复合肥与腐殖酸配施对盐碱地改良及棉花生长的影响
Effect of Application of Humic Acid and Inorganic Fertilizers on Modifying Saline-alkali Soil and the Growth of Cotton
摘要
Abstract
In order to improve the utilization of fertilizer and improve the output of cotton in saline-alkali land , the effect of humic acid and inorganic fertilizers on modifying saline-alkali soil and the growth of cotton were analyzed .The results indicated that under the eguivalent level of inorganic nutrition ,the application of humic acid and inorganic fertilizers distinctly inhibited the increasing of soil salinity ,decreased soil pH value and in-creased the contents of organic matter .Compared to CK and application of inorganic fertilizers ,the yield of cot-ton was increased by 17 .7% and 5 .8% .The contents of available nitrogen and phosphorus and potassium in soil were increased by 5 .7% ,33 .1% and 24 .4% compared to applying inorganic fertilizers .关键词
