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。Effects of saline-alkaline soil conditioner on the growth of maize and the improvement of soil were studied using pot experiment. The saline-alkaline soil conditioner was made of furfural residue,humic-acid-urea and other ingredients. The results showed that compared with chemical fertilizer treatment,for the saline-alkaline soil conditioner treatments,the maize biomass increased by 1. 86% to 48. 56%; Chlorophyll content increased by 2. 60% to 4. 77%,plant nitrogen,phosphorus and potassium uptake increased by 3. 51% to 64. 2%. Soil organic matter content increased by 12. 77% to 14. 28%,the soil nitrogen,phosphorus and potassium content increased by 0. 70% to 9. 46%. Soil moisture content increased by 11. 29% to11. 36%,soil pH fell 0. 03. Soil EC25 reduced by 15. 8% to 20. 10%. All this suggested that saline-alkaline soil conditioner promoted the growth of maize,enhanced the photosynthetic capacity of maize leaves.
