新型有机无机复混肥对油菜产量及硝酸盐含量影响

通过盆栽试验,研究了新型有机无机复混肥对油菜产量及硝酸盐含量的影响。结果表明:新型有机无机复混肥能够显著提高油菜产量,降低硝酸盐含量,当施肥量为中肥水平时,其作用最明显;油菜鲜质量、叶绿素含量均随着施肥量的增加而增加,而在不同施肥水平下有机无机复混肥处理的油菜硝酸盐含量均比相应的化肥处理低,且二者之间差异显著,有机无机复混肥对油菜体内硝酸盐积累具有明显的抑制作用。

Effect of New Organic/Inorganic Mixed Fertilizer on Rape Yield and Nitrate Content

To study a new type of organic and inorganic mixed fertilizer on rapeseed yield and nitrate content,a pot experiment was conducted.The results showed that the new organic and inorganic mixed fertilizers could significantly improve the yield and reduced the content of nitrate when the amount of fertilizer is at middle level and the effect was the most obvious.With the increase of fertilizer,rape fresh weight and chlorophyll content increased.But under different fertilizer levels,in the organic and inorganic ...
