Effect of combination of Sulfate-potassium magnesium on Citrus reticulata Blanco cv. tankan
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 12
Abstract
"The effects of different rates of sulfate-potassium magnesium fertilizer include 20.7, 41.4, 62.1, 82.8 kg/667 m2 on foliar nutrient content, agronomic characters, fruit quality, yield and planting benefit of Citrus reticulata Blanco cv. tankan under medium K and deficient Mg in soil were studied. The results showed that the application of sulfate-potassium magnesium could increase the foliar content of potassium 0.04 to 0.11 percentage point and magnesium 0.04 to 0.08 percentage point, and increase the number of fruit per plant 7.8 to 27.5. The vitamin C content was increased significantly by 1.16 mg/100g to 4.63 mg/100g, the yield increased by 4.3% to 19.5%, and the benefit increased by 7.0% to 33.6%, respectively. With applying sulfate-potassium magnesium 62.1 kg/667 m2, the single fruit weight was the heaviest, the number of fruit per plant was the most, the fruit was the largest, the content of vitamin C was the highest, the content of organic acid was the lowest, and the yield and the plantation income were the highest."
