Effect of Field Application of the Mixed Controlled-Release Fertilizer on High Quality Ecological Tobacco Leaf
摘要
Abstract
To optimize the fertilization mode of controlled-release fertilizers for high-quality ecological tobacco production,a randomized block experiment was conducted from April to October in 2022 and 2023 using Xiangyan No.7 as the test material.Conventional split fertilization was used as the control(CK).Based on the nutrient release time ratio after transplanting,five controlled-release fertilizer treatments were set up,which were treatment A(0 d+25 d),treatment B(0 d+25 d+50 d),treatment C(0 d+25 d+50 d+75 d),treatment D(0 d+25 d+50 d+75 d+100 d),and Treatment E(0 d+25 d+50 d+75 d+100 d+125 d).A comparative analysis was performed on tobacco yield,photosynthetic population parameters,and morphological indicators under different treatments.The results showed that treatment D achieved the highest yield,with a two-year average increase of 2.39%compared to CK,indicating a significant improvement.During the vegetative growth period(from rosette to budding),compared to CK,plant height in treatments C and D increased by 7.43%and 8.21%,respectively,the number of leaves per plant increased by 1.2-1.5,leaf length increased by 6.01%and 7.99%,and leaf width increased by 3.55%and 4.01%,respectively.Treatment E showed the best morphological development in the upper leaves,with leaf length and width increasing by 2.68%-3.03%compared to CK.Comprehensive analysis indicates that treatment D effectively coordinates the photosynthetic efficiency and morphological development of tobacco,contributing to improved yield in ecological tobacco-growing areas.关键词
