L/plant were suitable for N

P and K uptake and accumulation of tobacco plant. The optimal application rates of N

P and K fertilizers and water and phosphorus coupling should be paid attention to adjust in fertilizer application of tobacco.
