摘要

为探讨不同氮磷钾配比对柑桔砧木幼苗营养生长的影响,在2021年和2022年连续两季进行了田间试验。在不同氮磷钾配比(2:1:1和1:1:2)和对照(1:1:1)条件下,研究不同氮磷钾配比对柑桔砧木幼苗生长参数的影响。4月初和试验季施肥,每枯落水按不同比例(1:1:1、2:1:1和1:1:2)分别施氮、磷、钾0.5 g。处理采用随机完全区组设计,每个处理3个重复。在两个试验季节获得的结果明显表明,与对照相比,所有处理的生长参数都显著增加。一般来说,在本研究中,特别是以2:1:1的比例的N、P、K在统计上最有效。

Effect of fertilizer ratios between N, P, and K on enhancing vegetative growth of Cleopatra mandarin seedlings
This field experimental work was conducted during successive seasons (2021 and 2022) to explore the effect of different fertilizer ratios between nitrogen (N), phosphorus (P) and potassium (K) on the vegetative growth of Cleopatra mandarin rootstock seedlings ( Citrus reshni L.). The seedlings were subjected to different fertilizer ratios between N, P and K (2:1:1 and 1:1:2) as well as the control (1:1:1) for investigating their effect on some growth parameters of Cleopatra mandarin rootstock seedlings. All fertilizer ratios were applied at the beginning of April and during the experimental seasons using 0.5 g of N, P, and K mixed with ratios different (1:1:1, 2:1:1 and 1:1:2) for every litter of irrigation water. The treatments were distributed as randomized complete block designs with 3 replicates for each treatment. The results obtained during both experimental seasons revealed obviously that all treatments have significantly increased growth parameters as compared to control. Generally, N, P and K with a ratio 2:1:1 particularly were statistically the most effective in this study.
