增施葡萄糖和草酸对低养分盐渍棉田棉花生长及产量的影响
Effects of Additional Glucose and Oxalic Acid Application on Cotton Growth and Yield in a Low-Nutri-ent Saline Cotton Field
摘要
Abstract
To clarify the effects of additional glucose and oxalic acid application on cotton growth and yield formation in a low－nutrient saline cotton field under conventional fertilization,a two－year field experiment was conducted.A completely randomized design was adopted with four treatments:CK(conventional fertilization only),AC100%(conventional fertilization+oxalic acid),GL100%(con-ventional fertilization+glucose),and GL50%+AC50%(conventional fertilization+glucose+oxalic acid).Glucose and oxalic acid were applied in split doses through drip irrigation under plastic mulch.Seedling emergence rate,plant height,stem diameter,dry matter ac-cumulation and partitioning,and yield components were measured.The seedling emergence rate was significantly affected by year and treatment.In 2025,the emergence rate under GL100%and GL50%+AC50%was significantly increased by 19.60%and 29.56%,re-spectively,compared with that under CK.At the boll－opening stage,the greatest plant height was observed under GL50%+AC50%in both years,being about 12.14%－15.12%higher than that under CK,whereas the largest stem diameter was recorded under GL100%,being 19.92%－21.91%higher than that under CK.A more pronounced advantage in dry matter accumulation per plant was shown under GL100%,and both total dry matter per plant and boll dry matter were significantly increased.The highest seed cotton yield was obtained under GL50%+AC50%in both years,with increases of 56.63%in 2024 and 66.34%in 2025 relative to CK.In conclusion,additional application of glucose and oxalic acid on the basis of conventional fertilization promotes cotton emergence,growth,and yield formation under low－nutrient saline conditions,and GL50%+AC50%shows the best overall performance.关键词
