甘蔗间作花生播期筛选试验

Sowing date screening of peanut intercropping with sugarcane

以粤油7花生为间作试验材料,探索研究甘蔗间作花生不同播期对花生农艺性状、经济性状和产量指标的影响。结果表明,在同等管理和施肥条件以及保证甘蔗生长发育的前提下,以第3播期(3月15日)间套作表现最佳,花生株高一般,有效分枝最多,单株果数最多,产量最高,综合经济效益最高。

Taking Yueyou 7 peanut as material, the effect of sowing date on agronomic traits, economic traits and yield of peanut when intercropping with sugarcane was studied in this paper. The result showed that under the same management and fertilization conditions and on the premise of the growth of sugarcane, the 34 sowing date （15 March） was the best. Under the best sowing date, plant height of peanut was not the highest, but peanut had the most effective branches, the most pots per plant, and the highest yield. The 3^rd sowing date had the best comprehensive benefit.
