1.提高种子质量(1)采用夏、秋花生留种。实践证明,南方采用秋花生留种、北方采用夏花生留种,是花生全苗、增产的重要措施。由于花生是自花受粉作物,年年用春花生留种,又作春种,长期在相同的条件下繁殖,容易造成种子退化而减产。另外,用春花生留种,由于生长期长,加之收获后贮存 1. improve seed quality (1) the use of summer and autumn peanut species. Practice has proved that the use of autumn peanut species in the South, summer peanut species in the North, peanut seedlings, an important measure to increase production. Since peanuts are self-pollinated crops, perennial spring peanut species, but also for spring species, long-term breeding in the same conditions, easily lead to seed degradation and yield. In addition, the use of spring peanut species, due to the long growing season, combined with storage after harvest
