摘要
Abstract
In order to explore the technology of maize topdressing in the Yellow River irrigation area of Ningxia,using Xianyu 1225 as an indicator variety,an experiment was conducted on foliar spraying of humic acid water-soluble fertilizer Folistim during the trumpet stage of spring maize to evaluate the feasibility of Folistim replacing urea for topdressing during the trumpet stage of maize.The results showed that under the same conditions of basal fertilizer(cow manure 30 m3/ha,maize formula fertilizer 450 kg/ha,diammonium phosphate 150 kg/ha),all treatments showed a certain increase in yield,where as significant increase in yields and income were detected for the following 2 treatments that was Folistim at 11 250 mL/ha with 750 kg of water at trumpet stage,and Folistim at 6 000 mL/ha with 750 kg of water and Folistim at 3 750 mL/ha with 750 kg of water 7 days before tasseling.The average grain yields for this 2 treatments were 15 778.5 kg/ha and 15 694.5 kg/ha,respectively,which increased by 5.00%and 4.44%compared to the conventional control(base fertilizer plus urea 225 kg/ha),respectively,achieving cost savings and efficiency increase of 1 778.1 and 2 156.6 Yuan/ha,respectively,which could be further promoted.关键词
