电气石尾矿对水稻生长发育、生理指标及产量的影响
Effect of Tourmaline Tailings on Rice Growth,Physiological Indicators and Yield
摘要
Abstract
The purpose of this study is to explore whether tourmaline tailings can promote crop growth,realize the resource utilization of tailings,and promote the integrated development of the first,second and third industries.Using tourmaline tailings as test material,and different proportion tailings were added to the soil.The growth and physiological indexes of rice were measured by combining indoor pot experiment with laboratory analysis test.The results showed that tourmaline tailings hindered the growth of plant height,root length and leaf length of rice seedlings,which decreased by 8.7%-10.3%,4.5%-32.0%and 8.7%-15.1%,respectively.And tourmaline tailings promoted root diameter and stem diameter of rice seedlings,increasing by 9.6%-15.4%and 0.9%-4.3%,respectively.The promotion effect of stem diameter increased with the increase of the proportion of addition.The small proportion of 1:30 was beneficial to the growth of plant height at reproductive stage,and was also beneficial to the growth of dry matter accumulation at seedling and mature stage.The dry matter of rice at seedling and maturity stage increased by 4.1%and 12.26%,respectively.The SOD activity in different growth stages and Pro content at jointing stage of rice were significantly negatively correlated with the yield,and the yield decreased by 0.1%-14.6%,which the addition of tailings was not conducive to the accumulation of rice output.The results showed that tourmaline tailings had a stress on the growth and development of rice,and did not improve the economic benefits of rice.Small proportion of tailings could promote the accumulation of dry matter in rice.关键词
