喷施废菌棒木醋液对小白菜生长和品质的影响

为研究废菌棒所制木醋液对蔬菜生长和品质的影响,以稀释100、300、500、700倍木醋液进行小白菜叶面喷施试验,测定不同处理对小白菜及土壤各项指标的影响。结果表明:不同稀释倍数的废菌棒木醋液均能提高小白菜株高和鲜重,提高Vc含量,促进还原性糖的积累和降低硝酸盐含量;稀释500倍木醋液对小白菜品质效果最显著,Vc和可溶性糖含量分别提高31.56%、31.55%,硝酸盐降低37.77%;喷施稀释100倍木醋液对土壤pH值、速效钾、有效磷和碱解氮均有显著效果;废菌棒木醋液中主要有机成分有37种,分别是有机酸类、酮类、酚类、醇类等。

Effect of spraying wood vinegar made from mushroom cultivation wastes on the growth and quality of Chinese cabbage

The effects of wood vinegar prepared by mushroom cultivation wastes sticks on the growth and quality of vegetables were studied,the leaves of Chinese cabbage were sprayed with 100,300,500 and 700 times diluted wood vinegar,and various indexes of Chinese cabbage and soil with all treatments were determined.The results showed that different dilutions of wood vinegar increased the plant height and fresh weight of Chinese cabbage,increased the content of Vc,promoted the accumulation of reducing sugar and reduced the nitrate content.The dilution of 500 times wood vinegar had the most significant effects on the quality of Chinese cabbage.The contents of Vc and soluble sugar increased by 31.56%and 31.55%,respectively,and the nitrate decreased by 37.77%.Spraying 100 times wood vinegar solution had significant effect on soil pH,available potassium,available phosphorus and alkali-hydrolyzed nitrogen.There are 37 kinds of organic components in the waste wood vinegar,including organic acids,ketones,phenols and alcohols.
