2种新型肥料对茎瘤芥生长及品质的影响

Effects of Two New Fertilizers on Growth and Quality of Tumorous Stem Mustard

茎瘤芥是我国特有的农业资源,湖南是茎瘤芥的主要产区之一。开展新型肥料对茎瘤芥影响研究有利于促进土壤地力长效化和化肥合理使用,对提升茎瘤芥产量及茎瘤品质、促进产业良性发展具有一定意义。本研究选择有机硅钙镁及左老师·根康2种新型肥料,探究其对茎瘤芥生长、产量及品质的影响。结果表明,增施有机硅钙镁能够增加茎瘤芥的株高,提高叶片质量、茎瘤质量、根质量,总产量达140.00±32.41 t/hm^(2),增产24.11%;还能显著提高干物质、可溶性糖及VC含量水平。增施左老师·根康能增加植株高度、须根数量,提高叶片质量、茎瘤质量、根质量,总产量达159.25±23.07 t/hm^(2),增产41.18%;还能显著提高干物质、可溶性糖含量,提高VC含量。同时增施有机硅钙镁+左老师·根康能提升植株高度,增加茎瘤质量,总产量117.53±20.63 t/hm^(2),增产4.19%;还能显著提高干物质、VC含量,提高可溶性糖含量,但效果不如有机硅钙镁和左老师·根康单独施用。因此认为,有机硅钙镁和左老师·根康对促进茎瘤芥的生长、提高产量及品质均有一定作用,特别是有机硅钙镁能显著改善品质,左老师·根康能显著提高产量,但两者无需同时施用。

Tumorous stem mustard is a unique agricultural resource in China,and Hunan is one of the main producing areas of tumorous stem mustard.Studying the effects of new fertilizers on tumorous mustard is conducive to promoting the long-term soil fertility and rational use of fertilizers,which is of certain significance for improving the yield and quality of tumorous stem mustard and promoting the healthy development of the industry.In this study,two kinds of new fertilizers,Organosilicon Calcium Magnesium(OCM)and Zuolaoshi Genkang(GK),were selected to explore their effects on the growth,yield and quality of tumorous stem mustard.The results showed that the plant height,leaf weight,stem nodule weight and root weight were increased by increasing the application of OCM,and the total yield was 140.00±32.41 t/hm^(2),and the yield increased by 24.11%.It could also significantly increase the content of dry matter,soluble sugar,and VC.The application of GK could increase the plant height,number of fibrous roots,leaf weight,stem nodule weight and root weight,and the total yield was 159.25±23.07 t/hm^(2),and the yield increased by 41.18%.It could significantly improve the content of dry matter and soluble sugar,and increase the content of VC.The application of OCM+GK could increase the plant height,increase the stem nodule weight,and the total yield was 117.53±20.63 t/hm^(2),which increased the yield by 4.19%.It could significantly increase the dry matter and VC content,as well as the soluble sugar content,but the effect was not as good as using OCM and GK alone.Therefore,it was concluded that OCM and GK had certain effects on promoting the growth,increasing the yield and quality of stem tumor mustard,especially OCM could significantly improve the quality and GK could significantly increase the yield,but they didn't need to be applied simultaneously.
