大量元素水溶性肥料对生菜农艺性状及产量的影响

摘要

研究大量元素水溶性肥料对生菜农艺性状及产量的影响，结果表明：喷施大量元素水溶性肥料可以显著提高生菜的产量及产值，桂林市七星区生菜产量比喷施等量清水、空白对照分别提高6.10%、7.53%，分别增收2085.75、2110.50元/hm2；钦州市钦北区生菜产量比喷施等量清水及空白对照提高6.44%、7.40%，分别增收3287.25、3303.00元/hm2。%Effects of macroelement water soluble fertilizer on lettuce agronomic traits and yield were studied.The results showed that spraying water soluble fertilizer could significantly improve the yield and output value of lettuce.The yield increased by 6.10%,7.53% and output value increased by 2 085.75,2 110.50 yuan/hm2 compared with spraying water and blank control in Qixing District of Guilin City;At the same time,the yield increased by 6.44%,7.40% and output value increased by 3 287.25,3 303.00 yuan/hm2 compared with spraying water and blank control in Qinbei District of Qinzhou City.
