【摘要】 本试验主要利用温室盆栽试验研究了蔗渣生物炭5个不同施用量(施用量为每千克土壤施加0、10、20、40、60 g)对菜心产量及品质的影响,旨在为应用生物炭在菜心种植中达到稳产、增产以及提升品质的目的提供参考。试验结果表明,蔗渣生物炭在一定的施加水平下对菜心的产量和品质具有促进作用。当蔗渣生物炭施加量为40 g/kg时,蔗渣生物炭使菜心鲜重和维生素C含量显著升高,分别达25.18%和6.59%,当蔗渣生物炭施加量为60 g/kg时,蔗渣生物炭使菜心株高、可溶性糖含量和蛋白质含量显著升高,分别为15.64%、37.40%和27.72%。蔗渣生物炭可以施加于菜心以提升菜心的产量和品质,但合适施加量需要根据菜心实际生产来确定。更多还原

【Abstract】 This experiment mainly studied 5 different application rate of the bagasse biochar fertilizer using pot experiment(0, 10, 20, 40, 60 g fertilizer per kilogram soil) about their effects on the yield and quality of flowering Chinese cabbage, in order to provide reference for the application of biochar in cabbage planting for the purpose of stable and increased yield and quality. The test results showed that application of bagasse biochar on a certain level has positive effect on yield and quality of flowering Chinese cabbage. When the application reate is 40 g/kg, the fresh weight and vitamin C content of Chinese cabbage bagasse was significantly increased by 25.18% and 6.59%, respectively. When the application rate increased to 60 g/kg, the plant height, the content of soluble sugar and protein was significantly increased by 15.64%, 37.40% and 27.72%. Bagasse biochar can be applied to Chinese cabbage in order to improve the yield and quality, but the suitable application rate needs to be decided according to the actual production of the vegetable.更多还原
