摘要 针对重庆榨菜产区土壤酸化、肥力下降,榨菜产量降低、品质变差、种植效益减少的问题,开展了生物炭有机肥对榨菜主要性状、产量、品质及效益的影响研究。结果表明,榨菜优良地方品种“永安小叶”在增施生物炭有机肥的情况下,其株高、开展度显著增加,单株叶重和瘤茎重明显增加,瘤茎皮筋减少,空心率略有增大,干物率增加,粗蛋白含量增加,叶片产量增加显著,瘤茎产量提高,收益增加,榨菜种植效益/成本均大于未施生物炭有机肥的常规处理,在常规施肥条件下,增施生物炭有机肥1 050 kg/hm2时,瘤茎产量达46 904.25 kg/hm2,净收益8 507.55元/hm2,效益/成本达1.43,榨菜提质增效明显。

Abstract In recent years, there are some problems in Chongqing mustard production area, such as soil acidification, fertility decline, yield decline, quality deterioration and planting benefit reduction. The effects of biochar organic fertilizer on main characters, yield, quality and benefit of mustard were studied. The results showed that the plant height, development degree, leaf weight per plant and tuber weight of Yonganxiaoye, an excellent local variety of mustard tuber, increased significantly with the application of biochar-based fertilizer, while the skin gluten of tuber decreased, the hollow rate increased slightly, the dry matter rate increased and the crude protein content increased under the condition of conventional fertilization and increasing application of biochar organic fertilizer, the yield of tuber reached 46 904.25 kg/hm2, the net income was 8 507.55 yuan/hm2, the benefit/cost was 1.43, and the quality and efficiency of tuber were improved significantly.
