摘要
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。
Under the natural climate, the effects of humic acid biological organic fertilizer was tested with Chinese cabbage test in the field. The results showed that compared with CK, the content of chlorophyll a and chlorophyll b in Chinese cabbage using humic acid biological organic fertilizer were significantly increased 0.02 - 0.05 mg/g.FW, 0.06 mg/g·FW respectively, and improved disease resistance. With the increase of single plant weight from 0.13 0.75 kg, the rate of minimally processed vegetables correspondingly increased 5.3% - 12.1%, the highest yield rate was 26.27 %. Meanwhile, because the content of vitamin C （16.3 - 33.2 mg/kg） and soluble solids （0.7 % - 1.1%） increased, the quality and mouth feel improved. Therefore, humic acid biological organic fertilizers are suitable for large-scale popularization and application on Chinese cabbage.
