不同调酸措施对江西红壤稻田酸化防治及水稻产量的影响
Effects of Different Acid Regulation Measures on the Prevention and Control of Acidification of Red Soil Paddy Fields and Rice Yields in Jiangxi
摘要
Abstract
Aiming at the acidification of red soil paddy fields,this study compared the comprehensive effects of different acid regulation measures on soil acidification and rice yields,aiming to provide support for the establishment of a rice cultivation technology system with high and stable yields in acidified paddy fields in Jiangxi.The experiment was conducted on the red soil paddy field in Shexi Town,Shangyou County,Ganzhou City,Jiangxi Province.With the habitual application of chemical fertilizer(NPK)as the control,five acid regulation measures were designed,including NPK combined with lime(NPK+L),green manure(NPK+GM),organic manure(NPK+OM),straw(NPK+S),and lime+green manure+organic manure(NPK+L+GM+OM).The results showed that compared with the NPK treatment,five acid regulation measures increased the soil pH value.The soil organic matter content of the NPK+GM treatment was the highest,increasing by 6.25％.The content of alkali-hydrolyzable nitrogen,available potassium,and slow-release potassium in the soil with different acid regulation measures also increased to varying degrees.The NPK+L+GM+OM treatment had the best improving effect on rice yields,with increases of 4.50％in the yield of early rice and 6.10％in the yield of late rice.The NPK+GM treatment had the highest net income of rice planting,which increased by 1 450 yuan/hm2.关键词
