摘要:

为探讨纳米碳对作物生长发育因子的响应,明确复合肥配施纳米碳对作物的影响,以甘薯为研究对象,设计了复合肥与纳米碳通过单独浇窝、喷雾和浇窝加喷雾不同配施处理方式比较试验,研究不同处理对甘薯成活率、农艺形状、叶绿素SPAD值及产量品质的影响。试验结果显示:复合肥配施纳米碳通过栽插薯苗时每窝用1.0 kg 1000倍纳米碳液浇窝,同时在栽植后30 d,再用1000倍纳米碳液均匀喷雾茎叶,可以有效提高2种甘薯的成活率,对淀粉型‘商薯19’和鲜食型甘薯‘烟薯25’的产量分别提高3.51%和10.67%,同时提高淀粉型‘商薯19’的淀粉含量和鲜食型甘薯‘烟薯25’的可溶性糖含量。因此,在甘薯生产中,按照此方法应用复合肥配施纳米碳可以有效的提高甘薯的产量和品质,促进甘薯产业健康发展。

Abstract:

To explore the response of nano-carbon to crop growth and development factors, and to clarify the impact of compound fertilizer combined with nano-carbon on crops, sweet potato was used as the research object, and a comparative experiment of compound fertilizer and nano-carbon was designed with different combined application methods, such as single watering, spraying and watering plus spraying. The effects of different treatments on the survival rate, agronomic shape, chlorophyll SPAD value, yield and quality of sweet potato were studied. The experimental results showed that the survival rate of two kinds of sweet potato could be effectively increased by using 1.0 kg 1000 times of nano-carbon solution per litter to irrigate the litter when the potato seedlings were planted with nano-carbon combined with compound fertilizer, and then spraying the stems and leaves with 1000 times of nano-carbon solution evenly 30 days after planting. And the yield of the starch type ‘Shangshu 19’ and the fresh eating type sweet potato ‘Yanshu 25’ increased by 3.51% and 10.67% respectively. Meanwhile, the starch content of the starch type ‘Shangshu 19’ and the soluble sugar content of the fresh eating type sweet potato ‘Yanshu 25’ improved. Therefore, applying compound fertilizer combined with nano-carbon according to this method can effectively improve the yield and quality of sweet potato and promote the healthy development of sweet potato industry.
