【摘要】：采用盆栽试验研究了以糠醛渣、腐植酸尿素等为主成分研制的盐碱土壤调理剂对玉米生长及土壤的改良效果。结果表明,在氮、磷、钾用量相同的情况下,与速效肥料处理相比,盐碱土壤调理剂处理的玉米生物量增加1.86%~48.56%,叶绿素含量增加2.60%~4.77%,植株的氮、磷、钾吸收量增加3.51%~64.2%,土壤有机质含量增加12.77%~14.28%,土壤氮、磷、钾增加0.70%~9.46%,土壤含水量增加11.29%~11.36%,土壤pH值下降0.03,土壤EC_(25)降低15.8%~20.10%。说明施用盐碱土壤调理剂能促进玉米生长,增强玉米叶片光合能力。
[Abstract]:A pot experiment was conducted to study the effects of saline-alkali soil conditioners, such as furfural residue and urea humate, on maize growth and soil improvement. The results showed that the same amount of nitrogen, phosphorus and potassium was used in maize growth and soil improvement. Compared with the available fertilizer treatment, the biomass of maize treated with saline-alkali soil conditioner increased by 1.86 and 48.56, the content of chlorophyll increased by 2.60 and 4.77, the uptake of nitrogen, phosphorus and potassium increased by 3.51 and 64.2and the content of soil organic matter increased by 12.777.28, and the contents of soil nitrogen and phosphorus increased. Potassium increased 0.70% and 9.46%, soil water content increased 11.29% 11.36%, soil pH value decreased 0.03, soil EC-25) decreased 15.810% and 20.10%. The results showed that application of saline-alkali soil conditioning agent could promote maize growth and enhance leaf photosynthetic ability.
