沼液施用量对淡涂泥田小麦产量的影响

摘要

Biogas slurry is a kind of typical high -quality organic manure. Taking wheat variety Yangmai No. 12 as the tested material, the effects of biogas slurry application on the yield of wheat were initially explored under the field plot test condition. The results showed that increasing the application amount of biogas slurry had obvious yield - increasing effect on wheat. The combination of applying 75000 kg/hm2 biogas slurry as base fertilizer and applying 37500 kg/hm2 biogas slurry as topdressing obtained the highest yield, being 12.26% higher than that of CK (without biogas slurry application). Therefore, the reasonable application of biogas slurry had positive effect on wheat production in coastal lightly - coated mud Geld in eastern Zhejiang province.%沼气发酵残余液(沼液)是一种典型的优质有机肥料.本研究在田间小区试验条件下,以小麦品种杨麦12号为材料,就沼液作为肥源对小麦产量形成的影响做了初步探讨.研究结果表明:增施沼液对小麦具有明显的增产效果,但以基肥施用沼液75000 kg/hm2、追肥施用沼液37500 kg/hm2处理的小麦产量为最高,与不施沼液的对照相比,增加产量达12.26％.因此合理利用沼液,对浙东沿海淡涂泥田小麦生产具有积极的作用.
