在田间自然的土壤气候下,进行大白菜施用腐植酸生物有机肥效果试验。结果表明,与CK相比,施用腐植酸生物有机肥,大白菜叶绿素a含量增加0.02~0.05 mg/g·FW,叶绿素b含量增加0.06 mg/g·FW,抗病性提高;大白菜单株重增加0.13~0.75 kg,净菜率提高5.3%~12.1%,最高增产率为26.27%;其品质和口感有所改善,Vc含量提高16.3~33.2 mg/kg,可溶性固形物含量提高0.7%~1.1%。因此,腐植酸生物有机肥适宜在大白菜上大规模推广应用。 In the natural soil climate in the field, Chinese cabbage humic acid bio-organic fertilizer effect test. The results showed that compared with CK, the humic acid bio-organic fertilizer increased the content of chlorophyll a by 0.02-0.05 mg / g FW and the content of chlorophyll b by 0.06 mg / g FW, The weight gain increased by 0.13-0.75 kg, the net food rate increased by 5.3% -12.1%, and the highest yield increased by 26.27%. The quality and taste of the product increased. The Vc content increased by 16.3-33.2 mg / kg and the soluble solids content increased by 0.7% -1.1 %. Therefore, humic acid bio-organic fertilizer suitable for large-scale promotion of Chinese cabbage.
