通过开展间作花生品种筛选、行距配置及播期覆膜试验,测定不同间作模式下花生农艺性状和产量,分析木薯、花生间作的综合效益,研究木薯/花生间作的高产高效栽培模式。结果表明,在6个参试花生品种中,桂花771最适合与木薯间作种植,其产量比当地对照种桂花17增加了18.7%,其次是桂花22和桂花836;在间作模式筛选试验中,中窄行距下(0.9~1.1 m)1行木薯间作2行花生的产量效益明显高于宽行距(1.3 m)下1行木薯间作3行花生,覆盖地膜间作花生的经济效益高于不覆盖地膜处理,木薯与花生相隔15 d间作种植的产量效益高于同时种植木薯和花生处理。总体而言,选用桂花771作为与木薯间作的花生品种,采用1行木薯间作2行花生的行距配置,且花生比木薯提前15 d并覆盖地膜种植的产量效益最好。
The peanut agronomic traits and yield under different intercropping patterns were determined by screening intercropped peanut varieties, spacing configuration and sowing date. The comprehensive benefit of cassava and peanut intercropping was analyzed, and the high yield and high efficiency cultivation mode of cassava / peanut intercropping was studied. The results showed that among the six varieties tested, sweet-scented osmanthus 771 was the most suitable for intercropping with cassava, its yield increased by 18.7% compared with that of local sweet-scented osmanthus 17, followed by osmanthus fragrans 22 and osmanthus 836. In the intercropping model screening test, The yield of peanut in row 1 of cassava intercropping with narrow row spacing (0.9 ~ 1.1 m) was significantly higher than that of row 1 of row intercropping cassava with width of row (1.3 m). The economic benefit of covering peanut intercropped with mulching film was higher than that of uncoated mulching , The yield benefit of planting cassava and peanut 15 days apart was higher than that of planting cassava and peanut. Overall, the sweet-scented osmanthus 771 was chosen as the peanut variety intercropped with cassava, and the row spacing of 2 rows of peanut intercropped with 1-row cassava was used. The yield of peanut was 15 days ahead of cassava and covered with plastic film.
