化肥减量配施黄腐酸对盐渍化土壤养分及花生生长的影响
Effects of reducing fertilizer and applying fulvic acid on soil nutrients and peanut growth
摘要
Abstract
[Objective]In order to explore the application effect of combined application of chemical fer-tilizer and humic acid organic fertilizer on saline soil and peanuts.[Methods]A peanut pot experiment is conducted.A combination of humic acid organic fertilizer and fertilizer application were applied in this experi-ment,and conventional fertilizer application rates were taken as a control.On the basis of basic application of humic acid organic fertilizer of 40 kg/667m2,a total of 6 treatments were set up to reduce the conventional dosage of nitrogen,phosphorus,and potassium fertilizers by 20％,40％,60％,80％,and 100％.And by analyzing the changes in soil nutrients,peanut plant height,lateral branch length,chlorophyll content(SPAD value),dry matter accumulation and yield of plants,and other indicators,the effects of fertilizer reduction and organic substitution fertilization models on salinization soil nutrients and peanut growth were studied.[Results]After basic application of humic acid fertilizer,a significant reduction in fertilizer application could still main-tain the normal growth of peanuts.Reducing fertilizer application by 20％-40％could significantly promote peanut growth,increase soil nutrient content,effectively improve saline soil,improve soil quality,and also in-crease the dry matter accumulation,chlorophyll content,number of fruit per plant,and fruit weight per plant of peanuts,thereby increasing yield.[Conclusion]The optimal technical solution for the combination of chemical fertilizer and humic acid organic fertilizer is to reduce the application of chemical fertilizer by 20％to 40％on the basis of applying 40 kg/667m2 of humic acid fertilizer.关键词
