摘要
文章探究利用沼液源鸟粪石对酸性土壤改良的影响,并研究其对小白菜(Brassica chinensis L.)生长的影响。试验以沼液源鸟粪石与化肥对酸性土壤进行小白菜种植试验,研究土壤酸碱度及理化性质的变化,分析其对小白菜生长的影响情况。结果表明,利用沼液源鸟粪石可以提高土壤的酸碱度,从而改善土壤的理化性质。并且有效增加了小白菜叶绿素、可溶性糖含量,提高了小白菜鲜重、株高。沼液源鸟粪石既有利于酸性土壤的改良,又有利于提高小白菜的品质。
This paper explored the effect of using liquid digestate source struvite on the improvement of acidic soil and its effect on the growth of Chinese cabbage.The experiment used biogas slurry source struvite and chemical fertilizer to plant Chinese cabbage in acidic soil,the changes of soil pH and physicochemical properties were studied,and its influence on the growth of Chinese cabbage were analyzed.The results showed that the soil pH could be improved by using the biogas slurry source struvite,so as the physicochemical properties of the soil was improved.Moreover,the content of chlorophyll and soluble sugar,the fresh weight and plant height were all increased.
