为探明含海藻提取物液态有机肥料和含豆渣亚临界水解产物液态有机肥料在蔬菜上的施用效果,以白菜和莴笋为试验对象,开展了田间小区试验。供试肥料以追肥的形式浇施,共设置常规施肥(CK)、常规施肥+含豆渣亚临界水解产物液态有机肥料(T1)、常规施肥+含海藻提取物液态有机肥料(T2)等3个处理,测定了不同施肥处理下2种蔬菜的农艺性状、叶片叶绿素相对含量和氮含量、土壤理化性状等指标。结果表明:施用上述2种液态有机肥料可以刺激白菜和莴笋的须根生长,增加须根数量,促进蔬菜生长和增产;与CK处理相比,T1、T2处理的白菜和莴笋经济产量分别显著增加19.17%、22.24%和18.04%、16.85%;T1、T2处理能显著降低土壤pH及可溶性盐浓度(EC值),提高有机质含量,T2处理还能促进蔬菜对氮肥的吸收。
To clarify the application effects of liquid organic fertilizer containing seaweed extract and liquid organic fertilizer containing soybean residue subcritical hydrolysate on vegetables, Chinese cabbage and asparagus lettuce are used as test objects for a field plot experiment. The tested fertilizers are applied as top-dressing by pouring with three treatments: conventional fertilization (CK), conventional fertilization + liquid organic fertilizer containing soybean residue subcritical hydrolysate (T1), and conventional fertilization + liquid organic fertilizer containing seaweed extract (T2). Agronomic traits, leaf chlorophyll relative content and nitrogen content, and soil physical and chemical properties under different fertilization treatments are measured. The results show that applying the two liquid organic fertilizers can stimulate fibrous root growth of Chinese cabbage and asparagus lettuce, increase fibrous root number, and promote vegetable growth and yield increase. Compared with CK treatment, the economic yields of Chinese cabbage and asparagus lettuce in T1 and T2 treatments increase significantly by 19.17%, 22.24% and 18.04%, 16.85%, respectively. T1 and T2 treatments can significantly reduce soil pH and soil electrical conductivity value (EC value) while increasing organic matter content, and T2 treatment can also promote nitrogen fertilizer absorption in vegetable.
