施腐植酸量对西芹产量及养分吸收利用的影响
Effect of Humic Acid Fertilizer Application Amount on Yield and Nutrient Uptake of Celery
摘要
Abstract
To identify the proper humic acid fertilizer dosage of facility celery,the authors used random block design to study the effect of different humic acid fertilizer application amount on celery's yield,nutrient content,nutrient absorption amount and nutrient absorption and utilization efficiency.The results showed that the celery fresh weight and dry weight of overground part increased with the increase of the application amount,and then decreased;compared with CK,the increasing rate of fresh weight was 5.33％ to 7.78％,and that of dry weight was 5.32％ to 7.89％;H138 had the highest increment,then was H184.The application of humic acid fertilizer could significantly increase the content of N,P and K and the absorption amount of N,P and K and the absorption and utilization efficiency of N,P and K in celery,and H138 had the most obvious effect.Therefore,the optimum dosage of humic acid fertilizer should be 138 kg/hm2 for facility celery.关键词
