喷施硫酸镁对马铃薯产量的影响
Effects of Magnesium Sulfate Foliar Application on the Potato Yield
摘要
Abstract
This study investigated the effect of magnesium on the potato yield so as to provide a basis for the scientific application of magnesium fertilizer in potato production.Using two potato varieties,Zhuangshu 3 and Qingshu 10,4 treatments were established:foliar spraying of magnesium sulfate at 1.05,1.50,and 1.95 kg/ha,and an equal amount of water as control.Effects of these treatments on plant height,marketable tuber ratio,and yield were analyzed.Results showed that foliar application of magnesium sulfate significantly promoted plant height and improved both yield and the proportion of marketable tubers.The 1.50 kg/ha treatment showed the highest values in both Zhuanglang and Weiyuan experimental sites,with yields of 28 667.17 kg/ha and 57 223.39 kg/ha,representing yield increases of 6.7%and 5.5%over the water control,respectively.The marketable tuber ratios were 84.3%and 76.9%,respectively,which were 9.4 and 9.2 percentage points higher than the control.Therefore,foliar application of 1.50 kg/ha magnesium sulfate is more favorable for increasing plant height,marketable tuber rate,and yield of potatoes in Zhuanglang and Weiyuan Counties,and is recommended for promotion in potato production.关键词
