微量元素水溶肥对大白菜生长和生理特性的影响

Effect of Different Temperature on Growth and Physiological Characteristics of Chinese Cabbage

本试验采用0.50、0.75、1.00、1.25 g/L四种浓度的微量元素水溶肥对大白菜进行叶面喷施,研究了不同浓度微量元素水溶肥对大白菜生长和生理特性的影响。结果显示,四种浓度微量元素水溶肥料处理的大白菜的植株高度、叶长、叶宽、鲜质量等形态指标均有明显提高,对植株可溶性蛋白含量、维生素C、叶绿素含量影响显著。高浓度处理效果优于低浓度处理,其中,1.00 g/L处理的大白菜叶最长;播后35 d,株高最大;维生素C含量最高,植株硝酸盐的降低效果最佳。以上结果表明,微量元素水溶肥料的叶面喷施促进了大白菜的生长发育,提高了大白菜的品质和风味,其中以1.00 g/L处理的效果最佳。

In this experiment,microelement water-soluble fertilizers with concentrations of 0.50,0.75,1.00,1.25 g/L were applied to the leaf surface of Chinese cabbage,to study the effects of microelement fertilizers with different concentrations on the growth of Chinese cabbage.The result showed that under the 4 comcentration of microelement soluable fertilizer treament,the plant height,leaf length,leaf width,fresh weight,were improved.The effect of high concentration treatment was better than that of low concentration treatment.Among them,1.00 g/L treatment had the longest leaf length;35 days after sowing,the plant height was the highest;The content of vitamin C was the highest;The effect of nitrate reduction was the best.Overview,the growth,quality,flavor of Chinese cabbage had been improved by the microelement soluable fertilizer and 1.00 g/L is the best concentration.
