| 摘 要： | 为简化农艺措施,降低生产成本,本研究采用田间试验方法,以无机复混肥常规浅施基追结合的施用方法作对照,研究了腐植酸复合肥深松分层一次性施用技术对玉米全生育期土壤含水量、玉米生长发育及产量的影响。结果表明:腐植酸复合肥深松分层一次性施用能使10～90cm土层内土壤的含水量平均提高7.16%,玉米抽雄期和灌浆期叶面积指数分别提高了19.3%、14.0%,表征叶绿素含量的SPAD值分别提高了24.5%、18.5%,增加了玉米各部位的鲜干重,降低了株高,增加了茎粗,且玉米产量构成因素、穗部特征得到明显改善,最终显著提高玉米产量16.06%,达到11 883kg/hm2。

| Abstract: | A field experiment was conducted to study the effects of different fertilizer and fertilization technology on soil water content,maize growth and yield.The results indicated that,compared with the technology of applying conventional inorganic fertilizer,applying HA compound fertilizer in different soil layers could increased 10-90 cm soil layers’ water content by 7.16%,the head sprouting and grain filling’s leaf area index increased by 19.3%、14.0%,SPAD increased by 24.5%、18.5%,corn biomass and dry matter accumulation were all increased.In addition,plant height was reduced,strain thick was increased,corn yield and its constitutes were all enhanced.Finally,increase maize yield by 16.06%,reach to 11 883 kg/hm2. |
