摘 要:以先玉335为供试品种,设置不同基肥、基肥与种肥分施、基肥与种肥混施以及基肥、种肥施用位置等处理方式,研究基肥、种肥施用技术对玉米早期干物质积累、根系生长及产量的影响。结果表明,在农民习惯一次性施肥条件下,FP1-5-8处理(基肥施用位置在种子侧方5 cm,下方8 cm)的产量比FP1-5-5处理(基肥施用位置在种子侧方5 cm,下方5 cm)提高8.0%,在玉米苗期具有一定的优势。4种不同基肥种类磷酸二铵(DAP)、磷酸一铵(MAP)、硝酸磷(NPF)、硫酸铵+过磷酸钙(AS+MCP)综合壮苗效果和产量效应来看,磷酸二铵(DAP)处理的干物质积累量和根系生长在苗期表现出明显优势,DAP>AS+MCP>MAP>NPF。基肥与种肥混施(B-S-Mix)处理的产量和苗期植株生长与基肥与种肥分施(B-S-Split)处理相比均有一定幅度提高,将种肥施用在种子侧方5 cm、下方5 cm的位置更为合适,且壮苗效果更明显。Xianyu335 was used as the experimental variety, different basal fertilizer, basal fertilizer and seed fertilizer silted or mix, fertilizer placement were designed to study the dry matter accumulation, root growth and yield on maize of the basal and seed fertilizer application technology. The results showed that FP 1-5-8 treatment (basal fertilizer placement was in seed side 5 cm, below 8 cm) yield was 8.0% higher than FP2-5-5 treatment(basal fertilizer placement was in seed side 5 cm, below 5 cm), and had better growth at seeding stage; DAP treatment showed obvious advantage of dry matter accumulation and root growth at seeding stage, from effect of strong seeding and yield for four types of different basal fertilizer, DAP〉AS+MCP〉MAP〉NPF; the yield and plant growth of B-S- mix treatment was better than that of B-S-split treatment, the more appropriate seeding fertilizer placement was in seed side 5 cm, below 5 cm, and had stronger seeding performance.
