酸性土壤改良剂对土壤理化与蔬菜产量的影响
Effects of Acidic Soil Amendment on Soil Physical and Chemical Properties and Vegetable Yield
摘要
Abstract
[Objective]The acidic soil amendment was used to improve acidic soil in vegetable garden of southern China so as to improve soil physical and chemical properties and vegetable yield.[Method]Before vegetable planting,the experiment was carried out by soil amendment application rates of 0 kg,25 kg,50 kg,and 75 kg per 667 m2.After harvest,soil physical and chemical properties and vegetable yield were measured.[Result]Application of soil amendment could improve soil pH value,reaching higher by 0.47 unit.When 75 kg per 667 m2 soil amendment was applied,total N,P and K content in soil were the highest,total N,P and K content in vertical soil layer were ranked in order that in 0～15 cm layer>16～30 cm layer>31～45 cm layer.Application of soil amendment could improve Ca,Mg and Si content in soil and balance soil nutrient.With the increasing content of soil amendment,Ca,Mg and Si content in soil were increased.In vertical soil layer,pH value,Ca and Si content in soil were ranked in order that 0～15 cm layer>16～30 cm layer>31～45 cm layer.With the increasing depth of soil layer,the effectiveness of soil amendments decreased.When 75 kg per 667 m2 soil amendment was applied,plant dry weight was the largest.[Conclusion]Acidic soil amendment could improve soil in vegetable garden and was suitable in field acidic soil improvement.关键词
