摘要
我国土地盐碱化日益严重,农业可持续发展受到严重阻碍,盐碱地改良迫在眉睫。以玉米先玉335为研究对象,在山西省清徐县徐沟镇的盐碱地条件下,探究新型改良剂乙酰化葡萄糖与尿素、磷肥和有机肥的不同配施组合对土壤的改良效果及对玉米生长发育的影响。结果表明,乙酰化葡萄糖、尿素、磷肥和有机肥混合施用对盐碱地改良效果最为显著,土壤pH值与对照相比降低了0.32;玉米叶片的SPAD值提高了50.834,净光合作用速率提高了21.8μmol/(m2·s);玉米拔节期和收获期的株高与茎粗均有极大增加,分别增加了45.99,0.36cm和77.13,0.50cm;玉米穗长、单穗质量、百粒质量以及穗粒数均有极大增加,分别增大了5.06cm、118.216g、11.123g和271.8粒。改良剂乙酰化葡萄糖与肥料的混合施用能促进作物生长并改善土壤理化性状,其可以作为未来盐碱地改良的重要措施之一。
The salinization of land in China is becoming more and more serious, and the sustainable development of agriculture is seriously hindered.Taking corn Xianyu 335 as the research object in this experiment, the effects of different combinations of acetylated glucose,urea,phosphate fertilizer and organic fertilizer on soil character improvement effect and effects of maize growth and development were investigated under the saline and alkaline land conditions in Xugou Town,Qingxu County,Shanxi Province. The results showed that the combination of acetylated glucose,urea,phosphate fertilizer and organic fertilizer had the most significant effect on the improvement of saline-alkali land. The pH of the soil was 0.32 lower than that of the control (without any treatment). The SPAD value of maize leaves increased by 50.834 and the net photosynthetic rate increased by 21.8 μmol/(m 2 · s). The plant height and stem diameter of maize at seedling uprooting stage and harvest stage increased by 45.99,0.36 cm and 77.13,0.50 cm,respectively. The ear length, ear weight,100-grain weight and grain number per ear of maize increased by 5.06 cm,118.216 g,11.123 g and 271.8 grains, respectively. The combination of acetylated glucose and fertilizer can promote crop growth and improve soil properties,which can be used as one of the important measures to improve saline-alkali land in the future.
