农家肥对盐碱土中玉米幼苗生理生化指标的影响
Effects of Farmyard Manure on Physiological and Biochemical Indexes of Maize Seedlings in Saline-alkali Soil
摘要
Abstract
[Objective] To study the effect of farmyard manure on saline-alkali soil in Daqing.[Method] A certain proportion farmyard manure was added in saline-alkali soil (farmyard manure∶ saline soil =1∶ 3) by the method of laboratory pot,then the changes of physiological and biochemical indexes of blade were determined at the three-leaf stage of corn to clarify the improvement effect of farmyard manure on saline-alkali soil.[Result] After adding farmyard manure,soluble protein content,malondialdehyde (MDA) content were significantly lower (P ＜ 0.05),and chlorophyll content significantly increased (P ＜ 0.05),soluble sugar content was not significant (P ＞ 0.05).[Conclusion] Farmyard manure can improve the salt and alkali damage of corn by reducing the peroxide effect of maize leaves and enhancing photosynthesis.The farmyard manure had a certain improvement effect on saline in Daqing soil.关键词
