尾菜发酵沼液替代化肥对娃娃菜种植土壤肥力及菜品品质的影响
Effects of fermented biogas slurry of tail vegetables instead of chemical fertilizer on planting soil fertility and quality of Chinese baby cabbage
摘要
Abstract
[Objective]The study aims to investigate the effects of using vegetable waste fermentation biogas slurry to replace chemical fertilizers on the soil fertility of Chinese cabbage(Brassica rapa var.pekinensis)cultivation and the quality of the cabbages.It also seeks to screen out the optimal replacement ratio of chemical fertilizers with the biogas slurry.This research provides a theoretical basis and scientific evidence for solving the difficult problem of disposing of vegetable waste in the main production areas of high-altitude summer vegetables,improving soil fertility,and achieving high-quality cultivation of Chinese cabbages.[Method]"Jintong"Chinese baby cabbage were used as the test material,and the field positioning experiment was conducted for two consecutive years in 2023 and 2024,and five treatments were set up under the condition of equal nitrogen amount,including five treatments,namely CK(0%biogas slurry,conventional chemical fertilizer treatment),T1(25%biogas slurry+75%chemical fertilizer),T2(50%biogas slurry+50%chemical fertilizer),T3(75%biogas slurry+25%chemical fertilizer)and T4(100%biogas slurry),to analyze the effects of different biogas slurry dosage on soil fertility,the quality and yield of Chinese baby cabbage.[Result]The content of soil organic matter was significantly increased under the treatment of biogas slurry replacing chemical fertilizers and there was a cumulative stacking effect for two consecutive years of application.Compared with the CK treatment,the increase in soil organic matter content under T1 to T4 treatments ranged from 6.28%to 22.77%and 36.73%to 52.01%,respectively;Biogas slurry instead of chemical fertilizer treatment could significantly increase the contents of soil total nitrogen,alkali-hydrolyzable nitrogen,available phosphorus and available potassium,and the pH showed an upward trend;The soluble sugar,soluble protein and vitamin C contents of Chinese baby cabbage were the optimal under the treatment of 75%chemical fertilizer replacement by biogas slurry,and the vitamin C contents of Chinese baby cabbage in the two years under the treatment of T1 to T4 were significantly increased compared with the treatment of CK,with the increases of 38.18%to 66.08%and 37.73%to 57.46%,respectively;The titratable acid showed a decreasing tendency with the increase in the amount of replacement by biogas slurry,but there was no significant change;The nitrate contents of baby cabbage under all biogas slurry treatments were lower than that of conventional fertilization in the two years,and the decreases were 16.53%-43.73%,13.36%-38.39%,respectively;With the increase of the proportion of biogas slurry substitution,the yield of Chinese baby cabbage showed a trend of increasing and then decreasing,and the yield of Chinese baby cabbage reached the highest in both years under T3 treatment,with a significant increase in yield of 27.81%and 23.05%respectively compared with CK treatment;Biogas slurry replacing chemical fertilizer treatment can save the cost of fertilizer inputs and improve the economic efficiency of Chinese baby cabbage.The highest income of Chinese baby cabbage was obtained in two years under T3 treatment,which increased by 29.0%,23.4%,respectively,compared with CK treatment,and the highest production/input ratio was 53.0 in both cases.[Conclusion]Considering factors such as soil fertility and the quality of baby Chinese cabbages,the fertilization treatment of returning vegetable waste fermentation biogas slurry to the field to replace 75%of chemical fertilizers(T3)is the optimal one.关键词
