施用含硒有机肥对粉葛产量及硒吸收转运的影响

Effects of Selenium Containing Organic Fertilizer on Yield Selenium Absorption and Transport of Pueraria Lobata

为了探讨含硒有机肥对粉葛生长的影响,选取2块试验田X和Y,并将粉葛产量和硒吸收转运速率作为研究指标,在试验田X中运用根施法,在试验田Y中运用液态叶面喷施法,发现:当根施量控制在18000~24000 kg/hm^(2),叶面喷施量控制在45000~55000 kg/hm^(2),可以大大提升粉葛生长速率和品质,硒吸收转运能力更强。

In order to explore the effect of selenium containing organic fertilizer on the growth of Pueraria lobata,two experimental fields X and y were selected,and the yield and selenium absorption and transport rate were taken as the research indexes.The root application method was used in experimental field X and the liquid foliar spraying method was used in experimental field Y.it was found that when the root application rate was controlled at 18000-24000 kg/hm^(2) and the foliar spraying rate was controlled at 45000-55000 kg/hm^(2),It can greatly improve the growth rate and quality of Pueraria lobata,and has stronger selenium absorption and transport capacity.
