双螯合速效生态有机肥在生菜上的应用

Application of Double Chelation Quick-acting Eco-organic Fertilizer in Letture

为了提高有机肥料利用率,以帝皇结球生菜为材料,研究双螯合速效生态有机肥在露地条件下不同施用量对生菜产量和品质的影响。结果表明:有机肥用量15 000kg·hm-2的处理对生菜产量和品质的影响最大,株高达到11.73cm、叶长为23.13cm、叶宽为19.60cm、叶片数为21.13片、叶绿素含量为49.107mg·dm-2、单球重为543.0g、可溶性糖含量45.20g·kg-1、每100g生菜中维生素C含量为138.0mg,其次为有机肥用量10 000和20 000kg·hm-2的处理。

In order to improve the utilization rate of organic fertilizers,taking Dihuang head lettuce as testing material,the effects of double chelation quick-acting eco-organic fertilizer on yield and quality of lettuce in the open field were studied. The results showed that effect of organie fertilizer dosage of 15 000 kg. hm-z on the yield and quality of lettuce was the maximum, the plant height was 11.73 cm, the length and width of leaves were 23.13 cm and 19.60 cm,number of leaves was 21.13,the chlorophyll content was 49. 107 mg.dm-z ,the weight of single fruit was 543. 0 g. The content of soluble sugar and vitamin C per 100 g fruit were 45.20 g.kg-a and 138.0 mg,treatments of organic fertilizer dosage of 10 000 and 20 000 kg.hm-~ were lower.
