施用有机肥对草皮田复耕土壤肥力和水稻产质量的影响
Effects of Organic Fertilizers on Soil Fertility and Rice Yields and Quality in Re-Cultivated Turfgrass Fields
摘要
Abstract
A pot experiment was conducted to evaluate the effects of three commonly used commercial organic fertilizers(chicken manure,rapeseed cake,and bio-organic fertilizer)applied individually or in combination at equal rates in addition to chemical fertilizer application on soil fertility,rice yield,and grain nutrient content in re-cultivated turfgrass fields.The results showed that compared with the application of only chemical fertilizer,the additional application of organic fertilizers increased the content of dissolved organic carbon(DOC),available phosphorus(AP),and available potassium(AK)in soil by 11.9%-42.8%,35.3%-115.1%,and 18.8%-58.9%,respectively.Organic fertilizer application improved the integrated fertility index(IFI)by 75.6%-95.4%,with the single application of chicken manure showing the greatest improvement.The sole application of chicken manure significantly increased the rice grain yield by 38.8%.Organic fertilizer application altered the nutrient content in rice grains.Both individual applications and combined application of rapeseed cake and bio-organic fertilizer significantly increased the nitrogen(N)content in rice grains.All three organic fertilizers applied individually significantly decreased the calcium(Ca)and manganese(Mn)content in rice grains.The single application of rapeseed cake significantly increased the zinc(Zn)content in rice grains.Bio-organic fertilizer applied alone significantly increased the Ca content in rice grains.The combined application of chicken manure and rapeseed cake at a ratio of 1:1 significantly increased both iron(Fe)and Zn content in rice grains.The content of N,Ca,Mg,Fe,Mn,and Zn in rice grains were within the appropriate ranges of rice nutrients.In conclusion,the application of chicken manure was an effective measure for soil fertility and rice yield enhancement in re-cultivated turfgrass fields.关键词
