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。
Pot experiments were conducted to study the effect of saline-alkali soil conditioner on the growth of corn and the improvement of soil by using furfural residue and humic acid urea as main components. The results showed that under the same nitrogen, phosphorus and potassium conditions, compared with the quick-acting fertilizer treatment, the corn biomass treated with saline-alkali soil conditioner increased 1.86% -48.56% and the chlorophyll content increased 2.60% -4.77% The contents of N, P, K increased by 3.51% ~ 64.2%, while the content of soil organic matter increased by 12.77% ~ 14.28%. The contents of N, P and K increased by 0.70% ~ 9.46% and the soil moisture increased by 11.29% ~ 11.36% Decreasing 0.03, soil EC_ (25) decreased 15.8% ~ 20.10%. This shows that the application of saline-alkali soil conditioner can promote the growth of maize and enhance the photosynthetic capacity of maize leaves.
