摘要
为解决花生连作障碍问题,明确甘薯-花生轮作对花生连作障碍的缓解效应,在多年花生连作地块,研究了甘薯-花生轮作(GHZ)与花生连作(HHZ)2种栽培模式下花生的营养生长、生理特性、产量及品质。结果表明:对比HHZ处理,GHZ处理显著促进了花生营养生长,提高了花生叶面积指数、叶绿素含量、净光合速率和光合生产能力;硝酸还原酶活性和根系活力提高;花生干物质积累量增加,荚果产量提高了14.4%,出仁率提高。此外,GHZ处理显著增加了花生籽仁蛋白质含量、粗脂肪含量及O/L比值,降低可溶性糖含量,改善了花生籽仁品质。甘薯-花生轮作可有效缓解花生连作障碍。
In order to solve the problem of peanut continuous cropping obstacle,and clarify the alleviation ef⁃fect of sweet potato peanut rotation on peanut continuous cropping obstacle,the nutritional growth,physiological characteristics,yield and quality of peanut under two conditions of sweet potato peanut rotation(GHZ)and peanut continuous cropping(HHZ)were studied in peanut continuous cropping plot for many years.The results showed that GHZ treatment significantly promoted the growth of nutrition,increased the leaf area index,chlorophyll content and net photosynthetic rate of peanut,increased the photosynthetic capacity,nitrate reductase activity,root activity,dry matter accumulation,pod yield and kernel rate.In addition,compared with HHZ treatment,GHZ treatment signifi⁃cantly increased protein content,crude fat content and O/L ratio of peanut kernel,decreased soluble sugar content and improved peanut kernel quality.Sweet potato peanut rotation can alleviate the obstacle of peanut continuous cropping.
