【摘要】：以浙江省临安市板桥镇的田间蔬菜大棚为研究样地,采用空心菜Lpomoea aquatica-小青菜Brassica chinensis轮作模式,研究了死猪炭和竹炭对大棚蔬菜生长产量和土壤理化性质的影响。试验以不施用生物质炭处理为对照(ck),分别设置1次施用(一次性施加20 t·hm-2)与2次施用(20 t·hm-2均分2次施加)2种方式。结果表明:与对照相比,1次施用死猪炭处理显著(P0.05)提高了空心菜和小青菜土壤pH值,而竹炭处理对土壤pH值无显著性影响。1次施用和2次施用死猪炭处理使小青菜产量显著(P0.05)提高了44.14%和47.38%。而竹炭的2种处理却降低了第1茬空心菜产量。1次施用死猪炭和竹炭处理仅显著(P0.05)提高了空心菜根系全氮质量分数,对小青菜季根系全氮质量分数无显著性影响,而2次施用死猪炭处理显著(P0.05)使小青菜根系全氮质量分数提高了29.46%。死猪炭和竹炭的施用对土壤硝态氮质量分数、蔬菜地上部全氮质量分数均无显著性影响。与竹炭相比,施用死猪炭在改善土壤pH值、提高作物产量方面具有更好效果。此外,相比于2次施用,采用1次施用死猪炭的方式更为经济合理。
[Abstract]:The effects of dead pig charcoal and bamboo charcoal on the growth yield and soil physical and chemical properties of vegetable in greenhouse were studied by using Lpomoea aquatica-small green vegetable Brassica chinensis rotation model in Banqiao Town, Linan City, Zhejiang Province. In this experiment, no biomass carbon treatment was used as control, and two methods were set up: one time application (20 t 路m ~ (-2) at a time) and two times applying 20 t hm-2 twice. The results showed that compared with the control, the soil pH value of Dioscorea sinensis and Brassica chinensis was increased by applying dead pig charcoal once (P0.05). However, bamboo charcoal treatment had no significant effect on soil pH value. 1. 1 application and 2 times application of dead pig charcoal could significantly increase the yield of small green vegetables by 44.14% and 47.38%, respectively. However, the two treatments of bamboo charcoal decreased the yield of the first sprouts. 1 the application of dead pig charcoal and bamboo charcoal only significantly increased the total nitrogen content of the root system, but had no significant effect on the total nitrogen content of the root system in the young cabbage season. But twice application of dead pig charcoal significantly increased the total nitrogen content of root system by 29.46. The application of dead pig charcoal and bamboo charcoal had no significant effect on the nitrate content of soil and the total nitrogen content in the aboveground part of vegetables. Compared with bamboo charcoal, the application of dead pig charcoal has a better effect on improving soil pH value and increasing crop yield. In addition, it is more economical and reasonable to apply dead pig charcoal once than two times.
