功能性有机肥对大白菜生长的影响

在海南省农业科学院永发试验基地开展大棚试验,研究施用促生长型功能性有机肥对大白菜农艺性状、产量、品质和土壤微生物丰度等指标的影响。结果表明,施用功能性有机肥能显著促进大白菜的生长,且以添加高浓度促生菌效果最优。大白菜移栽后第20天,施用添加2%促生菌的功能性有机肥的大白菜株高比对照(CK)提高30.5%,叶片宽增加24.9%。与施用普通有机肥和CK相比,施用功能性有机肥后,大白菜收获期产量增加,可溶性糖和维生素C含量更高,土壤微生物群落结构改善。

Effect of functional organic fertilizer on growth of Chinese cabbage

Greenhouse experiment was set at Yonfa experiment station, Hainan Academy of Agricultural Sciences, to study the effect of functional organic fertilizer on Chinese cabbage. It was shown that application of functional organic fertilizer could promote the growth of Chinses cabbage, and the effect was better for the functional organic fertilizer with higher content of plant growth-promoting rhizobacteria (PGPR). After 20 d of transplantation, the height and leaf width of Chinese cabbage were increased by 30.5% and 24.9%, respectively, with application of functional organic fertilizer containing 2% PGPR compared to the control (CK). The yield, soluble sugar and vitamin C contents were also increased with application of functional organic fertilizer compared to CK and normal organic fertilzer, and the soil microbial community structure was improved.
