锌钼微肥对鲜食油菜生长及品质的影响

Effect of Application of Zn and Mo Microelement Fertilizer on the Growth and Quality of Rape

通过盆栽试验,研究了土壤栽培条件下不同的锌钼微肥处理对鲜食油菜鲜重、干重、叶绿素、Vc、可溶性固形物含量及硝酸盐含量的变化情况.结果表明,锌钼微肥各处理均能不同程度地促进鲜食油菜的生长,提高产量和改善品质,并且以单施钼肥对降低硝酸盐的积累最有利.以锌钼微肥配施对增加鲜食油菜的干重、鲜重、叶绿素、Vc及可溶性固性物含量最有效.同时表明,在试验时期内油菜移栽后25～32天生长和品质达到最优.

A pot experiment was conducted to study the dynamic changes of yield and quality of rape after application of different content of Zn and Mo microelement fertilizer in room. The results showed that all different treatments of Zn and Mo microelement fertilizer could increase rape yield and improve rape qualities. Compared with other treatments,application of Mo microelement fertilizer was the most effective to reduce the rape NO3^--N content,and application of Zn and Mo microetement fertilizer was the most effective to increase rape fresh weight,dry weight,chlorophyll content,Vc content and soluble solid content. And in the different rape growth periods, from 25 days to 35 days after rape being transplanted the growth and quality were the best.
